- Release Notes for Bacula 1.37.2
+ Release Notes for Bacula 1.37.12
- Bacula code: Total files = 398 Total lines = 117,151 (*.h *.c *.in)
+ Bacula code: Total files = 419 Total lines = 124,877 (*.h *.c *.in)
+Note! 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.
+ 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 = <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:
+- "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:
import bacula
- The script is called with one argument, typically called j. This
- argument *must* be passed unchanged to each bacula function. The
+ 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:
- bacula.get(j, "Variable-name")
+ jcr.get("Variable-name")
- where j is the argument passed to the function, and 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,
Bacula varibles can be set using Python keyword arguments:
- bacula.set(jcr=j, VolumeName="xyz")
+ jcr.set(VolumeName="xyz")
The two currently implemented writable "variables" are:
It is possible to submit a Bacula run command with the following:
- bacula.run(j, "run kernsave client=Matou storage=File")
+ 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.

- jobid = bacula.get(j, "JobId")

+ client = jcr.get("Client")

if (jobid < 5) :
- startid = bacula.run(j, "run kernsave")
+ startid = jcr.run("run kernsave")
