An error occurred while accessing Microsoft Exchange Server

Hi!

We are getting the below error while backing up Exchange 2003 installed on a windows 2003 Server. The server is fully selected in backup job.

"Microsoft Site Replication Service" is not snappable. Attempting to back up directly from the source volume.

Arrow error occured while accessing Microsoft Exchange Server. Check the application event log on the Exchange Server for more Details.

Warning: \\mailserver.domain.com\Microsoft Site Replication Service\SRS Storage\SRS MDB is a corrupt file. This file cannot verify.
