Release Notes for Bacula 1.39.32 Bacula code: Total files = 438 Total lines = 153,698 (*.h *.c *.in) Version 1.39.32 contains mainly bug fixes to 1.39.30 Please see the ChangeLog for more details. ==== IMPORTANT Encrypted Volume data may be unreadable ==== - 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. ==== IMPORTANT a stock SuSE 10.1 kernel may crash ===== - 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. ==== 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. 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 /src/cats. It is called: ./update_bacula_tables It is necessary to run it only once the first time you move to a 1.39.x beta or to 1.40.0. 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 DVD Volume format changed ==== - 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. ==== IMPORTANT miscellaneous ==== - The Gnome console program (gconsole) no longer functions as it should. If you have multiple catalogs, you will need to select the catalog (this I will fix). 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 --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. - The "Accept Any Volume" directive has been removed. It was never implemented. Bacula will always accept any valid tape that is in the drive for appending. - You *should* be able to use 1.38.x FDs with version 1.39.18 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. ==== 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, we can change that prior to release if everyone is comfortable with it). Prior to using the current installer, if you used a version of the beta prior to 1.39.26, you must do one of the following three things: 1) Uninstall prior beta version and select the option to delete the configuration and state files. This will get rid of the bogus configuration files. Reinstall the new 1.39.26 version. 2) Manually copy the *.conf files from C:\Bacula\bin to C:\Documents and Settings\All Users\Application Data\Bacula. 3) Manually edit the *.conf files in C:\Documents and Settings\All Users\Application Data\Bacula. The links in the Bacula menu can be used to avoid having to enter that ugly path. After one of these has been done the upgrade should work fine. ====== New Features in 1.39.30: - 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. - Turn on disk seek code for restores. - 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. Major new Features in 1.40.0: - The basic features of Migration are now complete, and are documented in a new Migration chapter in the manual http://www.bacula.org/dev-manual/Migration.html - There is an Encryption chapter in the doc. 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 considered beta (i.e. test carefully before putting into production). - Data encryption done in the Client is now supported due to code submitted by Landon Fuller. - 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. - 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. - Apply patch for enhancing wait from Eric Bollengier. One can now: 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. New Features in 1.40.0: - Add enable/disable job=. 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, but this has never been tested. - 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. - 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. - 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. - 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. - 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). This is not well tested. - Integrate addition of line count limitation to bsmtp -l from Sebastian Stark - 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. - Implement a number of user supplied patches for DVD writing. - 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. - Spend a lot of time integrating mkcdrec with the rescue disk. - Add spooling/despooling info in status output of SD. - Add Comment field to llist of a volume. - Allow true/false in some yes/no questions. 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"
