Hello,
This is to let you know that the source tar files and the Win32 binaries
for Bacula BETA version 5.2.0rc1 have been released to the Bacula Source
Forge download area.
We would appreciate that packagers take some time to update their
procedure during the RC phase to have ready-to-use 5.2.0 version. It is
very likely that we will cut a RC2 release in a couple weeks.
=====
Release Notes for Bacula 5.2.0 RC 1
Bacula code: Total files = 1,110 Total lines = 231,439 (Using SLOCCount)
General:
--------
This 5.2.0 version is a major release since the last version 5.0.3.
It includes well over 50,000 lines of changes made by 19 contributors
and a number of important new features:
Compatibility:
--------------
As always, both the Director and Storage daemon must be upgraded at
the same time.
Older 5.0.x and 3.0.x File Daemons are compatible with the 5.2.0
Director and Storage daemons. 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 <your-scripts-installation-directory>
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
<bacula>/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 (To enable it, you need to have
the lzo headers installed on your system. liblzo2-dev on debian for
example).
- 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 thelibbacsql.so/dll needs to be changed.

- Disable batch insert config item
- Director selection option in bconsole
