Rory, James,
I appreciate your help, I will look into these suggestions.
Our habit here has been storing tapes off site. Being the only place I've
worked, I've assumed that this is a common workflow.
Since there's a bit of fuss involved in order to automatically unmount and
mount, I'm thinking that our procedure is not as common as I assumed.
Is off-site tape storage not a typical requirement?
Thanks,
Kent
