Cannot backup to tape with backup exec 2012
So I've been trying for more than a week now to backup to tape with backup exec and I'm close to abandonning this program. I always get the same error message : "Physical volume library drive not found". I tried a few things on the net like reinstalling the tape drivers, updating the firmware, running as administrator. It seemed to me like people were saying that the tape driver doesn't work. So I tried installing Uranium backup in trial version and could create a backup that works with my tape right away. So what is the problem with backup exec?
