We have several stages to our daily backup schedule. Exchange goes directly to tape, while two separate media servers backup file and application servers to disk. Then a duplicate backup set procedure backs up those disk sets to tape, we only have one tape drive, with a changer holding 16 tapes. In order to most efficiently use my backup resources, I would like to split up my jobs over the course of the night, so that the tape unit isn't sitting idle waiting for a backup to disk process to complete. Two questions, can two backup to disk jobs happen simultaneously on the same media server? Secondly, I would end up with 4 or 5 duplicate to tape jobs which could potentially use 5 or 6 tapes in a night. Is there any way to force two different jobs to use the same tapes, provided there is enough space on the tape?
