- Release Notes for Bacula 2.0.0
+ Release Notes for Bacula 2.2.0
Bacula code: Total files = 438 Total lines = 154,329 (*.h *.c *.in)
-==== IMPORTANT Catalog update required =====
-- The database format has been updated from what was used in
- Bacula 1.38.x. You must manually update your database before
- running Bacula 1.39.x or higher. If you are using Bacula supplied
- RPMs this is not necessary as the RPM does it automatically.
- Please backup your previous version of the database before
- running the update. The update script will be automatically
- installed in your scripts directory, or can also be found in
- <bacula-source>/src/cats. It is called:
-
- ./update_bacula_tables
-
- It is necessary to run it only once the first time you move to
- a 2.0.0. Upgrading the Bacula version thereafter does not
- require updating the database again. Depending on the size of
- your database the script make take a bit of time, to run, but
- in general, it should be very fast.
-
-==== IMPORTANT new Win32 install procedure =====
- For Win32 migrations from versions prior to 1.39.0 nothing special
- needs to be done to upgrade. Everything should be taken care of
- automatically. The only thing not done is to delete the old C:\bacula
- directory mostly out of paranoia.
-
-==== IMPORTANT miscellaneous ====
-- The Gnome console program (gconsole) no longer functions as it
- should.More importantly, in restore mode, the restore tree is
- no longer shown in the left pane. I suspect this is due to
- incompatible changes in the GTK+ API, and hence have given up
- on gnome and gtk+, as this has already happened several times
- previously. At some point there will be a new GUI console.
-- The bacula-dir.conf directive Accept Any Volume has been
- removed because it was never implemented. You must delete all
- occurrence of this directive for the Director to run. The Storage
- daemon will automatically accept any valid Volume that you mount.
-- The --mandir ./configure option now points to the top level man
- directory. The man files will be installed under mandir/man8 and
- mandir/man1 as appropriate.
-- You *should* be able to use 1.38.x FDs with version 2.0.0 Director
- and SD providing you do not use any of the new features (runscript,
- data encryption). It seems to work here, but we do not guarantee it.
-- Your Director and SD must be simultaneously upgraded.
-- The restore command no longer uses the MediaType as the primary method
- of finding a suitable Storage device. Normally it will select the last
- device used to write a Volume. If no storage device is defined, it
- will use the old algorithm which selects the first Storage resource
- with the correct MediaType.
-- The MD5/SHA1 hash codes kept in the database are now kept in a binary
- format compatible with the rest of the world. If you are running verify
- jobs, you *must* do an InitCatalog or all files will show an MD5
- difference. Also, authentication uses the new algorithm by
- default, but *should* accept connections from older components (FD) using
- the old non-compatible algorithm. This has been tested, but more
- more testing is still needed.
-- A stock SuSE 10.1 kernel may crash when Bacula runs and accesses
- the tape drive. Workaround, load the SuSE 10.1 version 2.6.16.21-0.25
- kernel or later. The SuSE 10.2 Alpha 5 or later kernel also works.
- This problem may also be present in certain Fedora FC5 kernels.
-- If you have been using the data encryption feature of 1.39.x, please
- be aware that certain combinations of encryption and other options
- with version 1.39.0 through 1.39.26 created Volume data that cannot
- be restored. We strongly recommend that anyone using encryption
- carefully review his/her backups and at a minium do a Full backup
- with 1.39.28 of all encrypted data. Robert Nelson has identified
- and fixed it as follows:
- As of 1.39.27:
- No filters = Works fine
- Sparse = Works fine
- Compression = Works fine
- Encryption = Works fine
- Sparse + Compression = Works fine
-
- Sparse + Encryption = Restore broken
- Sparse + Compression + Encryption = Restore broken
- Compression + Encryption = Restore broken
-
- As of 1.39.28:
- Most combinations work, but some encrypted files are
- not properly restored.
-
- As of 1.39.30:
- All combinations work fine except Sparse+Encryption.
-
- Bottom line, if you are using data encryption, please test restoring
- data to be sure it all works correctly.
-- The current Volume format written by 1.39.22 is different from
- the format written by previous versions. The two formats
- are not compatible. Thus any DVDs written prior to 1.39.22 will
- be unreadable by version 1.39.22.
-- If you previously run a Bacula version prior to 1.39.30, the JobMedia
- data may not be correct for disk Volumes. This can cause incorrect
- seeking in versions after 1.39.30. If you experience what appears to
- be data I/O or integrity errors during restores, please add the
- following directive to your disk DEVICE resource in the Storage
- daemon conf file:
-
- Block Positioning = no
-
- This will turn off all seek requests during restores and avoid
- this problem.
-- VSS for Windows clients is now enabled by default.
-- Do not unload autochanger when doing "update slots"
-- Implement mount command for autochanger, see manual.
-
-New Features in 2.0.0:
-- Turn on disk seek code for restores.
-- There is a partial but reasonable translation of the Bacula
- messages for French. To install it, first configure and build
- Bacula, then as root run:
-
- cd <bacula-source>/po
- make install
-
- If you have your locale set properly you will get the translated
- messages.
-- Bacula now support Migration jobs that are documented in a new
- Migration chapter in the manual
- http://www.bacula.org/dev-manual/Migration.html
-- Data encryption is now implemented and is documented in
- a new chapter of the manual at:
- http://www.bacula.org/dev-manual/Bacula_Data_Encryption.html
-- Additional support for removable devices. See the
- Requires Mount, Mount Point, Mount Command, and Unmount
- Commands in the Storage daemon configuration chapter:
- http://www.bacula.org/dev-manual/Storage_Daemon_Configuratio.html
- Also see the Edit Codes for Mount and Unmount Directives in the
- same chapter.
-- Switch the Win32 build from using Microsoft C++ to using mingw32
- cross-compiling. The initial work was done by Howard Thomson,
- then tweaked by me. Robert Nelson then totally reworked the
- cross-compiling code so that it not only cross-compiles, but
- also compiles on Visual Studio, and at the same time, he added
- all the current Unix features to the FD, such as selection on
- drives, encryption support, building *all* the tools, ...
-- The Director and Storage daemon have now been ported to Win32.
- This code is working but should still be tested carefully
- before putting into production.
-- Bacula restore and bextract can now extract non-portable Win32 data to
- any client (including Unix/Linux clients). Of course, in doing so,
- the Microsoft specific permissions and ACLs will be lost. Thanks
- to Thorsten Engel for this code.
-- The 260 character limitation for Win32 paths name lengths is now
- eliminated thanks to Thorsten Engel. However, if you are using
- Volume Shadow Copy, please be careful to specify all the paths
- in the bacula-fd.conf file using a full path notation including
- the drive letter.
-- Eric Bollengier wrote new RunScript directives that includes
- the old RunBefore/AfterJob and ClientRunBefore/AfterJob features
- plus a *lot* more, allowing you to control just about every aspect
- of running scripts. See the manual for detailed documentation.
- http://www.bacula.org/dev-manual/Configuring_Director.html#5227
-- SunOS ACLs should now work thanks to a patch from David Duchscher.
-- Apply days keyword patch from Alexander.Bergolth at wu-wien.ac.at
- If this patch is applied, the number of days can be specified with
- "list nextvol days=xx"
- or
- "status dir days=xx"
- This can be used to preview the next scheduled job (and the
- next tape to be used) on Fridays if there are no scheduled jobs during
- the weekend.
-- From Eric Bollengier. One can now using the bconsole wait command do:
- wait (wait for all jobs to stop)
- wait jobid=nn
- wait jobuid=unique id
- wait job=job-name
-- Volumes can now be set to Enable, Disable, or Archive. If they
- are not enabled, Volumes will not be mounted.
- Implement update volume enable=(on|off|true|false|archived|0|1|2)
-- Add Catalog message destination in Messages resource that puts the
- job report in the Log database table.
-- Writing/reading DVD Volumes is much more stable -- to the point
- of being useful. Thanks to Richard Mortimer.
-- Add enable/disable job=<job-name>. This command prevents
- the specified job from being scheduled. Even when disabled,
- the job can be manually started from the console.
-- The database Id records should be 32/64 bit independent now. 64 bits
- can be enabled by changing one define and changing the appropriate
- table variable. Normally, you need 64 bits only for FileId.
-- Relative path specifications (i.e. ../xxx) are now permitted in
- the restore cd command.
-- When running multiple simultaneous jobs, most jobs that use spooling
- will now finish faster due to a mutex optimization made by Eric
- Bollengier.
-- Conf files containing UTF-8 marker at the head of the file as well as
- conf files containing Window cr/lf and Mac cr line termination characters
- are now accepted thanks to Robert Nelson.
-- Windows tray status windows are scrollable and resizable.
-- Win32 external script execution is much more flexible -- handles
- spaces in names better, ...
-- Lots of DVD fixes -- writing DVDs is now reported to work.
-- Fix opening of database in a restricted console to respect
- any Catalog ACL.
-- Much better automatic handling of multiple database catalogs in
- the restore command.
-- Permit multiple console/director resources in bconsole.conf.
- patch from Carsten Paeth calle@calle.in-berlin.de
-- Character substitution in Job/JobDefs WriteBootStrap.
- from Eric Bollengier.
-- Apply patch supplied in bug #656 to pass priority field
- in the run dialog to the Director in gnome console.
-- Add support of encrypted data stream to bscan from Eric.
- display data_len instead of data content (may be binary).
-- Add Enabled=xxx on update slots command.
-- Add host:port to connect failure messages to FD and SD from Dir/
-- Add WhereACL to console ACL list. If nothing is specified, only
- the default is permitted for restore. Otherwise, *all* allows any
- path, or you can specify permitted paths. This should allow control
- over where users can restore files. This is untested.
-- Install man pages with 'make install'.
-- Add Media.Enabled flag to client backups for dotcmds.c
-- Enforce Media.Enabled=1 for a current restore to work
-- Require restore case 3 to have sqlquery permission to work.
-- Add -n option to bconsole to turn off conio -- used in bweb.
-- The bytes field in the terminated jobs part of the status
- command now reports in KB, MB, ... units.
-- When not descending into a directory, print the File= name that
- triggered it -- makes why not descending a bit clearer
-- Do not unload autochanger when doing "update slots"
-- Implement mount command for autochanger
-- Fix bug #462 incorrect error message printed when client script called
- from File= was not found.
-- Fix bug #558 (waiting for feedback) where Bacula needs too much time to
- do a rewind on Solaris when no tape is in the drive (Solaris does not
- have the detailed errno found on Linux). Added Solaris specific code.
- Note, this may apply to other OSes as well.
-- The examples directory has a new bacula_mail_summary.sh file that
- creates a single email summary of any number of jobs. Submitted by
- Andrew J. Millar.
-- Add nagios plugin to the examples directory. Submitted by
- Christian Masopust.
-- Modify most restore error messages to be queued so that they
- appear at the end of the job rather than mixed with the restore
- listing where they could be "lost".
-- Apply patch supplied by user (slightly modified) to fix
- correct detection of holes in block devices and FIFOs.
- Bug # 506.
-- Added a report.pl program to the examples directory from Jonas Bjorklund.
-- Add two new queries to query.sql provided by Arno. One
- list volumes known to the Storage device, and the other
- lists volumes possibly needing replacement (error, ...).
-- Implement new code for changing userid and group at startup. This
- should get Bacula into the correct groups.
-- Implement support for removable filesystems -- device type directive
- and mount, unmount directives.
-- Transfer rates are now presented in a more readable format thanks
- to a user submission.
-- SD is now aware of what volumes are mounted. More information is printed
- in the Status report. You must take much more care now to unmount
- devices prior to removing tapes that Bacula has open or prior to
- changing a magazine. Don't forget to do a mount afterwards or the
- device will be blocked.
-- The Pool Maximum Volumes directive is now respected in all places.
-- A Storage device can now be specified in a Pool resource. It will override
- all other Storage specifications.
-- Most but not all directives accept true/false in place of yes/no.
-- A patch from Karl Hakimian that reads JobIds, FileIndexes
- from a database table for restore.
-- There are a number of new tables. Some such as the Location table are
- designed for user use in doing Volume Management software.
-- Maximum Changer Wait, Maximum Open Wait, Maximum Rewind Wait to
- accept time qualifiers.
-- Implement jobuid to replace old usage of job in keywords as
- suggested by Eric Bollengier.
-- Implement write variables for Python to set Priority (anytime), and
- Job Level, only during JobInit event.
-- Use the keyword ujobid to mean the unique job id; job or jobname
- to mean the Job name given on the Name directive, and jobid to
- be the numeric (non-unique) job id.
-- Allow the SD to use multiple drives during a backup/restore (only
- one at a time).
-- Integrate addition of line count limitation to bsmtp -l from
- Sebastian Stark <stark at tuebingen.mpg.de>
-- Split the bacula start/start script into four files:
- bacula -- starts and stops calling other scripts
- bacula-ctl-dir -- starts/stops the director
- bacula-ctl-fd -- starts/stops the File daemon
- bacula-ctl-sd -- starts/stops the Storage daemon
-- Remove automatic case folding on Windows FDs. You must
- explicitly use the 'Ignore Case = yes' option.
-- Implement wild program in tools directory for testing
- wild-cards. Almost identical to the regex program.
-- Use the new bregex.c to implement Regex expressions on Win32.
-- Apply patch from Christopher Hull
- - Allow multiple connections to database with different
- parameters.
- - Invalidate the scheduler when doing a reload. Fixes seg
- fault, but still 60 second window.
- - Additional info in Reschedule message.
- - Use set_jcr_job_status() everywhere to prevent loss of
- cancel, error.
- - Display peer IP in FD if error from connecting DIR.
- - Don't increment file count for DIRBEGIN.
- - Replace illegal characters in Win32 filename by _.
- - Add SE_CREATE_PERMANENT_NAME privilege in Win32.
- - Hash hard link filenames rather than linked list (performance).
- - Fix for security failure in chdir on Win32.
- - Add CreateDirectoryA/W win32 API entry points.
-- programs to duplicate Bacula's base64 algorithm using standard
- routines. This fixes bugs #296, and 565. Patch submitted by
- author of bug #565.
-- Fixes to reloading the Dir conf file from Eric Bollengier and Christopher
- Hull.
-- Modify LICENSE to correct some problems pointed out by Debian.
-- Apply a patch submitted by cesarb in bug #606 to implement O_NOATIME support.
- O_NOATIME is a open() flag which makes it possible to read a file without
- updating the inode atime (and also without the inode ctime update which
- happens if you try to set the atime back to its previous value). It also
- prevents a race condition when two programs are reading the same file, but
- only one does not want to change the atime. It's most useful for backup
- programs and file integrity checkers (and bacula can fit on both
- categories).
- You enable it in the Bacula FileSet Options resource by setting:
- noatime = yes
- The effect of this option is similar to the keepatime option except
- it is more efficient and avoids modifying ctime.
-- Implement a pile of new man pages contributed by Jose Tallon.
-- Modify the database format for handling Migration jobs:
- Add PriorJobId, RealEndTime to Job table
- Delete MAC table
- Remove Stripe from JobMedia record (not used, wasting space)
- Add ScratchPoolId, RecyclePoolId, Enabled to Media record
- Add Cost to Location table.
- Enabled to Media table and Location table.
-- Security: harden authentication failure in FD by single threading errors
- and forcing a 6 second wait.
-- If using GCC (actually g++) add the following compiler flags
- -fno-strict-aliasing -fno-exceptions -fno-rtti
-- Turn on new bsnprintf() code. The reason for this code is to
- eliminate the security problems associated with using the
- system libraries print routines.
-- Implement job report that indicates where Storage and Pool
- came from -- with overrides and Pool storage and NextPool,
- it is all very complicated.
-- Add more detail (Storage, Device) to list of volumes printed
- for restore.
-- Add new VOLMGMT message class. No messages are yet sent with this
- class.
-- Improved Bacula rescue procedures -- see the Disaster Recovery
- chapter of the manual
-- Add spooling/despooling info in status output of SD.
-- Add Comment field to llist of a volume.
-- Allow true/false in many but not all yes/no directives.
-- The Bacula source code is now copyrighted by the Free Software
- Foundation Europe. The Developer's Guide documents the new procedures,
- and the LICENSE file has been updated.
-- Apply Jaime Ventura's patch that implements the Messages resource
- Mail On Success directive.
-- The Client returns its Version string, which is printed in the Job
- report.
-- The Client returns whether or not VSS and Encryption are used, which
- are printed in the Job report.
-
-Additional Features Added for Win32:
-- Added DriveType directive to the Director's Include Option FileSet
- resource. Allowed values are: fixed, removable, cdrom, and remote. There
- is only an implementation for Windows because it is the only platform that
- has the concept of drives.
-
-- Adds EnhancedWild directive to the Director's Include Option FileSet
- resource. Allowed values are: yes and no.
-
- When EnhancedWild is enabled then the processing of the
- Wild, WildDir and WildFile is changed in the following ways.
-
- Patterns conform to Posix
- \ is not a special character in character classification []
- To match a - it must be the first or last character
- To match a ] it must be the first character
-
- fnmatch option FNM_FILE_NAME is specified * doesn't match a /
- so it won't match multiple directory levels in a path
-
-- Relative WildFile patterns (ones without a leading /) match
- against the filename portion. This in combination with the
- FNM_FILE_NAME fnmatch() flag makes directives such as WildFile =
- abc*.def work as expected.
-
-- Adds support for the shell's feature of brace expansion.
-
- Here is an example where braces allow 24 lines to be expressed in 5.
-
- # Exclude directories full of lots and lots of useless little files
- WildDir = "[A-Z]:/{Documents and Settings,{WINNT,Windows}/Profiles}/*/Cookies"
- WildDir = "[A-Z]:/{Documents and Settings,{WINNT,Windows}/Profiles}/*/Recent"
- WildDir = "[A-Z]:/{Documents and Settings,{WINNT,Windows}/Profiles}/*/{Local Settings,LOCALS~1}/History"
- WildDir = "[A-Z]:/{Documents and Settings,{WINNT,Windows}/Profiles}/*/{Local Settings,LOCALS~1}/Temp"
- WildDir = "[A-Z]:/{Documents and Settings,{WINNT,Windows}/Profiles}/*/{Local Settings,LOCALS~1}/Temporary Internet Files"
+The major features are:
+- First cut of bat (Bacula Administration Tool)
+- Red/Black restore in memory tree (500 times faster loading).
+- Much faster insertion of attributes (somewhere around 10 times).
+- The Regex Where code to allow easier relocation of restored files.
+- Socket level heartbeat (untested).
+- posix_fadvise() use in the FD to improve performance.
+- Simpler locking in the SD in the reservation system.
+- Much improved Volume reservation code that should eliminate most
+ conflicts experienced in multiple drive autochangers.
+- Detection of file size/date change during backup if enabled.
+- New Recycle Pool feature.
+- Efficient implementation of very large include/exclude lists.
