If a device fails while a job is running on it, that job is rescheduled and placed on hold. Setting up device pools offers the following benefits:ĭrive pools provide automatic job rescheduling. Targeting a job to this drive pool (Pool1) rather than targeting the job to an individual device will provide fault tolerance and maximize hardware efficiency. When a drive pool is created using multiple drives, a single virtual device (Pool 1 in this case) is formed. Friday night the Accounting-Job took the lead and went to the Firewire, but Sunday AM the Databases-Job took priority and pushed that day's Accounting-Job to tape media.ĭevice pools can consist of standalone drives, drives in single or multiple drive robotic libraries, fixed backup-to-disk folders, and removable backup-to-disk devices.Ĭreating drive pools overcomes the limitation that arises when using the same drives individually.Ī drive pool is a collection of multiple tape drives in a single pool. I've always used Drive Pools for Fail-over, Load-balancing and when we had Fire-wire drives mixed with Tape-Media and USB drives it would let you prioritize based on the Job.
