Hi,
We have DPM 2012 backing up some of our VMs, including Exchange 2010 and Exchange 2013. We have never had a successful backup with no errors for the Exchange databases. Have tried:
1. Restarting IIS on Exchange servers
2. Installing Visual C++ on Exchange 2013
3. Dismounting mailbox databases and truncating logs
4. All vsswriter statuses are stable
Error messages on the Exchange 2010 are:
"Event 9782 MSExchangeIS: Exchange VSS Writer (instance f7510d9f-4e76-44ce-8e62-f4f6b262fc7b:5) has completed the backup of database 'Admin Mailbox' with errors. The backup did not complete successfully, and no log files were truncated for this database."
"Event 2007 ESE: Information Store (1780) Shadow copy instance 5 aborted."
Error messages on Exchange 2013 are:
"Event 2038 MsExchangeRepl: Microsoft Exchange VSS Writer backup failed. No log files were truncated. Instance 4da58804-0535-469d-a2c3-6df332dfab33. Database f39b8e25-7a5c-4baf-b4fe-fbe8844fc463."
"Event 2006 ESE: Information Store - Primary Staff (7416) Shadow copy instance 2 completed successfully."
"Event 2034 MsExchangeRepl: The Microsoft Exchange Replication service VSS Writer (Instance 4da58804-0535-469d-a2c3-6df332dfab33) failed with error FFFFFFFC when processing the backup completion event."
Please help. Backups worked fine in DPM 2010. SQL databases are being backed up successfully from same DPM 2012 server.
Thank you.
