This is the weirdest thing. I'll put the tape in to be backed up before I leave for work. The next day it hasn't finished backing up for that night and asks me to put reuseable media in. I put another tape in. After a few hours it tells me to put the tape that was just in it. Once I do that, it seems to back up the system just fine. How can I get it so I don't have to change the tape 3 times a day.
