I have a customer with SBS 2011 and Backup Exec 2010 on the same box.
I have a problem with the Backup Exec - it starts the job backing up the Exchange 2010 Information Store which is around 50Gb. - This is pretty quick but as soon as it finishes the backup job seems to stop - the current progress of the job shows that the source is the MS Exchange Database and the current file is DLLs.
The job does not seem to error - just sits there doing nothing. Have left it for 8 hours and it doesn'd do anything so I have to restart the Backup Exec Services and the job then failes due to a service restart.
Any assistance you may have would be welcomed! I have other clients with SBS 2011 and Backup Exec 2010 and we do not have this problem at their sites. Both SBS and BE are patched to current levels.
