We have a tape library and we insert 2 tapes for during the week and 2 for the weekend. I have configured Symantec with Media sets of Daily, Weekly and Monthly
The backup is running daily flawlessly until Thursday when one of the tapes becomes full in the middle of the backup process. At this stage Symantec throws up an alert to "Please insert overwritable media into the robotic library using the import command."
WELL, since there IS a blank tape available within media set "Daily" I don't understand why it doesn't automatically move on to the next tape when the media becomes full in the middle of the backup process.
HOWEVER if I cancel the job and start it again immediately it continues to use the other bank media which it failed to write to when the original media became full.
