I have a Win2k3 SP1 server running SQL 2005 SP1. I have installed the remote agent, without AOFO. We have the SQL agent license. The job that we run does have the "use AOFO" setting turned on as we have a different machine that uses it.
While backing up the machine, the agent on the SQL server unexpectedly quits. I have turned on debug logging on the agent and it doesn't even show an error on the debug log. It seems to quit while it is in the process of sending the temporary SQL dumps to the backup server. The dumps themselves are all created OK.
I have removed and reinstalled the remote agent several times, this has not helped. I am able to successfully complete a smaller test backup (with its own selection list that doesn't have all the DBs) without the agent crashing.
This is NOT exclusive to 11d. It started happening a week or two ago on 10d, and then we got the upgrade notice for 11d so I figured I should upgrade to see if it would resolve the issue first. We're running 11d now though, so I'm posting here.
