As the title says, we're having trouble getting Backup Exec to overwrite data on our tapes.
In the properties of the backup job, the option to "overwrite media" is clearly selected. However when the job runs, it goes for the maximum 12 hours and doesn't grab a single byte of data.
The temporary fix we've been using is to manually perform a quick erase on the media when it's swapped out in the morning. When we do this, the backup runs perfectly that night.
Not a huge problem, but it's one that doesn't make sense and therefore bothers me. Any ideas?
