Release Notes for Bacula 1.37.24 Bacula code: Total files = 433 Total lines = 140,329 (*.h *.c *.in) Major Changes: - This version has a new DIR <--> SD protocol. Both must be 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. - 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. - 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). - 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 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. - The new DVD code is currently non-functional. 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". - For the details of the Python scripting support, please see the new Python Scripting chapter in the manual.
