21 # Version __VERSION__, __RELEASEDATE__
22 #------------------------------------------------------------------------
24 * Add config file editing.
26 * Added Portuguese Brazillian pt_br.pm from Reginaldo Ferreira.
28 * Added Slackware init.d script from Tony Nelson.
30 * Fixed error reporting when restore/archive fail to write the
31 request file to the client directory.
33 * Applied patch from Marc Prewitt for DumpPreShareCmd and DumpPostShareCmd.
35 * Apply patch from Pete Wenzel to add smbClientPath => $Conf{SmbClientPath}
36 to DumpPreUserCmd etc.
38 * Applied Lorenzo Cappelletti's it.pm patch.
40 * Applied patch to bin/BackupPC_sendEmail from Marc Prewitt that
41 ignores any file starting with "." in the pc directory when
42 it is generating warnings about old/unused files/directories.
44 * Applied patch from Marc Prewitt to fix host queue order.
46 * Add NT_STATUS_FILE_LOCK_CONFLICT to pst read error check in
47 BackupPC_sendEmail to fix bug reported by Dale Renton.
49 * Fixed minor typo in documentation from Richard Ames
51 #------------------------------------------------------------------------
52 # Version 2.1.0pl1, 15 Aug 2004
53 #------------------------------------------------------------------------
55 * Added fix to nl.pm from Lieven Bridts.
57 * Added patch from Tony Nelson to remove $Info{pid} before BackupPC
58 writes the status and shuts down.
60 * Changed BackupPC_nightly so that it doesn't call find() if the
61 directory doesn't exist. This avoids errors in certain versions
62 of perl. Reported by Bernd Rilling.
64 * Fixed BackupPC::CGI::Lib to correctly re-load config.pl for mod_perl.
65 Reported by Tony Nelson and Jimmy Liang.
67 * Explicitly untaint $In{host} in BackupPC::CGI::Lib to fix problem
68 reported by Thomas Tempé.
70 * Added newline to "...skipping because of user requested delay..."
71 log message in BackupPC_dump. Reported by Wayne Scott.
73 * Added read file size error checking to BackupPC_tarCreate.
74 Reported by Brandon Evans.
76 * Added check in BackupPC::Xfer::RsyncFileIO to ensure that when
77 compression is toggled on/off, a compressed backup doesn't link
78 to an uncompressed pool file (and an uncompressed backup doesn't
79 link to a compressed pool file). Reported by Brandon Evans.
81 * Updated documentation with new dirvish URL and a typo from
84 * Fix to BackupPC_sendEmail so that it correctly sends admin emails
85 for hosts that have failed backups. Reported by Simon Kuhn.
87 #------------------------------------------------------------------------
88 # Version 2.1.0, 20 Jun 2004
89 #------------------------------------------------------------------------
91 * Added Dutch translation from Lieven Bridts, with tweaks from
94 * Added PC-specific config file read in CGI/Archive.pm. Patch
97 * Added non-zero exit code to BackupPC_zcat when uncompress fails.
98 Patch from Pete Wenzel.
100 * Cosmetic changes to PC Summary and Log file language strings from
103 * BackupPC::Lib tries to be more careful when renaming the backups
104 file to backups.old. There have been reports of backups being
105 empty, perhaps when the BackupPC data file system fills up.
106 Now backups is not renamed to backups.old if backups is empty.
108 * BackupPC now closes stderr and stdout before renaming and
109 re-opening the log file.
111 * Pre/post backup/restore/archive commands now correctly set
112 "type" to either incr/full/restore/archive, and now cmdType
113 is the type of Pre/post backup/restore/archive command.
115 * BackupPC_archive correctly terminates archive processes on
118 * Updates to BackupPC_stnd.css with absolute font sizes instead
121 * BackupPC_dump now makes sure that the $Conf{FullAgeMax} check
122 also ensures the full backup is older than the maximum age
123 expected from $Conf{FullPeriod}.
125 #------------------------------------------------------------------------
126 # Version 2.1.0beta2pl1, 30 May 2004
127 #------------------------------------------------------------------------
129 * Fixed bug in rsync checksum caching code in BackupPC::Xfer::RsyncDigest.
131 * BackupPC_zipCreate now ensures the earliest mtime is 1/1/1980,
132 since zip file formats don't support earlier dates. Reported
135 * CGI restore via zip and tar now makes sure stderr is ignored
136 when BackupPC_tarCreate and BackupPC_zipCreate are run.
137 Previously any stderr output would get mixed in the archive,
138 corrupting it. Reported by Dan Niles.
140 #------------------------------------------------------------------------
141 # Version 2.1.0beta2, 23 May 2004
142 #------------------------------------------------------------------------
144 * $Conf{BackupFilesOnly} and $Conf{BackupFilesExclude} now apply
145 to every share, rather than just the first, in the case where
146 they are arrays and there are multiple shares. Suggested
149 * On the phase 2 retry pass with rsync, verify the cached checksums
150 if checksum caching is turned on. This will catch the case of
151 cached checksums being incorrectly appended to the compressed
152 pool file. Added new config parameter $Conf{RsyncCsumCacheVerifyProb}
153 so that cached checksums are verified with a selectable probability.
154 Also, increased File::RsyncP version number to 0.51.
156 * configure.pl now supports an optional batch mode. Command-line
157 options are used to specify all the information that configure.pl
158 needs. This is useful for building auto-install packages.
159 Also, configure.pl now includes pod documentation, so you can do
160 "perldoc configure.pl" to see all the command-line options.
161 Suggested, tested and tweaked by Stuart Herbert for possible
164 * At each wakeup, clients are now queued based on how old the most
165 recent backup is. Clients with errors are queued first, with
166 the oldest error times going first. The rest of the clients are
167 queued next, with the clients with the oldest backup going first.
168 Previously the clients were simply queued in alphabetic order.
169 Suggested by Mike Trisko and Tony Nelson.
171 * Added config parameter $Conf{PartialAgeMax} that controls whether
172 partials are saved at all, and if so, whether the partial will be
173 ignored at the next full backup if it is too old.
175 * BackupPC_tarExtract now allows empty archives without reporting
176 an error. Reported by Don Silvia.
178 * Removed Browse Backups link from Nav Bar in Archive Info display.
179 Reported by Ralph Paßgang.
181 * Fixed documentation display for regular users. Reported by Ralph Paßgang.
183 * Status and PC Summary now work for regular users and only show
184 that user's hosts. Server general status information only appears
185 for admins. Suggested by Ralph Paßgang.
187 * Moved the last three navigation-bar links (docs, FAQ and SF) to
188 a new config parameter $Conf{CgiNavBarLinks}. This allows
189 these links to be locally configured. Based on a patch
190 submitted by Ralph Paßgang.
192 * Allow the navigation bar search box to be disabled by
193 setting $Conf{CgiSearchBoxEnable} to 0. Based on a patch
194 submitted by Ralph Paßgang.
196 * Updates to de.pm from Ralph Paßgang.
198 * Made the BackupPC icon a link to the SF BackupPC project page.
200 #------------------------------------------------------------------------
201 # Version 2.1.0beta1, 4 Apr 2004
202 #------------------------------------------------------------------------
204 * The CSS definition has been removed from the config.pl file and
205 is now a separate file, BackupPC_stnd.css. A new config variable,
206 $Conf{CgiCSSFile}, gives the name of the CSS file to use.
207 Suggested by Ender Mathias.
209 * Fixed the filling of the host name select box for admins.
210 The default $Conf{CgiNavBarAdminAllHosts} is now 1.
211 Reported by Doug Lytle.
213 * Cleaned up warning message for restore using rsync when checksum
214 caching is on, but when file didn't have cached checksums.
216 * Fixed BackupPC_archiveHost to support par2 (par2cmdline).
217 Patch submitted by Jaco Bongers and adapted by Josh Marshall.
219 * Improved stat() usage in BackupPC_nightly, plus some other cleanup,
220 giving a significant performance improvement. Patch submitted by
223 * Allow several BackupPC_nightly processes to run in parallel based
224 on new $Conf{BackupPCNightlyJobs} setting. This speeds up the
225 traversal of the pool, reducing the overall run time for
228 * Allow BackupPC_nightly to split the pool traversal across several
229 nightly runs. This improves the running time per night, at the expense
230 of a slight increase in disk storage as unused pool files might not
231 be deleted for a couple of days. Controller by new config setting
232 $Conf{BackupPCNightlyPeriod}.
234 #------------------------------------------------------------------------
235 # Version 2.1.0beta0, 20 Mar 2004
236 #------------------------------------------------------------------------
238 * A failed full dump is now saved as a partial (incomplete) dump,
239 provided it includes some files. This can be used for browsing,
240 restoring etc, and will also form the basis of resuming full
241 dumps. Only one partial is kept, and it is removed as soon
242 as a successful full (or a new partial) is done.
244 * Added support for resuming a full dump for rsync. The partial
245 full is kept, and to resume an incremental is done against the
246 partial, and a full is done for the rest.
248 * Added support for Rsync checksum caching. Rsync checksum are
249 appended to the compressed pool files. This means that block
250 and file checksums do not need to be recomputed on the server
251 when using rsync. Requires a patch to rsync to support fixed
252 checksum seeds. This patch is included in the cygwin-rsyncd
253 release on http://backuppc.sourceforge.net.
255 * Major addition of Archive feature from Josh Marshall. Special
256 clients can be configured to be archive targets (eg: tape drives,
257 CD-R). Any subset of the backup clients can be selected and tar
258 archives are created, optionally compressed and split and written
259 to the output device. Logs are maintained and are browsable.
261 * Major changes from Ryan Kucera to add style sheets to the CGI
262 interface, allowing easy customization. Added new icons and
263 BackupPC logo. Numerous navigation improvements.
265 * Added directory history display to BackupPC_Admin, allowing the
266 user to quickly see which files changed between backups on a
269 * Added exponential expiry option for full dumps. This allows you
272 - how many fulls to keep at intervals of $Conf{FullPeriod}, followed by
273 - how many fulls to keep at intervals of 2 * $Conf{FullPeriod},
274 - how many fulls to keep at intervals of 4 * $Conf{FullPeriod},
275 - how many fulls to keep at intervals of 8 * $Conf{FullPeriod},
276 - how many fulls to keep at intervals of 16 * $Conf{FullPeriod},
278 and so on. This allows you, for example, to keep 4 weekly fulls,
279 followed by 6 fulls every 4 weeks (approx 1 month) and 2 fulls at
280 16 weeks, for roughly 1 year of history. This works by deleting
281 every other full as each expiry boundary is crossed. Suggested
284 * Added Italian language translation it.pm from Lorenzo Cappelletti.
286 * Major updates to language files for new features and tags changes.
287 Updated makeDist to do pedantic consistency checking of language
290 * Addition of administration options from Paul Lukins. Initial
291 page allows server to be started/stopped/reloaded. This still
292 needs some i18n work. Currently the server start/stop is
295 * Split BackupPC_Admin into a set of modules, one for each major action.
296 Each action is now a seperate module in lib/BackupPC/CGI.
298 * Allow the blackout period begin/end to span midnight. Adapted
299 from patch submitted by David Smith.
301 * Allow multiple blackout periods, with new config variable
302 $Conf{BlackoutPeriods} that replaces the old variables
303 $Conf{BlackoutHourBegin}, $Conf{BlackoutHourEnd}, and
304 $Conf{BlackoutWeekDays}. Based on patch submitted by
307 * Disabled alarms after forks to avoid timeouts in children that
308 do not reset their alarm. Prompted by ideas from James Leu.
310 * Added options for block size, buffer size and share wild-card to
311 BackupPC_tarCreate. Also added negative backup number options
312 that are relative to the last (so -1 is the last), suggested by
313 William McKee and Carl Soderstrom.
315 * The "Wrong user" message in BackupPC::Lib now goes to stderr, so that
316 the user is more likely to see the error with BackupPC_tarCreate.
317 Reported by Paul Fox.
319 * Add creation of per-PC directory in BackupPC/CGI/Restore.pm in
320 case it doesn't already exist.
322 * Added -q -x to all ssh commands in conf/config.pl. Suggested by
323 SI Reasoning and Niranjan Ghate.
325 * Changed restore code so that option #1 (direct restore) can be
326 disabled if the restore command is undefined. Disabling direct
327 restore is necessary if the share is read-only. Suggested by
330 * Changed regexp in lib/BackupPC/Smb.pm to allow numbers with both
331 a decimal point or comma for international versions of Samba.
332 Patch submitted by Frank Gard.
334 * Browsing and directory history now sort the files in a
335 case-insensitive manner.
337 * Changed exec() syntax to allow executing commands whose path
340 * BackupPC_dump no longer removes backups if $Conf{FullKeepCnt}
341 is zero or undefined. The protects the existing backups in the
342 case of a bad config.pl file. Suggested by Christian Warden.
344 * Swapped the Server and Hosts sections on the Nav bar. Moved the
345 host search text box to the top of the hosts section. This was
346 done to move the variable-length part of the Nav bar (when all
347 hosts are displayed) to the bottom.
349 * Fixed a bug in tar restore related to how the common prefix path is
350 removed. Now ensure that the common path is at a directory boundary.
351 Reported by Patrick Neuner.
353 * Added --chuid ${USER} to init.d/src/gentoo-backuppc. Suggested by
354 SI Reasoning, Pascal Pochol, Michael Evanoff and others.
356 * Added Suse notes to init.d/README from Bruno Vernay.
358 * Added Apache 2 documentation fix from Michael Tuzi.
360 #------------------------------------------------------------------------
361 # Version 2.0.2, 6 Oct 2003
362 #------------------------------------------------------------------------
364 * Fixed stupid last-minute change in octal size conversion in
367 #-----------------------------------------------------------------------
368 # Version 2.0.1, 5 Oct 2003
369 #------------------------------------------------------------------------
371 * Fixed handling of >= 8GB files in BackupPC_tarExtract and >= 4GB
372 files in BackupPC_tarCreate.
374 * Removed smbclient size repair in BackupPC_tarExtract for files
375 between 2GB and 4GB. This means that BackupPC_tarExtract 2.0.1
376 doesn't behave the same as 2.0.0 for file sizes between 2GB and 4GB
377 extacted using smbclient 2.2.x. If you have problems backing up
378 files whose size is between 2GB and 4GB using smbclient 2.2.x
379 you should upgrade smbclient to 3.0, since it now generates
382 * Replace PingClientPath with PingPath in configure.pl.
384 * Removed -T (taint mode) on binaries installed in configure.pl.
386 * Added support for smbclient from samba version 3.0.0.
388 * Fixed $Conf{HardLinkMax} limit check in BackupPC::Lib; reported
391 * In BackupPC_Admin, default REMOTE_USER to $Conf{BackupPCUser}
392 if it is not defined. This allows the CGI interface to work
393 when AdminUsers = '*'. Reported by Quentin Arce.
395 * For SMB, code that detected files with a read-locked region (eg:
396 outlook .pst files), removed them and then tried to link with an
397 earlier version was broken. This code missed a step of mangling
398 the file names. This is now fixed. Reported by Pierre Bourgin.
400 * A backup of a share that has zero files is now considered
401 fatal. This is used to catch miscellaneous Xfer errors that
402 result in no files being backed up. A new config parameter
403 $Conf{BackupZeroFilesIsFatal} (defaults to 1) and can be set to
404 zero to turn off this check. Suggested by Guillaume Filion.
405 Additional change: this check only applies to a full dump.
407 * SMB: now detect NT_STATUS_ACCESS_DENIED on entire share or BackupFilesOnly
408 (also ERRDOS - ERRnoaccess (Access denied.) for older versions of
409 smbclient.) Suggested by Guillaume Filion.
411 * SMB: now detects "tree connect failed: NT_STATUS_BAD_NETWORK_NAME" and
412 the dump is considered failed.
414 * Rsync: Previously BackupFilesOnly = '/' did --include '/' --exclude '/*',
415 which just included the '/' directory and nothing below. Now it
416 does just --include '/', which should include everything.
419 * Add hostError to DumpPostUserCmd variable substitutions for both dump
422 * Verbose output in Lib.pm goes to STDERR, not STDOUT. This now
423 makes BackupPC_dump -v work better.
425 * Don't allow browsing with ".." in directory in case a user tries
426 to trick BackupPC_Admin into displaying directories outside where
429 * Required File::RsyncP version is now 0.44, since File::RsyncP 0.44
430 fixes large file (>2GB) bugs. Large file bugs reported by Steve
433 #------------------------------------------------------------------------
434 # Version 2.0.0, 14 Jun 2003
435 #------------------------------------------------------------------------
437 * Minor tweaks to disable utf8 on utf8-capable machines (eg: RH8+).
438 Added "no utf8" to all programs, and added binmode() to relevant
441 #------------------------------------------------------------------------
442 # Version 2.0.0beta3, 1 Jun 2003
443 #------------------------------------------------------------------------
445 * Several improvements to restore: cancel now reports the correct
446 message and cleans up correctly.
448 * Rsync with whitespace and wildcard excludes fixed by replacing
449 argList with argList+ in config.pl plus a fix to Lib.pm for
450 shell escaping array arguments.
452 * Fixed rsync restore for character and block special devices
453 (major and minor device numbers weren't correctly restored).
455 * Fixed typo in bin/BackupPC_restore (XferLOG -> RestoreLOG).
457 * (Re)-fixed "Bad command" in log file when restore via tar or zip
458 file download is done.
460 * Added untaint to exec in Lib.pm to avoid tainted errors.
462 * Applied additional tweak to hilight patch from Tim Demarest.
464 * $Conf{CgiAdminUsers} = '*' now allows privileged even with REMOTE_USER
467 * Don't display RsyncdPasswd when displaying config.pl files.
469 * Replace pipe with socketpair in bin/BackupPC_dump and bin/BackupPC_restore,
470 which increases typical buffering from 4K to 16K-64K. This improves the
473 * Add check on $ENV{LANG} setting do configure.pl: if LANG includes utf
474 then a warning is printed.
476 #------------------------------------------------------------------------
477 # Version 2.0.0beta2, 11 May 2003
478 #------------------------------------------------------------------------
480 * Added German translation, provided by Manfred Herrmann.
482 * Fixed large-file problem with rsync, reported by Manfred Herrmann.
484 * Fixed zip and tar file download from CGI under mod_perl. Reported
485 by Pierre Bourgin and Paul Lukins.
487 * Fixed directory browsing and top-level directory browsing in 2.0.0beta0.
488 Reported by several users.
490 * Added -v option to BackupPC_dump for verbose output (useful when
491 you run the command manually). Added messages for all exits.
493 * If nmblookup returns multiple IP addresses, NetBiosHostIPFind()
494 now returns the first IP address that matches the subnet mask.
495 Suggested by Tim Demarest.
497 * Fixed BackupPC::View so the top-level directory is handled correctly.
498 This allows the top-level share/directory to be restored via the
499 CGI interface. Reported by several users.
501 * Fixed RsyncFileIO failures on certain large files by replacing seek()
502 with sysseek(). Reported by Manfred Herrmann.
504 * Added configurable highlighting of PC status in the CGI summary
505 screen; submitted by Tim Demarest.
507 * Fixed command queue CGI display; submitted by Tim Demarest.
509 * BackupPC_trashClean now logs an error if it can't remove all the
510 trash and then goes back to sleep, rather than continually trying.
512 * Moved correct user (uid) check into BackupPC::Lib so that all
513 applications do a user check if $Cong{BackupPCUserVerify} is
514 set. The avoids the risk of manually running BackupPC_dump as
517 * Loss of blackout now applies to "host not found" as well as no ping.
518 Reported by Dale Renton.
520 * "Host not found" is now treated in a similar manner to "no ping".
522 * Added suse-linux init.d script from Leon Letto.
524 * Added Gentoo linux init.d script from Tim Demarest.
526 * Applied additional i18n strings from GFK and the translation team.
528 * Fixed option parsing so that getopts errors are reported and we exit.
530 * Changed reporting of Xfer PIDs so that rsync cancel works correctly.
532 #------------------------------------------------------------------------
533 # Version 2.0.0beta1, 30 Mar 2003
534 #------------------------------------------------------------------------
536 * Added Spanish translation es.pm from Javier Gonzalez.
538 * Fixed CGI browse navigation bug that causes BackupPC_Admin to wedge
539 when directories were selected in a certain order.
541 * Fixed BackupPC::PoolWrite so that it can recover when the initial
542 file size is wrong. This is needed since rsync could write a file
543 whose size is different from the initial size returned in the
544 file list when that file is updated while rsync is running.
546 * Added binmode(STDIN) to BackupPC_tarExtract, suggested by Pat LoPresti
547 to fix a problem a RedHat8 with perl 5.8.0. It's unclear why this
548 helps, but it should be benign. See:
549 http://sourceforge.net/mailarchive/forum.php?thread_id=1853018&forum_id=503
551 #------------------------------------------------------------------------
552 # Version 2.0.0beta0, 23 Feb 2003
553 #------------------------------------------------------------------------
555 * Support for rsync and rsyncd backup and restore. Changes to
556 BackupPC_dump, BackupPC_restore, and new modules BackupPC::Xfer::Rsync
557 and BackupPC::Xfer::RsyncFileIO.
559 * Added internationalization (i18n) code from Xavier Nicollet,
560 with additions from Guillaume Filion. Voila! BackupPC_Admin
561 now supports English and French, and adding more languages is
562 now easy. New config paramater $Conf{Language} sets the language.
564 * Added optional user-defined pre/post dump/restore commands, allowing
565 things like database shutdown/startup for dumps.
567 * Changed the way hosts are found.
569 * Added $Conf{ClientNameAlias}, which allows the name of the physical
570 client machine to be set. This allows several different backup
571 "hosts" to all refer to the same physical machine, which is
572 convenient if several different types of data need to be backed
573 up, or if different parameters are needed for different parts of
576 * Replaced $Conf{PingArgs} with $Conf{PingCmd}, added $Conf{DfCmd},
577 $Conf{NmbLookupCmd} allowing all these commands to be fully
578 configured. Also, all commands can also now be fragments of
581 * Moved all smbclient commands into the config.pl file so the specific
582 arguments can be customized. New config parameters are
583 $Conf{SmbClientFullCmd}, $Conf{SmbClientIncrCmd} and
584 $Conf{SmbClientRestoreCmd}.
586 * Added new BackupPC::View module that creates views of backups
587 (handling merging etc). Updated BackupPC_Admin, BackupPC_zipCreate
588 and BackupPC_tarCreate to use BackupPC::View. This removes lots
589 of merging and mangling code from the higher-level code.
591 * Added code from Toby Johnson that allows additional users to be
592 specified in the hosts file; these users can also view/start/stop
593 and restore backups for that host. Also added a new config
594 setting $Conf{CgiNavBarAdminAllHosts} that allows all hosts to
595 be listed in the left nav bar for admins.
597 * Added $Conf{HardLinkMax} (default 31999) which sets the limit on
598 the maximum number of hardlinks per file in the pool. If a file
599 ever gets to this number of links a new pool file is created to
600 handle additional links.
602 * Added $Conf{PerlModuleLoad}, which allows optional additional perl
603 modules to be loaded.
605 * Added $Conf{EMailUserDestDomain} and other EMail config settings to
606 allow language-specific default messages to be overridden.
608 * Added BPC_FTYPE_DELETED to lib/BackupPC/Attrib.pm, allowing deleted
609 files to be represented in the attrib file correctly.
611 * Added support for environment variable BPC_SMB_PASSWD, which is the
612 client's smb password. This overrides the old environment variable
615 * Added taint cleanup for perl5.8 to lib/BackupPC/Lib.pm.
617 * Changed $tar_unpack_header format in BackupPC_tarExtract to correctly
618 handle files with trailing spaces.
620 * Added catching of SIG_PIPE to BackupPC_dump, and changed catch_signal
621 to ignore multiple signals of the same type.
623 * Added reporting of the largest number of hardlinks in the pool to the
626 * Adding reporting of syntax errors in the per-PC config.pl file.
628 * Updated BackupPC_sendEmail to handle language-specific email messages.
630 * Allow client (host) names to contain spaces. Spaces in host names
631 need to be escaped via "\" in the hosts file. The user of spaces in
632 host names is discouraged, but they should work. One feature that
633 doesn't work with host names that contain spaces is the highlighting
634 of that name in the log file display in the CGI interface. There are
635 no plans to fix this.
637 * Renamed $Conf{SmbClientTimeout} to $Conf{ClientTimeout}.
639 * Fixed all open() calls to use 3 argument form to fix handling of file
640 names with trailing whitespace. Also fixed CGI interface so these
641 file names are displayed correctly.
643 * Fixed new 2.0.0 CGI navigation bug that causes the top-level directory
644 to have a URL "&share=//boot&dir=" instead of "&share=/boot&dir=/".
645 Reported by Pascal Schelcher. Fixed similar problem reported by
648 * Added "PerlTaintCheck On" to the mod_perl section in the docs,
649 suggested by Tim Demarest.
651 #------------------------------------------------------------------------
652 # Version 1.5.0, 2 Aug 2002
653 #------------------------------------------------------------------------
655 * Changed conf/config.pl so that $Conf{TarIncrArgs} uses the --newer
656 option instead of --newer-mtime. Also removed --atime-preserve from
657 $Conf{TarClientCmd}. This makes the default settings work better
660 * Fixed configure.pl so it correctly detects a running BackupPC <= v1.4.0
661 so it can correctly warn the user to stop it before upgrading. Reported
664 * Added missing ";" to entity escape in EscapeHTML in BackupPC_Admin.
665 Reported by Guillaume Filion.
667 * Added LDAP setup to documentation from David Holland.
669 * Tar.pm now adds a "." to file paths that start with "/", so that all
670 tar paths are relative. From Ludovic Drolez.
672 #------------------------------------------------------------------------
673 # Version 1.5.0beta0, 30 Jun 2002
674 #------------------------------------------------------------------------
676 * A full set of restore options is now supported, including direct
677 restore via smbclient or tar or downloading a zip or tar file.
679 * Major additions to CGI script to support better directory navigation,
680 restore features and mod_perl. Also, file downloads from the CGI
681 interface now correctly preserve the file name and provide the
682 correct Content-Type for the most common types of files. Improved
683 directory navigation was contributed by Ryan Kucera.
685 * New script BackupPC_zipCreate (contributed by Guillaume Filion) is the
686 zip analog of BackupPC_tarCreate. BackupPC_zipCreate can be used to
687 create a zip archive of any portion of a backup.
689 * Substantial additions to BackupPC_tarCreate to support restore,
690 including modifying path names, handling hardlinks, fixing
691 support of old backups without attributes (pre-v1.4.0). Plus
692 BackupPC_tarCreate is now an offical part of the release.
693 (Lack of support for hardlinks was reported by John Stanley.)
695 * BackupPC_tarExtract now supports hardlinks and fixed pooling of
698 * A unix domain socket is now used for communication between the CGI
699 interface and BackupPC. The original TCP socket is optional. Sockets
700 are correctly re-initialized if config.pl is updated with new socket
703 * For improved security messages over the unix or TCP socket are protected
704 via an MD5 digest based on a shared secret, a sequence number, a time
705 stamp and a unique per-connection number.
707 * Additions to configure.pl to support install of directory navigation
710 * Fixed case where $Conf{BackupFilesOnly} or $Conf{BackupFilesExclude}
711 were set to a single string or list (in v1.4.0 only the case of
712 hash worked correctly). Reported by Phillip Bertolus.
714 * Fixed case of $Conf{BackoutGoodCnt} == 0. This setting now makes the
715 client always subject to blackout, matching the comments in config.pl.
716 Also fixed handling of $Conf{BackoutGoodCnt} < 0 in the CGI script
717 reported by Pascal Schelcher.
719 * Fixed byte and file totals for tar backups, reported by several users.
721 * Fixed --newer-mtime date/timestamp format to make it ISO 8601 compliant,
722 suggested by Erminio Baranzini.
724 * Fixed handling of $Conf{BackupFilesOnly} in BackupPC::Xfer::Tar.pm, as
725 well as shell escaping of tar arguments.
727 * Fixed entity encoding of 8-bit characters in the CGI interface.
729 * Added optional CGI headers in $Conf{CgiHeaders} that by default
730 is set to a no-cache pragma. Suggested by Benno Zuure.
732 #------------------------------------------------------------------------
733 # Version 1.4.0, 16 Mar 2002
734 #------------------------------------------------------------------------
736 * BackupPC now supports tar (in addition to smb) for extracting host
737 data. This is the most convenient option for linux/unix hosts.
738 Tar can be configured to run over ssh, rsh or to backup a local
739 nfs mount from the host.
741 * Support for special files, including symbolic links, fifo, character
742 and block device files has been added, so that all native linux/unix
743 file types can be correctly backed up when using tar transport.
744 Special files are all stored as regular files and the type attributes
745 are used to remember the original file type.
747 * All unix file attributes are now saved (and pooled when possible).
748 This includes user and group ownership, permissions, and modification
749 time. Smbclient also does a reasonable job of emulating unix
750 permissions (such as mtime), and these attributes get saved too.
752 * The new default is to not fill incremental dumps. configure.pl
753 automatically sets $Conf{IncrFill} to 0. The default was 1
754 (incrementals were filled with hardlinks). Since the CGI
755 script does filling at browsing time, there is no need to
756 fill incremental dumps.
758 * Backup file names are now stored in "mangled" form. Each node of a
759 path is preceded by "f", and special characters (\n, \r, % and /) are
760 URI-encoded as "%xx", where xx is the ascii character's hex value. So
761 c:/craig/example.txt is now stored as fc/fcraig/fexample.txt. This
762 was done mainly so meta-data could be stored alongside the backup
763 files without name collisions. In particular, the attributes for the
764 files in a directory are stored in a file called "attrib", and
765 mangling avoids file name collisions (I discarded the idea of having
766 a duplicate directory tree for every backup just to store the
767 attributes). Other meta-data (eg: rsync checksums) could be stored in
768 file names preceded by, eg, "c". There are two other benefits to
769 mangling: the share name might contain "/" (eg: "/home/craig" for tar
770 transport), and I wanted that represented as a single level in the
771 storage tree. Secondly, as files are written to NewFileList for later
772 processing by BackupPC_link, embedded newlines in the file's path
773 will cause problems which are avoided by mangling.
775 The CGI script undoes the mangling, so it is invisibe to the user.
776 Of course, old (unmangled) backups are still supported by the CGI
779 * Various changes to the CGI interface, BackupPC_Admin:
781 + Added button that allows users to manually start a full dump in
782 addition to the existing incremental dump.
784 + Added display of file attributes when browsing backups.
786 + Added an optional holdoff time specified by the user when canceling
787 a backup. BackupPC will not attempt any new backups for at least the
788 specified time. This holdoff time can be changed whether or not a
791 + Added supports for file mangling, and correct merging of unfilled
792 backups from mangled or unmangled (and compressed or uncompressed)
793 fulls when browsing or restoring.
795 + Only displays a "Start Incr Backup" button if there are already some
798 + For DHCP hosts, when a user tries to manually start a backup, add
799 a check for the netbios name of both the host the request came
800 from (REMOTE_ADDR) and the last known DHCP address for that host
801 to see if either address matches the host. If not, an error
802 message is display. The previous behavior was that only requests
803 from the client itself succeeded, and requests from other machines
806 * Changed the version numbering to X.Y.Z, instead of X.0Y. This release
807 is 1.4.0. The first digit is for major new releases, the middle digit
808 is for significant feature releases and improvements, and the last
809 digit is for bug fixes. You should think of the old 1.00, 1.01, 1.02
810 and 1.03 as 1.0.0, ..., 1.3.0.
812 * BackupPC and the CGI script BackupPC_Admin now check that the effective
813 user id is correct to avoid accidentally launching BackupPC as the
814 wrong user or detecting CGI configuration problems. This behavior
815 can be turned off using the $Conf{BackupPCUserVerify} option.
817 * In numerous places changed "Smb" to "Xfer" (eg: log file names) to
818 support generic names for both smb and tar transport methods. The
819 CGI script checks for old names for backward compatibility.
821 * Major changed to Backup_dump to support new tar transport. All transport
822 specific code moved into BackupPC::Xfer::Smb and BackupPC::Xfer::Tar
825 * Added workaround for a bug in Samba's smbclient for files between 2GB
826 and 4GB. The file size in the tar header is incorrect. This allows
827 files up to 4GB to work with smbclient, rather than 2GB. To support
828 files larger than 2GB you must make sure perl is compiled with the
829 uselargefiles option (use "perl -V | egrep largefiles" to check) and
830 the pool directory must be on a file system that supports large files.
832 * Moved the pool writing code into a module BackupPC::PoolWrite. This
833 allows the clever file pool checking (digest, uncompressing, comparing
834 etc with minimum disk IO) to be used easily in multiple places (eg: it
835 is now used for writing attribute files so they can be pooled).
837 * Changed MD5 to Digest::MD5 to avoid use of the depreceated MD5 module.
839 * Shortened default $Conf{MyPath} so that perl's taint mode is more likely
840 to be happy. The old $Conf{MyPath} contained /usr/local/bin, which
841 on one user's machine was world writable and perl -T correctly
844 * Fixed ping command options in Lib.pm so that it works on OpenBSD.
845 Thanks to Kyle Amon for sending the fix. Decided to move the
846 ping options from Lib.pm into config.pl (as $Conf{PingArgs}) and
847 now configure.pl tries to come up with a sensible default based on
850 * Fixed argument checking in BackupPC_tarExtract to allow '$' in the
851 share name (eg: C$). Thanks to Jules Agee for this fix. Also
852 changed the default config.pl so that single quotes are used
853 everywhere so that people don't get tripped up putting '$' inside
854 double-quoted strings.
856 #------------------------------------------------------------------------
857 # Version 1.03, 9 Dec 2001
858 #------------------------------------------------------------------------
860 * BackupPC now has full support for compression. There are now two
861 pool areas, the original pool for uncompressed files, and cpool for
862 compressed files. The compression is done by Compress::Zlib.
863 Compression reduces the pool disk usage by around 40%, although your
864 mileage may vary. Compression is optional and can also be specified on
865 a per-PC basis (although this will cost more pool storage since many
866 backup files will have to be stored in both compressed and
869 * A new script, BackupPC_compressPool, can be run to compress the entire
870 pool. This is used once to migrate all the pool data from uncompressed
871 to compressed on existing installations. Read the documentation
872 (Installing BackupPC/Compressing an existing pool) before running
873 BackupPC_compressPool!
875 Alternatively, compression can simply be turned on and all new backups
876 will be compressed. Both old (uncompressed) and new (compressed)
877 backups can be browsed and viewed. Eventually, the old backups will
878 expire and all the pool data will be compressed. However, until the
879 old backups expire, this approach could require 60% or more additional
880 pool storage space to store both uncompressed and compressed versions
883 * Significant improvements to the cgi interface, BackupPC_Admin:
885 - much better layout navigation
886 - handles compressed backup files and compressed log files
887 - handles unfilled incremental dumps
888 - better backup directory browsing navigation
889 - reports compression statistics
890 - $Conf{CgiDateFormatMMDD} allows you to set date format (MM/DD or DD/MM)
891 - Additional customization with $Conf{CgiHeaderFontType},
892 $Conf{CgiHeaderFontSize}, $Conf{CgiNavBarBgColor}, and
893 $Conf{CgiHeaderBgColor}.
895 * Eliminated BackupPC_queueAll. BackupPC directly reads the hosts
896 file and queues the PCs itself. Like config.pl, BackupPC will
897 re-read the hosts file on each wakeup if its modification time
898 changes, or upon a SIGHUP. This also makes for better behavior
899 when adding a host: if you add hosts, simply send a SIGHUP to
900 BackupPC or wait for the next wakeup.
902 * BackupPC_dump now compresses the SmbLOG file if compression is enabled.
904 * BackupPC_dump keeps track of compressed file sizes so that compression
905 statistics can be reported by the cgi interface.
907 * Aging of old log files now handles compressed log files (.z extension).
909 * Added configuration option $Conf{IncrFill} to specify whether
910 incremental dumps should be filled in. Old behavior was that
911 filling was on. Now it's optional. See config.pl for more
914 * BackupPC_nightly now cleans and generates statistics for both
915 the uncompressed pool and compressed pool (cpool).
917 * Added new utility script BackupPC_zcat that can be used to
918 uncompresses BackupPC files.
920 * configure.pl offers various options related to compression,
921 depending upon whether this is a new install or upgrade,
922 and whether or not Compress::Zlib is installed.
924 * configure.pl now makes a backup copy of config.pl before
925 config.pl is updated.
927 * added three new fields to the backups file to handle optional
928 filling and compression stats.
930 * Added -e option to BackupPC_dump. BackupPC now invokes BackupPC_dump -e
931 on each dhcp host once each night to verify that very old backups are
932 expired. This ensures that very old backups are expired even if
933 the dhcp host has not been on the network for a long time.
935 * fixed bug in BackupPC::FileZIO.pm that required Compress::Zlib,
936 even if compression was off. Thanks to Steve Holmes for reporting
939 * fixed bug that caused a BackupPC queue to get blocked when a backup
940 cancel attempt was made during the BackupPC_link phase.
942 #------------------------------------------------------------------------
943 # Version 1.02, 28 Oct 2001.
944 #------------------------------------------------------------------------
946 * Added new script BackupPC_tarExtract to extract the smbclient tar
947 archive. This reduces disk writes by perhaps 90-95% and disk reads by
948 50%. Previously, tar was used to extract and write everything to disk.
949 Then BackupPC_dump would read enough of each file to compute the MD5
950 digest, and then compare the full file with candidate pool files. So
951 for each 1MB file that matches a single file in the pool, there would
952 be 1MB of disk writes and 2MB of disk reads (to compare two 1MB files).
954 BackupPC_tarExtract instead extracts the archive using a 1MB memory
955 buffer. This allows the MD5 digest to be computed without touching the
956 disk. Next, any potential pool file compares are done by comparing the
957 pool file against the incoming tar data in memory, which only requires
958 the pool file to be read. So for each 1MB file that matches a single
959 file in the pool, there are now no disk writes, and only 1MB of reads.
960 BackupPC_tarExtract handles arbitrary size files and repeated
961 potential pool matches. If the incoming file doesn't match the pool
962 then it is written to disk (once the pool is mature this happens maybe
965 * Substantial changes to BackupPC_dump:
967 + BackupPC_tarExtract is now used in place of tar.
969 + BackupPC_dump now reads the output from both smbclient and
970 BackupPC_tarExtract and merges them into SmbLOG.
972 + Named pipes are no longer used to connect smbclient to tar
973 (now BackupPC_tarExtract). Regular pipes are used instead.
974 This avoids the need to system mknod or mkfifo.
976 + Locked files on the client that can't be read by smbclient
977 previously were filled with 0x0 bytes by smbclient, meaning
978 tar extracted a useless file filled with 0x0 bytes. Now,
979 BackupPC_dump watches the output of smbclient and removes
980 any files that smbclient couldn't read. This avoids storing
981 useless files. It tries to replace such files with a hard link
982 to a previous dump. These actions appear in the log file.
984 * added new module lib/BackupPC/FileZIO.pm. This handles pool file
985 I/O and is used by BackupPC_tarExtract. BackupPC::FileIO supports
986 reading and writing compressed and regular files and provides all the
987 hooks for compression support in BackupPC (should be supported in next
988 version). BackupPC::FileIO also does efficient writing of files that
989 contain leading 0x0 bytes (by seeking past the 0x0 bytes). This is
990 helpful when smbclient reads a locked file, and it fills the tar
991 output with a file of the correct size but all 0x0. Such files will be
992 later removed by BackupPC_dump. But in the meantime, BackupPC::FileIO
993 writes such files efficiently (as sparse files), meaning just a few
994 blocks of disk space will be needed even if the file is large.
996 * alive/dead counting for blackout now works correctly for DHCP hosts.
998 * BackupPC resets activeJob on startup, to fix bug when BackupPC was
999 killed and restarted with backups running.
1001 * added extra non blocking select() in BackupPC to make sure the socket
1004 * BackupPC avoids queuing multiple BackupPC_queueAll's on the CmdQueue.
1006 * Updated BackupPC_sendEmail to correctly parse the locked file
1007 error from 2.2.1a smbclient, so that missing Outlook file emails
1008 can be correctly sent.
1010 * Changed HostInfoRead() in lib/BackupPC/Lib.pm to lowercase the
1011 hostname read from the hosts file.
1013 * BackupPC_Admin provides general summary when the host name is empty.
1015 * configure.pl (and BackupPC) now requires perl 5.6.0 or later.
1017 * configure.pl complains if BackupPC is already running, reminding you
1018 to stop it before upgrading.
1020 * updated documentation, and fixed auto-insertion of config.pl into
1021 BackupPC.pod (previously the last config parameter was left out of
1024 #------------------------------------------------------------------------
1025 # Version 1.01, 30 Sep 2001
1026 #------------------------------------------------------------------------
1028 * Documentation cleanup in README, doc/BackupPC.pod, conf/config.pl.
1030 * BackupPC_sendMail now reads the optional per-PC config file, allowing
1031 email configuration parameters to be set on a per-PC basis.
1033 * Removed the unused 4096-length MD5 digest code in lib/BackupPC/Lib.pm.
1035 #------------------------------------------------------------------------
1036 # Version 1.00, 21 Sep 2001
1037 #------------------------------------------------------------------------
1039 * Initial release of BackupPC on sourceforge.net.
