The -days option removes media management sessions, restore sessions, and
obsolete backup sessions (backup sessions without backed up data) older than
NumberOfDays.
The -messages option removes session messages for all sessions older than
NumberOfDays.
The -dcbf option removes DCBF for all media with expired catalog protection.
The -mpos option removes all the object versions and media position records
for the overwritten tapes. If the QuickMediaFormat option is set to 1 in the
global options file, Data Protector will not purge any records during a backup
or when a media is formatted. Those obsolete records will be explicitly removed
when a purge mpos command is run. If QuickMediaFormat is not set, the
records will be purged from the database during the course of the backup.
The -daily option starts the same purge session as started every day at 12:00
(depending on the Data Protector global options file setting) and is a part of
Data Protector daily maintenance tasks. This purge session deletes DCBF based
on the catalog protection and removes obsolete sessions and their messages, by
running the omnidbutil -purge -sessions KeepObsoleteSessions
-messages KeepMessages -dcbf command, where
KeepObsoleteSessions and KeepMessages are specified in the Data
Protector global options file. Default values for these two parameters are 30 and
0, respectively. The Data Protector global options file resides on the Cell Manager
in the directory
Data_Protector_program_data\Config\Server\options (Windows
Server 2008), Data_Protector_home\Config\Server\options (other
Windows systems) or/etc/opt/omni/server/options (UNIX systems). The
scheduled time for the -daily option to start every day is defined by the
DailyMaintenanceTime option in the Data Protector global options file.
At least one of these options must be specified. You can change or disable the
global option DailyMaintenanceTime for the -daily option.
-purge_failed_copies
In certain circumstances the Data Protector IDB may hold multiple copies of objects
made during a backup. Use this option to remove all unrequired copies that may
overload an IDB. This option requires exclusive access to the database.
-purge_stop
Use this option to stop a running file name purge session. This command only
sends a stop request to the Purge Session Manager. The response may not be
immediate.
