21 # Version __VERSION__, __RELEASEDATE__
22 #------------------------------------------------------------------------
24 * Added new script BackupPC_archiveStart that allows command-line
25 starting of archives. Based on script written by Sergey Kovzik,
26 which in turn was based on an earlier version by Holger Parplies.
28 * Added Simplified Chinese CGI translation from Youlin Feng,
29 plus fixed a couple of cases where utf8 share names were
30 not displayed correctly.
32 * Added sorting by column feature to host summary table in CGI
33 interface. Implemented by Jeremy Tietsort.
35 * Added optional support for IO::Dirent which allows inode information
36 to be extracted from the dirent directory structure. This allows
37 BackupPC to order some directory operations by inode, which on
38 some file systems (eg: ext3) can results in a 20-30% performance
39 gain. On other file systems there is no real improvement. This
40 optimization is turned on automatically if IO::Dirent is installed.
42 * Added some performance improvements to BackupPC::Xfer::RsyncFileIO
43 for the case of small files with cached checksums.
45 * Added check to BackupPC at startup that $TopDir can support
46 hardlinks. Also added check to BackupPC_dump that a hardlink
47 below $TopDir/pc/HOST can be made to below $TopDir/cpool.
48 Also added the need for a hard-link capable file system to
49 the documentation. Suggested by Nils Breunese.
51 * Added FreeBSD init.d file provided by Gabriel Rossetti.
53 * Added -l and -L options to BackupPC_tarCreate so that
54 provide a file list (without creating the archive).
57 * Made the default charset for BackupPC_zipCreate cp1252, which
58 appears to work correctly with WinZip. Unfortunately there is
59 no clear standard for charset encoding in zip files.
61 * Added support so that pre-3.0 backups with non-utf8 charsets
62 can be viewed and restored correctly. A new config variable
63 $Conf{ClientCharsetLegacy} specifies the charset used to
64 encode file names in legacy backups. This is only relevant
65 if you are trying to view or restore a backup made with
66 BackupPC 2.x and some of the file names have non-ascii
69 * Added setting of the environment variable BPC_REQUSER to
70 the requesting user name in BackupPC prior to fork(), so
71 each child process inherits the value. Submitted by
74 * Fixed bug in rsync incrementals that happens on particular
75 file names when a file being backed up fails in both rsync
76 phases. Reported by Dan Smisko.
78 * Fixed single-restore file name charsets for IE, reported by
81 * Fixed makeDist so that the --config-dir option to configure.pl
82 works correctly. Reported by Randy Barlow, Tony Shadwick and others.
84 * Removed ConfDir from config editor (since it is hardcoded in
85 lib/BackupPC/Lib.pm). Also made TopDir and LogDir only visible
86 if useFHS (for non-FHS they are hardcoded in lib/BackupPC/Lib.pm).
88 * Applied patch from Holger Parplies that fixes cleanup of early abort
91 * Applied small patch from Sergey to lib/BackupPC/Xfer/Tar.pm that makes
92 it ignore "socket ignored" error on incrementals.
94 * Applied small patch from Sergey to bin/BackupPC_archiveHost.
96 * Changed BackupPC_sendEmail so that summary admin email doesn't
97 include errors from hosts that have $Conf{BackupsDisable} set.
98 Reported by James Kyle. Also, per-user email is now disabled
99 when $Conf{BackupsDisable} is set.
101 * Added RsyncdUserName to the config editor. Reported by Vicent Roca Daniel.
103 * $Conf{IncrLevels} is now defaulted if it is not defined.
105 * configure.pl clears $Conf{ParPath} if it doesn't point to a valid
108 * Added freebsd-backuppc init.d script from Gabriel Rossetti.
110 * Added documentation for BackupPC_tarPCCopy, including use of -P option
111 to tar suggested by Daniel Berteaud.
113 * Config editor now removes white space at start of exec path.
114 Reported by Christoph Iwasjuta.
116 * CgiDateFormatMMDD == 2 gives a YYYY-MM-DD format for CGI dates,
119 #------------------------------------------------------------------------
120 # Version 3.0.0, 28 Jan 2007
121 #------------------------------------------------------------------------
123 * BackupPC_sendEmail now correctly sends admin email if backups
124 were skipped because the disk was too full, reported by Dan
127 * BackupPC_Admin now uses $Conf{UmaskMode}, so config.pl files
128 written by the editor have more restrictive permissions.
129 Reported by Tim Massey.
131 * Host summary now shows active backups on disabled hosts,
134 * Fixed host LOG link and LOG list order, reported by Tim Massey.
136 * Moved Encode.pm version check to start of configure.pl so it
137 produces a useful error message if Encode.pm is too old.
139 * Fixed hrefs to configuration documentation to handle changes
140 in the way perl generates the anchors. Reported by Philip
143 * Host name links in LOG files now allow "." in the host name.
144 Reported by Jean-Michel Beuken.
146 * Fixes to lib/BackupPC/Xfer/Tar.pm for tar 1.16: allow 1
147 (ie: 256) as a successful exit status and match "Total
148 bytes read" message for restores. First reported by
149 Torsten Sadowski and debugged by Ralf Gross and Holger
152 #------------------------------------------------------------------------
153 # Version 3.0.0beta3, 3 Dec 2006
154 #------------------------------------------------------------------------
156 * Removed default paths from conf/config.pl so configure.pl will
157 determine the correct ones at install time. Avoids problem of
158 the config editor complaining about bad executable paths the
159 first time you use it.
161 * Changed first byte of compressed files with rsync checksums appended
162 to 0xd7 to allow correct protocol_version >= 27 md4 checksums to be
163 written. Old cached checksum files have a first byte 0xd6 and are
164 now considered to be uncached. They will be automatically updated
165 as needed. This avoids the cached checksum warnings in beta2.
167 * BackupPC_tarPCCopy now handles all file types correctly. Reported
170 * Fixed BackupPC_nightly to finish pending deletes before renaming
173 * Fixes for rsync restore where hardlink is to file outside of the
174 top-level restore directory. Reported by George Avrunin, who helped
177 * Fixes for checksum mismatch on restore for certain file sizes.
178 Reported by George Avrunin and others.
180 * Fix for config.pl writing code to handle multi-line expressions.
181 Reported by David Relson and others.
183 * Fix for CGI editor when deleting hash entries whose keys are
184 non alphanumeric. Report by David Relson and Aaron Ciarlotta.
186 * Two fixes to configure.pl from Andreas Vögele.
188 #------------------------------------------------------------------------
189 # Version 3.0.0beta2, 18 Nov 2006
190 #------------------------------------------------------------------------
192 * Fix for final md4 digest check on rsync transfers >= 512MB when protocol
193 version >= 27 and checksums are not cached. Reported by Garith Dugmore
196 * Config Editor "Save" button is now always visible, but greyed out
197 until there are changes to save.
199 * Config editor allows other tabs to be selected when there is an
200 error, which allows you to fix an error (eg: missing binary) in
201 an exiting config file. Errors are now displayed at the top of
202 the page in addition to next to the erroneous setting.
204 * configure.pl checks version of Encode.pm. Reported by Chris Stone.
206 * Several fixes to bin/BackupPC_fixupBackupSummary from Stian Jordet.
208 * Fixed config.pl editor writing to solve bug with multi-line text
209 strings ending in newline. Reported and root caused by Les Stott
212 * Fixed error recovery case in BackupPC::PoolWrite, reported by
215 * Fixed table width in backup browsing to avoid Firefox layout anomoly,
216 provided by Jono Woodhouse.
218 * CSS file updates from Jono Woodhouse. Prior (v2) version is included
219 as BackupPC_stnd_orig.css in case people prefer the old skin.
221 * More compact host summary, including disabled host indication,
224 * New directory/file/hardlink and symlink image icons from Sean Cameron
225 and Jono Woodhouse, making directory browse more compact.
227 * BackupPC.pid is now world readable, suggested by Casper Thomsen.
229 * Reordered the Server navigation bar links, suggested by David Relson.
231 * Fixed typos in init.d/src/gentoo-backuppc, configure.pl and config.pl
232 reported by David Relson.
234 #------------------------------------------------------------------------
235 # Version 3.0.0beta1, 30 Jul 2006
236 #------------------------------------------------------------------------
238 * Fixed several Xfer charset conversions.
240 * Added some CGI utf8 conversions from Rodrigo Real and Vincent
243 * Rsync transfers now correctly handle file names with \n or \r.
245 * Host name is forced to lower case, to match 2.x.
247 * Fixed LOG file naming in BackupPC_restore and BackupPC_archive.
249 * GFK applied fr.pm corrections from Nicolas Stransky.
251 * Updated init.d/src scripts for FHS (ie: replaced __TOPDIR__/log
252 with __LOGDIR__ and __TOPDIR__/conf with __CONFDIR__). Patch
253 provided by Rodrigo Real.
255 * Added --log-dir and --conf-dir options to configure.pl.
256 Reported by Vincent Fleuranceau.
258 * Updated File::RsyncP version check in configure.pl, reported
259 by Vincent Fleuranceau. Changed File::RsyncP version to 0.64.
261 #------------------------------------------------------------------------
262 # Version 3.0.0beta0, 11 Jul 2006
263 #------------------------------------------------------------------------
265 * Added configuration and host CGI editor.
267 * Added rsync hardlink support. Requires latest version of
270 * Decoupled BackupPC_dump from BackupPC_nightly by making
271 asynchronous file linking/delete robust to race conditions.
272 Now only BackupPC_nightly and BackupPC_link are mutually
273 exclusive so only one runs at a time, and BackupPC_dump and
274 BackupPC_restore can run anytime.
276 * Added support for multi-level incrementals. In the style of dump(1),
277 the level of each incremental can be specified. Each incremental
278 backups up everything since the most recent backup of a lower level
279 (fulls are always level 0). Previous behavior was all incrementals
280 were level 1, meaning they backed up everything since the last full
281 (level 0). Default configuration is all incrementals are level 1.
283 * Server file names are now in utf8 and optional conversion
284 to/from client name charsets can be configured. All CGI pages
285 now use the utf8 charset.
287 * Backup metadata is now additionally saved to pc/HOST/nnn/backupInfo,
288 in addition to pc/HOST/backups. In case pc/HOST/backups gets trashed,
289 then a new script BackupPC_fixupBackupSummary can read the per-backup
290 metadata from pc/HOST/nnn/backupInfo and reconstruct the backups file.
291 Roberto Moreno also pointed out an early error in the CVS version.
293 * Added Storage module and Storage::Text which localizes all the
294 text data file reading/writing (eg: backups, restores, archives
295 and config.pl files). Added read verify after all write
296 operations for robustness. Additional backends (eg: SQL)
297 can be added in the future as new subclasses of the Storage
300 * Added Config module, and Config::Meta that contains meta data
301 about configuration parameters.
303 * Added RSS support from Rich Duzenbury.
305 * Translations of new 3.0 language strings from Guillaume Filion,
306 Reginaldo Ferreira, Ralph Passgang, Lieven Bridts, Guus Houtzager,
309 * Added optional checking of exit status of Dump/Restore/Archive Pre/Post
310 UserCmd, requested by Kiko Jover, Matthias Bertschy and others.
312 * For new installations configure.pl tries to comply with the file
313 system hierarchy standard, which means all the configuration files
314 below /etc/BackupPC and log files go below /var/log/BackupPC.
316 * Added Slackware init.d script from Tony Nelson.
318 * Fixed error reporting when restore/archive fail to write the
319 request file to the client directory.
321 * Applied patch from Marc Prewitt for DumpPreShareCmd and DumpPostShareCmd.
323 * Apply patch from Pete Wenzel to add smbClientPath => $Conf{SmbClientPath}
324 to DumpPreUserCmd etc.
326 * Added Portuguese Brazillian pt_br.pm from Reginaldo Ferreira.
328 * Jean-Michel Beuken reported several bugs in configure.pl in CVS 3.0.0.
330 * Old backup email warnings now ignore partials requested by Samuel Bancal
332 * Applied patch to bin/BackupPC_sendEmail from Marc Prewitt that
333 ignores any file starting with "." in the pc directory when
334 it is generating warnings about old/unused files/directories.
336 * Applied patch from Marc Prewitt to fix host queue order.
338 * Applied Lorenzo Cappelletti's it.pm patch.
340 * Applied Wander Winkelhorst's nl.pm patch.
342 * Applied Alberto Marconi's it.pm patch.
344 * Add NT_STATUS_FILE_LOCK_CONFLICT to pst read error check in
345 BackupPC_sendEmail to fix bug reported by Dale Renton.
347 * Added fixup of $ENV{REMOTE_USER} to lib/BackupPC/CGI/Lib.pm in the
348 case of using mod_authz_ldap; patch submitted by Alain Perrier.
350 * Added env LC_ALL=C to $Conf{TarClientCmd} and $Conf{TarClientRestoreCmd}
351 to avoid locale problems, suggested by Ludovic Drolez.
353 * Changed ping output parsing to pick out average rtt time, based
354 on patch from Ron Bickers.
356 * Removed leading "./" and top-level "./" directory from
357 zip archives generated by BackupPC_zipCreate. Reported
358 by Josh (hecktarzuli).
360 * BackupPC_tarCreate and BackupPC_zipCreate now allow "@"
361 in share names. Reported by Robert Waldner.
363 * NT_STATUS_INSUFF_SERVER_RESOURCES is now a fatal error for
364 smbclient transfers, suggested by Brian Shand.
366 * Changed bin/BackupPC_archiveHost to use /bin/csh instead of
367 /bin/sh. That way any errors in the pipeline are reported
368 via the exit status, instead of just the last.
370 * Added $Conf{EMailHeaders} for additional email headers, requested
371 by Ludovic Gasc. If the Content-Type charset is set to utf8 then
372 the body of the email is sent in utf8 coding.
374 * Made shareName argument regexp checking more general to allow parens.
376 * Added some debian init.d instructions to init.d/README from
379 * Documentation updates from Richard Ames, JP Vossen, Torsten Finke.
381 #------------------------------------------------------------------------
382 # Version 2.1.2pl2, 18 Jun 2006
383 #------------------------------------------------------------------------
385 * In conf/config.pl, changed --devices to -D in $Conf{RsyncArgs}
386 and $Conf{RsyncRestoreArgs} to fix "fileListReceive failed" and
387 "Can't open .../f%2f for empty output" errors with rsync 2.6.7+.
388 Fix proposed by Justin Pessa and Vincent Ho, and confirmed by
391 * Added patch from Michael (mna.news) to ignore "file is unchanged"
392 message from tar 1.15.x during incremental backups.
394 * Fixed creation of .rsrc directories in bin/BackupPC_tarExtract
395 when used with xtar on MacOS. Reported by Samuel Bancal and
396 Matthew Radey, who helped with debugging.
398 * Fixed bug in BackupPC_tarExtract for files >8GB in size whose
399 lengths are multiples of 256. Reported by Jamie Myers and
400 Marko Tukiainen, who both helped debugging the problem.
402 * Fixed bug in lib/BackupPC/Xfer/RsyncFileIO.pm that caused
403 incorrected deleted attributes to be set in directories
404 where one of the files had an rsync phase 1 retry during
405 an incremental. Reported by Tony Nelson.
407 #------------------------------------------------------------------------
408 # Version 2.1.2, 5 Sep 2005
409 #------------------------------------------------------------------------
411 * Fixed simple but serious bug in bin/BackupPC_tarCreate that prevented
412 hardlinks being saved correctly. Debugged by Michael (mna.news)
413 with several other people.
415 * Fixed serious bug in bin/BackupPC_dump reported/debugged by Dan Niles
416 that can happen when multiple full backups are deleted after
417 $Conf{FullKeepCnt} is changed.
419 * Changed lib/BackupPC/CGI/Lib.pm so that link to "$TopDir/conf/$host.pl"
420 is displayed if it exists. Patch from Andreas Vögele.
422 * Applied daemonize patch to bin/BackupPC from:
423 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=301057
425 * It's now a fatal error if $Conf{CompressLevel} is set, but
426 Compress::Zlib is not found. Before $Conf{CompressLevel} was
427 silently set to 0, which made all the backups uncompressed.
428 That meant the user never knew if they forget to install
429 Compress::Zlib but were expecting compression to be on.
431 * Finally increased $Conf{ClientTimeout} to 72000 (20 hours).
433 * Added sleep 1 in restart() function in init.d/src/gentoo-backuppc,
434 suggested by Jon Hood.
436 * Added $DestDir to the path of the CGI image directory in configure.pl.
437 Patch submitted by Andreas Vögele.
439 * Applied extensive patch to French translation from Frederic Lehobey.
441 * Minor change to Dutch language $Lang{Pool_Stat} from Wander Winkelhorst.
443 * Minor change to French language $Lang{EMailOutlookBackupMesg} and
444 $Lang{EMailOutlookBackupSubj} from Ludovic Gasc.
446 #------------------------------------------------------------------------
447 # Version 2.1.1, 13 Mar 2005
448 #------------------------------------------------------------------------
450 * Fixed bug in top-level restore using rsync XferMethod.
451 BackupPC::View was leaving an extra leading "/" at the start
452 of top-level directories, messing up the FileList sort order.
453 Reported and debugged by Gail Edwards.
455 * Added pathCreate() to BackupPC_tarExtract so that new directories
456 are created. Required for xtar on MacOSX since the virtual resource
457 fork directories (.rsrc) are not explicitly included in the tar
458 archive - just the files below .rsrc are.
460 * Changed $host.$bkupNum.tar$fileExt.* to $host.$bkupNum.tar$fileExt*
461 in $parCmd in bin/BackupPC_archiveHost.
463 * Fixed HostSortCompare() in BackupPC to correctly sort hosts so
464 those with the oldest backups get queued first.
466 * Changed test in BackupPC_sendEmail so that directories/files
467 starting with "." in $TopDir/pc are ignored, rather than
470 * Changed BackupPC_sendEmail to include NT_STATUS_FILE_LOCK_CONFLICT
471 in check for bad outlook files.
473 * Ensure that %Status and %StatusHost are empty if requesting
474 status on hosts in lib/BackupPC/CGI/Lib.pm GetStatusInfo().
475 Fixes problem with new hosts under mod_perl.
477 * Added images/icon-hardlink.gif so that hardlinks show file type icon.
479 #------------------------------------------------------------------------
480 # Version 2.1.0pl1, 15 Aug 2004
481 #------------------------------------------------------------------------
483 * Added fix to nl.pm from Lieven Bridts.
485 * Added patch from Tony Nelson to remove $Info{pid} before BackupPC
486 writes the status and shuts down.
488 * Changed BackupPC_nightly so that it doesn't call find() if the
489 directory doesn't exist. This avoids errors in certain versions
490 of perl. Reported by Bernd Rilling.
492 * Fixed BackupPC::CGI::Lib to correctly re-load config.pl for mod_perl.
493 Reported by Tony Nelson and Jimmy Liang.
495 * Explicitly untaint $In{host} in BackupPC::CGI::Lib to fix problem
496 reported by Thomas Tempé.
498 * Added newline to "...skipping because of user requested delay..."
499 log message in BackupPC_dump. Reported by Wayne Scott.
501 * Added read file size error checking to BackupPC_tarCreate.
502 Reported by Brandon Evans.
504 * Added check in BackupPC::Xfer::RsyncFileIO to ensure that when
505 compression is toggled on/off, a compressed backup doesn't link
506 to an uncompressed pool file (and an uncompressed backup doesn't
507 link to a compressed pool file). Reported by Brandon Evans.
509 * Updated documentation with new dirvish URL and a typo from
512 * Fix to BackupPC_sendEmail so that it correctly sends admin emails
513 for hosts that have failed backups. Reported by Simon Kuhn.
515 #------------------------------------------------------------------------
516 # Version 2.1.0, 20 Jun 2004
517 #------------------------------------------------------------------------
519 * Added Dutch translation from Lieven Bridts, with tweaks from
522 * Added PC-specific config file read in CGI/Archive.pm. Patch
525 * Added non-zero exit code to BackupPC_zcat when uncompress fails.
526 Patch from Pete Wenzel.
528 * Cosmetic changes to PC Summary and Log file language strings from
531 * BackupPC::Lib tries to be more careful when renaming the backups
532 file to backups.old. There have been reports of backups being
533 empty, perhaps when the BackupPC data file system fills up.
534 Now backups is not renamed to backups.old if backups is empty.
536 * BackupPC now closes stderr and stdout before renaming and
537 re-opening the log file.
539 * Pre/post backup/restore/archive commands now correctly set
540 "type" to either incr/full/restore/archive, and now cmdType
541 is the type of Pre/post backup/restore/archive command.
543 * BackupPC_archive correctly terminates archive processes on
546 * Updates to BackupPC_stnd.css with absolute font sizes instead
549 * BackupPC_dump now makes sure that the $Conf{FullAgeMax} check
550 also ensures the full backup is older than the maximum age
551 expected from $Conf{FullPeriod}.
553 #------------------------------------------------------------------------
554 # Version 2.1.0beta2pl1, 30 May 2004
555 #------------------------------------------------------------------------
557 * Fixed bug in rsync checksum caching code in BackupPC::Xfer::RsyncDigest.
559 * BackupPC_zipCreate now ensures the earliest mtime is 1/1/1980,
560 since zip file formats don't support earlier dates. Reported
563 * CGI restore via zip and tar now makes sure stderr is ignored
564 when BackupPC_tarCreate and BackupPC_zipCreate are run.
565 Previously any stderr output would get mixed in the archive,
566 corrupting it. Reported by Dan Niles.
568 #------------------------------------------------------------------------
569 # Version 2.1.0beta2, 23 May 2004
570 #------------------------------------------------------------------------
572 * $Conf{BackupFilesOnly} and $Conf{BackupFilesExclude} now apply
573 to every share, rather than just the first, in the case where
574 they are arrays and there are multiple shares. Suggested
577 * On the phase 2 retry pass with rsync, verify the cached checksums
578 if checksum caching is turned on. This will catch the case of
579 cached checksums being incorrectly appended to the compressed
580 pool file. Added new config parameter $Conf{RsyncCsumCacheVerifyProb}
581 so that cached checksums are verified with a selectable probability.
582 Also, increased File::RsyncP version number to 0.51.
584 * configure.pl now supports an optional batch mode. Command-line
585 options are used to specify all the information that configure.pl
586 needs. This is useful for building auto-install packages.
587 Also, configure.pl now includes pod documentation, so you can do
588 "perldoc configure.pl" to see all the command-line options.
589 Suggested, tested and tweaked by Stuart Herbert for possible
592 * At each wakeup, clients are now queued based on how old the most
593 recent backup is. Clients with errors are queued first, with
594 the oldest error times going first. The rest of the clients are
595 queued next, with the clients with the oldest backup going first.
596 Previously the clients were simply queued in alphabetic order.
597 Suggested by Mike Trisko and Tony Nelson.
599 * Added config parameter $Conf{PartialAgeMax} that controls whether
600 partials are saved at all, and if so, whether the partial will be
601 ignored at the next full backup if it is too old.
603 * BackupPC_tarExtract now allows empty archives without reporting
604 an error. Reported by Don Silvia.
606 * Removed Browse Backups link from Nav Bar in Archive Info display.
607 Reported by Ralph PaĂŸgang.
609 * Fixed documentation display for regular users. Reported by Ralph PaĂŸgang.
611 * Status and PC Summary now work for regular users and only show
612 that user's hosts. Server general status information only appears
613 for admins. Suggested by Ralph PaĂŸgang.
615 * Moved the last three navigation-bar links (docs, FAQ and SF) to
616 a new config parameter $Conf{CgiNavBarLinks}. This allows
617 these links to be locally configured. Based on a patch
618 submitted by Ralph PaĂŸgang.
620 * Allow the navigation bar search box to be disabled by
621 setting $Conf{CgiSearchBoxEnable} to 0. Based on a patch
622 submitted by Ralph PaĂŸgang.
624 * Updates to de.pm from Ralph PaĂŸgang.
626 * Made the BackupPC icon a link to the SF BackupPC project page.
628 #------------------------------------------------------------------------
629 # Version 2.1.0beta1, 4 Apr 2004
630 #------------------------------------------------------------------------
632 * The CSS definition has been removed from the config.pl file and
633 is now a separate file, BackupPC_stnd.css. A new config variable,
634 $Conf{CgiCSSFile}, gives the name of the CSS file to use.
635 Suggested by Ender Mathias.
637 * Fixed the filling of the host name select box for admins.
638 The default $Conf{CgiNavBarAdminAllHosts} is now 1.
639 Reported by Doug Lytle.
641 * Cleaned up warning message for restore using rsync when checksum
642 caching is on, but when file didn't have cached checksums.
644 * Fixed BackupPC_archiveHost to support par2 (par2cmdline).
645 Patch submitted by Jaco Bongers and adapted by Josh Marshall.
647 * Improved stat() usage in BackupPC_nightly, plus some other cleanup,
648 giving a significant performance improvement. Patch submitted by
651 * Allow several BackupPC_nightly processes to run in parallel based
652 on new $Conf{BackupPCNightlyJobs} setting. This speeds up the
653 traversal of the pool, reducing the overall run time for
656 * Allow BackupPC_nightly to split the pool traversal across several
657 nightly runs. This improves the running time per night, at the expense
658 of a slight increase in disk storage as unused pool files might not
659 be deleted for a couple of days. Controller by new config setting
660 $Conf{BackupPCNightlyPeriod}.
662 #------------------------------------------------------------------------
663 # Version 2.1.0beta0, 20 Mar 2004
664 #------------------------------------------------------------------------
666 * A failed full dump is now saved as a partial (incomplete) dump,
667 provided it includes some files. This can be used for browsing,
668 restoring etc, and will also form the basis of resuming full
669 dumps. Only one partial is kept, and it is removed as soon
670 as a successful full (or a new partial) is done.
672 * Added support for resuming a full dump for rsync. The partial
673 full is kept, and to resume an incremental is done against the
674 partial, and a full is done for the rest.
676 * Added support for Rsync checksum caching. Rsync checksum are
677 appended to the compressed pool files. This means that block
678 and file checksums do not need to be recomputed on the server
679 when using rsync. Requires a patch to rsync to support fixed
680 checksum seeds. This patch is included in the cygwin-rsyncd
681 release on http://backuppc.sourceforge.net.
683 * Major addition of Archive feature from Josh Marshall. Special
684 clients can be configured to be archive targets (eg: tape drives,
685 CD-R). Any subset of the backup clients can be selected and tar
686 archives are created, optionally compressed and split and written
687 to the output device. Logs are maintained and are browsable.
689 * Major changes from Ryan Kucera to add style sheets to the CGI
690 interface, allowing easy customization. Added new icons and
691 BackupPC logo. Numerous navigation improvements.
693 * Added directory history display to BackupPC_Admin, allowing the
694 user to quickly see which files changed between backups on a
697 * Added exponential expiry option for full dumps. This allows you
700 - how many fulls to keep at intervals of $Conf{FullPeriod}, followed by
701 - how many fulls to keep at intervals of 2 * $Conf{FullPeriod},
702 - how many fulls to keep at intervals of 4 * $Conf{FullPeriod},
703 - how many fulls to keep at intervals of 8 * $Conf{FullPeriod},
704 - how many fulls to keep at intervals of 16 * $Conf{FullPeriod},
706 and so on. This allows you, for example, to keep 4 weekly fulls,
707 followed by 6 fulls every 4 weeks (approx 1 month) and 2 fulls at
708 16 weeks, for roughly 1 year of history. This works by deleting
709 every other full as each expiry boundary is crossed. Suggested
712 * Added Italian language translation it.pm from Lorenzo Cappelletti.
714 * Major updates to language files for new features and tags changes.
715 Updated makeDist to do pedantic consistency checking of language
718 * Addition of administration options from Paul Lukins. Initial
719 page allows server to be started/stopped/reloaded. This still
720 needs some i18n work. Currently the server start/stop is
723 * Split BackupPC_Admin into a set of modules, one for each major action.
724 Each action is now a seperate module in lib/BackupPC/CGI.
726 * Allow the blackout period begin/end to span midnight. Adapted
727 from patch submitted by David Smith.
729 * Allow multiple blackout periods, with new config variable
730 $Conf{BlackoutPeriods} that replaces the old variables
731 $Conf{BlackoutHourBegin}, $Conf{BlackoutHourEnd}, and
732 $Conf{BlackoutWeekDays}. Based on patch submitted by
735 * Disabled alarms after forks to avoid timeouts in children that
736 do not reset their alarm. Prompted by ideas from James Leu.
738 * Added options for block size, buffer size and share wild-card to
739 BackupPC_tarCreate. Also added negative backup number options
740 that are relative to the last (so -1 is the last), suggested by
741 William McKee and Carl Soderstrom.
743 * The "Wrong user" message in BackupPC::Lib now goes to stderr, so that
744 the user is more likely to see the error with BackupPC_tarCreate.
745 Reported by Paul Fox.
747 * Add creation of per-PC directory in BackupPC/CGI/Restore.pm in
748 case it doesn't already exist.
750 * Added -q -x to all ssh commands in conf/config.pl. Suggested by
751 SI Reasoning and Niranjan Ghate.
753 * Changed restore code so that option #1 (direct restore) can be
754 disabled if the restore command is undefined. Disabling direct
755 restore is necessary if the share is read-only. Suggested by
758 * Changed regexp in lib/BackupPC/Smb.pm to allow numbers with both
759 a decimal point or comma for international versions of Samba.
760 Patch submitted by Frank Gard.
762 * Browsing and directory history now sort the files in a
763 case-insensitive manner.
765 * Changed exec() syntax to allow executing commands whose path
768 * BackupPC_dump no longer removes backups if $Conf{FullKeepCnt}
769 is zero or undefined. The protects the existing backups in the
770 case of a bad config.pl file. Suggested by Christian Warden.
772 * Swapped the Server and Hosts sections on the Nav bar. Moved the
773 host search text box to the top of the hosts section. This was
774 done to move the variable-length part of the Nav bar (when all
775 hosts are displayed) to the bottom.
777 * Fixed a bug in tar restore related to how the common prefix path is
778 removed. Now ensure that the common path is at a directory boundary.
779 Reported by Patrick Neuner.
781 * Added --chuid ${USER} to init.d/src/gentoo-backuppc. Suggested by
782 SI Reasoning, Pascal Pochol, Michael Evanoff and others.
784 * Added Suse notes to init.d/README from Bruno Vernay.
786 * Added Apache 2 documentation fix from Michael Tuzi.
788 #------------------------------------------------------------------------
789 # Version 2.0.2, 6 Oct 2003
790 #------------------------------------------------------------------------
792 * Fixed stupid last-minute change in octal size conversion in
795 #-----------------------------------------------------------------------
796 # Version 2.0.1, 5 Oct 2003
797 #------------------------------------------------------------------------
799 * Fixed handling of >= 8GB files in BackupPC_tarExtract and >= 4GB
800 files in BackupPC_tarCreate.
802 * Removed smbclient size repair in BackupPC_tarExtract for files
803 between 2GB and 4GB. This means that BackupPC_tarExtract 2.0.1
804 doesn't behave the same as 2.0.0 for file sizes between 2GB and 4GB
805 extacted using smbclient 2.2.x. If you have problems backing up
806 files whose size is between 2GB and 4GB using smbclient 2.2.x
807 you should upgrade smbclient to 3.0, since it now generates
810 * Replace PingClientPath with PingPath in configure.pl.
812 * Removed -T (taint mode) on binaries installed in configure.pl.
814 * Added support for smbclient from samba version 3.0.0.
816 * Fixed $Conf{HardLinkMax} limit check in BackupPC::Lib; reported
819 * In BackupPC_Admin, default REMOTE_USER to $Conf{BackupPCUser}
820 if it is not defined. This allows the CGI interface to work
821 when AdminUsers = '*'. Reported by Quentin Arce.
823 * For SMB, code that detected files with a read-locked region (eg:
824 outlook .pst files), removed them and then tried to link with an
825 earlier version was broken. This code missed a step of mangling
826 the file names. This is now fixed. Reported by Pierre Bourgin.
828 * A backup of a share that has zero files is now considered
829 fatal. This is used to catch miscellaneous Xfer errors that
830 result in no files being backed up. A new config parameter
831 $Conf{BackupZeroFilesIsFatal} (defaults to 1) and can be set to
832 zero to turn off this check. Suggested by Guillaume Filion.
833 Additional change: this check only applies to a full dump.
835 * SMB: now detect NT_STATUS_ACCESS_DENIED on entire share or BackupFilesOnly
836 (also ERRDOS - ERRnoaccess (Access denied.) for older versions of
837 smbclient.) Suggested by Guillaume Filion.
839 * SMB: now detects "tree connect failed: NT_STATUS_BAD_NETWORK_NAME" and
840 the dump is considered failed.
842 * Rsync: Previously BackupFilesOnly = '/' did --include '/' --exclude '/*',
843 which just included the '/' directory and nothing below. Now it
844 does just --include '/', which should include everything.
847 * Add hostError to DumpPostUserCmd variable substitutions for both dump
850 * Verbose output in Lib.pm goes to STDERR, not STDOUT. This now
851 makes BackupPC_dump -v work better.
853 * Don't allow browsing with ".." in directory in case a user tries
854 to trick BackupPC_Admin into displaying directories outside where
857 * Required File::RsyncP version is now 0.44, since File::RsyncP 0.44
858 fixes large file (>2GB) bugs. Large file bugs reported by Steve
861 #------------------------------------------------------------------------
862 # Version 2.0.0, 14 Jun 2003
863 #------------------------------------------------------------------------
865 * Minor tweaks to disable utf8 on utf8-capable machines (eg: RH8+).
866 Added "no utf8" to all programs, and added binmode() to relevant
869 #------------------------------------------------------------------------
870 # Version 2.0.0beta3, 1 Jun 2003
871 #------------------------------------------------------------------------
873 * Several improvements to restore: cancel now reports the correct
874 message and cleans up correctly.
876 * Rsync with whitespace and wildcard excludes fixed by replacing
877 argList with argList+ in config.pl plus a fix to Lib.pm for
878 shell escaping array arguments.
880 * Fixed rsync restore for character and block special devices
881 (major and minor device numbers weren't correctly restored).
883 * Fixed typo in bin/BackupPC_restore (XferLOG -> RestoreLOG).
885 * (Re)-fixed "Bad command" in log file when restore via tar or zip
886 file download is done.
888 * Added untaint to exec in Lib.pm to avoid tainted errors.
890 * Applied additional tweak to hilight patch from Tim Demarest.
892 * $Conf{CgiAdminUsers} = '*' now allows privileged even with REMOTE_USER
895 * Don't display RsyncdPasswd when displaying config.pl files.
897 * Replace pipe with socketpair in bin/BackupPC_dump and bin/BackupPC_restore,
898 which increases typical buffering from 4K to 16K-64K. This improves the
901 * Add check on $ENV{LANG} setting do configure.pl: if LANG includes utf
902 then a warning is printed.
904 #------------------------------------------------------------------------
905 # Version 2.0.0beta2, 11 May 2003
906 #------------------------------------------------------------------------
908 * Added German translation, provided by Manfred Herrmann.
910 * Fixed large-file problem with rsync, reported by Manfred Herrmann.
912 * Fixed zip and tar file download from CGI under mod_perl. Reported
913 by Pierre Bourgin and Paul Lukins.
915 * Fixed directory browsing and top-level directory browsing in 2.0.0beta0.
916 Reported by several users.
918 * Added -v option to BackupPC_dump for verbose output (useful when
919 you run the command manually). Added messages for all exits.
921 * If nmblookup returns multiple IP addresses, NetBiosHostIPFind()
922 now returns the first IP address that matches the subnet mask.
923 Suggested by Tim Demarest.
925 * Fixed BackupPC::View so the top-level directory is handled correctly.
926 This allows the top-level share/directory to be restored via the
927 CGI interface. Reported by several users.
929 * Fixed RsyncFileIO failures on certain large files by replacing seek()
930 with sysseek(). Reported by Manfred Herrmann.
932 * Added configurable highlighting of PC status in the CGI summary
933 screen; submitted by Tim Demarest.
935 * Fixed command queue CGI display; submitted by Tim Demarest.
937 * BackupPC_trashClean now logs an error if it can't remove all the
938 trash and then goes back to sleep, rather than continually trying.
940 * Moved correct user (uid) check into BackupPC::Lib so that all
941 applications do a user check if $Cong{BackupPCUserVerify} is
942 set. The avoids the risk of manually running BackupPC_dump as
945 * Loss of blackout now applies to "host not found" as well as no ping.
946 Reported by Dale Renton.
948 * "Host not found" is now treated in a similar manner to "no ping".
950 * Added suse-linux init.d script from Leon Letto.
952 * Added Gentoo linux init.d script from Tim Demarest.
954 * Applied additional i18n strings from GFK and the translation team.
956 * Fixed option parsing so that getopts errors are reported and we exit.
958 * Changed reporting of Xfer PIDs so that rsync cancel works correctly.
960 #------------------------------------------------------------------------
961 # Version 2.0.0beta1, 30 Mar 2003
962 #------------------------------------------------------------------------
964 * Added Spanish translation es.pm from Javier Gonzalez.
966 * Fixed CGI browse navigation bug that causes BackupPC_Admin to wedge
967 when directories were selected in a certain order.
969 * Fixed BackupPC::PoolWrite so that it can recover when the initial
970 file size is wrong. This is needed since rsync could write a file
971 whose size is different from the initial size returned in the
972 file list when that file is updated while rsync is running.
974 * Added binmode(STDIN) to BackupPC_tarExtract, suggested by Pat LoPresti
975 to fix a problem a RedHat8 with perl 5.8.0. It's unclear why this
976 helps, but it should be benign. See:
977 http://sourceforge.net/mailarchive/forum.php?thread_id=1853018&forum_id=503
979 #------------------------------------------------------------------------
980 # Version 2.0.0beta0, 23 Feb 2003
981 #------------------------------------------------------------------------
983 * Support for rsync and rsyncd backup and restore. Changes to
984 BackupPC_dump, BackupPC_restore, and new modules BackupPC::Xfer::Rsync
985 and BackupPC::Xfer::RsyncFileIO.
987 * Added internationalization (i18n) code from Xavier Nicollet,
988 with additions from Guillaume Filion. Voila! BackupPC_Admin
989 now supports English and French, and adding more languages is
990 now easy. New config paramater $Conf{Language} sets the language.
992 * Added optional user-defined pre/post dump/restore commands, allowing
993 things like database shutdown/startup for dumps.
995 * Changed the way hosts are found.
997 * Added $Conf{ClientNameAlias}, which allows the name of the physical
998 client machine to be set. This allows several different backup
999 "hosts" to all refer to the same physical machine, which is
1000 convenient if several different types of data need to be backed
1001 up, or if different parameters are needed for different parts of
1004 * Replaced $Conf{PingArgs} with $Conf{PingCmd}, added $Conf{DfCmd},
1005 $Conf{NmbLookupCmd} allowing all these commands to be fully
1006 configured. Also, all commands can also now be fragments of
1009 * Moved all smbclient commands into the config.pl file so the specific
1010 arguments can be customized. New config parameters are
1011 $Conf{SmbClientFullCmd}, $Conf{SmbClientIncrCmd} and
1012 $Conf{SmbClientRestoreCmd}.
1014 * Added new BackupPC::View module that creates views of backups
1015 (handling merging etc). Updated BackupPC_Admin, BackupPC_zipCreate
1016 and BackupPC_tarCreate to use BackupPC::View. This removes lots
1017 of merging and mangling code from the higher-level code.
1019 * Added code from Toby Johnson that allows additional users to be
1020 specified in the hosts file; these users can also view/start/stop
1021 and restore backups for that host. Also added a new config
1022 setting $Conf{CgiNavBarAdminAllHosts} that allows all hosts to
1023 be listed in the left nav bar for admins.
1025 * Added $Conf{HardLinkMax} (default 31999) which sets the limit on
1026 the maximum number of hardlinks per file in the pool. If a file
1027 ever gets to this number of links a new pool file is created to
1028 handle additional links.
1030 * Added $Conf{PerlModuleLoad}, which allows optional additional perl
1031 modules to be loaded.
1033 * Added $Conf{EMailUserDestDomain} and other EMail config settings to
1034 allow language-specific default messages to be overridden.
1036 * Added BPC_FTYPE_DELETED to lib/BackupPC/Attrib.pm, allowing deleted
1037 files to be represented in the attrib file correctly.
1039 * Added support for environment variable BPC_SMB_PASSWD, which is the
1040 client's smb password. This overrides the old environment variable
1043 * Added taint cleanup for perl5.8 to lib/BackupPC/Lib.pm.
1045 * Changed $tar_unpack_header format in BackupPC_tarExtract to correctly
1046 handle files with trailing spaces.
1048 * Added catching of SIG_PIPE to BackupPC_dump, and changed catch_signal
1049 to ignore multiple signals of the same type.
1051 * Added reporting of the largest number of hardlinks in the pool to the
1054 * Adding reporting of syntax errors in the per-PC config.pl file.
1056 * Updated BackupPC_sendEmail to handle language-specific email messages.
1058 * Allow client (host) names to contain spaces. Spaces in host names
1059 need to be escaped via "\" in the hosts file. The user of spaces in
1060 host names is discouraged, but they should work. One feature that
1061 doesn't work with host names that contain spaces is the highlighting
1062 of that name in the log file display in the CGI interface. There are
1063 no plans to fix this.
1065 * Renamed $Conf{SmbClientTimeout} to $Conf{ClientTimeout}.
1067 * Fixed all open() calls to use 3 argument form to fix handling of file
1068 names with trailing whitespace. Also fixed CGI interface so these
1069 file names are displayed correctly.
1071 * Fixed new 2.0.0 CGI navigation bug that causes the top-level directory
1072 to have a URL "&share=//boot&dir=" instead of "&share=/boot&dir=/".
1073 Reported by Pascal Schelcher. Fixed similar problem reported by
1076 * Added "PerlTaintCheck On" to the mod_perl section in the docs,
1077 suggested by Tim Demarest.
1079 #------------------------------------------------------------------------
1080 # Version 1.5.0, 2 Aug 2002
1081 #------------------------------------------------------------------------
1083 * Changed conf/config.pl so that $Conf{TarIncrArgs} uses the --newer
1084 option instead of --newer-mtime. Also removed --atime-preserve from
1085 $Conf{TarClientCmd}. This makes the default settings work better
1088 * Fixed configure.pl so it correctly detects a running BackupPC <= v1.4.0
1089 so it can correctly warn the user to stop it before upgrading. Reported
1092 * Added missing ";" to entity escape in EscapeHTML in BackupPC_Admin.
1093 Reported by Guillaume Filion.
1095 * Added LDAP setup to documentation from David Holland.
1097 * Tar.pm now adds a "." to file paths that start with "/", so that all
1098 tar paths are relative. From Ludovic Drolez.
1100 #------------------------------------------------------------------------
1101 # Version 1.5.0beta0, 30 Jun 2002
1102 #------------------------------------------------------------------------
1104 * A full set of restore options is now supported, including direct
1105 restore via smbclient or tar or downloading a zip or tar file.
1107 * Major additions to CGI script to support better directory navigation,
1108 restore features and mod_perl. Also, file downloads from the CGI
1109 interface now correctly preserve the file name and provide the
1110 correct Content-Type for the most common types of files. Improved
1111 directory navigation was contributed by Ryan Kucera.
1113 * New script BackupPC_zipCreate (contributed by Guillaume Filion) is the
1114 zip analog of BackupPC_tarCreate. BackupPC_zipCreate can be used to
1115 create a zip archive of any portion of a backup.
1117 * Substantial additions to BackupPC_tarCreate to support restore,
1118 including modifying path names, handling hardlinks, fixing
1119 support of old backups without attributes (pre-v1.4.0). Plus
1120 BackupPC_tarCreate is now an offical part of the release.
1121 (Lack of support for hardlinks was reported by John Stanley.)
1123 * BackupPC_tarExtract now supports hardlinks and fixed pooling of
1126 * A unix domain socket is now used for communication between the CGI
1127 interface and BackupPC. The original TCP socket is optional. Sockets
1128 are correctly re-initialized if config.pl is updated with new socket
1131 * For improved security messages over the unix or TCP socket are protected
1132 via an MD5 digest based on a shared secret, a sequence number, a time
1133 stamp and a unique per-connection number.
1135 * Additions to configure.pl to support install of directory navigation
1138 * Fixed case where $Conf{BackupFilesOnly} or $Conf{BackupFilesExclude}
1139 were set to a single string or list (in v1.4.0 only the case of
1140 hash worked correctly). Reported by Phillip Bertolus.
1142 * Fixed case of $Conf{BackoutGoodCnt} == 0. This setting now makes the
1143 client always subject to blackout, matching the comments in config.pl.
1144 Also fixed handling of $Conf{BackoutGoodCnt} < 0 in the CGI script
1145 reported by Pascal Schelcher.
1147 * Fixed byte and file totals for tar backups, reported by several users.
1149 * Fixed --newer-mtime date/timestamp format to make it ISO 8601 compliant,
1150 suggested by Erminio Baranzini.
1152 * Fixed handling of $Conf{BackupFilesOnly} in BackupPC::Xfer::Tar.pm, as
1153 well as shell escaping of tar arguments.
1155 * Fixed entity encoding of 8-bit characters in the CGI interface.
1157 * Added optional CGI headers in $Conf{CgiHeaders} that by default
1158 is set to a no-cache pragma. Suggested by Benno Zuure.
1160 #------------------------------------------------------------------------
1161 # Version 1.4.0, 16 Mar 2002
1162 #------------------------------------------------------------------------
1164 * BackupPC now supports tar (in addition to smb) for extracting host
1165 data. This is the most convenient option for linux/unix hosts.
1166 Tar can be configured to run over ssh, rsh or to backup a local
1167 nfs mount from the host.
1169 * Support for special files, including symbolic links, fifo, character
1170 and block device files has been added, so that all native linux/unix
1171 file types can be correctly backed up when using tar transport.
1172 Special files are all stored as regular files and the type attributes
1173 are used to remember the original file type.
1175 * All unix file attributes are now saved (and pooled when possible).
1176 This includes user and group ownership, permissions, and modification
1177 time. Smbclient also does a reasonable job of emulating unix
1178 permissions (such as mtime), and these attributes get saved too.
1180 * The new default is to not fill incremental dumps. configure.pl
1181 automatically sets $Conf{IncrFill} to 0. The default was 1
1182 (incrementals were filled with hardlinks). Since the CGI
1183 script does filling at browsing time, there is no need to
1184 fill incremental dumps.
1186 * Backup file names are now stored in "mangled" form. Each node of a
1187 path is preceded by "f", and special characters (\n, \r, % and /) are
1188 URI-encoded as "%xx", where xx is the ascii character's hex value. So
1189 c:/craig/example.txt is now stored as fc/fcraig/fexample.txt. This
1190 was done mainly so meta-data could be stored alongside the backup
1191 files without name collisions. In particular, the attributes for the
1192 files in a directory are stored in a file called "attrib", and
1193 mangling avoids file name collisions (I discarded the idea of having
1194 a duplicate directory tree for every backup just to store the
1195 attributes). Other meta-data (eg: rsync checksums) could be stored in
1196 file names preceded by, eg, "c". There are two other benefits to
1197 mangling: the share name might contain "/" (eg: "/home/craig" for tar
1198 transport), and I wanted that represented as a single level in the
1199 storage tree. Secondly, as files are written to NewFileList for later
1200 processing by BackupPC_link, embedded newlines in the file's path
1201 will cause problems which are avoided by mangling.
1203 The CGI script undoes the mangling, so it is invisibe to the user.
1204 Of course, old (unmangled) backups are still supported by the CGI
1207 * Various changes to the CGI interface, BackupPC_Admin:
1209 + Added button that allows users to manually start a full dump in
1210 addition to the existing incremental dump.
1212 + Added display of file attributes when browsing backups.
1214 + Added an optional holdoff time specified by the user when canceling
1215 a backup. BackupPC will not attempt any new backups for at least the
1216 specified time. This holdoff time can be changed whether or not a
1219 + Added supports for file mangling, and correct merging of unfilled
1220 backups from mangled or unmangled (and compressed or uncompressed)
1221 fulls when browsing or restoring.
1223 + Only displays a "Start Incr Backup" button if there are already some
1226 + For DHCP hosts, when a user tries to manually start a backup, add
1227 a check for the netbios name of both the host the request came
1228 from (REMOTE_ADDR) and the last known DHCP address for that host
1229 to see if either address matches the host. If not, an error
1230 message is display. The previous behavior was that only requests
1231 from the client itself succeeded, and requests from other machines
1234 * Changed the version numbering to X.Y.Z, instead of X.0Y. This release
1235 is 1.4.0. The first digit is for major new releases, the middle digit
1236 is for significant feature releases and improvements, and the last
1237 digit is for bug fixes. You should think of the old 1.00, 1.01, 1.02
1238 and 1.03 as 1.0.0, ..., 1.3.0.
1240 * BackupPC and the CGI script BackupPC_Admin now check that the effective
1241 user id is correct to avoid accidentally launching BackupPC as the
1242 wrong user or detecting CGI configuration problems. This behavior
1243 can be turned off using the $Conf{BackupPCUserVerify} option.
1245 * In numerous places changed "Smb" to "Xfer" (eg: log file names) to
1246 support generic names for both smb and tar transport methods. The
1247 CGI script checks for old names for backward compatibility.
1249 * Major changed to Backup_dump to support new tar transport. All transport
1250 specific code moved into BackupPC::Xfer::Smb and BackupPC::Xfer::Tar
1253 * Added workaround for a bug in Samba's smbclient for files between 2GB
1254 and 4GB. The file size in the tar header is incorrect. This allows
1255 files up to 4GB to work with smbclient, rather than 2GB. To support
1256 files larger than 2GB you must make sure perl is compiled with the
1257 uselargefiles option (use "perl -V | egrep largefiles" to check) and
1258 the pool directory must be on a file system that supports large files.
1260 * Moved the pool writing code into a module BackupPC::PoolWrite. This
1261 allows the clever file pool checking (digest, uncompressing, comparing
1262 etc with minimum disk IO) to be used easily in multiple places (eg: it
1263 is now used for writing attribute files so they can be pooled).
1265 * Changed MD5 to Digest::MD5 to avoid use of the depreceated MD5 module.
1267 * Shortened default $Conf{MyPath} so that perl's taint mode is more likely
1268 to be happy. The old $Conf{MyPath} contained /usr/local/bin, which
1269 on one user's machine was world writable and perl -T correctly
1270 complained about it.
1272 * Fixed ping command options in Lib.pm so that it works on OpenBSD.
1273 Thanks to Kyle Amon for sending the fix. Decided to move the
1274 ping options from Lib.pm into config.pl (as $Conf{PingArgs}) and
1275 now configure.pl tries to come up with a sensible default based on
1278 * Fixed argument checking in BackupPC_tarExtract to allow '$' in the
1279 share name (eg: C$). Thanks to Jules Agee for this fix. Also
1280 changed the default config.pl so that single quotes are used
1281 everywhere so that people don't get tripped up putting '$' inside
1282 double-quoted strings.
1284 #------------------------------------------------------------------------
1285 # Version 1.03, 9 Dec 2001
1286 #------------------------------------------------------------------------
1288 * BackupPC now has full support for compression. There are now two
1289 pool areas, the original pool for uncompressed files, and cpool for
1290 compressed files. The compression is done by Compress::Zlib.
1291 Compression reduces the pool disk usage by around 40%, although your
1292 mileage may vary. Compression is optional and can also be specified on
1293 a per-PC basis (although this will cost more pool storage since many
1294 backup files will have to be stored in both compressed and
1297 * A new script, BackupPC_compressPool, can be run to compress the entire
1298 pool. This is used once to migrate all the pool data from uncompressed
1299 to compressed on existing installations. Read the documentation
1300 (Installing BackupPC/Compressing an existing pool) before running
1301 BackupPC_compressPool!
1303 Alternatively, compression can simply be turned on and all new backups
1304 will be compressed. Both old (uncompressed) and new (compressed)
1305 backups can be browsed and viewed. Eventually, the old backups will
1306 expire and all the pool data will be compressed. However, until the
1307 old backups expire, this approach could require 60% or more additional
1308 pool storage space to store both uncompressed and compressed versions
1309 of the backup files.
1311 * Significant improvements to the cgi interface, BackupPC_Admin:
1313 - much better layout navigation
1314 - handles compressed backup files and compressed log files
1315 - handles unfilled incremental dumps
1316 - better backup directory browsing navigation
1317 - reports compression statistics
1318 - $Conf{CgiDateFormatMMDD} allows you to set date format (MM/DD or DD/MM)
1319 - Additional customization with $Conf{CgiHeaderFontType},
1320 $Conf{CgiHeaderFontSize}, $Conf{CgiNavBarBgColor}, and
1321 $Conf{CgiHeaderBgColor}.
1323 * Eliminated BackupPC_queueAll. BackupPC directly reads the hosts
1324 file and queues the PCs itself. Like config.pl, BackupPC will
1325 re-read the hosts file on each wakeup if its modification time
1326 changes, or upon a SIGHUP. This also makes for better behavior
1327 when adding a host: if you add hosts, simply send a SIGHUP to
1328 BackupPC or wait for the next wakeup.
1330 * BackupPC_dump now compresses the SmbLOG file if compression is enabled.
1332 * BackupPC_dump keeps track of compressed file sizes so that compression
1333 statistics can be reported by the cgi interface.
1335 * Aging of old log files now handles compressed log files (.z extension).
1337 * Added configuration option $Conf{IncrFill} to specify whether
1338 incremental dumps should be filled in. Old behavior was that
1339 filling was on. Now it's optional. See config.pl for more
1342 * BackupPC_nightly now cleans and generates statistics for both
1343 the uncompressed pool and compressed pool (cpool).
1345 * Added new utility script BackupPC_zcat that can be used to
1346 uncompresses BackupPC files.
1348 * configure.pl offers various options related to compression,
1349 depending upon whether this is a new install or upgrade,
1350 and whether or not Compress::Zlib is installed.
1352 * configure.pl now makes a backup copy of config.pl before
1353 config.pl is updated.
1355 * added three new fields to the backups file to handle optional
1356 filling and compression stats.
1358 * Added -e option to BackupPC_dump. BackupPC now invokes BackupPC_dump -e
1359 on each dhcp host once each night to verify that very old backups are
1360 expired. This ensures that very old backups are expired even if
1361 the dhcp host has not been on the network for a long time.
1363 * fixed bug in BackupPC::FileZIO.pm that required Compress::Zlib,
1364 even if compression was off. Thanks to Steve Holmes for reporting
1367 * fixed bug that caused a BackupPC queue to get blocked when a backup
1368 cancel attempt was made during the BackupPC_link phase.
1370 #------------------------------------------------------------------------
1371 # Version 1.02, 28 Oct 2001.
1372 #------------------------------------------------------------------------
1374 * Added new script BackupPC_tarExtract to extract the smbclient tar
1375 archive. This reduces disk writes by perhaps 90-95% and disk reads by
1376 50%. Previously, tar was used to extract and write everything to disk.
1377 Then BackupPC_dump would read enough of each file to compute the MD5
1378 digest, and then compare the full file with candidate pool files. So
1379 for each 1MB file that matches a single file in the pool, there would
1380 be 1MB of disk writes and 2MB of disk reads (to compare two 1MB files).
1382 BackupPC_tarExtract instead extracts the archive using a 1MB memory
1383 buffer. This allows the MD5 digest to be computed without touching the
1384 disk. Next, any potential pool file compares are done by comparing the
1385 pool file against the incoming tar data in memory, which only requires
1386 the pool file to be read. So for each 1MB file that matches a single
1387 file in the pool, there are now no disk writes, and only 1MB of reads.
1388 BackupPC_tarExtract handles arbitrary size files and repeated
1389 potential pool matches. If the incoming file doesn't match the pool
1390 then it is written to disk (once the pool is mature this happens maybe
1393 * Substantial changes to BackupPC_dump:
1395 + BackupPC_tarExtract is now used in place of tar.
1397 + BackupPC_dump now reads the output from both smbclient and
1398 BackupPC_tarExtract and merges them into SmbLOG.
1400 + Named pipes are no longer used to connect smbclient to tar
1401 (now BackupPC_tarExtract). Regular pipes are used instead.
1402 This avoids the need to system mknod or mkfifo.
1404 + Locked files on the client that can't be read by smbclient
1405 previously were filled with 0x0 bytes by smbclient, meaning
1406 tar extracted a useless file filled with 0x0 bytes. Now,
1407 BackupPC_dump watches the output of smbclient and removes
1408 any files that smbclient couldn't read. This avoids storing
1409 useless files. It tries to replace such files with a hard link
1410 to a previous dump. These actions appear in the log file.
1412 * added new module lib/BackupPC/FileZIO.pm. This handles pool file
1413 I/O and is used by BackupPC_tarExtract. BackupPC::FileIO supports
1414 reading and writing compressed and regular files and provides all the
1415 hooks for compression support in BackupPC (should be supported in next
1416 version). BackupPC::FileIO also does efficient writing of files that
1417 contain leading 0x0 bytes (by seeking past the 0x0 bytes). This is
1418 helpful when smbclient reads a locked file, and it fills the tar
1419 output with a file of the correct size but all 0x0. Such files will be
1420 later removed by BackupPC_dump. But in the meantime, BackupPC::FileIO
1421 writes such files efficiently (as sparse files), meaning just a few
1422 blocks of disk space will be needed even if the file is large.
1424 * alive/dead counting for blackout now works correctly for DHCP hosts.
1426 * BackupPC resets activeJob on startup, to fix bug when BackupPC was
1427 killed and restarted with backups running.
1429 * added extra non blocking select() in BackupPC to make sure the socket
1432 * BackupPC avoids queuing multiple BackupPC_queueAll's on the CmdQueue.
1434 * Updated BackupPC_sendEmail to correctly parse the locked file
1435 error from 2.2.1a smbclient, so that missing Outlook file emails
1436 can be correctly sent.
1438 * Changed HostInfoRead() in lib/BackupPC/Lib.pm to lowercase the
1439 hostname read from the hosts file.
1441 * BackupPC_Admin provides general summary when the host name is empty.
1443 * configure.pl (and BackupPC) now requires perl 5.6.0 or later.
1445 * configure.pl complains if BackupPC is already running, reminding you
1446 to stop it before upgrading.
1448 * updated documentation, and fixed auto-insertion of config.pl into
1449 BackupPC.pod (previously the last config parameter was left out of
1452 #------------------------------------------------------------------------
1453 # Version 1.01, 30 Sep 2001

1456 * Documentation cleanup in README, doc/BackupPC.pod, conf/config.pl.
1458 * BackupPC_sendMail now reads the optional per-PC config file, allowing
1459 email configuration parameters to be set on a per-PC basis.
1461 * Removed the unused 4096-length MD5 digest code in lib/BackupPC/Lib.pm.
