================== Warning !!!!!! ==========================
- The new pruning algorithm will not allow to prune jobs that are essential to
- restore since the last Full backup. (TODO: see for an option...)
+ The new pruning algorithm will not allow pruning of jobs that are essential to
+ restore since the last Full backup. This is, of course, correct and desirable,
+ but it is different from older Bacula versions that could inappropriately
+ prune jobs. Pruning of volumes is not affected.
+
+Building Bat:
+-------------
+To build Bat, you need Qt4 version 4.6.2. If you build with any other
+version it is likely not to work. If you do not have version 4.6.2, on
+your system, you can download the Bacula depkgs_qt version 16Dec10.
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
+14). The Bacula project rpm spec files have been modified to
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:
+source (i.e. manually):
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
Changes:
Speed and Memory Usage Enhancements:
-- Implement LZO compression algorithm
+- 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.
Security Enhancements:
- Additional security against injection of illegal characters
-- Possible fnmatch problem
+- Fix possible fnmatch problem
Features Enhancements:
- Improvements in ACL and xattr handling on additional platforms:
- 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.
+ libbacsql.so/dll needs to be changed to switch from one database backend
+ to another (e.g. MySQL to PostgreSQL).
- 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
+- The old bat version browser has been turned off since it does not
+ work correctly and the brestore panel provides the same functionality
- Improved hash table for hard links
- Additional script variable editing such as %b (JobBytes), %F (JobFiles)
and %h (Client Address)
- Many new plugin API features
- Improved memory handling for restores
- Significant stability enhancements to bat
