Data Protector runs daily maintenance to purge Expired Media from the Data Protector Internal Database and the Catalyst store. By default the time this maintenance runs is 12:00 NOON. The schedule for this can be changed
by editing the GLOBAL file and modifying # DailyMaintenanceTime=HH:MM
# default: 12:00 (HH:MM)
# This option is used for starting daily maintenance tasks at
# first omnitrig run after the specified time each day. Valid
# values are hour:minute, using the twenty-four hour clock
# notation.
Additionally the frequency of the purge can be adjusted as well by editing the GLOBAL file and modifying
DeleteUnprotectedMediaFreq=TimesPerDay
# default: 1
# limit: 1 <= DeleteUnprotectedMediaFreq <= 24
# This period is used to run unprotected media deletion operation.
# If set to 1, operation is performed once per day (00:00),
# set to 2 two times per day (00:00,12:00), set to 3 three times
# per day (00:00, 08:00, 16:00), set to 4 four times per day
# (00:00, 06:00, 12:00, 18:00). If maximum (24) is specified,
# operation will be started every hour.
This same task can also by run manually at any time using either the command line interface:
omnimm -delete_unprotected_media [Library | -all] [-force]
or can be executed from the Data Protector GUI:
Devices & Media -> Right Click on Device -> Delete Unprotected Media
By default media that has expired in the last 24 hours will not get purged. This behavior can be changed by
editing the GLOBAL file and adding / editing # DeleteUnprotectedMediaMinimumAge
