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 . + +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 @@ -37,6 +359,25 @@ Changes between versions 0.4b19 and 0.4b20 (released ???????????????) 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.
