We are taking daily backup using BRMS. Two days before because of one application failure on server, we have cancelled backup. The tape for that backup was moved to tape library. When problem resolved, we inserted new tape for backup. Suppose old tape is X and new tape is Y. But, it took X tape for backup instead of Y. Both the tapes location was tape library. Both the tapes were expired. Why it took X tape insteads of Y?
