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. -- 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. -- 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. wx-console and gnome-console are not yet - TLS enabled. -- Any Volume in the Pool named Scratch may be reassigned to any - other Pool when a new Volume is needed. -- Seeking on disk Volumes during restore. -- 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). -- 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). - -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 = 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!!! -- TLS for wx-console is only partially implemented. TLS for - the Gnome console is not yet implemented. -- 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. -- The Python implementation has a few memory leaks not yet cleaned - up. As long as you restart Bacula once a month, this shouldn't - be an issue. -- You must either create a new catalog database or upgrade your - 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, - 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 splitted in 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 + + Bacula code: Total files = 438 Total lines = 154,329 (*.h *.c *.in) + +The major features are: +- First cut of bat (Bacula Administration Tool) +- Red/Black restore in memory tree (500 times faster loading). +- Much faster insertion of attributes (somewhere around 10 times). +- The Regex Where code to allow easier relocation of restored files. +- Socket level heartbeat (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. +- Efficient implementation of very large include/exclude lists.
