Linux系统备份源代码 可基于用户自定义策略实现系统、应用数据备份

  (f.ex. when run from the development dir and such things..)
- Fixed bad reporting when bad permissions prevented lock
  creation.
- Cleaned up, improved and renamed the (former) 'Log()' function.
  Now called 'log()'. Now takes printf-like formatstring and varargs.
- Fixed bug that got crashed sitback on looping symlinks..
  An error is reported, but the backup is aborted...
- Added printf-like formatting to UI__Warning.
- Bad files (fifo's, bad symlinks etc. are excluded from
  the archive, without sitback halting with an error.
- Fixed incorrect path when checking for Gnu Tar..
  (set Tar path to '/user/bin/tar' if found /usr/bin/tar.
- Added the '-g' switch to allow one to turn on debugging
  at runtime.
- Fixed installation in new Makefiles (due to re-creation of
  Kdevelop projekt file for Kdevelop 1.4). All files now gets
  installed (the right place).
- Major cleanup in archive.cpp, removed lot's of redundant code.
  Replace all the '__execute_tar_get_XXXarchiveid()' functions
  with the new 'Execute()' function in util.c
- Rewrote '__exec_tar_backup()' and '__exec_tar_verify()' to use the
  new 'Execute()' function in util.c
- Replaced all the '__execute_mt_[rewind|format|retension]()' functions
  by calls to the new 'Execute()' function in util.c
- Now writing on the screen that it is waiting until a specific
  day and time, before the backup will run. (when not a daemon, but
  having a 'TIME=' entry in the script or on the command line
- Added the '-b' option. Includes special files into the archive.
  (Also supported as the script keyword 'INCLUDE SPECIAL FILES')
- Fixed problem where tar would hang when searching an archive id
  on a device without any prior archives written to it...!!
- Fixed bug which prevented sitback from determining it's location
  when executed along the PATH
- Compression is disabled if the requested tool is not available
- Checking for 'ps' when initializing.
- Only printing default compression tool to the log if compression
  is enabled
- Added switch '-f' to disable the ncurses based interface
- Solved problem with killing tar while it was running..


0.2.1     20010731
-------------------
- Added options for running a script or a command
  before and after backup.
- Fixed small bug that prevented the user from selecting
  'compress' as compression tool from the command line


0.2.2     20011122
------------------
- Changed from c++ (back) to c during rebuild of
  source tree (Kdevelop crached the old project)
- Remote devices is supported
- Ouups...  seems that archive verification would always
  fail with bzip2 compressed archive on raw devices since
  the detection of the 'trailing garbage. Ignored' messages
  was missing..  Nobody out there using bzip2 ??  Well.
  i fixed it anyway...
- Added a waitpid() loop after backup to make sure
  zombies from the subprocesses is properly terminated
- Returning without any action from the UI__* functions
  if we are running as a daemon
- Added log message when waiting, before starting a backup
- Fixed 2 non-standard #include's of wait.h, now using
  sys/wait.h
- Fixed a misplaced output from OldArchiveid() which
  prevented proper extraction of an old archive id in
  certain cases...
- Fixed bug that made sitback fail in GetBaseDir() when
  executing with a full path, without leading '..'
- Replace a 'WUNTRACED' with zero options mask in two
  waitpid()'s for __execute_tar_backup() and
  __execute_tar_verify()
- Still has a mysterious hang after verification of
  a compressed archive on a remote device..  Perhaps
  a signal that goes missing...  Must add a safety valve..
- Fixed some bugs related to remote devices..
- Added the '-x' and 'EXCLUDE' switch/keyword to allow
  one to specify files/directorys to exclude from the
  backup.
- Added brief description of how to use a remote device
- Added nice-level adjustment
- Changed the output format a bit when tracking output
  from backup/verify of before/after commands
- Fixed bug that would split locations with blank spaces
  before given to tar..   '/tmp/test dir' would be
  '/tmp/test' and 'dir' causing all kinds of errors..
- Added error checking in init(), will translate name
  of executable, if sitback is executed via a symlink
- Fixed detection of local username (suid is supported)
  for remote device operation
- Backup/verify on remote device working with tar.. mt still
  not fixed for remote devices
- RSH given on command line or in script was ignored by
  the OldArchiveId function..
- Resolved the (until now) mysterious hang when using
  remote devices. Forgot to wait on a pid in ArchiveReady.
- All issues relating to remote devices should be resolved.
- Changed location of files..  All files are now kept in
  a local '.sitback' directory. This should solve all
  the problems with users running sitback as a non-root user..
- Removed the basedir detection code, added the homedir
  detection code..  getpwuid() failes without any
  reasonable explanation, so a homebrewed version is used
  untill that issue is under control..
- Html documentation is installed under ${prefix}/doc/sitback
- Error is reported and app. is terminated if there is an
  error during the 'before' or 'after' commands.
- Cosmetic improvements here and there..
- Error is reported if a location given in the script is
  not found or accessible
- Slight improvement of the tracker function (files being
  backed up, written to archivelist, verified etc.)
- Log is quiet about comment lines in scripts (lines beginning
  with the standard '#' sign)
- Processing is stopped with an error if there is an unknown
  directive in the script
- Processing is stopped with an error if a specific compression
  tool is requested and it is not available.
- Fixed bug when testing for bzip2/bunzip2. Now correctly
  detected
- Fixed bug when testing for compress. Now correctly
  detected
- Writes the name of the script on the screen (cosmetic fix).
- (re)Enabled verification of multivolume archives.
- Slight change to startmark generator, in rare cases,
  the startmark filename was illegal.
- Finally got a working detection of looping symlinks..
- Fixed inclusion/exclusion of special files.. Character and
  block device files are also excluded now, unless special
  file inclusion is enabled.
- Fixed the message after pressing ENTER when verifying
  multiple volume archives.
- Config option for following symlinks
- Fixed message when a target that does not exist is listed
  in the script.
- Fixed a small bug that would crash sitback when testing symlinks
- Small change when trying to extract the old archiveid, first,
  the archive is assumed to have the same type as the new one,
  described by the script, if that fails, all other types
  of archives is tested..  (This dramatically decreases the
  time to extract an old archiveid from many archives).


0.2.3     20011126
------------------
- If doing 'sitback --version', the lockfile was
  not removed.. Fixed
- Testing if 'rmt' exists on the remote server
  if the device or file is remote.
- Found/Fixed old stupid-bug in the Execute() function.
- Cosmetic change to output in the progress window.
  (nicer 'filer-is-too-long' indication)
- Cosmetic changes in error reports from verify
- Added the 'LAZY' verify option


0.2.4     20020205
------------------
- Fixed a bug that prevented backup of '/'


0.3.0     20020417
------------------
- Added 'filecopy' backup.
- Changed switch to enter verbose mode (now '--verbose'
- Small fix in the 'looping symlink' detection, cases where
  a looping symlink were located below another symlink would
  go undetected, instead causing all sorts of noise and coredumps.
- Iso files can be created with the TYPE=ISO keyword.
- Added appropriate checks for 'cdrecord' and 'mkisofs' to
  the initialization code.
- Fixed a small issue in the stdout tracker..
- Added cdr/cdrw support...
- Improved the manual section relevant for cd-writing, slightly.
- Added script options for setting the cdrecord fifo size and
  ejecting the cd after writing has completed.
- Fixed a pure cosmetic bug, the day/hour/minute of the
  next time the backup will run was garbage, now
  returns the proper string to output.
- Added support for cdr/cdrw tar archives..
- Fixed a serious bug that would make sitback hang while
  testing for 'compress' on some systems.. (some
  versions of 'compress' does not exit after
  displaying version with the -V switch)
- Tar archives in iso files (and hence, cd's)
  is given a more suitable name depending on
  the type of archive..
- Fixed a few typo's, and improved a bit on the
  manual.
- Improved the report output a bit, now also the result
  of the before and after script is included in the report
- Fixed a problem with a trailing blankspace in the iso code.
- Hmmm.. multiple backup's with a fixed size seemed to be
  broken, but it was not...  tar was broken!!..
  Tar 1.13 has a bug that makes it barf on the -L switch..
  Included a check for this tar version, and a warning
  if the user attempts to create fixed size archives with it..
- Expected tracksize is calculated before recording a cd
  (with mkisofs -print-size ...). The result is used
  as an argument to cdrecord. (Thanks Chris for pointing this one out..)
- Error codes from sitback is now (also) listed in the manual.
- Got cdrecord to work with the tracksize argument.. :)
- Got the alternative temp. dir option working..
- Better handling of errors when mkisofs is failing due to
  bad joliet names..
- Fixed usage of volume names with blankspaces for iso based operations.
- Fixed the reportmail option. (problem with systems not reporting
  a valid domainname)
- Added an option for unattended run. F.ex. for running sitback as part
  of a script.
- Corrected the manual a few places.
- Changed option 'MULTIPLE=[Y|N]' to 'MULTIPLE VOLUMES'
- Fixed a problem with bad symlinks not ignored when doing iso/cdr/cdrw backup
  even though the option IGNORE BAD SYMLINKS was used.


0.3.1     20021201
------------------
- Fixed a problem with test for 'compress' that would
  sometime hang sitback
- Fixed a bug with running unattended in non-ncurses mode
- Made a few changes to the test script
- Made a slight change to the test for 'bzip2', because some older versions
  of bzip2 returns an incorrect error code when run with '--help'

- More changes to mail sending
- Added script option 'INCREMENTAL'.
- Added compression tool 'zip' to the options.
- Added the possibility for skipping use of the lock file.
- Fixed broken verify (Not working when using alternative temp. dir)
- Fixed broken message when waiting for next time condition,
  bug had no influence on the schedule, but was confusing.
- Added new option 'ADD TO ROOT' to allow creation of cd's
  with content added direct to the root-directory of the cd
- Added new option 'NO INFO' to skip inclusion of the
  sitback.* files in the archive, when creating
  plain iso/cd archives.
- Converting blankspaces in the archive name to underscores
- New types added. ZIP,ZIPISO,ZIPCDR,ZIPCDRW
- Improved the stdout/stderr tracker to provide better feedback from
  the operations..
- Fixed a problem with multiple volumes, where the
  archiving would sometime freeze due to chunks
  of garbage (\0) output from tar into the redirected
  stderr file...
- Fixed a bug that would cause sitback to hang after
  printing a report via smb.
- Fixed a bug that prevented proper detection of magnetic tapes.
- Fixed a bug that would leave some types of cd backup not-fixated.


0.3.2     20030421
------------------
- Fixed a bug that would stop the parsing of the script after
  the ID keyword
- Added support for symbolic constants in the reportfile name.

0.3.3     20031010
------------------

  checking for a running thread, in the case where this thread
  had not been started..

0.3.4     20033110
------------------
- Changed the SendMail function. Now uses gethostent() to get
  the correct hostname.
- Fixed a bug in the SendMail function. Using the full hostname
  in the 'MAIL FROM' command made the transfer fail for some MTA's
- Minor cosmetic changes to the subject line for report mails.

------------------
- Implemented smtp authentication.
- Added 'Date:' field to report mails.
- If there are errors during the backup, or with the 'before' or

- When the 'before' or 'after' commands has errors. The output
  is included in the report.

0.3.5p1   20033112
------------------
- Woups!!.. Wrong placement of a 'break'. Now daemon mode should
  run as usual (again).

0.3.5p2   20040301
------------------
- Slight bug in the mail-sending code fixed.. Also,
  reportfiles are now dos-formatted (\r\n), since most
  of the time, those reports are inspected from a Windows
  platform...

0.3.5p3   20042301
------------------
- Fixed bug with mail-sending..  Message body contained standalone
  linefeeds, violating the standard.
- Now using stat64 (if available) to allow for large files (larger than 2GB)
  in the backup.
