Fixes bug #457. +- Remove @STATIC_CONS@ from tray-monitor Makefile as suggested + by user. Fixes bug #456. +- AMD64 users see compiler bug warning below!!!!!!!!! -New Commands: -- "SetIP" -- Added "pool=xxx" to restore command line. -- Added "fileset=xxx" to restore command line. -- Fixed "storage=xxx" on restore command line. -- "markdir" command in restore tree. -- "unmarkdir" command in restore tree. -- "quit" command in restore tree. +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: +- 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. -Most Significant Changes since 1.32d -- The ability to ask the Storage daemon on a device by device basis - to "poll" the tape drive at a given interval (minimum 1 minute). If - a tape is found, its label is read and if appropriate it is used. - This eliminates the need to do "mount" commands. -- The ability to close and re-open the device when a poll occurs. - This permits dealing with certain recalcitrant autochangers that - invalidate devices (typically on FreeBSD). -- Dan Langille has written a PostgreSQL driver for Bacula. -- Implement "update slots scan" that reads the volume label(s). -- The full form of the scan is "scan=1,2,4-5,7". With no specification, - all occupied slots are scanned. -- Turn off changer Volumes that are not current in the changer when - an "update slots" is done, or if any tape operation discovers that - the right volume is not in the slot. -- The console program will run all commands it finds in ~/.bconsolerc - at startup. -- Add Dan Langille's changes to the bacula start/stop script that - permit dropping root permissions just after startup. -- New version 1.5.5-1 Cygwin. -- Modify SD to update the catalog database when it is shutdown, - even if the job is canceled. -- Fixed seg fault in restore of multiple simultaneous jobs to - a single Volume. -- Fixed thread race problem in multiple simultaneous jobs to - a single Volume where the volume lable is not in the first - tape block, so the tape is not recognized. +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. -Other Changes since 1.32d -- Restore directory tree automatically selects all higher level - directories to be restored. -- Implement conio.c to use in console program -- mini-readline. -- Enhance "fill" command of btape -- simpler output. Use -v to - cause last block to be dumped after write and after re-read. -- Added an autochanger test to the btape "test" command. It is - automatically invoked if the autochanger is properly configured. It - is still a bit primitive but covers the essential of testing - the mtx-changer script with your autochanger. -- Select the oldest LastWritten volume during recycling. -- Added forward space file test to btape "test" command. -- All 1.32d patches applied. -- Fixed seg fault in restore of multiple simultaneous jobs to - a single Volume. -- Fixed thread race problem in multiple simultaneous jobs to - a single Volume where the volume lable is not in the first - tape block, so the tape is not recognized. +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: !!!!! -- FreeBSD users NOTE!!!!! - You MUST add the following two records to your SD Device resource for - tape drives. +Items to note!!! +- 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: - TWOEOF = yes - Fast Forward Space File = no + ./upgrade_bacula_tables -- The daemon protocol has changed, you must update everything at once. -- The database level has been updated. You must either re-initialize - your databases with: - - ./drop_bacula_tables - ./make_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. - which will delete ALL prior catalog information, or you can - update your database with: - ./update_bacula_tables -- smtp has now become bsmtp -- console has now become bconsole. -- console.conf is now bconsole.conf -- Please don't underestimate the repercussions of the bsmtp and bconsole - name changes! +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.
