- Release Notes for Bacula 1.37.3
-
- Bacula code: Total files = 411 Total lines = 121,855 (*.h *.c *.in)
-
-
-Major Changes:
-- This version has a new database format that is not compatible
- with previous databases. There are NO upgrade scripts yet.
-- Due to the massive changes made during the last two weeks,
- version 1.37.3 should be considered unstable. It does, however,
- pass the regression tests.
-- SQLite3 support.
-- First cut at ANSI labels.
-- New communications protocol between DIR and SD to reserve
- drives.
-
-
-- Preliminary Python Event support has been added. See below for
- configuration.
- 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 j. This
- argument *must* be passed unchanged to 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")
-
- where j 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:
-
- bacula.set(jcr=j, VolumeName="xyz")
-
- The two currently implemented writable "variables" are:
-
- VolumeName and JobReport
-
- It is possible to submit a Bacula run command with the following:
-
- bacula.run(j, "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(j):
- jobid = bacula.get(j, "JobId")
- client = bacula.get(j, "Client")
- bacula.set(jcr=j, JobReport="EndJob output: JobId=%d Client=%s.\n" % (jobid, client))
- if (jobid < 5) :
- startid = bacula.run(j, "run kernsave")
- print "Python started jobid=", startid
-
- return 1
-====
-
-== File NewVolume.py ===
-import bacula
-
-def NewVolume(j):
- jobid = bacula.get(j, "JobId")
- print "JobId=", jobid
- client = bacula.get(j, "Client")
- print "Client=" + client
- numvol = bacula.get(j, "NumVols");
- print "NumVols=", numvol
- bacula.set(jcr=j, JobReport="New Volume set for Job.\n")
- bacula.set(jcr=j, VolumeName="TestA-001")
- return 1
-====
-- Part files support: File volumes can now be splitted in multiple
- files, called "parts".
-- DVD writing support, using parts, and a lot of new directives in
- the Device resource of the Storage configuration file.
-
-New Directives:
-- 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.
-
-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/).
+ Release Notes for Bacula 2.1.10
+
+ Bacula code: Total files = 458 Total lines = 170,197 (*.h *.c *.in)
+
+This Director and Storage daemon must be upgraded at the same time,
+but they should be compatible with all 2.0.x File daemons, unless you
+use some of the new features that affect the FD. In other words, you should
+not have to upgrade all your File daemons. However, bat works only with
+a 2.1.8 Director.
+
+Areas requiring caution or testing:
+- You must have Qt4 Version 4.2 or greater loaded to build bat
+- You must have the thread safe version of MySQL client libraries loaded
+ to build with MySQL enabled.
+- The Volume management in the Storage daemon is extensively rewritten.
+ It appears to function much better, but is largely untested under
+ severe stress conditions (multiple drive autochangers, ...).
+- Volumes are pruned only when absolutely necessary -- this may cause
+ your database to grow.
+- Socket level heartbeat is untested.
+- Solaris door and even port files are no longer restored (equivalent
+ to what we do with sockets).
+- Solaris is untested
+- Win32 servers are untested, and very likely not to work.
+
+The major new features are:
+- Much faster insertion of attributes (somewhere around 10 times),
+ many thanks to Eric Bollengier and Marc Cousin.
+- First cut of bat (Bacula Administration Tool). Note to build
+ bat you must explicitly enable it on the ./configure line, you
+ must have the Qt4 version 4.2 or later libraries loaded, and
+ qmake and the other Qt4 tools must be available. bat is ALPHA
+ software. A large part of the work was done by Dirk Bartley.
+- Red/Black restore in memory tree (500 times faster loading).
+- The Regex Where code to allow easier relocation of restored files
+ thanks to Eric.
+- Socket level heartbeat for all connections (untested).
+- posix_fadvise() use in the FD to improve performance.
+- Simpler locking in the SD in the reservation system.
+- Much improved Volume reservation code that should eliminate most
+ conflicts experienced in multiple drive autochangers.
+- Detection of file size/date change during backup if enabled.
+- New Recycle Pool feature -- thanks to Eric.
+- Efficient implementation of very large include/exclude lists.
+- Volumes are no longer pruned during 'status dir'
+- Pruning is now more efficient, and if a Volume is purged,
+ during pruning, it is immediately discovered.
+
+Other features or bug fixes:
+- Fixed bugs: 856, 854, 845, 847, 846, 809, 772,
+ 822, 825, 824, 808, 802, 797, 798, 795, 789, 791,
+ 788, 780, 763, 782, 612, 767, 775, 621, 772, 764,
+ 766, 621, 761, 755, 750, 741, 747, 742, 744, and 743.
+- Only the minumum number of volumes are pruned rather than
+ all volumes in the pool.
+- wx-console renamed to bwx-console
+- gnome-console renamed to bgnome-console
+- Migration preserves original job's FileSetId
+- Spooling implemented for migration jobs.
+- Config files can be read through a pipe, by specifying a leading |
+ in front of the configuration path/filename.
+- New memory command (bconsole) that will print the current Director's
+ memory usage, and a in use buffer dump.
+- Solaris door and event port files are no longer restored.
+- Console name changed from *Console* to -Console- to accomodate Win32
+ filename restrictions.
+- Corrected Win32 ftruncate bug.
+- Additional version information added to Job reports.
+- New -8 option for bsmtp to specify UTF-8 encoding type.
+- bsmtp will no longer add < > to target (from, to, cc) if there
+ is already a < in the target.
+- Perfer Mounted Volumes extended to mean a volume that is being
+ mounted by another job.
+- Runscript timing set to same as version 1.38.11
+- New TLS Allowed CN directive(s) permitted.
+- New bconsole 'exec' command to run external script/command.
+- Turn on FreeBSD/OpenBSD code to set EOT model on tape.
+- Drop from root done before database is opened.
+- database user and name can be configured with:
+ --with-db-name=name --with-db-user=user
+- turn on wait_for_drive in mtx-changer script.
+- rework how bar codes are handled in mtx-changer script.
+ This appears to have been an unreported bug.
+- Updated nagios plugin supplied by Christian Masopust
+- Better restricted console ACL checking.
+- New Client Connect Wait directive in Storage daemon so that
+ users can configure how long SD waits for FD connection.
+- Bacula will no longer permit pruning of the currently running
+ job (note, if other jobs are running, they may be pruned).
+- Sockets are no longer restored.
+- dbcheck works in 300K chunks so will typically run faster.
+- Include/Exclude lists can now be efficiently handled for quite
+ large sizes -- tens of thousands of entries.
+- Several memory leaks in migration and database usage were fixed.
+- New console keyword restoreclient, which specifies the client to
+ which the restore will be sent. The client keyword specifies
+ the backup client. The restoreclient keyword is optional if it is
+ not specified, the backup client will also be the restore client.
+- The disk file size is now checked to ensure that it agrees with the
+ catalog value before Bacula will append to the disk (same as tape
+ and DVD).
