Backup may have caused Mail store to unmount
First the basic information: I am running Backup Exec 12.5 Rev 2213 with Service Pack 4 on a Widnows 203 Enterprise SP2 server. The Exchange server is a Windows 2003 SP2 server also. I am running Exchange 2003 ver 6.5.7638.1
Saturday night I had a full backup of the Exchange server running when the Mail Store 1 was unmounted, and the error 1159 showed up in the Event Log. This is the error whereby the transaction logs hit a 1008 maximum and then automatically unmount the store. According to Microsoft forums, this could be caused by the backing up of the server. I have the default settings on my full back up, which should handle the transaction logs created. Is there something else I need to do to prevent this from happening again. It's the first time it has ever happen, although of late I have had issues with the backup failing because it could not access the directory. I have been backing up each mailstore to a new disk set, and the access problem appears to have been solved. The backup I ran on Saturday was the old job, now pointed to the new disk space. Should I delete the old job and setup a new one? Attached is the job log from the failed backup.
