database backup expiry, but if you have not licensed it, you must delete the volume history yourself. Use the delete volhistory command to do this. We recommend deleting any database backups that are older than seven days. The delete volhistory command will never delete the current database backup, so we use "today-6" when specifying the "TODate" option. The two recommended schedules are DELETE_VOLHIST and BACKUP_VOLHIST. DELETE_VOLHIST We define a schedule to delete volume history, called DELETE_VOLHIST, specifying a type of TYPE=DBBACKUP, as shown in Example 12-6. Example 12-6 Defining the DELETE_VOLHIST schedule tsm: LOCHNESS_SERVER1>define schedule delete_volhist type=admin cmd="delete volhistory type=dbbackup todate=today-6" description="Delete volume history information for database backups" starttime=07:00 active=yes ANR2577I Schedule DELETE_VOLHIST defined. tsm: LOCHNESS_SERVER1>q sched delete* t=a * Schedule Name DELETE_VOLHIST Start Date/Time Duration Period Day 02/20/2006 07:00:00 1 H 1 D Any BACKUP_VOLHIST Some operations, like the delete volhistory command, do update the volume history in the server database, but do not update the external volume history files. To ensure that the external volume history data is current, you should schedule a daily volume history backup using the backup volhistory command. Example 12-7 shows how to create the schedule. Example 12-7 Defining the BACKUP_VOLHIST schedule tsm: LOCHNESS_SERVER1>define schedule backup_volhist type=admin cmd="backup volhistory" description="Backup volume history file" starttime=07:05 active=yes ANR2577I Schedule BACKUP_VOLHIST defined. tsm: LOCHNESS_SERVER1>q sched backup* t=a * Schedule Name BACKUP_VOLHIST Start Date/Time Duration Period Day 02/20/2006 07:05:00 1 H 1 D Any Chapter 12.
