Set a backup policy for using tapes. To do so, use a combination of a tape backup management class and tape backup policy.
The tape backup management class defines the operation rules for backup destination storage pools.
Define the following:
Generation management storage pool name
The name of the storage pool used to store backup data that is managed with the number of preservation generations specified.
Number of preservation generations
Set the number of generations of backup data that should be preserved.
Day management storage pool name
Set the name of the storage pool used to store backup data that is managed with the number of preservation days specified.
Preservation days
Set the number of days that backup data should be preserved. Set the number using "11.2.1.11 acmtpmgmtclassset (Tape backup management class setting command)".
Define the following:
Tape backup management class name
Specify the name of the tape backup management class to be used.
Number of days (interval)
Set the number of days between required backups.
If the number of days after the last backup is exceeded without a backup being executed, a delay message is displayed.
Backup is not executed automatically, even if the number of days between backups is set.
Set the number using "11.2.1.8 acmtpbkpolset (Tape backup policy setting command)".
