- Release Notes for Bacula 1.37.36
-
- Bacula code: Total files = 420 Total lines = 137,650 (*.h *.c *.in)
-
-Major Changes:
-- There is a new database format that is not compatible
- with previous databases. You must upgrade if converting
- from 1.36.x.
-- The Director, Storage daemon, and File daemons are
- Deamons are not compatible with prior versions.
- All FDs must be upgraded at the same time.
-- Multiple drive autochanger support. You *must* update
- your SD conf file.
-- Support for ANSI/IBM labels.
-- New communications protocol between DIR and SD to reserve
- drives.
-- Faster database inserts due to combining the MD5/SHA1 into
- the attributes record, eliminating one INSERT/file backed up.
-- Python Event support has been added. See below for
- 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 thanks
- to Nicolas Boichat. Please note that this code is still
- experimental and should be carefully tested before using in
- production.
-- Seven new options keywords in a FileSet resource:
- ignorecase, fstype, hfsplussupport, wilddir, wildfile, regexdir,
- 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 TLS (ssl) between all the daemon connections thanks
- to Landon Fuller. This is mostly untested.
-- 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)
-- Volume Shadow Copy support for Win32 thus the capability to
- backup exclusively opened files (thanks to Thorsten Engel).
- A VSS enabled Win32 FD is available. You must explicitly
- turn on VSS with "Enable VSS = yes" in your FileSet resource.
-- New manual format with an index (thanks to Karl Cunningham).
-- New Web site format (thanks to Michael Scherer).
-- SQLite3 support, but it seems to run at 1/2 to 1/4 the speed of
- SQLite2.
-- Web-bacula, previously a separate project by Juan Luis Frances,
- is now included in the Bacula GUI release (yet to be fully
- created).
-- The code is now Internationalized so that it can be localized
- in native languages. Thanks to Nicolas Boichat.
-
-New Directives:
-- New Job directive "Prefer Mounted Volumes = yes|no" causes the
- SD to select either an Autochanger or a drive with a valid
- Volume already mounted in preference. If none is available,
- it will select the first available drive.
-- 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.
-- 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.
-- A pile of new Directives to support TLS. Please see the TLS chapter
- of the manual.
-
-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, 2.3 and 2.4 should be
- automatically detected if in the standard place.
-- When linking with --with-python, there are a few warnings that
- can be ignored.
-- You must either create a new catalog database or upgrade your
- old database.
-- The TLS code is for the most part untested.
-- You must add --with-openssl to the configure command line if
- you want TLS communications encryption support.
-- If you use an Autochanger, you *must* update your SD conf file
- to use the new Autochanger resource. Otherwise, certain commands
- such as "update slots" may not work.
-- Disk seeking during restores does not yet work correctly in
- all cases, so it is turned off.
-
-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/).
- You must have Python installed to run the dvd-freespace script.
-- Part files support: File volumes can now be split into multiple
- files, called "parts".
-
-- For the details of the Python scripting support, please see the new
- Python Scripting chapter in the manual.
+ Release Notes for Bacula 2.2.0
