How CA ARCserve Backup Balances Drive Usage

CA ARCserve Backup balances tape drive usage by rotating the usage of tapes evenly between all tape drives in your library. When CA ARCserve Backup starts a backup job, it detects the last drive used and uses the next available drive in the library.

To minimize the movement of tapes from tape drive to tape drive, CA ARCserve Backup performs the following analyses and actions:

• If the media targeted for the job is loaded, allow it to remain in its current drive and run the backup job.
• If the media targeted for the job is not loaded, identify the last used drive and load the tape into the next available, empty drive, and then run the backup job.
