Fixes bug #457. +- Remove @STATIC_CONS@ from tray-monitor Makefile as suggested + by user. Fixes bug #456. +- AMD64 users see compiler bug warning below!!!!!!!!! -Major Changes: -- Tray monitor program (really cool) -- Bacula Rescue CDROM (easy to make and essential for emergencies) -- Bacula CD Image Manager -- General bug fixes/stabilization -- French translation of manual by Ludovic Strappazon well - underway. -- UTF-8 is supported in conio. -- Improved conf scanning code allowing FileSet components to - be put on a single line (previously everything had to be on - a different line). -- Win32 files restored to an alternate directory will have the - colon following the drive letter turned into a / e.g. c: - becomes c/. Previously the c: was stripped. This applies only - to files written to an alternate directory (i.e. using a where=). -- Certain open files (Word for example) can now be saved on - Win32 systems. -- Default for Wild-cards on Win32 systems is to fold case this - should correct most of the problems users are having with - exclusion on Win32. -- Lots of improvements in the Rescue scripts -- better - network detection, better mounting code, ... -- The attributes spool file can now exceed 2GB. -- Significant speed improvements when running PostgreSQL. -- Significantly faster restore command with very large - FileSets while building the in memory directory tree. -- Patches directory in the source will have all patches - that have not been applied and released (new releases are - only generated when really critical bugs are found). -- Bacula forces the tape drive into variable block mode - on most systems (providing Bacula is running in variable - block mode). -- dbcheck updated to remove many more orphaned records. -- Support for IPv6 (untested). -- Modifications to the license to termination clause for - more protection from SCO type predators. No change for - normal users. -- SIGHUP to Director causes it to reload conf file. - -- Many improvements in the documentation. +Major Changes in 1.38: +- Fixed out of order Volumes in restore. +- Improved algorithm for reserving drives in multiple drive + autochangers. Autochange users MUST use the new Autochanger + resource in the Storage daemon. +- There is a new database format that is not compatible + with previous databases. You must upgrade if converting + from 1.36.x. No changes from version 1.37.30. +- The Director, Storage daemon, and File daemons are + Deamons are not compatible with prior versions. + All FDs must be upgraded at the same time. +- Support for ANSI/IBM labels. +- 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. The implementation is somewhat minimal, + so the functionality is not complete. The Python interface + has not been extensively tested, so please consider it BETA. +- DVD writing support, using parts, and some new directives in + the Device resource of the Storage configuration file thanks + to Nicolas Boichat. Please note that this code is still + BETA 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. +- 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. +- Web-bacula, previously a separate project by Juan Luis Frances, + is now included in the Bacula GUI release. This is a management + level tool for reporting the state of Bacula jobs. +- The code is now Internationalized so that it can be localized + in native languages. Thanks to Nicolas Boichat. New Directives: -- Added "Rerun Failed levels = yes/no" in the Job resource - of the Director. It will upgrade the current job to a - higher level (Full or Differential) if a previous job - of that level failed. -- Added "Ignore FileSet Changes = yes/no" in the FileSet - directive of the Director. It prevents the Director from - immediately upgrading the job to a Full save if you modify - the contents of the FileSet. Not recommended. -- Added "Block positioning = yes/no" in Device resource in SD. - If set to no, Bacula should (as yet untested) be able to - recover data from tapes where the drive was set to fixed - blocksize but Bacula is in variable block size. -- Added "Multiple connections = yes/no" in Catalog record for - allowing multiple simultaneous connections to the database. - This is a major performance improvement for PostgreSQL and - SQLite, but it is untested, so please test before putting - it into production. -- Alert Command in SD permits checking for tape drive - alerts at the end of every job (or doing anything you want). - An example of the command is in the default bacula-sd.conf - file as well as in the Storage Configuration chapter of - the manual. +- 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 (backported to 1.36.3): + - 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: -- umount -- same as unmount. -- delete job now permits multiple jobids and ranges, e.g.: - delete job jobid=1,3,5,11-16 -- reload -- reloads bacula-dir.conf in Director. +- "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. + +New configure options: +- --with-libintl-prefix for defining alternate locations for + the NLS internationalization libraries. Not normally required. +- --datadir for defining where the language files will be installed + required only if you do not want the default /usr/share. Items to note!!! -- As of 1.35.5 you MUST do a database update. - - cd scripts-dir (or src/cats) - ./update_bacula_tables - -- All daemons should be compatible with 1.34 with the exception - of the new FileSet features such as regular expressions. -- Regular expressions are not supported in the Win32 FD. +- 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. +- 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. After installation, run from your scripts + directory: -Other Items: -- Much better error messages from system errors particularly - on Win32 and in running scripts. -- Many improvements in the SD. -- Full support for 64 bit machines. -- btape improved test and fill commands. -- See the ChangeLog for additional details. + ./upgrade_bacula_tables + You can also find this script in the /src/cats + directory. +- The Director, Storage daemon, and File daemons are + Deamons are not compatible with prior versions. + All FDs must be upgraded at the same time. +- You must add --with-openssl to the configure command line if + you want TLS communications encryption support. +- Disk seeking during restores does not yet work correctly in + all cases, so it is turned off. +- Note, with gcc (GCC) 4.0.1 20050727 (Red Hat 4.0.1-5) on an + AMD64 CPU running 64 bit CentOS4, there is a compiler bug that + generates bad code that causes Bacula to segment fault. + Typically you will see this in the Storage daemon first. The + solution is to compile Bacula ensuring that no optimization is + turned on (normally it is -O2). + This same compiler bug has been reported and confirmed with + gcc (GCC) 4.0.2 20050901 (prerelease) (SUSE Linux) running on + an AMD64 CPU. This for the moment, I would recommend that all + users of GCC 4.0.1 or greater turn off all optimization when + compiling. + + +Other Items: +- Security fixes for temp files created in mtx-changer, during + ./configure, and during making of Rescue disk. +- A new script, dvd-handler, in the scripts directory, + which is 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/) AND, the growisofs + program must be patched using the + /patches/dvd+rw-tools-5.21.4.10.8.bacula.patch + You must have Python installed to run the scripts. +- 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.
