Backing Up Backup Sets with RMAN
Use the BACKUP BACKUPSET command to back up backup sets produced by
other backup jobs. This command is especially useful in the following
scenarios:
- Ensuring that all backups exist
both on disk and on tape
- Moving backups from disk to
tape and then freeing the space on disk
Note:
You cannot duplex
backups when running BACKUP BACKUPSET.
RMAN always makes one and only one copy on the specified media when
performing BACKUP BACKUPSET.

To back up backup sets from disk to tape:
- Assuming that you have
configured an automatic sbt channel, issue the BACKUP BACKUPSET command
at the RMAN prompt. This example backs up all disk backup sets to tape:
2. RMAN> BACKUP DEVICE TYPE sbt BACKUPSET ALL;
3.
This example backs up all disk backup sets to tape and then
deletes the input disk backups:
RMAN> BACKUP DEVICE
TYPE sbt BACKUPSET ALL DELETE INPUT;
- Issue a LIST command
to see a listing of backup sets and pieces.
