New in v1.1.1 (????/??/??) -------------------------- rdiff-backup now writes SHA1 sums into its mirror_metadata file for all regular files, and checks them when restoring. The above greatly increases the size of the mirror_metadata files, so diff them for space efficiency, as suggested by Dean Gaudet. Added two new comparison modes: full file (using the --compare-full or --compare-full-at-time) or by hash (--compare-hash and --compare-hash-at-time). Applied Alec Berryman's patch to update the no-compression regexp. Alec Berryman's fs_abilities patch is supposed to help with AFS. Fixed filename-too-long crash when quoting. Patched carbonfile support, re-enabled it by default. New in v1.1.0 (2005/10/24) -------------------------- Refactored fs_abilities for more flexibility. In particular, avoid quoting if both source and destination file systems are case-insensitive. Increased buffer sizes by factor of 4, because everyone probably has 4 times as much RAM now as when I originally picked those values. When possible, fsync using a writable file descriptor. This may help with cygwin. (Requested/tested by Dave Kempe.) Support req 104755: Added --preserve-numerical-ids option, which makes rdiff-backup preserve uids/gids instead of unames/gnames. (Suggested by Wiebe Cazemier) Fix for bug #14799 reported by Bob McKay: Crash when backing up files with high permissions (like suid) to some FAT systems. New in v1.0.2 (2005/10/24) -------------------------- Fix for spurious security violation from --create-full-path (reported by Mike Bydalek). Fix for bug 14545 which was introduced in version 1.0.1: Quoting caused a spurious security violation. (Important for Mac OS X) An error reading carbonfile data on Mac OS X should no longer cause a crash. (Thanks to Kevin Horton for testing.) Carbonfile support now defaults to off, even if the system appears to support it. It can be manually enabled with the --carbonfile switch. If you know something about Mac OS X and want to look at the carbonfile code so it can be re-enabled by default, please do so :) (help available from list) New in v1.0.1 (2005/09/10) -------------------------- Fix for "'filetype' of type exceptions.KeyError" error when restoring. Test case provided by Davy Durham. (The problem was the mirror_metadata file could become un-synced when a file is deleted when rdiff-backup is running and later the directory that file is in gets deleted.) Librsync signature blocksize now based on square root of file length. rdiff-backup now writes its PID to current_mirror marker (suggested by Kevin Spicer). fsync_directories defaults to None, to avoid errors in testing (suggestion by Charles Duffy). bug#14209: Security bug with --restrict-read-only and --restrict-update-only allowed file statting and directory listing outside path. Bug with --restrict option allowed writes outside path. (Reported by Charles Duffy.) bug #14304: Python 2.2 compatibility spoiled by device files. lchown no longer required, which is good news for Mac OS X 10.3. New in v1.0.0 (2005/08/14) -------------------------- Handle cases of junk uid/gids better on 64bit systems. (Bug report by Nick Bailey) Filenames in the file_statistics*gz files are now quoted the same way as filenames in the metadata file (LF => \n and \ => \\). Fix from Paul P Komkoff Jr for uid typo in text_to_entrytuple. bug#12726: fix regressing of devices while running as non-root -- zero length files are created as placeholders. bug#13476: must always compare device numbers when we compare inode numbers -- fix a non-fatal problem with hardlinks when a filesystem is moved to another device (and the inodes don't change). bug#13475: correct an UpdateError when backing up hardlinks with EAs and/or ACLs. debian bug#306798: SELinux security attributes can not be removed and rdiff-backup should not fail when it fails to remove them from temp files. fix from Konrad Podloucky. bug#12949: eliminate an exception during fs abilities testing on OS X 10.4. fix from Daniel Westermann-Clark. patch#4136: OSX filename/rsrc has been deprecated for some time, and as of OSX 10.4 it causes log spam. the new proper use is filename/..namedfork/rsrc. fix from Daniel Westermann-Clark. Log EACCES from listxattr rather than raising an exception -- this can happen when the repository has permission problems. Added Keith Edmunds patch adding the --create-full-path option. Fixed selection bug reported by Daniel Richard G. bug#13576: You can now back ACLs to a computer that doesn't have the posix1e module. bug#13613: Fix for overflow error that could happen when backing up files with dates far in the future on a 64bit machine to a 32 bit one. Symlink ownership should be preserved now. Reported by Naoki Takebayashi and others. New in v0.13.6 (2005/04/07) --------------------------- Fixed timezone bug. Hopefully this is the last one. (Thanks to Randall Nortman for bug report.) Added fix for listing/restoring certain bad archives made when there was a timezone bug. (Thanks to Stephen Isard) ************** Serious bug fix ****************** If a directory in the source directory was replaced by certain symlinks, then if later backups failed they could cause files in the directory that the symlink pointed to to be deleted! Much thanks to Alistair Popple for pointing this bug out and providing a test case. New in v0.13.5 (2005/03/28) --------------------------- Added error-correcting fsync suggestion by Antoine Perdaens. rdiff-backup may work better with NFS now. Fix by Dean Gaudet for --calculate-average mode (it broke somewhere in 0.13.x). Fix for regress warning code: rdiff-backup should warn you if you are trying to back up a directory into itself. Fix for restoring certain directories when not run as root. Now when determining group permissions check supplementary groups as well as main group. (Bug report by Ryan Castle.) Fixed bug which could cause crash when backing up 3 or more hard linked files and the first gets deleted during processing. (Thanks to Dean Gaudet for bug report.) Fixed user/group restoring error noticed by Fran Firman. Checked in Robert Shaw's --chars-to-quote patch Treated hard link permission problem on Mac OS X by applying suggestion by David Vasilevsky Dean Gaudet's patch fixes "--restrict /" option. Added Robert Shaw's --exclude-fifo, --include-symbolic-links, etc. options. Added Maximilian Mehnert's fix for too many open files bug. New in v0.13.4 (2004/01/31) --------------------------- Checked in patch by John Goerzen to support Mac OS X Finder information. As John says: > Specifically, it adds storage of: > > * 4-byte creator > * 4-byte type > * integer flags > * dual integer location Much thanks to John for adding this useful feature all by himself! Added --compare and --compare-at-time switches for comparing a directory with the backup information saved about it. Thanks to Erik Forsberg, who noticed that this feature was missing. Regressing and restoring should now take less memory when processing large directories (noticed by Luke Mewburn and others). When regressing, remove mirror_metadata and similar increments first. This will hopefully help regressing a backup that failed because disk was full (reported by Erik Forsberg). Fixed remote quoting errors found by Daniel Drucker. Fixed handling of (lack of) daylight savings time. Earlier bug would cause some files to be marked an hour later. Thanks to Troels Arvin and Farkas Levente for bug report. Altered file selection when restoring so excluded files will not be deleted from the target dir. The old behavior was technically intended and documented but not very convenient. Thanks to Oliver Kaltenecker for bug report. Fixed error when --restrict path given with trailing backslash. Bug report by �ke Br�nnstr�m. Fixed many functions like --list-increments, --remove-older-than, etc. which previously didn't work with filename quoting. Thanks to Vinod Kurup for detailed bug report. New in v0.13.3 (2003/10/14) --------------------------- Fixed some of the --restrict options which would cause spurious violation errors. --list-changed-since and --list-at-time now work remotely. Thanks to Morten Werner Olsen for bug report. Fixed logic bug that could make restoring extremely slow and waste memory. Thanks for Jacques Botha for report. Fixed bug restoring some directories when mirror_metadata file was missing (as when made by 0.10.x version). Regressing and restoring as non-root user now works on directories that contain unreadable files and directories as long as they are owned by that user. Bug report by Arkadiusz Miskiewicz. Hopefully this is the last of the unreadable file bugs... Rewrote hard link tracking system. New way should use less memory. Fixed bug causing rdiff-backup to crash when backing up from system supporting EAs/ACLs to one that didn't. New in v0.13.2 (2003/09/16) --------------------------- Change ownership policy and added --user-mapping-file and --group-mapping-file switches. See man page for more information. Added option --never-drop-acls to cause fatal error instead of dropping any acls or acl entries. Thanks to Greg Freemyer for suggestion. Specified socket type as SOCK_STREAM. (Error reported by Erik Forsberg.) Fixed bug backing up unreadable regular files and directories when rdiff-backup is run by root on the source site and non-root on the destination side. (Reported by Troels Arvin and Arkadiusz Miskiewicz.) If there is data missing from the destination dir (for instance if a user mistakenly deletes it), only warn when restoring, instead of exiting with error. Fixed bug in EA/ACL restoring, noticed by Greg Freemyer. Updated quoting of filenames and extended attributes names to match forthcoming attr/facl utilities. Strange characters should now be properly escaped. Fixed problems with --restrict options that would cause proper sessions to fail. Thanks to Randall Nortman for error report. Added new time specification by backup number. So now you can '--remove-older-than 2B' or '--list-at-time 0B'. Original suggestion by Alan Bailward. File examples.html added to distribution; examples section removed from man page. Removed option --no-change-dir-inc-perms. Instead when copying permissions to directory increments, mask with 0777. New in v0.13.1 (2003/08/08) --------------------------- Restore of archives made by 0.10.x and earlier fixed, although hard link information is not restored unless it is current in the mirror. (Bug reported by Jeff Lessem.) Fixed problem with door files locally when repository is remote. (Reported by Robert Weber.) Patch by Jeffrey Marshall fixes socket/fifo recognition on Mac OS X (which apparently has buggy macros). Patch by Jeffrey Marshall fixes --calculate-average mode, which seems to have broken recently. rdiff-backup should now work and build with python 2.3. Thanks to Arkadiusz Miskiewicz and Arkadiusz Patyk for bug reports and a patch. rdiff-backup now builds and requires librsync 0.9.6. This version should be much better than the old one and everyone should probably upgrade. Much thanks to Donovan Baarda for all the work that went into this release. New in v0.13.0 (2003/07/22) --------------------------- To prevent the buildup of confusing and error-prone options, the capabilities of the source and destination file systems are now autodetected. Detected features include allowed characters, extended attributes, access control lists, hard links, ownership, and directory fsyncing. Options such as --windows-mode, --chars-to-quote, --quoting-char, and --windows-restore-mode have been removed. Now rdiff-backup supports user extended attributes (EAs). To take advantage of this you will need the python module pyxattr and a file system that supports EAs. Thanks to Greg Freemyer for valuable discussion. Support for access control lists (ACLs) was also added. An ACL capable file system and the python package pylibacl (which exports the posix1e module) are required. Thanks to Greg Freemyer for valuable discussion. Thanks to patches by Daniel Hazelbaker, rdiff-backup now reads and writes Mac OS X style resource forks! ****** Warning ****** The above features are new to this development release, and it is difficult to test all the possibly combinations of source and destination file systems. They should not be considered stable. However, help would be appreciated testing these new features. ****** Warning #2 ****** rdiff-backup records ACL and EA information in files designed to be compatible with the utilities "getfacl" and "getfattr". However, there is a possible security hole in both these formats (see http://acl.bestbits.at/pipermail/acl-devel/2003-June/001498.html). rdiff-backup's format will be fixed when getf{attr|acl}'s is. Added --list-increment-sizes switch, which tells you how much space the various backup files take up. (Suggested by Andrew Bressen) Although it should be detected automatically, can avoid copying permissions to directory increments with --no-change-dir-inc-perms. (Problem on FreeBSD when backing up sticky directories reported by Troels Arvin.) Fixed bug with --check-destination and --windows-mode reported by Tucker Sylvestro. The librsync blocksize is now chosen based on filesize. This should make operations on large files faster (in some cases, orders of magnitude faster). Thanks to Ty! Boyack for bringing this issue to my attention. New in v0.12.0 (2003/06/26) --------------------------- Fixed (?) bug that caused crash when file changes type from regular file in middle of download (reported by Ty! Boyack). Failure to construct regular file in regression/restoration only causes warning, not fatal error. Removed --exclude-mirror option. (Probably no one uses this, and it adds clutter.) --include and --exclude options should work now with restores, with some speed penalty. New in v0.11.5 (2003/06/20) --------------------------- Added EDEADLOCK to the list of skippable errors. (Thanks to Dave Kempe for report.) Added --list-at-time option at request of Farkas Levente. Various fixes for backing up onto windows directories. Thanks to Keith Edmunds for bug reports and testing. Fixed possible crash when a file would be deleted while being processed (reported by Robert Weber). Handle better cases when there are two files with the same name in the same directory. Added --windows-restore switch, for use when when restoring from a windows-style file system to a normal one. Use --windows-mode when backing up. Scott Bender's patch fixes backing up hard links when first linked file is quoted. New in v0.11.4 (2003/03/15) --------------------------- Fixed bug incrementing sockets whose filenames were pretty long, but not super long. Reported by Olivier Mueller. Added Albert Chin-A-Young's patch to add a few options to the setup.py install script. Apparently fixed rare utime type bug. Thanks to Christian Skarby for report and testing. Added detailed file_statistics (in addition to session_statistics) as requested by Dean Gaudet. Disable with --no-file-statistics option. Minor speed enhancements. New in v0.11.3 (2003/03/04) --------------------------- Fixed a number of bugs reported by Olivier Mueller: Brought some old parts of the man page up-to-date. Fixed bug if unrecoverable error on second backup to a directory. Fixed spurious error message that could appear after a successful backup. --print-statistics option works again (before it would silently ignored). Fixed cache pipeline overflow bug. This error could appear on large remote backups when many files have not changed. New in v0.11.2 (2003/03/01) --------------------------- Fixed seg fault bug reported by a couple sparc/openbsd users. Thanks to Dave Steinberg for giving me an account on his system for testing. Re-enabled --windows-mode and filename quoting. Fixed selection bug: In 0.11.1, files which were included in one backup would be automatically included in the next. Now you can include/exclude files session-by-session. Fixed ownership compare bug: In 0.11.1, backups where the destination side was not root would preserve ownership information by recording it in the metadata file. However, mere ownership changes would not trigger creation of new increments. This has been fixed. Added the --no-inode-compare switch. You probably don't need to use it though. If a special file cannot be created on the destination side, a 0 length regular file will be written instead as a placeholder. (Restores should work fine because of the metadata file.) Yet another error handling strategy (hopefully this is the last one for a while, because this stuff isn't very exciting, and takes a long time to write): All recoverable errors are classified into one of three groups: ListErrors, UpdateErrors, and SpecialFileErrors. rdiff-backup's reaction to each error is more formally defined (see the error policy page, currently at http://rdiff-backup.stanford.edu/error_policy.html). rdiff-backup makes no attempt to recover or clean up after unrecoverable errors. However, it now uses fsync() to increment the destination directory in a reversable way. If there is an error, the next backup will regress the destination directory into its state before the aborted backup. The above process can be done without a backup with the --check-destination-dir option. Improved error logging. Instead of the old haphazard reporting method, which sometimes didn't indicate the file an error occurred on, now all recoverable errors are reported in a standard format and also written to the error_log.<time>.data file in the rdiff-backup-data directory. Thanks to Dean Gaudet and others for repeatedly bugging me about this. New in v0.11.1 (2002/12/31) --------------------------- **Warning** Various features have been removed from this version, so this is not a safe upgrade. Also this version has less error checking, and, if it crashes, this version may be more prone to leave the destination directory in an inconsistent state. I plan to look at these issues in the next version. Also, this version is quite different from previous ones, so you cannot run version 0.11.1 on one end of a connection and any previous version on the other side. The following features have been removed: --mirror-only option: If you just want to mirror something, use rsync. (Or you could use rdiff-backup and then just delete the rdiff-backup-data directory, and then update the root mtime.) --change-source-perms option: This feature was pretty complicated to implement, and if something happened to rdiff-backup during a transfer, the old permissions could not be restored. All "resume" related functionality, like --checkpoint-interval: This was complicated to implement, and didn't seem to work all that well. Directory statistics file: Although the session statistics file is still generated, the directory statistics file no longer is, because the new code structure makes it less inconvenient. The various --exclude and --include options no longer work when restoring. This may be added later if there is demand. --windows-mode and filename quoting doesn't work. There have been several requests for this in the past, so it will probably be re-added in the next version. Extensive refactoring. A lot of rdiff-backup's code was structured as if it were still in one file, so it didn't make enough use of Python's module system. Now rdiff-backup writes metadata (uid, gid, mtime, etc.) to a compressed text file in the rdiff-backup-data directory. Here are some ramifications: A user does not need root access on the destination side to record file ownership information. Some files may be recognized as not having changed based on this metadata, so it may not be necessary to traverse the whole mirror directory. This can reduce file access on the destination side. Even when the --no-hard-links option is given when backing up, link relationships can be restored properly. However, if this option is given, mirror files will not be linked together. Special file types like device and sockets which cannot be created on the remote side for some reason can still be backed up and restored properly. Fixed bug with the --{include|exclude}-globbing-filelist options (reported by Claus Herwig). Added --list-changed-since option to list the files changed since the given date, and added Bud Bruegger's patch to that. The format and information this option provides will probably change in the near future. Restoring is now pipelined for better high latency performance, and unchanged files in the target directory will not be recopied. New in v0.11.0 (2002/10/05) --------------------------- If get a socket error from trying to create a socket whose name is too long, just skip file instead of exiting with error (bug report by Ivo De Decker). Added --exclude-special-files switch, which excludes fifos, symlinks, sockets, and device files. --windows-mode is now short for --windows-time-format --chars-to-quote A-Z: --no-hard-links --exclude-special-files. Thanks to Paul-Erik T�rr�nen for some helpful windows info. Multiple --include and --exclude statements can now be given in a single file. See the documentation on --{include|exclude}-globbing-filelist. Thanks to Henrik Lewander for pointing out that command line length could otherwise be a problem. Fixed bug in filelist processing that ignored leading or trailing whitespace in filelists. Now filenames with, for instance, trailing spaces can be used in filelists. Filelists which took advantage of this bug for formatting may have to be editted. Applied major/minor patch contributed by David S. rdiff-backup should now correctly copy device files on platforms such as NetBSD. It is now possible to restore from a read-only filesystem (before rdiff-backup would fail when trying to open log file). Thanks to Gregor Zattler for bug report. Fixed bug that prevented certain restores when the source directory was specified with a trailing backslash. Added a bit more logging so it should be apparent which file was being processed when an error occurs (thanks to Gerd Knops for suggestion). Fixed bug when using --chars-to-quote and directory deleted that has quoted characters in it. New in v0.10.1 (2002/09/16) --------------------------- rdiff-backup should now correctly handle files larger than 2GB. Thanks to Russ Allbery for telling me how to do this. New in v0.10.0 (2002/09/10) --------------------------- Fixed bug, probably introduced in 0.9.3, which prevented restores from a local source to a remote destination. Reported by Phillip Eby. Fixed another bug reported by Phillip Eby, where restores would fail if rdiff-backup had only been run once and no increments were available. A few man page additions regarding restoring, statistics, and --test-server (thanks to Gregor Zattler, Christopher Schanzle, and Tobias Polzin for suggestions). Fixed comparison bug where rdiff-backup would unnecessarily report a directory as changed when its source size differed from its mirror size. Thanks to Tim Allen for report. New in v0.9.5 (2002/08/09) -------------------------- Fixed --verbosity option (now both -v and --verbosity work). Thanks to Chris Dumont for report. ****** IMPORTANT ****** Fixed serious permissions bug found by Robert Weber. Previous versions in the 0.9.x branch would throw away high bit permissions (like the setuid and setuid bits). This would be especially bad when running with the --change-source-perms operation. Anyone running 0.9.0 - 0.9.4 should upgrade immediately. Complain about --change-source-perms when running as root, as this option should not be necessary then. Fixed bug with --windows-mode. Thanks to Chris Grindstaff for report. New in v0.9.4 (2002/07/24) -------------------------- Man page now correctly included in rpm. To prevent confusion, rdiff-backup script does not have exec permissions until it is installed (thanks Jason Piterak). Sockets are now replicated. Why not? (Suggestion by Mickey Everts) Bad resuming information (because, say, it is left over from a previous version) should no longer cause exit, except when --resume is specified. Better error handling in certain cases when errors occur in file reads (thanks to John Goerzen for report). New in v0.9.3 (2002/07/15) -------------------------- Added --sleep-ratio option after hearing that rdiff-backup was too hard on hard disks (thanks to Steve Alexander for the suggestion). Quick example: --sleep-ratio 0.25 makes rdiff-backup sleep about 25% of the time. Maybe this will help on bandwidth usage also. Fixed -m/--mirror-only option. Added --exclude-other-filesystems option. Thanks to Paul Wouters for the suggestion. Added convenience field TotalDestinationSizeChange (total change in destination directory - mirror change + increments change) to session_statistics file. Handle a particular situation better where a file changes in a certain way while rdiff-backup is processing it. Before rdiff-backup would just crash; now it skips the file. Thanks to Scott Bender for the bug report. A couple interface fixes to --remove-older-than. Added some security features to the protocol, so rdiff-backup will now only allow commands from remote connections. The extra security will be enabled automatically on the client (it knows what to expect), but the extra switches --restrict, --restrict-update-only, and --restrict-read-only have been added for use with --server. New in v0.9.2 (2002/06/27) -------------------------- Interface directly with librsync(.a|.so) instead of running "rdiff" command line utility. This can significant save fork()ing time when processing lots of smallish files that have changed. Also, rdiff is no longer required to be in the PATH. Further speed optimizations, mostly reducing CPU consumption when scanning through unchanged files. Fixed Path bug which could caused globbing and regexp include/exclude statements to malfunction when the base of the source directory was "/" (root of filesystem). Thanks to Vlastimil Adamovsky for noting this bug. Added quoting for spaces in directory_statistics file, hopefully making it easier to parse. New in v0.9.1 (2002/06/19) -------------------------- Fixed some bad C. Besides being unportable and leaking memory, it may have lead to someone's backup directory getting deleted (?). Tweaked some error recovery code to make it more like 0.8.0. Improved the installation a bit. New in v0.9.0 (2002/06/17) -------------------------- Changed lots of the code to distribute as standard python package instead of single script. Installation procedure is also different. Speed optimizations - average user might see speed increase of 2 or more. New in v0.8.0 (2002/06/14) -------------------------- Added --null-separator argument so filenames can safely include newlines in an include/exclude filelist. Fixed bug that affected restoring from current mirror with the '-r now' option. New in v0.7.6 (2002/05/31) -------------------------- Improved statistics support, and added --print-statistics and --calculate-average switches. See the directory_statistics and session_statistics files in the rdiff-backup-data directory. Major improvements to error correction and resuming. Now signals SIGQUIT, SIGHUP, and SIGTERM are caught to exit more gracefully. Fixed crankyness when --exclude-filelist is the last exclude option and it is given an empty file (thanks to Bryce C for report). New in v0.7.5 (2002/05/21) -------------------------- Fixed resuming bug. After a bit of empirical testing, increased Globals.conn_bufsize and enabled ssh compression by default (and also added --ssh-no-compression option). This should speed up the "typical" remote session. Fixed bug noticed by Dean Gaudet in processing of --(include|exclude)-filelist[-stdin] options when source directory was remote. Fixed --include error reporting bug reported by Ben Edwards. Small change so 'door' files and other unknown file types will be ignored. (Thanks for Steve Simitzis for sending in a patch for this.) Fixed bug noticed by Dean Gaudet where, unless the --change-source-perms option is specified, rdiff-backup wouldn't even attempt to open files lacking ownership permissions. New in v0.7.4 (2002/05/11) -------------------------- Added new restore syntax and corresponding -r and --restore-as-of options. For instance, "rdiff-backup -r 1/3/2002 /backup/foo out" will try to restore /backup/foo (a file on the mirror directory) to out, as it was January 3rd, 2002. See man page for more information. directory_statistics.<time>.data files will now be created in the directories underneath rdiff-backup-data/increments. Just look at one to see what's inside. Added extra options --chars-to-quote, --quoting-char, and --windows-mode, mostly to allow files whose names have colons (:) in them to be backed up to windows machines. Now the -l and --list-increments switches can list the increments corresponding to any mirror file, not just the root directory. Also the option --parsable-output was added to control whether the --list-increments output looks better for a human, or computer. Improved remove-earlier-than handling so it should run approximately as fast locally and remotely. Probably fixed bug noticed by Erminio Baranzini which caused rdiff-backup to try to preserve access times unnecessarily (the default is not preserve access times). Rewrote a few large chunks of code for clarity and simplicity. Allow extended time strings for the --remove-older-than option. Added RESTORING section to the manual page because there seemed to be some general confusion about this. hardlink_data, current_mirror, and a few other files now carry the .data extension (instead of .snapshot), to make it clearer they are not copies of source files. New in v0.7.3 (2002/04/29) -------------------------- Fixed broken remote operation in v0.7.2 by applying (a variant of) Daniel Robbins' patch. Also fixed associated bug in test set. Fixed bug recognizing --[include|exclude]-filelist-stdin options, and IndexError bug reading some filelists. --force is no longer necessary if the target directory is empty. --include/--exclude/etc now work for restoring as they do for backing up. Raised verbosity level for traceback output - if long log error messages are annoying you, set verbosity to 2. Will come up with a better logging system later. May have fixed a problem encountered by Matthew Farrellee and Kevin Spicer wherein the _session_info_list information was stored on the wrong computer. This could cause rdiff-backup to fail when running after another backup that failed for a different reason. May backport this fix to 0.6.0 later. May have fixed a problem also noticed by Matthew Farrellee which can cause rdiff-backup to exit when a directory changes into a non-directory file while rdiff-backup is processing the directory. (May also apply to 0.6.0). Fixed a bug noticed by Jamie Heilman where restoring could fail if a recent rdiff-backup process which produced the backup set was aborted while processing a new directory. (May also apply to 0.6.0) New in v0.7.2 (2002/04/11) -------------------------- Added new selection options --exclude-filelist, --exclude-filelist-stdin, --exclude-regexp, --include-filelist, --include-filelist-stdin, --include-regexp. *** WARNING *** the --include and --exclude options have changed. The new --include-regexp and --exclude-regexp are close to, but still different from the old --include and --exclude options. See the man page for details. Friendlier error reporting when remote connection doesn't start. New in v0.7.1 (2002/03/25) -------------------------- Now by default .snapshot and .diff increments are compressed with python's internal gzip. The new increments format is backwards compatible, but only rdiff-backup >0.7.1 will be able to restore if any gzipped increments are present. Added --no-compression and --no-compression-regexp to control which files are compressed. New in v0.7.0 (2002/03/21) -------------------------- Added hardlink support. This is now the default, but can be turned off with --no-hardlinks. Clarified a bit of the manual. May have fixed a bug with remote handling of device files. New in v0.6.0 (2002/03/14) -------------------------- Fixed some assorted manual "bugs". Fixed endless loop bug in certain error recovery situation reported by Nick Duffek, and slightly changed around some other error correction code. Switching to new version numbering system: versions x.2n+1.x are unstable, versions x.2n.x are supposed to be more stable. New in v0.5.4 (2002/03/06) -------------------------- Fixed bug present since 0.5.0 wherein rdiff-backup would make snapshots instead of diffs when regular files change. May have fixed race condition involving rdiff execution. New in v0.5.3 (2002/03/03) -------------------------- It turns out the previous version broke device handling. Sorry about that.. New in v0.5.2 (2002/03/02) -------------------------- Fixed bugs which made rdiff-backup try to preserve mod times when it wasn't necessary, and exit instead of warning when it wasn't being run as root and found a file it didn't own. (Reported by Alberto Accomazi.) Added some more error checking; maybe this will fix a bug reported by John Goerzen wherein rdiff-backup can crash if file is deleted while rdiff-backup is processing it. Changed locations of some of the temp files; filenames will be determined by the tempfile module. New in v0.5.1 (2002/02/22) -------------------------- When establishing a connection, print a warning if the server version is different from the client version. When find rdiff error value 256, tell user that it is probably because rdiff couldn't be found in the path. Fixed a serious bug that can apparently cause a remote backups to fail (reported by John Goerzen). May have fixed a bug that causes recovery from certain errors to fail. New in v0.5.0 (2002/02/17) -------------------------- Now every so often (default is 20 seconds, the --checkpoint-interval option controls it) rdiff-backup checkpoints by dumping its state to temporary files in the rdiff-backup-data directory. If rdiff-backup is rerun with the same destination directory, it can either try to resume the previous backup or at least clean things up so the archive is consistent and accurate. Added new options --resume, --no-resume, and --resume-interval, which control when rdiff-backup tries to resume a previous failed backup. Fixed a bug with the --exclude-device-files option which caused the option to be ignored when the source directory was remote. By default, if rdiff-backup encounters a certain kind of IOError (currently types 26 and 5) while trying to access a file, it logs the error, skips the file, and tries to continue. If settings requiring an integer argument (like -v or --checkpoint-interval) are given a bad (non-integer) argument, fail with better explanation. Fixed annoying logging bug. Now no matter which computer a logging message originates on, it should be routed to the process which is writing to the logging file, and written correctly. However, logging messages about network traffic will not be routed, as this will generate more traffic and lead to an infinite regress. When calling rdiff, uses popen2.Popen3 and os.spawnvp instead of os.popen and os.system. This should make rdiff-backup more secure. Thanks to Jamie Heilman for the suggestion. Instead of calling the external shell command 'stat', rdiff-backup uses os.lstat().st_rdev to determine a device file's major and minor numbers. The new method should be more portable. Thanks to Jamie Heilman for the suggestion. All the file operations were examined and tweaked to try to minimize/eliminate the chance of leaving the backup directory in an inconsistent state. Upon catchable kinds of errors, try to checkpoint before exiting so later rdiff-backup processes have more information to work with. At the suggestion of Jason Piterak, added a --windows-time-format option so rdiff-backup will (perhaps) work under MS windows NT. New in v0.4.4 (2002/01/09) -------------------------- Applied Berkan Eskikaya's "xmas patch" (I was travelling and didn't have a chance on Christmas). He fixed important bugs in the --terminal-verbosity and --remove-older-than options. Added an --exclude-device-files option, which makes rdiff-backup skip any device files in the same way it skips files selected with the --exclude option. New in v0.4.3 (2001/12/17) -------------------------- Plugged another memory hole. At first I thought it might have been python's fault, but it was all me. If rdiff-backup uses more than a few megabytes of memory, tell me because it is probably another memory hole.. rdiff-backup is now a bit more careful about deleting temporary files it creates when it is done with them. Changed the rpm spec a little. The enclosed man page is gzipped and the package file is GPG signed (it can be checked with, for example, "rpm --checksig -v rdiff-backup-0.4.3-1.noarch.rpm"). rdiff-backup no longer checks the mtimes or atimes of device files. Use of these times was inconsistent (sometimes writing to device files updates their times, sometimes not) and leads to unnecessary backing up of files. New in v0.4.2 (2001/11/19) -------------------------- Significant speed increases (maybe 20% for local sessions) when dealing with directories that do not need to be updated much. Fixed memory leak. rdiff-backup should now run in almost constant memory (about 6MB on my system). Enabled buffering of object transfers, so remote sessions can be 50-100%+ faster. rdiff-backup now thinks it is running as root if the destination connection is root. Thus rdiff-backup will preserve ownership even if it is not running as root on the source end. If you abort rdiff-backup or it fails for some reason, it is now more robust about recovering the next time it is run (before it could fail in ways which made subsequent sessions fail also). However, it is still not a good idea to abort, as individual files could be in the process of being written and could get corrupted. If rdiff-backup encounters an unreadable file (or, if --change-source-perms is given, a file whose permissions it cannot change), it will log a warning, ignore the file, and continue, instead of exiting with an error. New in v0.4.1 (2001/11/9) ------------------------- Now either the source, or the target, or both can be remote. To make this less confusing, now rdiff-backup supports host::file notation. So it is legal to run: rdiff-backup bill@host1.net::source_file jones@host2.net::target Also, the test suites have been improved and found a number of bugs (which were then fixed). New in v0.4.0 (2001/11/4) ------------------------- Much of the rdiff-backup internals were rewritten. The result should be better performance when operating remotely over a pipe with significant latency. Also the code dealing with changing permissions is much cleaner, and should generalize later to similar jobs (for instance preserving atimes.) Listing and deleting increments and restoring should work remotely now. In earlier versions a file or directory had to be restored locally and then copied over to its final destination. At the request of the FSF, a copy of the GPL has been included in the packaged distributions. It is in the file "COPYING". New in v0.3.4 (2001/10/31) -------------------------- A change in python from the 2.2a series to 2.2b series made remote backup on version 0.3.3 stop work, a small change fixes it. (Thanks to Berkan Eskikaya for telling me about this.) Listed some missing features/bugs on the manual page. New in v0.3.3 (2001/10/16) -------------------------- Changed quoting system yet again after learning that the old system was not very portable between shells (thanks Hans <hguevremont@eternitee.com>) New in v0.3.2 (2001/10/9) ------------------------- Added --list-increments and --remove-older-than commands. --list-increments will just tell you what increments you have and their dates. This isn't anything you couldn't get from "ls", but it may be formatted more nicely. The --remove-older-than command is used to delete older increments that you don't want, or don't have space for. Also, on some systems ssh was adding a spurious "Broken pipe" message, even though everything went fine. Maybe this version will prevent this confusing message. New in v0.3.1 (2001/9/11) ------------------------- Fix for stupid bug - when running remotely as users with different uids, rdiff-backup now doesn't check the uid/gid. Before it kept thinking that the files needed to be updated because they didn't have the right ownership. This shouldn't have resulted in any data loss - just some unnecessary .rdiff files. (Thanks to Michael Friedlander for finding this.) Added check to make sure that rdiff exits successfully. New in v0.3.0 (2001/9/9 - Billennium edition) --------------------------------------------- rdiff-backup has been almost completely rewritten for v0.3.0, as it was for v0.1.0. The main problem with versions 0.2.x was that the networking code was added to the not-remote-capable v0.1, and the result was unyieldy and prone to bugs when operating over a pipe. There are some new features: - Hopefully very few bugs, at least in basic file handling. rdiff-backup has an extensive testing suite now, so it should be much more reliable. - Complete support for reading and writing from and to files and directories that lack permissions, by temporarily changing them, and then changing them back later. (See for instance the --change-source-perms switch.) As I found out there is a lot to this, so much that I'm not sure in retrospect I should have bothered. :-) - New more standard format for increment files. See http://www.w3.org/TR/NOTE-datetime for the time standard. The old format, besides being less standard, didn't take timezones into account. - In the initial mirroring, rdiff-backup only copies the files that it needs to, so it is much quicker when you almost have an initial mirror already. You can even the --mirror-only switch and make rdiff-backup into a slow version of rsync. - Terminal and file verbosity levels can be selected separately. So if you like a lot in your backup.log/restore.log but not much on your terminal, or vice-versa, you can set them at different numbers. - New --test-server option so if something goes wrong you can see if it is because the server on the other side isn't being initialized properly. - New --no-rdiff-copy option, which disables using rdiff to move files across a connection (it will still be used to make increment files however). If the bottleneck is not bandwidth but local disks/CPUs, this options should speed things up. There are, however, a few negatives: - rdiff-backup now requires Python version 2.2 or later. Sorry for the inconvenience but I use the new features a lot. - It may be slightly slower overall than versions 0.2.x - the remote code is cleaner, but probably has higher overhead. At least on my computer, rdiff-backup is still quicker than rsync for local mirroring of large files, but for remote mirroring, rsync will usually be much quicker, because it uses a fairly low-overhead pipelining protocol. - Any old increments are incompatible because they use a different date/time standard. If this is a big deal, try mailing me. A converter shouldn't be very difficult to write, but I didn't want to take the time unless someone really wanted it. New in v0.2.8 (2001/9/4) ------------------------- Fixed two stupid bugs that would cause rdiff-backup to exit with an exception. (I can't believe they were in there.) New in v0.2.7 (2001/8/29) ------------------------- Added new long options --backup-mode and --verbosity which are equivalent to -b and -v. rdiff-backup should be a little more resistant to the filesystem it is backup up changing underneath it (although it is not setup to handle this in general). Thanks Alberto Accomazzi <aaccomazzi@cfa.harvard.edu> for these suggestions. New in v0.2.6 (2001/8/27) ------------------------- Fixed bug where, for non-root users, rdiff-backup could, in the process of mirroring an unwritable directory, make the copy unwriteable and then fail. Now rdiff-backup goes through and makes what it needs to be readable and writeable, and then changes things back at the end. (Another one found by Jeb Campbell!) New in v0.2.5 (2001/8/26) ------------------------- Added better error reporting when server throws an exception. Fixed bug so that backed-up setuid files will also be setuid. Now rdiff-backup thinks it's running as root only if both client and server are running as root (Thanks to Jeb Campbell for finding these previous two bugs). Fixed miscellaneous Path bug that could occur in remote operation. New in v0.2.4 (2001/8/25) ------------------------- Added more logging options that may help other track down a mysterious bug. New in v0.2.3 (2001/8/24) ------------------------- Fixed typing bug that caused an Assertion Error in remote operation, thanks again to Jeb Campbell for finding it. New in v0.2.2 (2001/8/24) ------------------------- Fixed bug in remote creation of special files and symlinks (thanks to Jeb Campbell <jebc@c4solutions.net> for finding it). Fixed another error report. New in v0.2.1 (2001/8/7) ------------------------ Now if rdiff-backup isn't running as root, it doesn't try to change file ownership. Fixed an error report. Stopped flushing an open pipe to fix a race condition on IRIX. New in v0.2 (2001/8/3) ---------------------- rdiff-backup can now operate in a bandwidth efficient manner (a la rsync) using a pipe setup with, for instance, ssh. I was too hasty with the last bug fix and didn't deal with all filenames properly. Maybe this one will work. New in v0.1.1 (2001/8/2) ------------------------- Bug fix: Filenames that may contain spaces, backslashes, and other special characters are quoted now and should be handled correctly. New in v0.1 (2001/7/15) ---------------------- Large portion (majority?) of rdiff-backup was rewritten for v0.1. New version highlights: - No new features! - No speed improvements! It may even be slower... - No bug fixes! (ok maybe a few) However, the new version is much cleaner and better documented. This version should have fewer bugs, and it should be easier to fix any future bugs.
