If you encounter problems with the dump and restore backup suite, please contact the maintainers and send them a detailled bug report. dump-0.4b46/TODO0000644002013200001440000000215712725723271010253 00000000000000Need to verify: --------------- 1. Verify that dump works with kerberos authentification (this was ported from *BSD and was not tested - in fact, this wasn't even compiled in!). Need success reports for this. Urgent items (for the next stable version): ------------------------------------------- All others: ----------- 1. More documentation? Examples, crontab? 2. Explore and correct dump problems on active filesystems (lseek/read negative count) (This should be OK as of 0.4b14. Unfortunately, this seems to continue for a very few users). 3. Reimplement the ext2 specific code in a "backend" and make the dump code more generic. This would allow creation of other backends for other filesystems. Implementing a (v)fat backend should be quite easy, as for BSD ffs (we already have the code for this). The BSD code in traverse.c (all those #ifdef _BSD) should go into the ffs backend. 4. Implement a DEBUG option which doesn't fork on each tape, making it able to debug dump with gdb. 5. Make a bootable dump tape? I don't know if it is possible... 6. Better readline completition in restore (escape spaces etc). dump-0.4b46/config.h.in0000644002013200001440000001347312763343254011612 00000000000000/* config.h.in.

With the dump -z6 compression on a 900 MHz Pentium III I had no problems with speed=4 which is the maximum speed for my burner. It looks as if at least speed=6 would be possible on a 900 MHz Pentium III. If speed is to large, cdrecord's input fifo gets empty (as shown by cdrecord) and then you have a buffer underrun. - replace the wayplay command with something which alerts you if you have to change CDROMS - for restore or verification replace /dev/cdrom by something which applies for you (device for the CDreader) DON'T FORGET to generate a boot-CD which has the 0.4b24 restore or a newer version of restore on board I prefer timos_Rescue_Cd_Set-0.6.1 see http://rescuecd.sourceforge.net Please Cc bug-reports to jarausch@igpm.rwth-aachen.de ----------------------------------------------------------------- This file and the scripts were slightly edited when the Helmut Jarausch patch was integrated in dump-0.4b24.

I use rsh in both directions. This may easily be changed to ssh. Basically three scripts are now necessary. The first wraps around the dump-command, the second acts as user exit when CD has to be changed and the third has to be run on the remote box. To make things easier I put the first two into one file called dump-to-remote-cd. The second file called get-dumpdata-to-cdrecord must be copied to the box with the CD-Burner. There is a small configuration section in it to get cdrecord to work. dump-to-remote-cd may be called with the capacity of the media which is used and / or a filesystem argument passed to dump.

Data is encrypted before it is written to tape, and decrypted when read. We use no padding or salt, so the data size doesn't change. Tools that use rmt for remote tape access (such as dump, restore and tar) can manipulate encrypted data without modification. The symmetric cipher is currently hardwired as Blowfish. [...] Building ermt: - Ensure that openssl-0.9.7a or later is installed. - Configure and build the package, enabling ermt support: ./configure --enable-ermt make This will build an extra binary: rmt/ermt, the encrypting version. If ermt fails to link because EVP_CIPHER_CTX_set_padding is undefined, you must upgrade to openssl-0.9.7a or later. Run-time setup: - Create a user for remote tape access, which we will call "dump": useradd -m dump - ermt reads the secret key from ".ermt.key". Generate a random key in ~dump/.ermt.key: su - dump openssl rand -out .ermt.key 32 chmod 400 .ermt.key Due to the way "openssl enc -kfile $file" reads the key file, you should ensure that the key contains no \0 or \r or \n characters, which would prematurely truncate the key length. - Protect the key: copy to many floppies, "od -x .ermt.key|lpr", etc. - Set up rsh access from root (or whoever you run dump as) to dump@localhost: # still running as user dump here echo localhost root > .rhosts chmod 400 .rhosts Or use ssh if you prefer; details left as an exercise. - Check that it works: run "rsh localhost -l dump date" as root. - Copy the ermt binary you built above to ~dump, and change dump's shell to ~dump/ermt. Backup usage: just dump remotely to localhost: dump -0u -f dump@localhost:/dev/st0 / restore -i -f dump@localhost:/dev/st0 # You can use GNU tar too If your device is doing hardware compression, it's best to turn it off, since encrypted data compresses very poorly. Emergency decrypting: if you need to restore a tape and don't have access to a host running ermt, you have two choices: - If you have a copy of the ermt binary, run it with the -d switch to decrypt stdin to stdout: dd if=/dev/st0 bs=10k | (cd ~dump; ./ermt -d) | # assuming ermt is in ~dump restore -i -f - - If not, use the OpenSSL "openssl" command, which does the same thing: dd if=/dev/st0 bs=10k | openssl enc -d -kfile ~dump/.ermt.key -blowfish -nosalt -nopad | restore -i -f - Versions of OpenSSL before 0.9.7a don't understand -nopad, so they won't work. How much does encryption slow down backups? In my tests, the network hop is the bottleneck: dumping unencrypted (i.e. standard rmt) to localhost is 38% slower than dumping directly to tape. Adding encryption makes no difference, which isn't surprising. Change log: 2003-04-08: added configure --enable-ermt, separate ermt binary 2003-04-06: Initial release -- Ken Lalonde dump-0.4b46/examples/cron_dump_to_disk/0000755002013200001440000000000012763343254015157 500000000000000dump-0.4b46/examples/cron_dump_to_disk/README0000644002013200001440000000302312706161134015745 00000000000000Here is how to use these backup scripts: 1. Create a separate backup partition big enough to hold all the filesystems you want to backup + any changes. Preferably, get a big inexpensive ide drive, and dedicate it as a backup drive. 2. Create the mount point for the partition as /backup (otherwise, modify the config parameters at the top of the scripts). 3. Mount the partition read-write, cd into /backup, and extract the backupskel.tar.gz there. This will create the directory structure needed by the scripts. 4. Set the partition to be mounted as read-only in your /etc/fstab. This will protect your precious backup from software crashes. 5. Copy the backup scripts "backup" and "backup_rotate" to a suitable directory in cron's path; "/usr/bin" is a good location. alternatively, you can place them anywhere, and modify the crontab entries to match, or run it manually. 6. Modify your /etc/crontab file to add these entries, and be sure to modify the times to suit your preferences, and the performance of your machine: ----------%<---------------------------------%<-------------------------------- # Perform Nightly Backup (nightly incremental + weekly full + monthly full) 02 06 * * 1-6 root backup_rotate ; nice -1 backup inc 02 06 * * sun root backup_rotate ; nice -1 backup full 07 00 01 * * root backup_rotate monthly ; backup full nodumpdate ----------%<---------------------------------%<-------------------------------- Any questions?

In fact, I'm a newbie. But I've been picking things up as I implement it here and I wanted to pass some of those things along in the form of a very basic FAQ. -Patrick Walsh 1) Introduction/ Non-rewinding device 2) Dump command line 3) Sending 2 or more filesystems to a tape 4) Compressing dumps on the fly 5) The "nodump" file and directory attribute. 6) Restoring your dumps (including compressed). 7) How to confirm a backup (highly recommended) 8) What are the best buffer size options? 9) Experiencing bread, lseek, lseek2 errors. 10) Example backup script 1) Introduction/ Non-rewinding device You use dump to backup to a file or a tape device. If you're backing up to a tape device, then the first thing you need to understand is that there are two devices that refer to your tape drive. There is the "rewinding" device and the "non-rewinding" device. I wish I could tell you an easy way to figure out what your device names are, but I don't know one. On my local box I had a /dev/tape device that linked to /dev/st0. It turns out that /dev/st0 is my "rewinding" tape drive. If I write to this device it will always rewind before starting to write. This means that if you try to dump two filesystems, only the second one will be stored. If your tape device is /dev/st0, like mine, then your non-rewinding tape device is probably /dev/nst0. Anyway, through the rest of this I will refer to $TAPE and $RWTAPE. $TAPE is the non-rewinding device (in my case /dev/nst0) and $RWTAPE is the rewinding tape (in my case /dev/st0 and /dev/tape). $FS is the filesystem you are backing up, such as /dev/hda1. 2) What options should I use? Use the man page to figure out what options to send to dump. I use "dump 0uanf $TAPE $FS". u=update /etc/dumpdates after a successful dump a=auto-size -- bypass all tape length calculations and write until eof n=notify 'operators' group when dump needs attention f=backup to file or device specified, or - for stdout 3) You want to send two or more filesystems to tape. OK, rewind using the mt command, then dump multiple times to the non-rewinding device, and you're done: mt -f $TAPE rewind dump 0uanf $TAPE $FS1 dump 0uanf $TAPE $FS2 etc. Check the man page of mt if you want to know how to eject the tape or retension it or anything. 4) You want to compress your dumps on the fly. No problem. Send your backup to STDOUT and manipulate it from there. It's easier if you're sending your output to the hard drive: dump 0uanf - $FS | gzip -c > /backup/outfile.dump.gz You want that to be written to the tape on the fly? Try this: mt -f $TAPE rewind dump 0uanf - $FS |gzip -c |dd if=- of=$TAPE [ You can also use the -z or -J options of dump in the recent versions to enable internal compression - stelian ] 5) You read the man page and you're wondering what the heck a "nodump" flag is. For example, how can you get dump to stop backing up /tmp or ~/.netscape/cache. You have two options: either exclude the inode in your dump command, or flag the files and directories with the "nodump" flag. To flag /tmp, for example, do this: chattr -R +d /tmp Want more details? Try 'man chattr' and 'man lsattr'. 6) You want to know how to restore your backup. Read the restore man page. But barring that, the easy way is to use restore in interactive mode. If you have three filesystems on one tape and you want to restore files from the second one, you need to do this: mt -f $TAPE rewind mt -f $TAPE fsf 1 # skip forward one file restore -if $TAPE OK, suppose now that you used the commands in section 4 to compress the dump file before it was written to disk. Use this command: mt -f $TAPE rewind mt -f $TAPE fsf 1 dd if=$TAPE of=- |gzip -dc |restore -rf - Obviously if you dumped to a file instead of a tape it is much easier: gzip -dc $filename |restore -rf - 7) How to confirm your backup Check out the restore man page and read up on the -C option. 8) What are the best buffer size options? Bernhard R. Erdmann answered this question on the dump-users mailing list. His excellent response follows: >> While I was doing google searches, there seems to be >> an issue regarding the default buffer size writing >> to tape. According to some, the default buffer size >> of 512 can harm modern drives. I have a Seagate >> DDS3 unit and am wondering what the best mt/dump >> options are.

The reason for this is that when AIX reads fixed >block length data in variable block mode, a check >condition is issued by the tape drive on every read. >AIX must interpret every check condition and determine >the proper action to take. This often will put the >tape drive into a mode of reading that will require >the tape drive to stop tape motion, rewind the tape >some distance, then start reading again. This will >reduce the life expectancy of the tape and increase >the time it takes to backup data. 9) Experiencing bread, lseek, and lseek2 errors. These errors are caused by inodes being changed during the backup. This is normal because dump and the Linux kernel are both acessing the filesystem and there is no consistence checking. By "calming" the system (killing unnecessary processes), you decrease the likelihood of having these errors. Read up on the bug on Sourcefourge: http://sourceforge.net/tracker/index.php?func=detail&aid=204909&group_id=1306&atid=101306 Note that the only "real" solution to this problem is to dump a unmounted filesystem or use a filesystem snapshot feature (like in LVM). 10) That about sums up my knowledge on the matter, but I feel better having written something for other peopleto look at so it doesn't take them quite so long to learn the things I did. I've included my backup script below. There are much better ones floating around, so go find someone else's and use theirs if mine won't work for you or you don't understand it. #!/bin/csh # System backup script for NARNIA # This is a script that will backup the entire hard drive # to the NT server (not my choice) \\fs1. # # On each Sunday night, a full backup will be made # of the hard drive and each day of the week thereafter an incremental # backup will be made that captures only those changes since the night # before. # Each full backup will be sent to the local tape as well as to the # NT machine. # # The files will be stored in partition-specific files with integer # endings that specify the day of the week they were saved.

I have tried to minimize changes in the BSD source and some parts may look ugly. dump/tape.c is really awfull but this is pure BSD code :-) Maybe, I should replace it with a simpler and cleaner version. 2. Kerberos mode is _NOT_ tested. 3. Some users related possible problems when dumping active (mounted) filesystems. The problems are reported as lseek and read error messages (with a negative count). If you encounter this kind of problems, please report them to the author. dump-0.4b46/NEWS0000644002013200001440000021235112763343221010254 00000000000000Changes between versions 0.4b45 and 0.4b46 (released Sep 05, 2016) =================================================================== 1.

Fix an issue with multi volume backups, which breaks restoring of files which are splitted on two or more volumes and are starting on 2nd tape or later (RedHat bug #507948). 3. Fix a bug in dump when dumping files with holes. This bug was introduced in 0.4b42 while adding ext4 support. (Sourceforge bug #3133762). 4. Fix a bug in restore -P where useless index files for compressed dumps were created (Debian bug #583093). Thanks to Mark Wooding for the patch. 5. Fix SYS_clone invocation on s390 architectures (Sourceforge bug #3303235). Thanks to Adam Tkac for reporting the bug. 6. Fix static builds. Thanks to Peter Volkov for the patches. 7. Fix false negatives in configure zlib test. Thanks to Bear Giles for the patch. 8. Add quick regression script from Bear Giles . 9. Fix a bug introduced in 0.4b43 causing restore to crash when asking for a new volume when doing multi-volume restores. Thanks to Patrik Schindler for reporting the bug. Changes between versions 0.4b42 and 0.4b43 (released June 11, 2010) =================================================================== 1. Fix a bug in dump making impossible to handle large toc files (> 2 GB). Thanks to X DUGi for reporting the bug (Sourceforge bug #2820629) 2. Fix 'restore -x' in multi-volume mode, which caused files being spanned on the first and second volumes to be incorrectly extracted. Thanks to Adam Tkac for reporting the bug. (there may be several bug reports about this issue, including Sourceforge bug #2117008, RedHat bugs #232415 and #444958). 3. Remove -lselinux -lsepol from the standard libraries list, they shouldn't be needed if selinux is not enabled in dump (this also fixes a build failure when selinux libraries are not installed). 4. Fix restoration of extended attributes of fifos and device nodes. Thanks to Igor Zhbanov for the bug report. 5. Don't attempt to set extended attributes on files that were not extracted in 'restore -N' mode. Thanks to Jan Grig for the patch. 6. Make the dump man page explicit about ext4 support. 7. Fix a bug in dump which caused EA entries to be unrecognizable by restore in some corner cases. Add a workaround to restore making it able to properly deal with those corrupted EA entries. Thanks to John Austin for reporting the bug. 8. Fix some issues when restoring a dump which was generated using exclusion patterns (either via -e or via the nodump attribute) (see the Debian bug #574667 for details. Thanks to Frdric Brire for the bug report and the associated patch. 9. Fix progress/estimated blocks display in dump when doing really huge backups. Thanks to Steve Bonds for the bug report and tests. (Sourceforge bug #2987758) 10. Improve level 1 dump speed by rearanging the "mapdirs" code. Thanks to Andreas Kies for finding the bottleneck and sending a patch (Sourceforge bug #2998119). 11. Use only ctime in order to compare newness instead of both ctime and mtime. This should both speed up dumping time and correct some side-effect bugs (like dumping files with an mtime in the future in every incremental backup). Thanks to Kieran Clancy for reporting the bug (Sourceforge bug #2999207). 12. Extract dumped UNIX sockets instead of ignoring them. (Sourceforge bug #3007216). 13. Compiler warning fixes (mainly warn_unused_result ones). Changes between versions 0.4b41 and 0.4b42 (released June 18, 2009) =================================================================== 1. Fix printout of the 'Connection to' message in dump/restore. Thanks to Dale Wiles for the bug report and its fix. 2. Fix dump -w/-W output for filesystems having the last backup level equal to 0. Thanks to Pascal Bouchareine for reporting the bug. 3. Enable restore to handle restoring onto a different SELinux policy from the dump. Thanks to Tony Nelson for the patch. (see http://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=189845 for details) 4. Fix EA set failures when restoring immutable files. Thanks to Andrew Kroeger for the patch. 5. Fix "mode file too large" errors when restoring huge backups. Thanks to Kenneth Porter for the bug report. 6. Add the ability to link against libtinfo library if present, instead of libtermcap or libncurses libraries. Thanks to Adam Tkac for the patch. 7. When comparing a backup, do not consider to be an error the fact that we encounter files created while dump was in progress. Thanks to Kenneth Porter for the bug report. 8. Force '-a' to be the default value when running 'restore -C'. Thanks to Kenneth Porter for the bug report. 9. Many improvements to the 'cron_dump_to_disk' example. Thanks to Aaron S. Hawley for the patch. 10. Fix the QFA generation when extended attributes are backuped along with the inodes. Prior to this fix, the entries for some inodes may get corrupted (duplicated entries or incorrect ones), making the QFA file unusable for repositionning in restore. Many thanks to Kenneth Porter for the bug report and the testing of the fix. 11. Fix EA restoration in debug mode (Sourceforge bug #1986216). 12. Stefan Auracher noticed that the Tower of Hanoi backup strategy documented in the man page wasn't actually based on the Tower of Hanoi algorithm. The man page was updated accordingly. 13. Fix missing level information from dump output when using the default level (RedHat bug #493635). Thanks to Adam Tkac for the patch. 14. Fix the dump man page to reflect the fact that the default dump level is 0 not 9 (RedHat bug #356121). Thanks to Adam Tkac for the patch. 15. Fixed a few spelling errors in the man pages (RedHat bug #489853). Thanks to Adam Tkac for the patch. 16. Fixed restore man page and program usage which incorrectly stated that -P and -A were both allowed in the same invocation (RedHat bug #490627). Thanks to Adam Tkac for the patch. 17. Use sys_clone under Linux to share I/O contexts between dump processes, thus drastically increasing the performance of dump under CFQ (which is the default I/O scheduler used in a number of distributions). Thanks to Jeff Moyer for the patch. 18. Add (preliminary) ext4 support - thanks to libext2fs which does all the job for us. Thanks to Gertjan van Wingerde for the patch. Changes between versions 0.4b40 and 0.4b41 (released January 2, 2006) ===================================================================== 1. Fix restore of dumped Access Control Lists. The previous code for EA works fine, but ACLs needed conversion from the ext2/3 disk format to posix_acl format before restoring. 2. Fix some issues with restoration of EA on big endian platforms. 3. Fix restore when the symtab is over 2GB in size. 4. Made the directory hash indexing an optional feature, accessible by the '-H' option of restore, and disable it by default. 5. Fixed dump to not include extended attributes information in the toc (archive) file which confused restore -t. Changes between versions 0.4b39 and 0.4b40 (released May 2, 2005) ================================================================= 1. Changed restore to emit warnings (instead of emitting a fatal error) if a file (or a directory) is unavailable for a comparision (if the user doesn't have the necessary permissions to access it for example). Thanks to Kenneth Porter for the bug report. 2. Re-done the 'do not save directory entries to non-dumped inodes (excluded from dump)' feature. The previous implementation worked well for excluded directories but not for regular files. Thanks to Kenneth Porter for the bug report. 3. Fixed a bug in dump where the tape size was miscalculated when the user used -d/-s to specify the tape characteristics. Thanks to Philip Goisman for reporting the bug. 4. Fixed another bug introduced in restore with the hashtree implementation. This one caused restore to stop saying "removenode: non-empty directory" in some cases. 5. Added support for dumping and restoring ext2/3 extended attributes (EA), like the access control lists (ACL) or the security labels used by SELinux. Changes between versions 0.4b38 and 0.4b39 (released January 21, 2005) ====================================================================== 1. The newly added dump_on_cd_3 example was buggy, replace it with an updated version from Andrew Basterfield . 2. Made restore to chdir() back into the initial directory when dumping core while aborting a comparision operation. The previous behaviour was to write the corefile at the root of the directory being compared, which could very well be read only and preventing the corefile generation. Thanks to Kenneth Porter for the bug report. 3. Silenced the failure to call fgetflags() when comparing an entry which has no ext2 attributes (as in lsattr()). 4. Fix a brown paper bug in restore -C which broke restore and caused modifications on the filesystem being compared (directories containing a file with the same name as the directory get renamed to RSTTMP...). Thanks to Kenneth Porter for finding the bug and helping me reproduce it. 5. Made restore -C force the -N flag (no writing allowed on the disk) in order to prevent more bugs like the above one. Changes between versions 0.4b37 and 0.4b38 (released January 7, 2005) ===================================================================== 1. Fix a couple of troff syntax bugs in the man pages. Thanks to Eric Raymond for the patch. 2. Made restore use either libncurses or libtermcap, depending on which one is available at configure time. 3. Fixed restore negative size display bug when comparing a dump containing files over 2GB. Thanks to Steve Bonds for the bug report. 4. Do not save directory entries to non-dumped inodes (excluded from dump). This will eliminate the 'missing file' warnings when doing 'restore -C'. 5. Fix dump crash when backuping a huge (2TB) filesystem, due to a bogus calculation on the inode map size. Thanks to Kevin B. Haines for submitting the bug and testing the fix. 6. Fix a problem in restore where the final \0 in the symbolic link names could have been lost, generating corrupt filenames. Thanks to Kyle Wilson for reporting the bug. 7. Implemented a hash list for the directory names in restore. The linear list used before caused problems in interactive restores when dealing with directories having thousands of entries. Thanks to Brian Ristuccia for reporting the bug. 8. Improved restore -C, this time including the directory attributes into the comparision. 9. Made restore understand tapes containing EA/ACLs (which will be dumped by the next version of dump). In this version extended attributes on the tape are ignored, for full EA/ACL support wait for the next version or try the experimental EA patch. Changes between versions 0.4b36 and 0.4b37 (released July 7, 2004) ================================================================== 1. Added the --enable-staticz configure option which enables dump and restore to be linked with static versions of libz and libbz2 (and dynamic versions of all other libraries). This will make Debian users happy, because libz and libbz2 were the only needed libraries living in /usr, all the others live in /lib. In case of system emergency, it is better not to have to rely on an extra filesystem. Thanks to Bdale Garbee for the suggestion. 2. Fix compilation on (at least the Linux Debian port to) AMD64. ( defines some types (__s64 and __u64) that are also defined by () and they conflict). 3. Make dump's reading of the dumpdates file a bit more robust, preventing dump from crashing when the dumpdates file has been modified by hand. 4. Fixed some offset calculations in dump code which could lead to "bread lseek errors" on large filesystems. Thanks to Bruce Lowekamp for reporting this bug and debugging the issue. 5. Made dump use the blkid library when searching for devices by label or uuid instead of dump's own routines. 6. Corrected a bug in dump where a wrong LABEL=... line in /etc/fstab could prevent dump from dumping unrelated filesystems. Thanks to Bruce Lowekamp for reporting the bug. Changes between versions 0.4b35 and 0.4b36 (released April 21, 2004) ==================================================================== 1. Fixed dump compilation with old gcc versions. Thanks to Mike Castle for the patch. 2. Fixed some warnings (howmany, roundup, powerof2 redefined) when compiling against a recent glibc version. 3. Fixed a bug in restore preventing the read of a dump tape written with Solaris 7 ufsdump. Thanks to Patrick Higgins for reporting the bug and providing the test case. 4. Changed dump to enable the creation of volumes of different sizes in a single run (make -B accept a list of values). Patch contributed by Florian Zumbiehl . 5. Use the glibc provided minor() and major() macros instead of our own bitmask implementation. This should be safe for when the major/minor namespace will migrate to 32 bits. Thanks to Zhang Jun for reporting the bug. 6. Made explicit in the dump man page that dump will not create a remote file, it will only write to an already existing one. 7. Another try at making size estimates better again. 8. Put back the inconditional running of the end-of-tape script which was changed in 0.434 to be run only when -M or multiple -f were NOT specified. Some users rely on this feature even when it is combined with -M/-f. 9. Fixed restore when restoring huge backups (where rstdir... temporary files are over 2GB). Thanks to Raphael Jaffey for reporting this, debugging the issue and making the patch. 10. Made restore understand FreeBSD UFS2 tapes. Thanks to David for submitting the bug and providing a test case. 11. Made dump work with an arbitrary integer level (no more 10 levels only limitation). Thanks to Matthew for the patch. Changes between versions 0.4b34 and 0.4b35 (released December 21, 2003) ======================================================================= 1. Added a note in the dump man page saying that the default blocksize can be 32 if -d is used with a high density argument. Thanks to Antonios Christofides for the patch. 2. Fixed configure to correctly understand CPPFLAGS, CFLAGS, LDFLAGS environment variables. Thanks to Arcady Genkin for reporting the bug. 3. Made -e/-E options of dump accept an unlimited number of inodes to be excluded, rather than a hardcoded maximum. Thanks to Dietrich Rothe for the patch. 4. Updated the autoconf system to 2.50. Forced the -D_BSD_SOURCE and -D_USE_BSD_SIGNAL defines in configure in order to solve 64bit build problems because quad_t is redifined with a different signature. Thanks to Mike Harris for reporting this bug. 5. Made restore build on Solaris, making possible to restore Linux's "enhanced" tapes. Thanks to Uwe Gohlke for the patch. 6. Made an extension in the dump tape format capable of saving MacOSX specific inode extensions. Uwe Gohlke wrote the extension and contributed the restore code back into this codebase. The same extension mechanism will be used in the future to save ACLs... 7. Made rmt work correctly with regard to QFA and local/remote files and tapes. The remote access will however work only when the dump provided rmt version is used. If you want to use another rmt server, please do not use the QFA feature. Thanks to Uwe Gohlke for the patch. Changes between versions 0.4b33 and 0.4b34 (released April 18, 2003) ==================================================================== 1. Fixed the INSTALL file to reflect the actual install paths. Thanks to David Ronis for reporting the bug. 2. Fixed the configure script to only check for headers presence instead of trying to compile them. This should fix issues with old build environments. Thanks to Kari Lempiainen for reporting the bug. 3. Fixed restore to correctly ignore sockets when comparing a dump (as socket cannot be properly restored anyway). Thanks to Gunther Reiszig for reporting the bug. 4. Fixed restore to correctly access the archive file (-A argument) even when using a remote tape. Thanks to Fabrice Bellet for reporting the bug. 5. Fixed (again) handling of long (largefile) seeks in rmt. Thanks to Fabrice Bellet for reporting the bug. 6. Fixed restore corner case when dealing with large block sizes dump is able to write now (-b 1024). Thanks to Fabrice Bellet for reporting the bug. 7. Fixed a bug preventing dump to access a filesystem having a label exactly 16 bytes in length. Thanks to for reporting the bug. 8. Made dump store dump dates using explicit timezones, fixing a problem with incremental dumps if the timezone is modified between the dumps. Thanks to Philippe Troin for the bug report and the patch. 9. Fixed a bug encountered when dumping individual files (not full filesystems or directories) and dangling symbolic links happen to be in the list of files. For as far as dump is concerned, dangling symbolic links are allowed, and are dumped as is. Thanks to Jin-su Ahn for reporting the bug and providing the fix. 10. Fixed open and creation modes and permissions for QFA and table-of-contents files in dump and restore. Thanks to Philippe Troin for the patch. 11. Fixed the archive file descriptor handling enabling it to be 0. This can happen in some cases when shell redirections are used. Thanks to Philippe Troin for the patch. 12. Delayed the opening of archive file until after suid had been dropped (fixing a possible security issue if dump is suid). Thanks to Philippe Troin for the patch. 13. Fixed the 'S' command handling in the rmt client part. Thanks to Philippe Troin for the patch. 14. Modified the end-of-tape script handling to print out statistics (and stop the timer) before launching the eot script. Also, the eot script does not get run anymore when using -M (which makes sense) or when multiple tapes are listed on the command line (-f tape0,tape1,tapen) (which also makes sense). Thanks to Philippe Troin for the patch. 15. Relicensed dump/restore under the 'revised' BSD license, as per ftp://ftp.cs.berkeley.edu/ucb/4bsd/README.Impt.License.Change. 16. Added LZO compression to dump. This new compression method has the advantage of being super fast, thus not killing tape streaming on slow machines. Thanks to Helmut Jarausch for the patch and to Markus Oberhumer for giving special permission to include his miniLZO project (GPL licensed) in dump/restore. 17. Some small buffer overruns fixes in rmt. Thanks to Antonomasia for reporting the bugs. 18. Added a special rmt version which can do encryption when writing to tape. Read examples/encrypted_rmt/README for details on how to enable and configure it. Thanks to Ken Lalonde for the patch. 19. Made dump work with 2.5 kernel end of tape early warning semantics. Thanks to Kai Makisara for the patch. 20. Fixed a bug which caused dump -w|-W not to work anymore, because the fs_freq and fs_passno fields in /etc/mtab are always set to 0 0. Thanks to Trent Piepho for reporting the bug. Changes between versions 0.4b32 and 0.4b33 (released February 10, 2003) ======================================================================= 1. Added a note in the restore man page clarifying the question 'set the permissions on the current directory ?' asked by restore at the end of treatment in -i and -x modes. 2. Fixed the endianess issues when reading compressed tapes. Thanks to Dark Force for reporting this bug and providing test cases. 3. Fixed the "ACL won't be dumped" warning message (which showed an extra, unrelated error message). Thanks to Dragan Krnic for reporting this bug. 4. Made dump look first into /etc/mtab, then into /etc/fstab when searching for filesystem paths. Also fixed some problems caused by binding mounts or multiple block device mounts. Thanks to Matus Uhlar , Elliott Mitchell , Greg Edwards , Brian Hoy . (fixes Debian bugs #147086 and #160305, Sourceforge bugs #618699 and #679832). 5. Made dump's -I option accept the value '0' meaning all the read errors will be ignored. This can be useful when running dump from unattended sessions (like cron jobs). Thanks to John I Wang for the suggestion. 6. Fixed the output of dump to indicate 'blocks' instead of 'tape blocks' in the various messages (blocks are always 1 Kilobyte, tape blocks are 1 BK * '-b' argument), and made it clearly print the current blocksize at the start of a dump. Thanks to Michal Szymanski for the suggestions. 7. Made rmt understand long (largefiles) seeks. 8. Fixed build with very old versions of libext2fs, where EXT2_FT_* constants were undefined. 9. Made dump accept the dumpdates path on the command line (-D file option) instead of using only the hardcoded one. Thanks to Piete Brooks for the suggestion. 10. Enabled rmt, LFS, readline, QFA options by default in ./configure. Updated the configure process (new versions of config.guess, config.sub etc). Changes between versions 0.4b31 and 0.4b32 (released November 15, 2002) ======================================================================= 1. Changed dump to use fcntl(F_SETLK) style locking instead of flock() when locking the dumpdates file. With the old locking scheme, a local user having read rights on the dumpdates file could be able to do a Denial of Service attack on dump. In order to lock the dumpdates file with the new scheme, the user would need to have write access on the file. Thanks to Richard Johnson for reporting the bug (originally a bugtraq post). 2. Fixed interactive 'ls' which caused spurious errors warnings about 'undefined filetypes' detected. Thanks to Jorgen Ostling for reporting this bug. 3. Fixed dump's estimate when dealing with sparse inodes. 4. Modified dump to allow setting a blocksize bigger than 32kB (raised the limit to 1024kB), because newer hardware needs this for proper operation. Thanks to Dirk Traenapp for reporting this. 5. Fixed a bug causing Dump to stop and report an error if an inode number in the exclude file was followed by some amount of whitespace. Thanks to Jeffrey Sofferin for reporting this bug. 6. Fixed a bug which caused restore, in some particular cases, to ask some 'scary' questions and leave a bunch of RSTTMP directories behind when restoring incremental tapes. Thanks to Philippe Troin for reporting this bug and providing the test cases. 7. Changed the wording when inodes are excluded from dump: replaced 'Added inode 7 to exclude list' with 'Excluding inode 7 (resize inode) from dump', as suggested by Elliott Mitchell in a Debian bug report. Changes between versions 0.4b30 and 0.4b31 (released July 30, 2002) =================================================================== 1. Fixed rmt open flags transmission (GNU's symbolic syntax over rmt) which I broke in 0.4b29. Thanks to Eros Albertazzi for reporting the bug. Changes between versions 0.4b29 and 0.4b30 (released July 25, 2002) =================================================================== 1. Made dump print out the ext2 logical block number in case of a read error, which can be given as an argument to debugfs' ncheck command, in order to find out the affected inode. Added note about this usage in dump's man page. 2. Fixed a problem in restore when reading tapes written on big endian machines with very old versions of dump. The patch was contributed by George Helffrich . 3. Fixed the tape length calculation when using large tapes and compression. Thanks to Georg Lippold for reporting the bug. 4. Added a new set of examples in dump_on_cd_2 directory, based on dump_on_cd examples but somewhat enhanced, supporting DVD media, and localized in english and german. Thanks to Georg Lippold for the new scripts. 5. Made dump save 32 bit UID/GID. Internally, this was achieved by switching from the old BSD inode format to the new BSD inode format, which means that the tape format was changed. However, since all restore versions out there should transparently support both inode formats, the change should have no side effects. Thanks to John Yu for reporting the bug. 6. Fixed a lot of warnings in the code shown when compiling with 'gcc -W'. Thanks to Matthias Andree for reporting this. 7. Fixed a small markup bug in the dump man page. Thanks to Eric S. Raymond for submitting the patch. 8. Rewrote entirely the man pages using the tmac.an macro package (Linux man page format) instead of the original BSD format. They should be now cleaner and easier to modify. Changes between versions 0.4b28 and 0.4b29 (released June 8, 2002) ================================================================== 1. Fixed a problem in the rmt ioctl command, where ioctl's issued from non Linux clients were misinterpreted. The description of the problem (incompatible numbering in Linux mtio opcodes) is documented at ftp://ftp.fokus.gmd.de/pub/unix/star/README.mtio . Thanks to Jrg Schilling for reporting this bug and providing an excellent, cross-platform replacement for rmt in his star package. 2. Fixed a bug reported by Andy Mentges which caused restore to fail when the inode maps were not entirely contained on the first volume (when using really small volumes or when dumping a huge number of inodes). 3. Fixed a problem in dump, where files in subdirectories of directories that have the nodump flag set (or being excluded with -e/-E) were sometimes incorrectly dumped (instead of being excluded). The original fix is from David C Lawrence in the FreeBSD version of dump: http://www.FreeBSD.org/cgi/query-pr.cgi?pr=32414 Thanks to Ted Grzesik for reporting the bug and help testing the patch. 4. Added some example scripts from Gerd Bavendiek which makes one able to pipe the output of dump, by the net, to a remote CD-burner server. 5. Made dump use O_CREAT|O_TRUNC both locally and remotely (over rmt), and use GNU's symbolic syntax over rmt instead of numerical values to assure multiple platform compatibility. 6. Documented the -d option in restore. 7. Added a -v (verbose) mode to dump. For now it just prints the number of the inode being dumped, but this could evolve in future versions to include interesting debugging output. 8. Added a -o flag to restore, which automatically restores the current directory permissions in -i or -x mode, without asking the operator whether to do so. Patch submitted by Tony Clayton and Peter Samuel . Changes between versions 0.4b27 and 0.4b28 (released April 12, 2002) ==================================================================== 1. Fixed a bug in the QFA feature which could have caused a bad tape positionning on restore (causing extra delays in restore). Credits go to Uwe Gohlke . 2. Added a small note in the dump man page specifying that there should be no white space between the option letter and the -j or -z parameter, thanks to Kenneth Porter 3. Made restore work with older versions of the readline library, by checking in configure for several extended symbols. Restore can now be compiled with a readline as old as the 2.0 release (though it may be a good idea to upgrade it to a more recent version...). Thanks to Andrew Donkin for reporting the build failures. 4. Fixed a performance problem with the QFA file creation in dump, which made unnecessary seeks on the tape slowing down the dump. Thanks to Andrew Donkin for reporting this issue. 5. Removed the inclusion of some kernel headers in the dump source, which prevented the compile in some kernel/glibc headers/architecture combination. Thanks to Bdale Garbee for reporting the bug. 6. Added the appropriate error message when dump fails to open the output file for writing. Thanks to Amith Varghese for reporting this bug. 7. Made restore able to understand large Solaris ufsdump tapes (containing inodes bigger than 4194304). Sun have introduced an "extension" to the dump tape format when dealing with those inodes, which was uncorrectly handled by Linux restore. Thanks to Uwe Gohlke for reporting the bug and providing a test case. 8. Added the -m parameter to dump which optimises the output for inodes having been changed but not modified since the last dump ('changed' and 'modified' have the meaning defined in stat(2)). For those inodes, dump will save only the metadata, instead of saving the entire inode contents. Inodes which are either directories or have been modified since the last dump are saved in a regular way. Uses of this flag must be consistent, meaning that either every dump in an incremental dump set have the flag, or no one has it. Changes between versions 0.4b26 and 0.4b27 (released February 15, 2002) ======================================================================= 1. Fixed behaviour of dump when exceeding resource limits (SIGXFSZ treatment). 2. Added the -L flag to restore to allow the user to specify a maximal allowed number of miscompares when using restore with the -C option to check the backup. 3. Detailed the manual entry for the -N option of restore. 4. Added the -a flag to restore to make able doing unattended restores in -i or -x mode (automatically walks through the multiple dump volumes). 5. Extended the QFA mode to work with local files and/or remote tapes and files. This way, restore can know in advance the tape number and the offset for the inodes to extract and can minimize the extraction time by seeking directly to the good tape/offset. 6. Added the -A option to both dump and restore, which makes dump to archive a dump table-of-contents in the specified file to be used by restore to determine whether a file is in the dump file that is being restored. (the archive file syntax is also compatible with the Solaris ufsdump generated one). 7. Small fix in restore making it able to read some (broken ?) Solaris ufsdump tapes. 8. Fixed dump to correctly recognise the root filesystem when using ext2 disk labels (LABEL=/). Thanks to John Yu for reporting this bug. 9. Added the -P option to restore to create a Quick File Access file from an already made dump. Patch contributed by Uwe Gohlke . 10. Made restore compile and run on Solaris, making it a possible replacement for the standard ufsrestore. Port was contributed by Uwe Gohlke . Changes between versions 0.4b25 and 0.4b26 (released January 7, 2002) ===================================================================== 1. Added a set of backup scripts from Eugenio Diaz in the examples section. It features automatic (cron based) full and incremental dumping of several filesystems on a separate filesystem. 2. Fixed a off-by-one miscalculation which disabled dumping a one letter subdirectory. Thanks to Chris Siebenmann for reporting the bug. 3. Fixed several restore bugs occuring when trying to restore some missing files on the tape. Thanks to Chris Siebenmann for reporting the bug. 4. Fixed --with-ldopts configure argument passing, installing from a separate object directory, makefile cleanups contributed by . 5. Fix a bug which could caused, in some conditions, the highest number inode of a filesystem, to not be dumped. Many thanks to Chris Siebenmann for helping me chase this bug. Changes between versions 0.4b24 and 0.4b25 (released November 17, 2001) ======================================================================= 1. Added a mini howto from Patrick Walsh in the examples directory. 2. Minor man pages syntax corrections. Thanks to Chris Danis for reporting the bugs. 3. Added a script from David B. Peterson to the examples section. It features dumping several filesystems to a remote tape drive upon ssh. 4. Added a patch provided by Richard Jones which allows BRADEMAX (number of read errors tolerated by dump) to be adjusted using the -I option. 5. Fixed a bug which disabled doing "restore -C -f -". Thanks to Clemens Stiglechner for the patch. 6. Add the -l option to restore to specify if, when doing a remote restore, the file used to access the backup is a regular file (the defaults being a tape drive). Restore needs to know this information when reading a remote compressed dump. Previously, this information was autodetected, but the autodetection code fails (with ioctl: Inappropriate ioctl for device) when using a non Linux remote box. Thanks to many users and especially to Eros Albertazzi for reporting this. 7. Found a workaroung for the dump deadlock problem (3 childs stuck in pause(), father in read()). The workaround seems to work for me and several beta-testers. If it doesn't work for you, please report back. 8. Updated the RPM spec file (BuildPrereq, URL etc). Changes between versions 0.4b23 and 0.4b24 (released September 12, 2001) ======================================================================== 1. Fixed the permissions of a newly created QFA file by dump. 2. Cleaned up the source of dump (the external variables definition was a complete mess, making possible to have objects overlap). 3. Fixed restore to use the full tape volume path when doing a compare (since it changes the working directory to the filesystem being compared in the process). 4. Added the -q option to dump which makes dump abort whenever it needs operator attention. It should be easier to use dump in scripts with this option. 5. Detect the use of incompatible options to dump and refuse them (like -a and -B options together). 6. Added bzip2 compression to dump/restore (use option -j level to select it). Note that you will need a restore version >= 0.4b24 in order to restore a bzip2 compressed dump. The same warning as for the zlib compression applies: the tape format of a bzip2 dump is not compatible with the original BSD tape format. 7. Fixed a overflow problem in dump corrupting the dump when very large files were encountered. Thanks to Vladimir Nadvornik for the bug report. 8. Added a ioctl(BLKFLSBUF) in dump which should flush the kernel buffer/page cache before starting the dump, helping a bit those who use dump on mounted filesystems. Thanks to John Yu and to Theodore T'so for this suggestion. 9. Updated the RPM spec file following the RedHat changes (dynamically linked binaries now in /usr/sbin etc). 10. Added a patch from Helmut Jarausch which enables restore to recognise multi volume compressed dumps done on CD. Included his scripts for dump (which pipe the dump output directly into cdrecord) and restore. There is now possible to to backups to CD on the fly! Changes between versions 0.4b22 and 0.4b23 (released July 20, 2001) =================================================================== 1. Fixed a buffer overflow in restore/tape.c. Patch provided by Marcus Meissner (Caldera International Security Dept.). 2. Implement the Sun rmt extended protocol. Patch submitted by Ian Gordon . 3. Check for the e2fsprogs header instead of the linux kernel header. This ensures that dump always has the latest version of this file. Patch submitted by Andreas Dilger . 4. Report any filesystem present in either /etc/fstab with a positive passno or /etc/dumpdates in dump -w output. Patch submitted by Andreas Dilger . 5. Fixed the looping problem in dump introduced in the previous version. 6. Changed the -B option of dump to limit the size of _compressed_ output per volume if compression is on. Patch contributed by Helmut Jarausch . Note however that, since it is impossible to predict the size of the compressed data before doing the compression, the -B limit is a bit conservative. 7. Fixed a bug in reading the operator typed file/tape path for the next volume in restore. 8. Implemented a "-F script" option to restore which permits the user to specify a script which will be launched at the beginning of each tape, useful for automatic programming of tape changers for example. See the restore man page for the script parameters and return codes. 9. Small fix for the QFA routines provided by Uwe Gohlke , and some recommendations for QFA uses in the man pages. 10. Fixed the multivolume restoring where making a mistake to the 'Mount next tape' prompt caused several blocks to be lost. 11. Enhanced the -e option of dump to take as a parameter a comma separated list of inode numbers. 12. Added the -E option to dump which specify a file containing inode numbers to exclude from the dump. 13. Fixed the compressed multi-volume dump + restore. Changes between versions 0.4b21 and 0.4b22 (released May 12, 2001) ================================================================== 1. Made dump report the number of blocks dumped per volume. Thanks to Kenneth Porter for the suggestion. 2. Fix a bug in dump where waiting too much at the 'change volumes' question caused the volume to be rewritten. Thanks to Graham Reed for reporting the bug and providing a patch. 3. Added a compression option to dump, contributed by Jerry Peters . WARNING: the compression works only on files/pipes and drives supporting variable block size. WARNING2: tapes created using the compression feature are incompatible with the standard dump tape format, and a version of restore >= 0.4b22 will be needed for extraction. 4. Fixed some compilation problems for glibc 2.2.2 and 64 bit architectures. Thanks to Paul Slootman for the patch and to Bdale Garbee for forwarding it upstream. 5. Many cleanups (CPP defines, const char warnings, check of ext2fs COMPAT flags, time_t cleanups, added libext2 version in dump usage text) by Andreas Dilger . 6. Made --prefix option work in configure. All the install path are now based on the configure parameters. 7. Added the Quick File Access mode in dump/restore, contributed by Uwe Gohlke . In this mode, dump stores in a file tape position for each inode, and this file is used by restore (if called with parameter Q and the filename) to directly position the tape at the file restore is currently working on. This saves hours when restoring single files from large backups, saves the tapes and the drive's head. Use --enable-qfa option of configure to compile in the QFA support. 8. Added the possibility to dump several files and directories in a single invocation of dump. Thanks to Uwe Gohlke for implementing this option. 9. Fixed the dumping and restoring of files with holes (files ending with holes didn't get dumped or restored correctly). 10. Fixed a socket descriptor leak in dump, which leaved opened 3 file descriptors per dump process (and there is one dump process per tape). 11. Fixed dump large file system support, by explicit use of open64/lseek64/etc functions (explicit use needed because e2fsprogs libraries don't behave well when compiled with FILE_OFFSET_BITS=64). Changes between versions 0.4b20 and 0.4b21 (released January 13, 2001) ====================================================================== 1. Fixed some bugs in the dump -w|-W logic introduced by the previous version. Thanks to Andreas Dilger for his help on this one. 2. Fixed again a compilation problem when using old e2fs headers (filesystem label related). Thanks to many users who reported this stupid error. 3. Fixed a build problem on old lib5 based systems dealing with _PATH_MNTTAB being undefined. Thanks to John Adams for reporting the bug. 4. Improved the error detection in restore when creating the temporary files in TMPDIR. Now restore will corectly report a 'no space left on device' error instead of strange errors which could imply an archive corruption. Thanks to Gabriel Somlo and bgjenero for reporting the bug. 5. Added the throughput information in dump's progression messages. Thanks to Andreas Dilger for the patch. 6. Use libext2fs's inode scanning routines, which are particularly robust when dealing with errors (especially when having some bad blocks on the filesystem). Many thanks to Colin for reporting the bug, investigating the issues, finding a workaround, writing the patch and fully testing it... (of course, if this patch will break anything, he is to blame for :-)). 7. Made dump and restore LFS aware. Dump can dump a filesystem containing large files, generate a large file on output and restore can restore them. This feature is not enabled by default, use --enable-largefile option of configure to enable it (you need to have a LFS aware glibc though). Thanks to Andrea Arcangeli for submitting the patch, and to Theodore T'so for his always useful thoughts. 8. Made dump ask upon a tape write error if it should rewrite the current volume (assume this is a bad tape) or if it should assume an end-of-tape condition (useful for tape drives which behaves badly at the end of the tape). Thanks to Andreas Dilger for the suggestion. Changes between versions 0.4b19 and 0.4b20 (released November 10, 2000) ======================================================================= 1. Fixed a small compilation problem due to a change in the definintion of the struct sigaction in glibc 2.0 / libc5. Thanks to Gunther Schlegel for reporting the bug and to Dave Platt for suggesting a fix. 2. Modified the label and uuid analysis in order to be self-contained (independant of kernel/libc headers). This should fix the compile with older kernel/libc headers and will preserve the functionality. Thanks to Bernhard Erdmann for reporting the bug. 3. The 'exclude inode' option, if applied to a directory inode, excludes now correctly all the leaves of this directory. Thanks to John R. Dennison for reporting the bug. 4. Fixed the '-e' option to disable the possibility to exclude the root inode (which causes the dumps to be unreadable by restore). Prevented array overflow when multiple -e options are used. 5. Fixed dump to correctly interpret a filesystem argument which is a mountpoint and it is not an absolute path (as specified in the fstab). Thanks to Bernhard R. Erdmann for reporting the bug. 6. Made dump able to backup files larger than 2 GB. Note that dump still doesn't cope with files larger than 4 GB. 7. Restore the real uid and gid before invoking an external RSH program (big hole when dump or restore is suid root!). 8. Get the values for the default tape device and the location of fstab file from the system headers. Thanks to Andreas Dilger for the patch. 9. Made dump -w|-W report all recognized filesystems present in either /etc/fstab or /etc/dumpdates, and present the list in the same order as in fstab file. Thanks to Andreas Dilger for the patch. 10. Made dump's -a (automatic end of tape detection) the default. Specifying one of -B, -c, -d or -s options will override the EOM detection. Thanks to Andreas Dilger for the patch. 11. Save the ext2 filesystem label into the dump volume label. Specifying a volume label on the command line (-L option) will override this feature. Thanks to Andreas Dilger for the patch. Changes between versions 0.4b18 and 0.4b19 (released August 20, 2000) ===================================================================== 1. Fixed the signal handling in dump (which I broke in 0.4b17) which was causing several strange dump failures (dump hanged or segmentation faults etc). 2. Specified the default blocksize in the dump man page. 3. Changed two info messages of restore to be written on stdout instead of stderr in order to leave stderr only for errors or warnings. Thanks to Stephen Atwell for the suggestion. 4. Corrected an off by one calculation which prevented dumping a directory having a 1 character name length. Thanks to Bernhard Erdmann for reporting the bug. 5. Reinforce dump in order to allow only level 0 and no -u option when dumping a subdirectory, and document this in the man page. Thanks to Bernhard Erdmann for reporting the bug. 6. Fixed a small harmless bug in restore which caused in some conditions hard links to be restored several times (therefore generation some warning messages). Thanks to Kenneth Porter for reporting the bug. 7. Updated the RPM spec file to the latest RedHat version, providing FHS packaging and other cosmetic changes. You will need RPM version >= 3.0.5 in order to build the RPM. 8. Updated the configure script to check for libtermcap before checking for libreadline, because we need this library in order to compile the readline support. 9. Made dump understand the LABEL= and UUID= notation both in /etc/fstab and on the command line. Note that you will need the /proc filesystem in order to use these notations. Thanks to Erik Troan for providing the patch. Changes between versions 0.4b17 and 0.4b18 (released June 30, 2000) =================================================================== 1. Fixed a potential buffer overflow in restore. Thanks to Stan Bubrouski for reporting the bug. 2. Fixed a readline-related bug which prevented 'cat DUMPFILE | restore -i -f -' from working. Thanks to Charles Karney for the bug report. 3. Changed a few "panic" into "exit", causing restore to be more stable against some attacks (like the last one reported on Bugtraq, although the last version of restore was not vulnerable - just dumped core). Thanks to Andreas Hasenack for reporting the bugs to me. 4. Removed the suid-root bit on dump and restore in the default build (and generated RPMs). It should be safer now. Users who need the suid-root capabilities in order to make network backups should read first the man page of dump and enable the suid bit manually. 5. Added -ltermcap to the compile parameters for restore when using readline support, in order to make the compile process work on some systems (SuSE ?). Thanks to Patrik Schindler for reporting the bug. Changes between versions 0.4b16 and 0.4b17 (released June 1st, 2000) ==================================================================== 1. The -F script is called now *only* at the end of a tape, not at the end of the dump. Thanks to Christian Haul for the bug report. Normally, the device name and the current volume number are passed on the command line of the script. However, if you want the old style script (with no arguments passed on the command line), you can enable it in configure with the --enable-oldstylefscript. 2. Use posix signal handling to preserve dump functionality with libc5. Thanks to Jeff Johnson for the patch. 3. Made the exit code of restore in case of a 'C'ompare command reflect the result of the compare. An exit status of 0 means the dump archive is correct, 1 means tape errors, 2 means that some files were modified. Thanks to Kenneth Porter for the suggestion. 4. Made (finally) quotes work in interactive restore. 5. Small fixes in order to allow dump to compile with a really old e2fsprogs version. Thanks to Ian Zimmerman for the bug report. 6. Add GNU readline capabilities to interactive restore. Use configure's --enable-readline flag to enable this feature. Thanks to Patrik Schindler for the suggestion. 7. Do the compare on the fly in restore 'C' mode (this will allow not to exhaust the available /tmp space when ccmparing large files). Thanks to Kenneth Porter for the suggestion. Changes between versions 0.4b15 and 0.4b16 (released March 11, 2000) ==================================================================== 1. Fixed some several duplicate 'DUMP: DUMP:' in the output of dump. 2. Corrected the estimation of blocks to dump. Note that this is still wrong for large directory inodes, due to the size of a BSD directory entry on the tape (estimation is based on the size of the ext2 directory, which is smaller because it doesn't contain the null character at the end). 3. Made dump report the total number of MB written to tape at the end of run. Thanks to W. Reilly Cooley for the patch. 4. Added the -X option to restore giving the possibility to read the names of the files to be extracted/listed from a text file (in addition of the command line). Thanks to Dejan Muhamedagic for the patch. 5. Added the device name and the current volume number as arguments to the end of tape script (dump -F option). 6. Made the multi-volume dump work again (after having broken it in 0.4b15). Changes between versions 0.4b14 and 0.4b15 (released March 2, 2000) =================================================================== 1. Added a prompt command in interactive restore mode. Thanks to Andreas Dilger for the patch. 2. Fixed a buffer overflow problem in dump (caused by not checking the size of the filesystem parameter). Thanks to Kim Yong-jun for reporting this on Bugtraq (and to several dump users who forwarded me his mail). 3. Added the '-F script' option to dump in order to launch a script at the end of each tape (to be used with a tape changer, or to notify the sysadmin by pager etc.). 4. Fixed a bug in restore compare code caused by the changes I made in 0.4b14. 5. Fixed the treatment of options using the old BSD syntax in both dump and restore. Changes between versions 0.4b13 and 0.4b14 (released February 10, 2000) ======================================================================= 1. Fixed a bug in dump which may have caused invalid deleted directories to be dumped out if they were deleted after the mapping pass. This could occure on active filesystem and lead to heap corruption (causing dump malfunction in many possible ways). Thanks to Jan Sanislo for finding this bug and submitting the patch. 2. Fixed the handling of the filesystem parameter in dump. A '/mnt/disk' parameter caused the disk contents to be dumped, but a '/mnt/disk/' parameter caused the mountpoint directory to be dumped (generally an empty directory). 3. Improved the output of dump in order to tell which directory it is currently dumping (when dumping a subtree). 4. Added the '-e' exclude inode option to dump. Thanks to Isaac Chuang for contributing with the patch. 5. Added a REPORTING-BUGS file in order to provide a guide on how to correctly report a bug in dump/restore. 6. Fixed a restore problem when restoring a hard link to an inode having the immutable or append-only attribute set. Thanks to Ambrose Li for submitting the patch. 7. Fixed a compatibility problem between dumps made on little endian machines (the format was correct) and big endian machines (the format was incorrect). This fix break the compatibility with the older dumps made on big endian machines (sparc, m86k, ppc etc). For the first time in linux dump's history (I believe), the dumps made by *BSD, Linux/alpha, Linux/sparc and Linux/x86 are compatible, so interchangeable. Thanks to Rob Cermak for submitting the bug and helping me test the fix. 8. Fixed the way dump reports the remaining percent/time, if the number of blocks actually dumped exceeds the estimated number of blocks. Thanks to Jean-Paul van der Jagt for reporting the bug. Changes between versions 0.4b12 and 0.4b13 (released January 21, 2000) ====================================================================== 1. Small Y2K fix in the man pages :). Thanks to Bernhard Sadlowski for reporting the bug. 2. Removed the requirement to build the RPM as root from the spec file. Thanks to Christian Weisgerber for submitting this. 3. Fixed a bug in dump related to the 'filetype' feature of ext2fs, causing dump to block when dumping really huge filesystems. Many thanks to Patrik Schindler for helping me find this bug. 4. Fixed the treatment for an interrupt signal when dump access the remote tape through RSH. Thanks to Christian Weisgerber for providing the patch. 5. Fixed a bug which was causing dump/restore to display garbage characters instead of the remote host name. Changes between versions 0.4b11 and 0.4b12 (released January 8, 2000) ===================================================================== 1. Small fix in the dump man page. Thanks to Thorsten Kukuk for submitting the patch. 2. Fix for the exit code when using the size estimate option of dump. Thanks to Matti Taskinen for submitting the patch. 3. Handle EINTR in atomical reads/writes in dump, which was causing dump to fail on some systems. Thanks to Eric Jergensen for reporting the bug and submitting the patch. 4. Handle more than 16 characters for the device names in dumpdates. (up to 255 now). Thanks to Rainer Clasen for tracking down the problem and proposing the solution. 5. Fixed a bug in dump which prevented the creation of the dumpdates file when doing a 0-level dump without already having a dumpdates file. Thanks to Patrik Schindler for reporting the bug. 6. Changed the way dump 'S' flag reports the size estimate from number of blocks into bytes (making it compatible with the Solaris version, and simplifying things for amanda users). Thanks to Jason L Tibbitts III for reporting the bug. 7. Fixed a compatibility problem in linux/alpha dump tape format. Now the linux/alpha dump are (again) compatible with the other dump formats. But this breaks compatibility with older dumps made on alpha. Thanks to Mike Tibor for helping me in finding this bug. Changes between versions 0.4b10 and 0.4b11 (released December 5, 1999) ====================================================================== 1. Added a '--enable-kerberos' to configure. 2. Added a 'S' option to dump which determines the amount of space that is needed to perform the dump without actually doing it, similar to the Sun's ufsdump 'S' option. Patch contributed by Rob Cermak . 3. Added a 'M' multi-volume option to dump and restore which enables dumping to multiple files (useful when dumping to an ext2 partition to make several dump files in order to bypass the 2GB file size limitation). The 'f' argument is treated as a prefix and the output files will be named 001, 002 etc. With the 'M' flag, restore automatically selects the right file without asking to enter a new tape each time. 4. Fixed a memory leak which was causing dump to grow very big (270MB when dumping a 10GB filesystem...). Thanks to Jason Fearon for reporting the bug. Changes between versions 0.4b9 and 0.4b10 (released November 21, 1999) ====================================================================== 1. Make configure test if the system glob routines support extended syntax (ALTDIRFUNC). If not, use the internal glob routines instead of system ones. Thanks to Bernhard Sadlowski for reporting the bug and helping me resolve this and other minor libc5 compiling glitches. 2. Fix a problem when dumping a ext2fs with the 'filetype' feature enabled. Thanks to Patrick J. LoPresti for reporting the bug and to Theodore Y. Ts'o for providing the patch. 3. Made the nodump flag work on directories. A directory which has the nodump flag gets never dumped, regardless of its contents. 4. Integrate a patch from Jeremy Fitzhardinge which allows dump on an active ext3 filesystem. However, this is a "quick and dirty" patch which enables backup of an ext3 filesystem through the ext2 compatibility (by ignoring the NEEDS_RECOVERY bit). The journal file is not recognized and it is dumped (it should not). 5. Test the superblock compatibility flags when dumping, in order to be sure that we know how to deal with specific features. Changes between versions 0.4b8 and 0.4b9 (released November 5, 1999) ==================================================================== 1. Use lchown instead of chown, fixing a possible security problem when restoring symlinks (a malicious user could use this to deliberately corrupt the ownership of important system files). Thanks to Chris Siebenmann for detecting this and providing the patch. Changes between versions 0.4b7 and 0.4b8 (released November 3, 1999) ==================================================================== 1. Put dump sources under CVS, added Id tags in all files so one can use 'ident' on binary files. 2. Added the dump/restore version in the usage text so one can easily verify the version he is using. 3. Small patch from Nuno Oliveira which fixes a va_start/va_end problem on linux-ppc (always call va_start va_end in pairs each time we use a vararg function). 4. Added again the DT_* constants because old libc does not contain them :(. Thanks to Eric Maisonobe for submitting the bug report. 5. Use ext2fs_llseek instead of llseek. With recent e2fsprogs this should enable dumping big (huge) filesystems. 6. Added the RSH environment variable in order to be able to use a rsh replacement like ssh when doing remote backups (and bypass the security limitations of rcmd). Now you can do remote backups without being root (or making dump setuid root). 7. Modified again the way dumpdates works. For incremental dumps, we need to read dumpdates even if we are not using 'u' option. Thanks to Bdale Garbee for his ideas on how this should work. Changes between versions 0.4b6 and 0.4b7 (released October 8, 1999) =================================================================== 1. Removed the 'k' flag from the restore 'about' text if kerberos was not compiled in. 2. Prototyped (f)setflags from e2fsprogs and corrected the calls to them (fsetflags takes a char*, setflags an open fd!). 3. (f)setflags is called only if the flags aren't empty. If the file is a special file, a warning is printed, because changing flags implies opening the device. Normally, a special file should not have any flag... (Debian bug #29775, patch provided by Abhijit Dasgupta ). 4. Made possible to dump a file system not mentioned in /etc/fstab. (Debian bug #11904, patch provided by Eirik Fuller ). 5. Changed the default behaviour to not create dumpdates unless 'u' option is specified. Removed the old "debian-patch" which provided the same thing. (Debian bug #38136, #33818). 6. Removed all those dump*announce, since they were getting old... 7. Added warning messages if dumpdates does not exist and when an inferior level dump does not exist (except for a level 0 dump). 8. Debugged the glob calls in interactive mode: restore used a dirent struct which was different from the /usr/include/dirent.h one (this used to work, is it a glibc2 change?), so none of the compat glob (which used /usr/include/dirent.h) or the system glob worked. Restore use now the system dirent (and the system DT_* constants), which are compatible with BSD ones. 9. Added a configure flag (--with-dumpdatespath) to specify the location of dumpdates file. By default, it is /etc/dumpdates. 10. Added the "AUTHOR" and "AVAILABILITY" sections and included the current date/version in man pages. 11. Corrected the estimation of remaining time when the operator doesn't change the tapes quickly enough. This was an old bug, I thought I corrected it, and discovered that in fact it was corrected in two different places, so the results canceled each other... Changes between versions 0.4b5 and 0.4b6 (released October 1, 1999) =================================================================== 1. Integrated multiple patches from RedHat, Debian and SuSE: - tweak dump/itime.c to not try to read dumpdates if the 'u' option isn't specified. - several fixes in the man pages. - update the default tape device to /dev/st0. - many updates for Linux Alpha (byte ordering, size_t etc). - buffer overruns. - use environment variable for TMPDIR (instead of /tmp). - use sigjmp_buf instead of jmp_buf (RedHat bug #3260). - workaround egcs bug (RedHat bugs #4281 and #2989). - wire $(OPT) throughout Makefile's. 2. Upgrade the dump revision to 1, making possible to dump filesystems made with e2fsprogs-1.15 or newer. Nothing seems to break... 3. Fix some compile warnings, prototype all functions. 4. Use glibc err/glob instead of internal compatibility routines (only if available). 5. Fix a compile error on Linux 2.2.7 / libc5 (5.4.44) (patch provided by Bernhard Sadlowski ). Changes between versions 0.4b4 and 0.4b5 (released September 22, 1999) ====================================================================== 1. Integrated the changes from FreeBSD-3.1-RELEASE (mostly bug fixes, buffer overruns, dump has now an "automatic tape length calculation" flag, dump/restore can use kerberos now (this is NOT tested), use environment variables for TAPE and RMT etc.). 2. Integrated three RedHat patches ("glibc", "kernel" and "bread" patches) 3. Corrected a bug in restore when using 'C' option with multi-volumes tapes (files splited accros two tapes give "size changed" errors when comparing). 4. Corrected the long standing bug when dumping multiple tapes. This works for me, needs further testing. Changes between versions 0.4b3 and 0.4b4 (released January 17, 1997) ==================================================================== 1. Dump now runs correctly on kernels 2.1.x Fix made by Gerald Peters Changes between versions 0.4b2 and 0.4b3 ======================================== 1. Use realpath() if available 2. Report statistics Changes between versions 0.4b1 and 0.4b2 ======================================== 1. Fixed the bug fix from Greg Lutz (I had made a mistake when integrating the patch) 2. Fixed restore to make it able to read FreeBSD 2.x dumps again 3. Fixed configure.in to correctly handle --enable-rmt Changes between versions 0.3 and 0.4b1 ====================================== 1. Integrated the changes from 4.4BSD-Lite2 2. Integrated the patches from Debian and Red Hat 3. Portability changes: use the __u32, __u16, __s32, and __s16 types 4. Changed dump to use the Ext2fs library to get block addresses. This should solve the endianness problem on SparcLinux. 5. Created a configure.in file (shamelessly stolen from the e2fsprogs distribution's one) to use autoconf 6. Fixed a few minor bugs Changes between versions 0.2e and 0.2f ====================================== 1. Added the creation of named pipes (fifos) in restore. 2. Added the -N flag in the restore manual page. 3. Added the file kernel.patch which contains the llseek() optimization patch for 1.2.x kernels. 4. Fixed a bug in the restoration of symbolic links: owner and group were not restored. 5. Integrated some changes from FreeBSD 2.2. 6. Added a call to ftruncate() after restoring each file to restore correctly files ending by a hole. Changes between versions 0.2d and 0.2e ====================================== 1. Fixed a bug in the "set owner/mode" process. Every file was restored with owner = root (0) and group = root/wheel/whatever (0). Changes between versions 0.2c and 0.2d ====================================== 1. Dump is now able to backup 2GB+ filesystems. 2. Dump and restore can now be linked as static binaries. Changes between versions 0.2b and 0.2c ====================================== 1. Fixed a bug when dumping ``slow'' (i.e. normal) symbolic links. Changes between versions 0.2a and 0.2b ====================================== 1. Really fixed the bug that I should have corrected in 0.2a. 2. Enabled optimization again. Changes between versions 0.2 and 0.2a ===================================== 1. Disabled the optimization during compilation. Changes between versions 0.1 and 0.2 ==================================== 1. Fixed a bug in fstab.c which caused a null pointer to be stored in the fs_type field (actually, I modified the file fstab.c to make it use the mntent functions). 2. Dump and restore now use a 4.3 BSD compatible dump format. Backups made by dump should be readable by the BSD restore and backups made by the BSD dump should be readable by restore. Unfortunately, this means that the dump format has changed between version 0.1 and version 0.2 :-( 3. Dump is now able to backup a subtree, it is no longer limited to whole filesystems like the BSD version. 4. Dump now uses ext2_llseek() so it is able to backup filesystems bigger than 2 GB. Changes between versions 0.0 and 0.1 ==================================== 1. Now create links rdump and rrestore during the `make install' step. 2. Linux port specific bugs added to the manual pages 3. Incorrect estimation of the number of tapes blocks fixed when doing incremental backups. 4. Better ls-like format in restore in interactive mode. dump-0.4b46/m4/0000755002013200001440000000000012763343254010157 500000000000000dump-0.4b46/m4/libtool.m40000644002013200001440000112570012763342427012014 00000000000000# libtool.m4 - Configure libtool for the host system. -*-Autoconf-*- # # Copyright (C) 1996-2001, 2003-2015 Free Software Foundation, Inc. # Written by Gordon Matzigkeit, 1996 # # This file is free software; the Free Software Foundation gives # unlimited permission to copy and/or distribute it, with or without # modifications, as long as this notice is preserved. m4_define([_LT_COPYING], [dnl # Copyright (C) 2014 Free Software Foundation, Inc. # This is free software; see the source for copying conditions.

All responses are in .B ASCII and in one of the following two forms. .PP Successful commands have responses of: .RS .B A\fInumber\fR\en .RE .PP where .I number is an .B ASCII representation of a decimal number. .PP Unsuccessful commands are responded to with: .RS .B E\fIerror-number\fR\en\fIerror-message\fR\en .RE .PP where .I error-number is one of the possible error numbers described in .BR intro (2) and .I error-message is the corresponding error string as printed from a call to .BR perror (3). .PP The protocol is comprised of the following commands, which are sent as indicated - no spaces are supplied between the command and its arguments, or between its arguments, and \en indicates that a newline should be supplied: .TP .B O\fIdevice\fR\en\fImode\fR\en Open the specified .I device using the indicated .IR mode . .I Device is a full pathname and .I mode is an .B ASCII representation of a decimal number suitable for passing to .BR open (2). If a device had already been opened, it is closed before a new open is performed. .TP .B C\fIdevice\fR\en Close the currently open device. The .I device specified is ignored. .TP .B L\fIwhence\fR\en\fIoffset\fR\en Perform an .BR lseek (2) operation using the specified parameters. The response value is that returned from the .B lseek call. .TP .B W\fIcount\fR\en Write data onto the open device. .B Rmt reads .I count bytes from the connection, aborting if a premature end-of-file is encountered. The response value is that returned from the .BR write (2) call. .TP .B R\fIcount\fR\en Read .I count bytes of data from the open device. If .I count exceeds the size of the data buffer (10 kilobytes), it is truncated to the data buffer size. .B Rmt then performs the requested .BR read (2) and responds with .B A\fIcount-read\fR\en if the read was successful; otherwise an error in the standard format is returned. If the read was successful, the data read is then sent. .TP .B I\fIoperation\fR\en\fIcount\fR\en Perform a .B MTIOCOP .BR ioctl (2) command using the specified parameters. The parameters are interpreted as the .B ASCII representations of the decimal values to place in the .B mt_op and .B mt_count fields of the structure used in the .B ioctl call. The return value is the .I count parameter when the operation is successful. .IP By issuing the .B I-1\en0\en command, a client will specify that he is using the VERSION 1 protocol. .IP For a VERSION 0 client, the .I operation parameter is the platform .B mt_op value (could be different if the client and the .B rmt server are on two different platforms). For a VERSION 1 client, the .I operation parameter is standardized as below: .RS .TP .B 0 Issue a .B MTWEOF command (write .I count end-of-file records). .TP .B 1 Issue a .B MTFSF command (forward space over .I count file marks). .TP .B 2 Issue a .B MTBSF command (backward space over .I count file marks). .TP .B 3 Issue a .B MTFSR command (forward space .I count inter-record gaps). .TP .B 4 Issue a .B MTBSR command (backward space .I count inter-record gaps). .TP .B 5 Issue a .B MTREW command (rewind). .TP .B 6 Issue a .B MTOFFL command (rewind and put the drive offline). .TP .B 7 Issue a .B MTNOP command (no operation, set status only). .RE .TP .B i\fIoperation\fR\en\fIcount\fR\en Perform an extended .B MTIOCOP .BR ioctl (2) command using the specified parameters. The parameters are interpreted as the .B ASCII representations of the decimal values to place in the .B mt_op and .B mt_count fields of the structure used in the .B ioctl call. The return value is the .I count parameter when the operation is successful. The possible operations are: .RS .TP .B 0 Issue a .B MTCACHE command (switch cache on). .TP .B 1 Issue a .B MTNOCACHE command (switch cache off). .TP .B 2 Issue a .B MTRETEN command (retension the tape). .TP .B 3 Issue a .B MTERASE command (erase the entire tape). .TP .B 4 Issue a .B MTEOM command (position to end of media). .TP .B 5 Issue a .B MTNBSF command (backward space count files to BOF). .RE .TP .B S Return the status of the open device, as obtained with a .B MTIOCGET .B ioctl call. If the operation was successful, an \*(lqack\*(rq is sent with the size of the status buffer, then the status buffer is sent (in binary, which is non-portable between different platforms). .TP .BI s sub-command This is a replacement for the previous .B S command, portable across different platforms. If the open device is a magnetic tape, return members of the magnetic tape status structure, as obtained with a .B MTIOCGET ioctl call. If the open device is not a magnetic tape, an error is returned. If the .B MTIOCGET operation was successful, the numerical value of the structure member is returned in decimal. The following sub commands are supported: .RS .TP .B T return the content of the structure member .B mt_type which contains the type of the magnetic tape device. .TP .B D return the content of the structure member .B mt_dsreg which contains the "drive status register". .TP .B E return the content of the structure member .B mt_erreg which contains the "error register". This structure member must be retrieved first because it is cleared after each .B MTIOCGET ioctl call. .TP .B R return the content of the structure member .B mt_resid which contains the residual count of the last I/O. .TP .B F return the content of the structure member .B mt_fileno which contains the file number of the current tape position. .TP .B B return the content of the structure member .B mt_blkno which contains the block number of the current tape position. .TP .B f return the content of the structure member .B mt_flags which contains MTF_ flags from the driver. .TP .B b return the content of the structure member .B mt_bf which contains the optimum blocking factor. .RE .PP Any other command causes .B rmt to exit. .SH DIAGNOSTICS All responses are of the form described above. .SH SEE ALSO .BR rcmd (3), .BR rexec (3), .I /usr/include/sys/mtio.h, .BR rdump (8), .BR rrestore (8) .SH BUGS People should be discouraged from using this for a remote file access protocol. .SH AUTHOR The .B dump/restore backup suit was ported to Linux's Second Extended File System by Remy Card .

This is pretty annoying, since # it makes $ac_aux_dir quite unusable in subdirectories: in the top # source directory, any form will work fine, but in subdirectories a # relative path needs to be adjusted first. # # $ac_aux_dir/missing # fails when called from a subdirectory if $ac_aux_dir is relative # $top_srcdir/$ac_aux_dir/missing # fails if $ac_aux_dir is absolute, # fails when called from a subdirectory in a VPATH build with # a relative $ac_aux_dir # # The reason of the latter failure is that $top_srcdir and $ac_aux_dir # are both prefixed by $srcdir. In an in-source build this is usually # harmless because $srcdir is '.', but things will broke when you # start a VPATH build or use an absolute $srcdir. # # So we could use something similar to $top_srcdir/$ac_aux_dir/missing, # iff we strip the leading $srcdir from $ac_aux_dir.

These files are copied to the given disk, tape or other storage medium for safe keeping (see the .B \-f option below for doing remote backups). A dump that is larger than the output medium is broken into multiple volumes. On most media the size is determined by writing until an end-of-media indication is returned. .PP On media that cannot reliably return an end-of-media indication (such as some cartridge tape drives), each volume is of a fixed size; the actual size is determined by specifying cartridge media, or via the tape size, density and/or block count options below. By default, the same output file name is used for each volume after prompting the operator to change media. .PP .I files-to-dump is either a mountpoint of a filesystem or a list of files and directories to be backed up as a subset of a filesystem. In the former case, either the path to a mounted filesystem or the device of an unmounted filesystem can be used. In the latter case, certain restrictions are placed on the backup: .B \-u is not allowed, the only dump level that is supported is .B 0 and all the files and directories must reside on the same filesystem. .SH OPTIONS The following options are supported by .B dump: .TP .BI \-level# The dump level (any integer). A level 0, full backup, specified by .B \-0 guarantees the entire file system is copied (but see also the .B \-h option below). A level number above 0, incremental backup, tells .B dump to copy all files new or modified since the last dump of a lower level. The default level is 0. Historically only levels 0 to 9 were usable in dump, this version is able to understand any integer as a dump level. .TP .BI \-a \*(lqauto-size\*(rq. Bypass all tape length calculations, and write until an end-of-media indication is returned. This works best for most modern tape drives, and is the default. Use of this option is particularly recommended when appending to an existing tape, or using a tape drive with hardware compression (where you can never be sure about the compression ratio). .TP .BI \-A " archive_file" Archive a dump table-of-contents in the specified .I archive_file to be used by .BR restore (8) to determine whether a file is in the dump file that is being restored. .TP .BI \-b " blocksize" The number of kilobytes per dump record. The default blocksize is 10, unless the .B \-d option has been used to specify a tape density of 6250BPI or more, in which case the default blocksize is 32. Th maximal value is 1024. Note however that, since the IO system slices all requests into chunks of .B MAXBSIZE (which can be as low as 64kB), you can experience problems with .BR dump (8) and .BR restore (8) when using a higher value, depending on your kernel and/or libC versions. .TP .BI \-B " records" The number of 1 kB blocks per volume. Not normally required, as .B dump can detect end-of-media. When the specified size is reached, .B dump waits for you to change the volume. This option overrides the calculation of tape size based on length and density. If compression is on this limits the size of the compressed output per volume. Multiple values may be given as a single argument separated by commas. Each value will be used for one dump volume in the order listed; if .B dump creates more volumes than the number of values given, the last value will be used for the remaining volumes. This is useful for filling up already partially filled media (and then continuing with full size volumes on empty media) or mixing media of different sizes. .TP .BI \-c Change the defaults for use with a cartridge tape drive, with a density of 8000 bpi, and a length of 1700 feet. Specifying a cartridge drive overrides the end-of-media detection. .TP .BI \-d " density" Set tape density to .IR density . The default is 1600BPI. Specifying a tape density overrides the end-of-media detection. .TP .BI \-D " file" Set the path name of the file storing the information about the previous full and incremental dumps. The default location is .IR __DUMPDATES__ . .TP .BI \-e " inodes" Exclude .I inodes from the dump. The .I inodes parameter is a comma separated list of inode numbers (you can use .BR stat (1) to find the inode number for a file or directory). .TP .BI \-E " file" Read list of inodes to be excluded from the dump from the text file .IR file . The file .I file should be an ordinary file containing inode numbers separated by newlines. .TP .BI \-f " file" Write the backup to .IR file ; .I file may be a special device file like .I /dev/st0 (a tape drive), .I /dev/rsd1c (a floppy disk drive), an ordinary file, or .I \- (the standard output). Multiple file names may be given as a single argument separated by commas. Each file will be used for one dump volume in the order listed; if the dump requires more volumes than the number of names given, the last file name will used for all remaining volumes after prompting for media changes. If the name of the file is of the form .I host:file or .I user@host:file .B dump writes to the named file on the remote host (which should already exist, dump doesn't create a new remote file) using .BR rmt (8). The default path name of the remote .BR rmt (8) program is .IR /etc/rmt ; this can be overridden by the environment variable .BR RMT . .TP .BI \-F " script" Run script at the end of each tape (except for the last one). The device name and the current volume number are passed on the command line. The script must return 0 if .B dump should continue without asking the user to change the tape, 1 if .B dump should continue but ask the user to change the tape. Any other exit code will cause .B dump to abort. For security reasons, .B dump reverts back to the real user ID and the real group ID before running the script. .TP .BI \-h " level" Honor the user .B nodump flag .B UF_NODUMP only for dumps at or above the given .IR level . The default honor level is 1, so that incremental backups omit such files but full backups retain them. .TP .BI \-I " nr errors" By default, .B dump will ignore the first 32 read errors on the file system before asking for operator intervention. You can change this using this flag to any value. This is useful when running .B dump on an active filesystem where read errors simply indicate an inconsistency between the mapping and dumping passes. .IP A value of 0 means that all read errors will be ignored. .TP .BI \-j "compression level" Compress every block to be written on the tape using bzlib library. This option will work only when dumping to a file or pipe or, when dumping to a tape drive, if the tape drive is capable of writing variable length blocks. You will need at least the 0.4b24 version of .B restore in order to extract compressed tapes. Tapes written using compression will not be compatible with the BSD tape format. The (optional) parameter specifies the compression level bzlib will use. The default compression level is 2. If the optional parameter is specified, there should be no white space between the option letter and the parameter. .TP .BI \-k Use Kerberos authentication to talk to remote tape servers. (Only available if this option was enabled when .B dump was compiled.) .TP .BI \-L " label" The user-supplied text string .I label is placed into the dump header, where tools like .BR restore (8) and .BR file (8) can access it. Note that this label is limited to be at most .B LBLSIZE (currently 16) characters, which must include the terminating \e0. .TP .BI \-m If this flag is specified, .B dump will optimise the output for inodes having been changed but not modified since the last dump ('changed' and 'modified' have the meaning defined in .BR stat (2) ). For those inodes, .B dump will save only the metadata, instead of saving the entire inode contents. Inodes which are either directories or have been modified since the last dump are saved in a regular way. Uses of this flag must be consistent, meaning that either every dump in an incremental dump set have the flag, or no one has it. .IP If you use this option, be aware that many programs that unpack files from archives (e.g. tar, rpm, unzip, dpkg) may set files' mtimes to dates in the past. Files installed in this way may not be dumped correctly using "dump -m" if the modified mtime is earlier than the previous level dump. .IP Tapes written using such 'metadata only' inodes will not be compatible with the BSD tape format or older versions of .B restore. .TP .BI \-M Enable the multi-volume feature. The name specified with .B f is treated as a prefix and .B dump writes in sequence to .I 001, 002 etc. This can be useful when dumping to files on an ext2/3/4 partition, in order to bypass the 2GB file size limitation. .TP .BI \-n Whenever .B dump requires operator attention, notify all operators in the group .B operator by means similar to a .BR wall (1). .TP .BI \-q Make .B dump abort immediately whenever operator attention is required, without prompting in case of write errors, tape changes etc. .TP .BI \-Q " file" Enable the Quick File Access support. Tape positions for each inode are stored into the file .I file which is used by .B restore (if called with parameter .B \-Q and the filename) to directly position the tape at the file .B restore is currently working on. This saves hours when restoring single files from large backups, saves the tapes and the drive's head. .IP It is recommended to set up the st driver to return logical tape positions rather than physical before calling .B dump/restore with parameter .BR \-Q . Since not all tape devices support physical tape positions those tape devices return an error during .B dump/restore when the st driver is set to the default physical setting. Please see the .BR st (4) man page, option .B MTSETDRVBUFFER , or the .BR mt (1) man page, on how to set the driver to return logical tape positions. .IP Before calling .B restore with parameter .BR \-Q , always make sure the st driver is set to return the same type of tape position used during the call to .BR dump . Otherwise .B restore may be confused. .IP This option can be used when dumping to local tapes (see above) or to local files. .TP .BI \-s " feet" Attempt to calculate the amount of tape needed at a particular density. If this amount is exceeded, .B dump prompts for a new tape. It is recommended to be a bit conservative on this option. The default tape length is 2300 feet. Specifying the tape size overrides end-of-media detection. .TP .BI \-S Size estimate. Determine the amount of space that is needed to perform the dump without actually doing it, and display the estimated number of bytes it will take. This is useful with incremental dumps to determine how many volumes of media will be needed. .TP .BI \-T " date" Use the specified date as the starting time for the dump instead of the time determined from looking in .I __DUMPDATES__ . The format of .I date is the same as that of .BR ctime (3) followed by an rfc822 timezone specification: either a plus or minus sign followed by two digits for the number of hours and two digits for the minutes. For example, -0800 for eight hours west of Greenwich or +0230 for two hours and a half east of Greenwich. This timezone offset takes into account daylight savings time (if applicable to the timezone): UTC offsets when daylight savings time is in effect will be different than offsets when daylight savings time is not in effect. For backward compatibility, if no timezone is specified, a local time is assumed. This option is useful for automated dump scripts that wish to dump over a specific period of time. The .B \-T option is mutually exclusive from the .B \-u option. .TP .BI \-u Update the file .I __DUMPDATES__ after a successful dump. The format of .I __DUMPDATES__ is readable by people, consisting of one free format record per line: filesystem name, increment level and .BR ctime (3) format dump date followed by a rfc822 timezone specification (see the .B \-u option for details). If no timezone offset is specified, times are interpreted as local. Whenever the file is written, all dates in the file are converted to the local time zone, without changing the UTC times. There may be only one entry per filesystem at each level. The file .I __DUMPDATES__ may be edited to change any of the fields, if necessary. .TP .BI \-v The .B \-v (verbose) makes .B dump to print extra information which could be helpful in debug sessions. .TP .BI \-W .B Dump tells the operator what file systems need to be dumped. This information is gleaned from the files .I __DUMPDATES__ and .IR /etc/fstab . The .B \-W option causes .B dump to print out, for all file systems in .I __DUMPDATES__ , and recognized file systems in .I /etc/mtab and .IR /etc/fstab . the most recent dump date and level, and highlights those that should be dumped. If the .B \-W option is set, all other options are ignored, and .B dump exits immediately. .TP .BI \-w Is like .BR \-W , but prints only recognized filesystems in .I /etc/mtab and .I /etc/fstab which need to be dumped. .TP .BI \-y Compress every block to be written to the tape using the lzo library. This doesn't compress as well as the zlib library but it's much faster. This option will work only when dumping to a file or pipe or, when dumping to a tape drive, if the tape drive is capable of writing variable length blocks. You will need at least the 0.4b34 version of .B restore in order to extract compressed tapes. Tapes written using compression will not be compatible with the BSD tape format. .TP .BI \-z "compression level" Compress every block to be written on the tape using zlib library. This option will work only when dumping to a file or pipe or, when dumping to a tape drive, if the tape drive is capable of writing variable length blocks. You will need at least the 0.4b22 version of .B restore in order to extract compressed tapes. Tapes written using compression will not be compatible with the BSD tape format. The (optional) parameter specifies the compression level zlib will use. The default compression level is 2. If the optional parameter is specified, there should be no white space between the option letter and the parameter. .PP .B Dump requires operator intervention on these conditions: end of tape, end of dump, tape write error, tape open error or disk read error (if there is more than a threshold of nr errors). In addition to alerting all operators implied by the .B \-n key, .B dump interacts with the operator on dump's control terminal at times when .B dump can no longer proceed, or if something is grossly wrong. All questions .B dump poses .I must be answered by typing \*(lqyes\*(rq or \*(lqno\*(rq, appropriately. .PP Since making a dump involves a lot of time and effort for full dumps, .B dump checkpoints itself at the start of each tape volume. If writing that volume fails for some reason, .B dump will, with operator permission, restart itself from the checkpoint after the old tape has been rewound and removed, and a new tape has been mounted. .PP .B Dump tells the operator what is going on at periodic intervals, including usually low estimates of the number of blocks to write, the number of tapes it will take, the time to completion, and the time to the tape change. The output is verbose, so that others know that the terminal controlling .B dump is busy, and will be for some time. .PP In the event of a catastrophic disk event, the time required to restore all the necessary backup tapes or files to disk can be kept to a minimum by staggering the incremental dumps. An efficient method of staggering incremental dumps to minimize the number of tapes follows: .IP \(em Always start with a level 0 backup, for example: .RS 14 .B /sbin/dump -0u -f /dev/st0 /usr/src .RE .IP This should be done at set intervals, say once a month or once every two months, and on a set of fresh tapes that is saved forever. .IP \(em After a level 0, dumps of active file systems are taken on a daily basis, with this sequence of dump levels: .RS 14 .B 3 2 5 4 7 6 9 8 9 9 ... .RE .IP For the daily dumps, it should be possible to use a fixed number of tapes for each day, used on a weekly basis. Each week, a level 1 dump is taken, and the daily Hanoi sequence repeats beginning with 3. For weekly dumps, another fixed set of tapes per dumped file system is used, also on a cyclical basis. .PP After several months or so, the daily and weekly tapes should get rotated out of the dump cycle and fresh tapes brought in. .PP Another backup strategy is the Tower of Hanoi sequence, which reuses older tapes in a way that for newer dates the available restore points are more frequent, then for older dates (see http://en.wikipedia.org/wiki/Backup_rotation_scheme for additional information). .PP (The 4.3BSD option syntax is implemented for backward compatibility but is not documented here.) .SH ENVIRONMENT .TP .B TAPE If no .B \-f option was specified, .B dump will use the device specified via .B TAPE as the dump device. .B TAPE may be of the form .IR tapename , .IR host:tapename , or .IR user@host:tapename . .TP .B RMT The environment variable .B RMT will be used to determine the pathname of the remote .BR rmt (8) program. .TP .B RSH .B Dump uses the contents of this variable to determine the name of the remote shell command to use when doing remote backups (rsh, ssh etc.). If this variable is not set, .BR rcmd (3) will be used, but only root will be able to do remote backups. .SH FILES .TP .I /dev/st0 default tape unit to dump to .TP .I __DUMPDATES__ dump date records .TP .I /etc/fstab dump table: file systems and frequency .TP .I /etc/mtab dump table: mounted file systems .TP .I /etc/group to find group .I operator .SH SEE ALSO .BR fstab (5), .BR restore (8), .BR rmt (8) .SH DIAGNOSTICS Many, and verbose. .SH COMPATIBILITY The format of the .I __DUMPDATES__ file has changed in release 0.4b34, however, the file will be read correctly with either pre-0.4b34 or 0.4b34 and later versions of .B dump provided that the machine on which .B dump is run did not change timezones (which should be a fairly rare occurrence). .SH EXIT STATUS .B Dump exits with zero status on success. Startup errors are indicated with an exit code of 1; abnormal termination is indicated with an exit code of 3. .SH BUGS It might be considered a bug that this version of dump can only handle ext2/3/4 filesystems. Specifically, it does not work with FAT filesystems. .PP Fewer than 32 read errors (change this with .BR \-I ) on the filesystem are ignored. If noticing read errors is important, the output from dump can be parsed to look for lines that contain the text 'read error'. .PP When a read error occurs, .B dump prints out the corresponding physical disk block and sector number and the ext2/3/4 logical block number. It doesn't print out the corresponding file name or even the inode number. The user has to use .BR debugfs (8), commands .B ncheck and .B icheck to translate the .B ext2blk number printed out by .B dump into an inode number, then into a file name. .PP Each reel requires a new process, so parent processes for reels already written just hang around until the entire tape is written. .PP The estimated number of tapes is not correct if compression is on. .PP It would be nice if .B dump knew about the dump sequence, kept track of the tapes scribbled on, told the operator which tape to mount when, and provided more assistance for the operator running .BR restore . .PP .B Dump cannot do remote backups without being run as root, due to its security history. Presently, it works if you set it setuid (like it used to be), but this might constitute a security risk. Note that you can set .B RSH to use a remote shell program instead. .SH AUTHOR The .B dump/restore backup suite was ported to Linux's Second Extended File System by Remy Card .

Configuration is made by running the configure script. Run `configure --help' to get a list of options. After configuring the package, you can type `make' to compile the programs, and `make install' to install the binaries in /usr/local/sbin and the manual pages in `/usr/local/man/man8'. You need to have the latest Ext2fs programs installed on your system since this version of dump uses the Ext2fs library written by Theodore T'so. The Ext2fs programs are included in all Linux distributions (e2fsprogs and e2fsprogs-dev[el] packages), or you can download the most up to date version from http://e2fsprogs.sourceforge.net. dump-0.4b46/MAINTAINERS0000644002013200001440000000073412713003654011250 00000000000000The dump and restore backup suit was ported to Linux's Second Extended File System by Rmy Card He was the maintainer of the initial versions of dump (up and including 0.4b4, released in january 1997). I decided to continue the developpement and release a new version. Rmy didn't respond to any mail I sent to him, so I have promoted myself as the new maintainer :) So, starting with 0.4b5, the new maintainer is me, Stelian Pop . dump-0.4b46/dump.lsm0000644002013200001440000000121312763343254011236 00000000000000Begin3 Title: dump and restore for Ext2fs Version: 0.4b46 Entered-date: 09MAY16 Description: Port of the 4.4BSD dump and restore backup suite Keywords: backup, filesystem, Ext2fs Author: University of California, Berkeley Maintained-by: stelian@popies.net (Stelian Pop) Primary-site: http://dump.sourceforge.net/ 0kB dump-0.4b46.tar.gz 0 dump.lsm Original-site: ftp.freebsd.org /pub/bsd-sources/4.4BSD-Lite2/sbin dump/* restore/* Platforms: linux 2.0.x, linux 2.2.x, linux 2.4.x, linux 2.6.x e2fsprogs 1.14 or better Copying-policy: BSD End dump-0.4b46/compile0000755002013200001440000001624512763342436011146 00000000000000#! /bin/sh # Wrapper for compilers which do not understand '-c -o'. scriptversion=2012-10-14.11; # UTC # Copyright (C) 1999-2013 Free Software Foundation, Inc. # Written by Tom Tromey . # # This program is free software; you can redistribute it and/or modify # it under the terms of the GNU General Public License as published by # the Free Software Foundation; either version 2, or (at your option) # any later version. # # This program is distributed in the hope that it will be useful, # but WITHOUT ANY WARRANTY; without even the implied warranty of # MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

They were ported to Linux by Remy Card , by using the Ext2fs library, written by Theodore Ts'o . Kevin Layer added the comparison code in restore. Doug Paul helped me to make dump able to backup 2GB+ filesystems. David Frey (the old Debian dump maintainer), Bdale Garbee (the new Debian dump maintainer) and the people from Red Hat Software provided lots of patches. Stelian Pop is now the current maintainer (since dump-0.4b5). Thanks to people who reported problems with the port, sent patches, and suggested various improvements.

We avoid this by adding ## dummy dependencies for each header file. Too bad gcc doesn't do ## this for us directly. ## Some versions of gcc put a space before the ':'. On the theory ## that the space means something, we add a space to the output as ## well. hp depmode also adds that space, but also prefixes the VPATH ## to the object.

You just found a bug in dump/restore and want to know what to do next. Here are some guidelines you will want to follow before sending me a mail: 1. Are you sure it's a bug? If you just are not sure about how to use a specific feature of dump, please post your question on the dump-users mailing list. While you are there, try to browse the archives of the mailing list and see if someone asked the same question before. NOTE: questions about how to use the d(ensity) (b)locksize parameters enters this category! 2. Always test the last version of dump/restore before submitting a bug report. Your problem is maybe already fixed! 3. Consult the bugs using the bug system at sourceforge. Use this bug system if you want to report a new bug or contribute to an existing bug. You may want to create an account on sourceforge for that, so the comments will automatically be forwarded to your email address. 4. If you are using the bug system and didn't create an account on sourceforge, put your email address into the bug report! If I am unable to contact you for more information, chances are that the bug will never be solved! 5. Please provide detailed information about your system: - distribution and its version (RedHat, Debian, Suse, homemade etc.) - architecture (Intel, Sparc, PalmPilot etc.) - dump/restore version (0.4b13, etc) - e2fsprogs version (1.17, etc) - libc version (libc5, glibc2.0, gilbc2.1 etc) - complete output of the dump/restore command which caused the failure (ok, you can delete the 'xx% done' lines) - the device you dump into/restore from (tape drive, file etc). - anything else you believe will help me to find the bug... 6. In addition, if you want to report a bug on dump, provide also: - details of your filesystem you want to dump: output of the command 'tune2fs -l /dev/sda1' (replace sda1 with your partition...) - if your filesystem was mounted when doing the dump, try to rerun the command with the filesystem unmounted. Does the bug still occur? - try to dump your filesystem using /dev/null as tape device. This may help to know that the bug is not triggered by a buggy device or tape or remote access problems. Ok, here are the pointers you may want to access: Dump latest release: http://sourceforge.net/project/filelist.php?group_id=1306 Dump mailing lists: http://sourceforge.net/mail/?group_id=1306 Dump bug system: http://sourceforge.net/bugs/?group_id=1306 My email: stelian@popies.net dump-0.4b46/ChangeLog0000644002013200001440000000003312713003654011315 00000000000000See NEWS for more details. dump-0.4b46/compat/0000755002013200001440000000000012763343254011122 500000000000000dump-0.4b46/compat/lib/0000755002013200001440000000000012763343254011670 500000000000000dump-0.4b46/compat/lib/rmtflags.c0000644002013200001440000001062212725723271013573 00000000000000/* * Ported to Linux's Second Extended File System as part of the * dump and restore backup suit * Remy Card , 1994-1997 * Stelian Pop , 1999-2000 * Stelian Pop - Alcve , 2000-2002 */ /* * Copyright (c) 1983, 1993 * The Regents of the University of California.

A full backup of a file system may be restored and subsequent incremental backups layered on top of it. Single files and directory subtrees may be restored from full or partial backups. .B Restore works across a network; to do this see the .B \-f flag described below. Other arguments to the command are file or directory names specifying the files that are to be restored. Unless the .B \-h flag is specified (see below), the appearance of a directory name refers to the files and (recursively) subdirectories of that directory. .PP Exactly one of the following flags is required: .TP .B \-C This mode allows comparison of files from a dump. .B Restore reads the backup and compares its contents with files present on the disk. It first changes its working directory to the root of the filesystem that was dumped and compares the tape with the files in its new current directory. See also the .B \-L flag described below. .TP .B \-i This mode allows interactive restoration of files from a dump. After reading in the directory information from the dump, .B restore provides a shell like interface that allows the user to move around the directory tree selecting files to be extracted. The available commands are given below; for those commands that require an argument, the default is the current directory. .RS .TP .B add \fR[\fIarg\fR] The current directory or specified argument is added to the list of files to be extracted. If a directory is specified, then it and all its descendants are added to the extraction list (unless the .B \-h flag is specified on the command line). Files that are on the extraction list are prepended with a \*(lq*\*(rq when they are listed by .BR ls . .TP .BI cd " arg" Change the current working directory to the specified argument. .TP .B delete \fR[\fIarg\fR] The current directory or specified argument is deleted from the list of files to be extracted. If a directory is specified, then it and all its descendants are deleted from the extraction list (unless the .B \-h flag is specified on the command line). The most expedient way to extract most of the files from a directory is to add the directory to the extraction list and then delete those files that are not needed. .TP .B extract All files on the extraction list are extracted from the dump. .B Restore will ask which volume the user wishes to mount. The fastest way to extract a few files is to start with the last volume and work towards the first volume. .TP .B help List a summary of the available commands. .TP .B ls \fR[\fIarg\fR] List the current or specified directory. Entries that are directories are appended with a \*(lq/\*(rq. Entries that have been marked for extraction are prepended with a \*(lq*\*(rq. If the verbose flag is set, the inode number of each entry is also listed. .TP .B pwd Print the full pathname of the current working directory. .TP .B quit .B Restore immediately exits, even if the extraction list is not empty. .TP .B setmodes All directories that have been added to the extraction list have their owner, modes, and times set; nothing is extracted from the dump. This is useful for cleaning up after a .B restore has been prematurely aborted. .TP .B verbose The sense of the .B \-v flag is toggled. When set, the verbose flag causes the .B ls command to list the inode numbers of all entries. It also causes .B restore to print out information about each file as it is extracted. .RE .TP .BI \-P " file" .B Restore creates a new Quick File Access file .I file from an existing dump file without restoring its contents. .TP .B \-R .B Restore requests a particular tape of a multi-volume set on which to restart a full restore (see the .B \-r flag below). This is useful if the restore has been interrupted. .TP .B \-r Restore (rebuild) a file system. The target file system should be made pristine with .BR mke2fs (8), mounted, and the user .BR cd 'd into the pristine file system before starting the restoration of the initial level 0 backup. If the level 0 restores successfully, the .B \-r flag may be used to restore any necessary incremental backups on top of the level 0. The .B \-r flag precludes an interactive file extraction and can be detrimental to one's health (not to mention the disk) if not used carefully. An example: .IP .RS 14 .B mke2fs /dev/sda1 .TP .B mount /dev/sda1 /mnt .TP .B cd /mnt .TP .B restore rf /dev/st0 .RE .IP Note that .B restore leaves a file .I restoresymtable in the root directory to pass information between incremental restore passes. This file should be removed when the last incremental has been restored. .IP .BR Restore , in conjunction with .BR mke2fs (8) and .BR dump (8), may be used to modify file system parameters such as size or block size. .TP .B \-t The names of the specified files are listed if they occur on the backup. If no file argument is given, the root directory is listed, which results in the entire content of the backup being listed, unless the .B \-h flag has been specified. Note that the .B \-t flag replaces the function of the old .BR dumpdir (8) program. See also the .B \-X option below. .TP .B \-x The named files are read from the given media. If a named file matches a directory whose contents are on the backup and the .B \-h flag is not specified, the directory is recursively extracted. The owner, modification time, and mode are restored (if possible). If no file argument is given, the root directory is extracted, which results in the entire content of the backup being extracted, unless the .B \-h flag has been specified. See also the .B \-X option below. .SH OPTIONS The following additional options may be specified: .TP .B \-a In .B \-i or .B \-x mode, .B restore does ask the user for the volume number on which the files to be extracted are supposed to be (in order to minimise the time by reading only the interesting volumes). The .B \-a option disables this behaviour and reads all the volumes starting with 1. This option is useful when the operator does not know on which volume the files to be extracted are and/or when he prefers the longer unattended mode rather than the shorter interactive mode. .TP .BI \-A " archive_file" Read the table of contents from .I archive_file instead of the media. This option can be used in combination with the .BR \-t , .BR \-i , or .B \-x options, making it possible to check whether files are on the media without having to mount the media. .TP .BI \-b " blocksize" The number of kilobytes per dump record. If the .B \-b option is not specified, .B restore tries to determine the media block size dynamically. .TP .B \-c Normally, .B restore will try to determine dynamically whether the dump was made from an old (pre-4.4) or new format file system. The .B \-c flag disables this check, and only allows reading a dump in the old format. .TP .B \-d The .B \-d (debug) flag causes .B restore to print debug information. .TP .BI \-D " filesystem" The .B \-D flag allows the user to specify the filesystem name when using .B restore with the .B \-C option to check the backup. .TP .BI \-f " file" Read the backup from .IR file ; .I file may be a special device file like .I /dev/st0 (a tape drive), .I /dev/sda1 (a disk drive), an ordinary file, or .I \- (the standard input). If the name of the file is of the form .I host:file or .IR user@host:file , .B restore reads from the named file on the remote host using .BR rmt (8). .TP .BI \-F " script" Run script at the beginning of each tape. The device name and the current volume number are passed on the command line. The script must return 0 if .B restore should continue without asking the user to change the tape, 1 if .B restore should continue but ask the user to change the tape. Any other exit code will cause .B restore to abort. For security reasons, .B restore reverts back to the real user ID and the real group ID before running the script. .TP .B \-h Extract the actual directory, rather than the files that it references. This prevents hierarchical restoration of complete subtrees from the dump. .TP .BI \-H " hash_size" Use a hashtable having the specified number of entries for storing the directories entries instead of a linked list. This hashtable will considerably speed up inode lookups (visible especially in interactive mode when adding/removing files from the restore list), but at the price of much more memory usage. The default value is 1, meaning no hashtable is used. .TP .B \-k Use Kerberos authentication when contacting the remote tape server. (Only available if this options was enabled when .B restore was compiled.) .TP .B \-l When doing remote restores, assume the remote file is a regular file (instead of a tape device). If you're restoring a remote compressed file, you will need to specify this option or .B restore will fail to access it correctly. .TP .BI \-L " limit" The .B \-L flag allows the user to specify a maximal number of miscompares when using .B restore with the .B \-C option to check the backup. If this limit is reached, .B restore will abort with an error message. A value of 0 (the default value) disables the check. .TP .B \-m Extract by inode numbers rather than by file name. This is useful if only a few files are being extracted, and one wants to avoid regenerating the complete pathname to the file. .TP .B \-M Enables the multi-volume feature (for reading dumps made using the .B \-M option of dump). The name specified with .B \-f is treated as a prefix and .B restore tries to read in sequence from .I 001, 002 etc. .TP .B \-N The .B \-N flag causes .B restore to perform a full execution as requested by one of .BR \-i , .BR \-R , .BR \-r , .B t or .B x command without actually writing any file on disk. .TP .B \-o The .B \-o flag causes .B restore to automatically restore the current directory permissions without asking the operator whether to do so in one of .B \-i or .B \-x modes. .TP .BI \-Q " file" Use the file .I file in order to read tape position as stored using the dump Quick File Access mode, in one of .BR \-i , .B \-x or .B \-t mode. .IP It is recommended to set up the st driver to return logical tape positions rather than physical before calling .B dump/restore with parameter .BR \-Q . Since not all tape devices support physical tape positions those tape devices return an error during .B dump/restore when the st driver is set to the default physical setting. Please see the .BR st (4) man page, option .B MTSETDRVBUFFER , or the .BR mt(1) man page, on how to set the driver to return logical tape positions. .IP Before calling .B restore with parameter .BR \-Q , always make sure the st driver is set to return the same type of tape position used during the call to .BR dump . Otherwise .B restore may be confused. .IP This option can be used when restoring from local or remote tapes (see above) or from local or remote files. .TP .BI \-s " fileno" Read from the specified .I fileno on a multi-file tape. File numbering starts at 1. .TP .BI \-T " directory" The .B \-T flag allows the user to specify a directory to use for the storage of temporary files. The default value is .IR /tmp . This flag is most useful when restoring files after having booted from a floppy. There might be little or no space on the floppy filesystem, but another source of space might exist. .TP .B \-u When creating certain types of files, .B restore may generate a warning diagnostic if they already exist in the target directory. To prevent this, the .B \-u (unlink) flag causes .B restore to remove old entries before attempting to create new ones. .TP .B \-v Normally .B restore does its work silently. The .B \-v (verbose) flag causes it to type the name of each file it treats preceded by its file type. .TP .B \-V Enables reading multi-volume non-tape mediums like CDROMs. .TP .BI \-X " filelist" Read list of files to be listed or extracted from the text file .I filelist in addition to those specified on the command line. This can be used in conjunction with the .B \-t or .B \-x commands. The file .I filelist should contain file names separated by newlines. .I filelist may be an ordinary file or .I - (the standard input). .TP .B \-y Do not ask the user whether to abort the restore in the event of an error. Always try to skip over the bad block(s) and continue. .PP (The 4.3BSD option syntax is implemented for backward compatibility but is not documented here.) .SH DIAGNOSTICS Complains if it gets a read error. If .B y has been specified, or the user responds .BR y , .B restore will attempt to continue the restore. .PP If a backup was made using more than one tape volume, .B restore will notify the user when it is time to mount the next volume. If the .B \-x or .B \-i flag has been specified, .B restore will also ask which volume the user wishes to mount. The fastest way to extract a few files is to start with the last volume, and work towards the first volume. .PP There are numerous consistency checks that can be listed by .BR restore . Most checks are self-explanatory or can \*(lqnever happen\*(rq. Common errors are given below: .TP .I Converting to new file system format A dump tape created from the old file system has been loaded. It is automatically converted to the new file system format. .TP .I : not found on tape The specified file name was listed in the tape directory, but was not found on the tape. This is caused by tape read errors while looking for the file, and from using a dump tape created on an active file system. .TP .I expected next file , got A file that was not listed in the directory showed up. This can occur when using a dump created on an active file system. .TP .I Incremental dump too low When doing an incremental restore, a dump that was written before the previous incremental dump, or that has too low an incremental level has been loaded. .TP .I Incremental dump too high When doing an incremental restore, a dump that does not begin its coverage where the previous incremental dump left off, or that has too high an incremental level has been loaded. .TP .I Tape read error while restoring .TP .I Tape read error while skipping over inode .TP .I Tape read error while trying to resynchronize A tape (or other media) read error has occurred. If a file name is specified, its contents are probably partially wrong. If an inode is being skipped or the tape is trying to resynchronize, no extracted files have been corrupted, though files may not be found on the tape. .TP .I resync restore, skipped blocks After a dump read error, .B restore may have to resynchronize itself. This message lists the number of blocks that were skipped over. .SH EXIT STATUS .B Restore exits with zero status on success. Tape errors are indicated with an exit code of 1. .PP When doing a comparison of files from a dump, an exit code of 2 indicates that some files were modified or deleted since the dump was made. .SH ENVIRONMENT If the following environment variable exists it will be utilized by .BR restore : .TP .B TAPE If no .B \-f option was specified, .B restore will use the device specified via .B TAPE as the dump device. .B TAPE may be of the form .IR tapename , .I host:tapename or .IR user@host:tapename . .TP .B TMPDIR The directory given in .B TMPDIR will be used instead of .I /tmp to store temporary files. .TP .B RMT The environment variable .B RMT will be used to determine the pathname of the remote .BR rmt (8) program. .TP .B RSH .B Restore uses the contents of this variable to determine the name of the remote shell command to use when doing a network restore (rsh, ssh etc.). If this variable is not set, .BR rcmd (3) will be used, but only root will be able to do a network restore. .SH FILES .TP .I /dev/st0 the default tape drive .TP .I /tmp/rstdir* file containing directories on the tape .TP .I /tmp/rstmode* owner, mode, and time stamps for directories .TP .I ./restoresymtable information passed between incremental restores .SH SEE ALSO .BR dump (8), .BR mount (8), .BR mke2fs (8), .BR rmt (8) .SH BUGS .B Restore can get confused when doing incremental restores from dumps that were made on active file systems. .PP A level 0 dump must be done after a full restore. Because .B restore runs in user code, it has no control over inode allocation; thus a full dump must be done to get a new set of directories reflecting the new inode numbering, even though the content of the files is unchanged. .PP The temporary files .I /tmp/rstdir* and .I /tmp/rstmode* are generated with a unique name based on the date of the dump and the process ID (see .BR mktemp (3) ), except when .B \-r or .B \-R is used. Because .B \-R allows you to restart a .B \-r operation that may have been interrupted, the temporary files should be the same across different processes. In all other cases, the files are unique because it is possible to have two different dumps started at the same time, and separate operations shouldn't conflict with each other. .PP To do a network restore, you have to run .B restore as root or use a remote shell replacement (see .B RSH variable). This is due to the previous security history of .B dump and .BR restore . ( .B restore is written to be setuid root, but we are not certain all bugs are gone from the code - run setuid at your own risk.) .PP At the end of restores in .B \-i or .B \-x modes (unless .B \-o option is in use), .B restore will ask the operator whether to set the permissions on the current directory. If the operator confirms this action, the permissions on the directory from where .B restore was launched will be replaced by the permissions on the dumped root inode. Although this behaviour is not really a bug, it has proven itself to be confusing for many users, so it is recommended to answer 'no', unless you're performing a full restore and you do want to restore the permissions on '/'. .PP It should be underlined that because it runs in user code, .B restore , when run with the .B \-C option, sees the files as the kernel presents them, whereas .B dump sees all the files on a given filesystem. In particular, this can cause some confusion when comparing a dumped filesystem a part of which is hidden by a filesystem mounted on top of it. .SH AUTHOR The .B dump/restore backup suite was ported to Linux's Second Extended File System by Remy Card .
