Since upgrading to DPM 2012 SP1, we are experiencing a high rate of recovery point failures backing up our Exchange 2010 SP2 CU5-v2 DAG to disk. These backups are run against a replica DB, not the active DB. The error description form DPM is:
On the DAG node, the corresponding event is:Description: Recovery point creation jobs for Exchange Mailbox Database <DB1> on <DAG node> have been failing. The number of failed recovery point creation jobs = 3. If the data source protected has some dependent data sources (like a SharePoint Farm), then click on the Error Details to view the list of dependent data sources for which recovery point creation failed. (ID 3114) DPM encountered a retryable VSS error. (ID 30112 Details: VssError:The writer experienced a transient error.
If the backup process is retried, the error may not reoccur. (0x800423F3)) Recommended action: Check the Application Event Log on <DAG node> for the cause of the failure.
Fix the cause and retry the operation. For more information on this error, go to http://go.microsoft.com/fwlink/?LinkId=132612. Create a recovery point...
The Microsoft Exchange Replication service VSS Writer (Instance c019906b-b192-4f9e-8fa2-85376f166961) failed with error FFFFFFFC when processing the backup completion event.Overall the DPM server also seems very sluggish since the upgrade. We are periodically receiving SCOM heartbeat failure alerts and when you try to login when you receive these alerts the server is clearly bogged down. When you look at the system resources though, CPU is low, memory is OK. I am looking for any assistance on the possible cause or steps that can be used to troubleshoot this at a low level.
