There should be no need to upgrade older File + Daemons. + +================== Warning !!!!!! ========================== + + The new pruning algorithm will not allow to prune jobs that are essential to + restore since the last Full backup. Pruning of volumes are not affected. + +New Catalog format in version 5.2.0 +----------------------------------- +This release of Bacula uses a new catalog format. We provide a set of +scripts that permit to convert a 5.0.x (version 12) catalog to 5.2.0 (version +14). 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 5.2.0 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. + +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 5.0.0 +(e.g. 3.0.3) 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. + +================================================================ + +Changes: + +Speed and Memory Usage Enhancements: +- Implement LZO compression algorithm (need lzo2 headers to activate this option) +- New Pruning algoritm -- safer and faster +- Use of PostgreSQL cursor when doing large queries, should reduce the + memory usage during restore and accurate backups. +- limit command in some list commands +- Bacula Virtual File System for fast catalog access +- Faster crc32 algorithm + +Security Enhancements: +- Additional security against injection of illegal characters +- Fix possible fnmatch problem + +Features Enhancements: +- Improvements in ACL and xattr handling on additional platforms: + AIX, Darwind, FreeBSD, HPUX, IRIX, Solaris, Tru64 +- Tray monitor for Windows +- New SQL backend and ./configure that permits building multiple catalog + backends in one build, and has the main Bacula core code totally independent + of the SQL backend, which should simplify packaging (only the + libbacsql.so/dll needs to be changed. +- Indent lsmark during restore +- Disable batch insert config item +- Director selection option in bconsole +- restorejob command in bconsole +- Many additional features for bat such as "brestore" panel +- Improved hash table for hard links +- Additional script variable editing such as %b (JobBytes), %F (JobFiles) + and %h (Client Address) + +Other Enhancements: +- Includes better handling for Windows repares points, mount points, and + junction points. +- New database format +- Many new plugin API features +- Improved memory handling for restores +- Significant stability enhancements to bat +- A few path name length limits in Windows have been removed. + + +=========================================================================== + +The 5.0.3 version is significant bug fix update to version 5.0.2.
