======== PostgreSQL, MySQL and SQLite databases

Bacula director supports different databases backends, if you want to switch
away from the default PostgreSQL one you need to change the "libbaccats" (the
catalogue library) symlink to the real library.

To change to a different backend, issue the following command:

# alternatives --config libbaccats.so

There are 3 programs which provide 'libbaccats.so'.

  Selection    Command
-----------------------------------------------
   1           /usr/lib64/libbaccats-mysql.so
   2           /usr/lib64/libbaccats-sqlite3.so
*+ 3           /usr/lib64/libbaccats-postgresql.so

Enter to keep the current selection[+], or type selection number: 1

There is NO need to edit any part in the Bacula Director configuration; for the
purposes of the database creation steps, the bacula-dir.conf configuration file
can be left at their default values.

======== Switiching between PostgreSQL, MySQL and SQLite backends

To switch the configured backend to another one, follow the above procedure.
Again, there's no need to edit the Bacula Director configuration file; the
catalog resource can be left as is.

Importing and exporting data between the various database formats is up to the
user. If the database will be re-initialized from scratch, follow the quick
start guides mentioned above.
