During my weekly full backup the fourth job in the series never completed, I had to cancel the job after it had been running for 52hours. The first three jobs completed as normal. All settings for the jobs are to the weekly media set and to "Append to media, overwrite if no media is available"
In job monitor as the job was running it had the yellow question mark, however no alert box had appeared.
When I view the job log it simply says "Mount failed" and "Job cancelled by user"
This error is frustrating for me because all other weekly full backup jobs that had been scheduled as well as the next day's jobs were unable to execute due to the fourth job occupying the tape changer.
Can anyone offer help?
