Your question assumes a strong relationship between BACKUP DB and BACKUP STGPOOL, but there is no such relationship. BACKUP STGPOOL creates a (point-in-time) logical mirror of your primary storage pools. Copy storage pools are not only for disaster recovery, but can also be used to recover primary storage pool volumes in the event of a primary pool volume failure. BACKUP DB represents a point-in-time snapshot of your TSM database. There is no direct relationship between the tapes created by BACKUP STGPOOL and the tapes created by BACKUP DB. Thus the deletion of the BACKUP DB tape has no effect on your copy storage pool volumes, just as there is no effect on your primary storage pools. As backup and archive versions expire in your primary storage pools, so they will expire in your copy storage pools. Use reclamation to avoid the "never returning tapes" problem.
