I have been having this random job failure. It started occurring as of BE 2012 and currently I have BE 2014 with service pack 2 installed. It only appear to occurred with our exchange backup job and to this particular mailbox. However, the strange thing about this is that the job going to Disk will always be successful, but when it duplicate to Tape it would sometime get the following error message.
Job ended: Thursday, January 29, 2015 at 5:31:59 AM
