This fixes the bug reported by Alexander Mueller. -- Apply Jess Guardiani's second fix to list autochanger volumes without - opening the drive (necessary on FreeBSD if no tape is in the drive). -- Reworked the command line handler in restore to walk through the - arguments one at a time. This makes the file= entries work correctly. - Also reworked the code that takes the MediaType and finds a - storage device. -- Add quit command to restore tree handler. -- Make restore tree handler remember if a hard link is present, and - in doing a mark, only get database entry if there is a hard link. - mark commands thus run at least 2 orders of magnitude faster. -- Add files=xxx field to run command submitted for restore. -- Add yes to restore run command if either yes or run is command line - argument. -- Make "yes" on command line argument skip prompt for modification of - run job. -- Add markdir and unmarkdir -- both affect only the directory in - question and do not do a recursive descent. -- Make tree command automatically mark all higher level directories to - be restored when a directory or a file is selected. Such directories - are indicated by preceding the name with a + to indicate that only - the directory entry is selected and not the whole directory tree. -- Modify a few tree commands to walk through all arguments rather than - just taking the first one. -- Improved btape "test" and "fill" commands. -- 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 label is not in the first - tape block, so the tape is not recognized. -- 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. - -Items to note: !!!!! -- FreeBSD users NOTE!!!!! - You MUST add the following two records to your SD Device resource for - tape drives. - - TWOEOF = yes - Fast Forward Space File = no - -- The daemon protocol has changed, you must update everything at once. -- The database level has been updated.

It should be no need to upgrade older File +Daemon. + +============ Documentation improvements needed ================== + +Note!!!!! The 3.0.0+ documentation needs rather extensive modifications in the +following areas: + +1. Missing documentation. +2. Correction of links within various manuals -- most fail. +3. Integration of the new features into the main documents. +4. Much more. + +The documentation will not be completed in the near future due to lack +manpower. If you are unhappy with this situation as we are, we suggest +you help by submitting patches to the documentation. Thanks. +===== + +================== 3.0.1 Release Notes ======================== + +Version 3.0.1 is primarily a minor bug fix update to version 3.0.0 with +one enhancement. + +================== 3.0.0 Release Notes ======================== + +The diff between 2.4.4 and 2.5.x is 208,340 lines, so this release +represents an enormous effort. + +This Director and Storage daemon must be upgraded at the same time, +but they should be compatible with all 2.4.x File daemons, unless you +use some of the new features that affect the FD. In other words, you should +not have to upgrade all your File daemons when you upgrade. However, any +release of version 2.5.40 or greater requires a database upgrade. + +================== Warning !!!!!! ========================== + +New Catalog format in version 3.0.0 (2.5.40 or later) +----------------------------------------------------- + +This release of Bacula uses a new catalog format. We provide a set of +scripts that permit to convert a 2.4.x (version 10) catalog to 3.0.0 (version +11). The Bacula project rpms distributed on Source Forge will automatically +detect the database change and do the upgrade for you. We strongly +recommend that you save a copy of your existing database before upgrading +using rpms. + +The simplest way to upgrade the database assuming you are building from +source: +1. Stop any current version of Bacula from running. +2. Save a copy of your existing database. +3. Configure, build, and install the 3.0.0 version of Bacula + Note the new ./configure options in the manuals see the link + at the bottom of this file. +4. cd +5. ./update_bacula_tables +6. If you have multiple catalogs, edit the update_bacula_tables + script and put the name of another database, and then + execute the script again. Repeat this until all Bacula + catalogs have been updated. +7. Start the new Bacula. If everything worked, it should + not print any error messages. + +The upgrade operation will convert the FileId index field of the File table +from 32 bits to 64 bits. This operation will take TIME and will *temporarily* +DOUBLE THE SIZE of your catalog. Bacula must be shutdown during this update, +so, won't be able to run jobs during this period. For example, a 3 million files +catalog will take 2 mins to upgrade on a normal machine. Don't forget to +backup it before executing the script. + +If you start from scratch, you don't need to run the update_bacula_tables +script because the create_bacula_tables script automatically creates the new +table format. However, if you are using a version of Bacula older than 2.5.40 +(e.g. 2.4.4) then you need to run the update_bacula_tables script that will +be found in the /src/cats directory after you run the ./configure +command. As mentioned above, before running this script, please backup your +catalog database, and when you do running it, be sure shutdown Bacula and be +aware that running the script can take some time depending on your database +size. + + +Important New configure options : +---------------------- + +This release of Bacula 3.0.0 uses libtool by default +to generate the Bacula libraries as shared objects rather than +being directly linked in as in prior versions. This means that +the Bacula shared objects, must either be in a shared object +directory known to the loader or they must be in the directory +where the Bacula binaries are installed. It is also possible +to explicitly specify the libraries directory on the ./configure +line (--libdir=/full-path/dir), but this should not be necessary. + + ./configure --libdir= + +If you have problems with libtool or you wish to use the old +way of building libraries and linking them into Bacula, you +can do so by disabling libtool on the configure command line with: + + ./configure --disable-libtool + +During the installation of Bacula 3.0.0, it will now install +bat help files (if you have configured bat). These files +are placed in /usr/share/doc/bacula/html by default. If you +want to put them elsewhere use: + + ./configure --htmldir= + +During the installation of Bacula, it will now install the +ReleaseNotes, License, technotes, ChangeLog, and similar +files in /usr/share/doc/bacula by default. If you +want to put them elsewhere use: + + ./configure --docdir= + +During the installation of Bacula, any plugins will be +installed in the plugindir, which is by default the +same as libdir (/usr/lib). You can specify an alternate +location with: + + ./configure --with-plugindir= + +============================================================== + +This release includes large number of new features and changes. +It should be more or less compatible with previous xx.conf files +and File daemons providing that you are not using any of the new +features. + +Please see the New Features chapter of the new manual, which documents +some but not all the new features (we are still working on it): + +http://www.bacula.org/manuals/en/concepts/concepts/New_Features.html + + + + +The ChangeLog has more details.
