- Release Notes for Bacula 1.37.12
+ Release Notes for Bacula 1.37.18
- Bacula code: Total files = 419 Total lines = 124,877 (*.h *.c *.in)
+ Bacula code: Total files = 425 Total lines = 137,071 (*.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.
+ upgraded at the same time. Deamons are not compatible with
+ prior versions. All FDs must be upgraded.
+- There is a new database format that is not compatible
+ with previous databases.
- SQLite3 support, but it seems to run at 1/2 to 1/4 the speed of
SQLite2.
-- First cut at ANSI labels.
+- Multiple drive autochanger support.
+- Support for ANSI/IBM 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.
+ drives.
- Python Event support has been added. See below for
- configuration and details.
+ configuration and details. Unfortunately, it is not yet complete
+ and the only really useful function is defining a new
+ Volume name.
- DVD writing support, using parts, and a lot of new directives in
- the Device resource of the Storage configuration file.
+ the Device resource of the Storage configuration file thanks
+ to Nicolas Boichat.
- Seven new options keywords in a FileSet resource:
ignorecase, fstype, hfsplussupport, wilddir, wildfile, regexdir,
- and regexfile. See below for details.
+ and regexfile thanks to Pruben Guldberg). See below for details.
- Restore of all files for a Job or set of jobs even if the file
records have been removed from the catalog.
- Restore of a directory (non-recursive, i.e. only one level).
-- Support for Unicode filenames on Win32.
-- Support for TLS (ssl) between all the daemon connections.
+- Support for TLS (ssl) between all the daemon connections thanks
+ to Landon Fuller.
+- Any Volume in the Pool named Scratch may be reassigned to any
+ other Pool when a new Volume is needed.
+- You may clone a Job and thus write (almost) the same data
+ to multiple Volumes simultaneously (see below). Actually,
+ any Job may start any other Job with this mechanism, so it
+ also be used to group jobs.
+- Unicode filename support for Win32 (thanks to Thorsten Engel)
+- New manual format with an index (thanks to Karl Cunningham).
+- New Web site format (thanks to Michael Scherer).
+- Seeking on disk Volumes during restore.
New Directives:
- New Run directive in Job resource of DIR. It permits
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
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).
+ old database (the PostgreSQL upgrade scripts not yet tested).
+- You must add --with-openssl to the configure command line if
+ you want TLS communications encryption support.
Other Items:
- 2 new scripts, dvd-writepart and dvd-freespace, in the scripts directory,
- Part files support: File volumes can now be splitted in multiple
files, called "parts".
-NOTE THE FOLLOWING IS NOW OUT OF DATE!!!!
-- 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
