        Debbie,
        You can update the devc mount retention without halting the
        server.

        The number you choose depends on the situation. For example
        if you have many clients being backed up one after the other
        it is advantageous to have the tapes already mounted and ready
        so a higher number would be good.

        However if you run backups with large gaps of time in between
        them, then you may want to ensure that no tapes are mounted.

        We at BT use 15 minutes mount retention time, it seems to work
        for us O.K.
