Improve data throughput when using compression in dump by + allowing multiple slaves to compress in parallel. Thanks + to Phillip Susi for the patch. + +2. Add dump encryption support and reorganise the whole + compression/encryption code as plugins. Thanks to + Bear Giles for the patch. + +3. Add sqlite index support and reorganize the QFA code + as plugins. Thanks to Bear Giles for + the patch. + +Changes between versions 0.4b43 and 0.4b44 (released June 10, 2011) +=================================================================== + +1. Recognize ext4 partitions in dump -w commands (Sourceforge + bug #3125587, RedHat bug #658890). Thanks to Jan Görig + for reporting the bug and + submitting the patch. + +2. 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 Görig + 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 Frédéric + Brière 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. @@ -17,6 +282,31 @@ Changes between versions 0.4b37 and 0.4b38 (released ????????????) (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) ==================================================================
