Cause
During snapshot processing in a backup job, the Remote Agent crashes on the Sharepoint Server.
Remote Agent crashes with an unknown faulting module.
This issue can also be caused due to a conflict with a non Microsoft VSS provider other than Backup Exec's VSS provider. For Example: Acronis.
Solution
Make sure the Remote agent is updated.
This issue can occur if the ServiceDll registry value for Swprv is missing or incorrect. Follow the Microsoft article: http://support.microsoft.com/kb/2009513
Disable any non-Microsoft VSS providers that are in use other than the Backup Exec VSS provider.
