After many years of use or customizations Bacula (e.g.: rename or disable clients, filesets etc.) it is likely that your catalog has orphaned entries: information that remains in the database but do not have relating indexes to existing retained backups. The same thing may happen to restore jobs information that may be no longer needed if you could validate the restore contents. This behavior can leave the more complex management of Bacula and bring some impact on the catalog performance.
Fortunately there is the dbcheck application that is installed with the Bacula Director can be used to clean those entries. The main requirement for this command is only to inform the Bacula working directory, set in the bacula-dir.conf.
Usage: dbcheck [-c config ] [-B] [-C catalog name] [-d debug_level] [] []
To estimate the amount of entries that can be discarded can be used the -b option . It is likely dbcheck asks to creating new indexes to optimize its routines:
[root@localhost bacula]# sudo -u bacula dbcheck -b /opt/bacula/working/
