How do you setup the tape backup manager to do a unattended backup. I can get it to do a on demand backup but it does not back up with a schedule. The media size on the setting goes automaticly to zero and it says it cant open the tape unit or something like that. I can go in and manulaly get it to do a tape backup if I put in the media capacity in the settings but the setting will not stay in system. I need to find a way to set it up and for the system to keep the settings.
