The DB has been upgraded from version 8 to 9 and requres +a DB upgrade. Major Changes: -- There is a new Win32 pebuilder rescue disk thanks to Scott. This - is worth the effort to checkout. -- A number of indexes have been removed from the PostgreSQL - database to improve performance during backups. You may need to - add these indexes if you do Verifies. See the scripts. -- We now have a Gentoo ebuild -- thanks Scott. -- There are a number of new ./configure options for the - bimagemgr. Please see the documentation or ./configure --help -- The RedHat autostart scripts disable using /lib/tls. If you - don't want this you will need to turn it off. -- Corrected a problem with the default SD and FD conf files that - incorrectly set Maximum Concurrent Jobs = 1. This prevented - running a job and obtaining the status at the same time. -- All daemon messages are now prefixed with a short date/time, - and queued messages (generated in the comm routines) have the - time the message was generated rather than the time the message - was sent (usually much later). -- Fixed a bug with the autochanger code not respecting the InChanger - flag. - +- The Python interface has been updated to be object oriented. +- This version has a new DIR <--> SD protocol. Both must be + upgraded at the same time. +- This version has a new database format that is not compatible + with previous databases. The upgrade scripts should work, but + they are not yet tested. +- SQLite3 support, but it seems to run at 1/2 to 1/4 the speed of + SQLite2. +- First cut at ANSI labels. +- New communications protocol between DIR and SD to reserve + drives. The DIR and SD are no longer compatible with 1.36 or + lower versions. +- Preliminary Python Event support has been added. See below for + configuration and details. +- DVD writing support, using parts, and a lot of new directives in + the Device resource of the Storage configuration file. +- Seven new options keywords in a FileSet resource: + ignorecase, fstype, hfsplussupport, wilddir, wildfile, regexdir, + and regexfile. See below for details. New Directives: -- None since 1.36.0 +- New Run directive in Job resource of DIR. It permits + cloning of jobs. To clone a copy of the current job, use + Run = "job-name level=%l since=\"%s\"" + Note, job-name is normally the same name as the job that + is running but there is no restriction on what you put. If you + want to start the job by hand and use job overrides such as + storage=xxx, realize that the job will be started with the + default storage values not the overrides. The level=%l guarantees + that the chosen level of the job is the same, and the since=... + ensures that the job uses *exactly* the same time/date for incremental + and differential jobs. The since=... is ignored when level=Full. + A cloned job will not start additional clones, so it is not possible + to recurse. +- New Options keywords in a FileSet directive: + - WildDir xxx + Will do a wild card match against directories (files will not + be matched). + - WildFile xxx + Will do a wild card match against files (directories will not + be matched). + - RegexDir xxx + Will do a regular expression match against directories (files + will not be matched). + - RegexFile xxx + Will do a regular expression match against files( directories + will not be matched). + - IgnoreCase = yes | no + Will ignore case in wild card and regular expression matches. + This is handy for Windows where filename case is not significant. + - FsType = string + where string is a filesystem type: ext2, jfs, ntfs, proc, + reiserfs, xfs, usbdevfs, sysfs, smbfs, iso9660. For ext3 + systems, use ext2. You may have multiple fstype directives + and thus permit multiple filesystem types. If the type + specified on the fstype directive does not match the + filesystem for a particular directive, that directory will + not be backed up. This directive can be used to prevent + backing up non-local filesystems. + - HFS Plus Support = yes | no + If set, Mac OS X resource forks will be saved and restored. +- Label Type = ANSI | IBM | Bacula + Implemented in Director Pool resource and in SD Device resource. + If it is specified in the SD Device resource, it will take + precedence over the value passed from the Director to the SD. + IBM is not yet implemented. +- Check Labels = yes | no + Implemented in the SD Device resource. If you intend to read + ANSI or IBM labels, this *must* be set. Even if the volume + is not ANSI labeled, you can set this to yes, and Bacula will + check the label type. +- Scripts Directory = name. Defines the directory from + which Bacula scripts will be called for events. In fact, Bacula + appends this name to the standard Python list of search directories, + so the script could also be in any of the Python system directories. +- In FileSet, you can exclude backing up of hardlinks (if you have + a lot, it can be very expensive), by using: + HardLinks = no + in the Options section. Patch supplied by David R Bosso. Thanks. +- MaximumPartSize = bytes (SD, Device resource) + Defines the maximum part size. +- Requires Mount = Yes/No (SD, Device resource) + Defines if the device require to be mounted to be read, and if it + must be written in a special way. If it set, the following directives + must be defined in the same Device resource: + + Mount Point = directory + Directory where the device must be mounted. + + Mount Command = name-string + Command that must be executed to mount the device. Before the command + is executed, %a is replaced with the Archive Device, and %m with the + Mount Point. + + Unmount Command = name-string + Command that must be executed to unmount the device. Before the + command is executed, %a is replaced with the Archive Device, and + %m with the Mount Point. + + Write Part Command = name-string + Command that must be executed to write a part to the device. Before + the command is executed, %a is replaced with the Archive Device, %m + with the Mount Point, %n with the current part number (0-based), + and %v with the current part filename. + + Free Space Command = name-string + Command that must be executed to check how much free space is left + on the device. Before the command is executed, %a is replaced with + the Archive Device, %m with the Mount Point, %n with the current part + number (0-based), and %v with the current part filename. +- Write Part After Job = Yes/No (DIR, Job Resource, and Schedule Resource) + If this directive is set to yes (default no), a new part file will be + created after the job is finished. New Commands: -- None since 1.36.0 +- "python restart" restarts the Python interpreter. Rather brutal, make + sure no Python scripts are running. This permits you to change + a Python script and get Bacula to use the new script. Items to note!!! -- The output from Job reports has been modified to include the - seconds on the start/end times, the Storage device used, and to - indent the output differently. -- If you created a PostgreSQL database under version 1.36.0, there - are two things you might want to do. 1. manually remove some - of the File table indexes to improve backup performance. See the - make_postgresql_tables script. 2. run fix_postgresql_tables (in - src/cats and updatedb) to correct a table. This is necessary only - if you are creating disk Volumes greater than 2GB. -- As of 1.35.5 you MUST do a database update. - - cd scripts-dir (or src/cats) - ./update_bacula_tables - -- All daemons should be compatible with 1.34 with the exception - of the new FileSet features such as regular expressions. -- Regular expressions are not supported in the Win32 FD. +- You must add --with-python=[DIR] to the configure command line + if you want Python support. Python 2.2 and 2.3 should be automatically + detected if in the standard place. +- With Python 2.2 version, the link of the Director gets a few linker + warnings due to the fact that Python pulls in some old non-secure + libraries. +- With Python 2.3, there are a few compiler warnings. +- You must either create a new catalog database or upgrade your + old database (upgrade scripts not yet tested). Other Items: -- It is now possible to build the Rescue CDROM using a pre-installed - static Bacula FD. -- Corrected a bug in the traceback code when Bacula was executed without - a path. Tracebacks should now work in more cases. -- Corrected a typo in the traceback script. -- Fixed the mtx autochanger script so that it correctly waits on - Linux systems (if you manually enable the code). -- Added grant all on cdimages for PostgreSQL users of bimagemgr. -- The actual Job start time is now correctly recorded in the catalog. -- You can now specify a JobId (or multiple ones separated by commas) on - the restore command line. -- A -d50 will now turn on lots of debug code if you are having - authentication errors. -- Found a workaround to a /lib/tls pthreads bug (a library seg fault). -- Added an ALERT message class for Alert messages. -- Fixed a seg fault in the restore tree routine when attempting - to select certain files in the root directory. -- Allow other jobs to request new Volumes while operator intervention - is needed -- previously all stalled. -- Enhancements to btape test (don't loop if certain tape errors occur). -- Improvements to the Win32 install. +- 2 new scripts, dvd-writepart and dvd-freespace, in the scripts directory, + which are designed to be used as parameters to Write Part Command and + Free Space Command. They need the dvd+rw-tools to be installed + (http://fy.chalmers.se/~appro/linux/DVD+RW/). +- Part files support: File volumes can now be splitted in multiple + files, called "parts". +- Python scripting support: + A Python script will be called at particular points or conditions + in Bacula called Events. The currently defined Events are called: + + StartJob, EndJob, NewVolume + + Where StartJob is called before the RunBeforeJob, EndJob is called + after RunAfterJob, and NewVolume, is called before all other + "methods" of obtaining a new Volume name, when one is needed. + + The Python script of the same name as the Event name (but with a .py) + is called from the Scripts Directory (a directive defined in the + Director resource). Note, both the Filename, and the name of + the function in the file must correspond to the Event name. + + Once the Python script gets control, it can have access to Bacula + variables by doing: + + import bacula + + The script is called with one argument, typically called jcr. This + argument *must* be used to access each bacula function. The + format of the call is slightly different for reading Bacula + variable and for writing bacula variables. See below. + + Bacula variables can be read with: + + jcr.get("Variable-name") + + where jcr is the argument passed to the function, and Variable-name + is on of the following: + + JobId, Client, Pool, Storage, Catalog, MediaType, NumVols, DirName, + Level, Type, Job, JobName, JobStatus + + Bacula varibles can be set using Python keyword arguments: + + jcr.set(VolumeName="xyz") + + The two currently implemented writable "variables" are: + + VolumeName and JobReport + + It is possible to submit a Bacula run command with the following: + + jcr.run("run kernsave client=Matou storage=File") + + this function returns the JobId of the job that was started. If + there is an error, the return value is zero. + + Example: + +== File EndJob.py === +import bacula + +def EndJob(jcr): + jobid = jcr.get("JobId") + client = jcr.get("Client") + jcr.set(JobReport="EndJob output: JobId=%d Client=%s.\n" % (jobid, client)) + if (jobid < 5) : + startid = jcr.run("run kernsave") + print "Python started jobid=", startid + + return 1 +==== + +== File NewVolume.py === +import bacula +def NewVolume(jcr): + jobid = jcr.get("JobId") + print "JobId=", jobid + client = jcr.get("Client") + print "Client=" + client + numvol = jcr.get("NumVols"); + print "NumVols=", numvol + jcr.set(JobReport="New Volume set for Job.\n") + jcr.set(VolumeName="TestA-001") + return 1 +====
