We do backupsets regularly and I set up some customers' servers for backup sets. It's much easier to understand for them to handle only one tape instead of backup data tape _and_ db backup.
We use manual DLT drives, too. I found I had to wait for the server to produce the mount request before the tape was recognised in the drive; the server just waited for the tape to be mounted though it was already in the drive. Your specific problem: Where is the data that's going to be copied to the backup set coming from? Is this the same tape drive / device class you are using to write? You can't read _and_ write using a mountlimit of 1. Thomas Bleicher Netzlink Informationstechnik GmbH
