This parameter specifies the expiration period for the tape volumes.
Syntax: expir_period = <days>
Required values: Indicate the period (in days) for which the tapes to be used for the backup should be locked by entering a whole number.
Before BRBACKUP or BRARCHIVE start the backup to a volume, the system checks whether the expiration period set by expir_period for this volume has expired.
