Retensioning a tape
Before you run a backup job to a tape, you can run the tape in the tape drive from beginning to end at a fast speed. Retensioning helps the tape wind evenly and run more smoothly past the tape drive heads. Refer to the documentation that came with your tape drive to see how often to run this operation.
This operation is only available if the tape drive supports retensioning.
