The DB has been upgraded from version 8 to 9 and requres +a DB upgrade. + +Major Changes: +- 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: +- 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: -- "SetIP" -- Added "pool=xxx" to restore command line. -- Added "fileset=xxx" to restore command line. -- Fixed "storage=xxx" on restore command line. -- "markdir" command in restore tree. -- "unmarkdir" command in restore tree. -- "quit" command in restore tree. - -Most Significant Changes since 1.32d -- The ability to ask the Storage daemon on a device by device basis - to "poll" the tape drive at a given interval (minimum 1 minute). If - a tape is found, its label is read and if appropriate it is used. - This eliminates the need to do "mount" commands. -- The ability to close and re-open the device when a poll occurs. - This permits dealing with certain recalcitrant autochangers that - invalidate devices (typically on FreeBSD). -- Dan Langille has written a PostgreSQL driver for Bacula. -- Implement "update slots scan" that reads the volume label(s). -- The full form of the scan is "scan=1,2,4-5,7". With no specification, - all occupied slots are scanned. -- Turn off changer Volumes that are not current in the changer when - an "update slots" is done, or if any tape operation discovers that - the right volume is not in the slot. -- The console program will run all commands it finds in ~/.bconsolerc - at startup. -- Add Dan Langille's changes to the bacula start/stop script that - permit dropping root permissions just after startup. -- New version 1.5.5-1 Cygwin. -- Modify SD to update the catalog database when it is shutdown, - even if the job is canceled. -- Fixed seg fault in restore of multiple simultaneous jobs to - a single Volume. -- Fixed thread race problem in multiple simultaneous jobs to - a single Volume where the volume lable is not in the first - tape block, so the tape is not recognized. - -Other Changes since 1.32d -- Restore directory tree automatically selects all higher level - directories to be restored. -- Implement conio.c to use in console program -- mini-readline. -- Enhance "fill" command of btape -- simpler output. Use -v to - cause last block to be dumped after write and after re-read. -- Added an autochanger test to the btape "test" command. It is - automatically invoked if the autochanger is properly configured. It - is still a bit primitive but covers the essential of testing - the mtx-changer script with your autochanger. -- Select the oldest LastWritten volume during recycling. -- Added forward space file test to btape "test" command. -- All 1.32d patches applied. -- Fixed seg fault in restore of multiple simultaneous jobs to - a single Volume. -- Fixed thread race problem in multiple simultaneous jobs to - a single Volume where the volume lable is not in the first - tape block, so the tape is not recognized. - -Items to note: !!!!! -- FreeBSD users NOTE!!!!! - You MUST add the following two records to your SD Device resource for - tape drives. - - TWOEOF = yes - Fast Forward Space File = no - -- The daemon protocol has changed, you must update everything at once. -- The database level has been updated. You must either re-initialize - your databases with: - - ./drop_bacula_tables - ./make_bacula_tables - - which will delete ALL prior catalog information, or you can - update your database with: - - ./update_bacula_tables -- smtp has now become bsmtp -- console has now become bconsole. -- console.conf is now bconsole.conf -- Please don't underestimate the repercussions of the bsmtp and bconsole - name changes! +- "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!!! +- 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: +- 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 +====
