I am using Backup Exec 12.5 with a Quantum multiloader 3 it is a 16 bay backup drive. I am having a problem with media tapes changing media sets which means the backup jobs are written to incorrect tapes. I keep manually associating the media with the correct media sets at the moment and would like to make sure media stays in the correct set. All tapes are labelled with a bar code which associated with the media on Backup Exec however media keeps changing media sets.
Does anyone know how to resolve this?
