Hi,
We are taking backup of SharePoint 2010 with DPM 2012 SP1.
The daily recovery points failed of SharePoint with error.
The VSS application writer or the VSS provider is in a bad state. Either it was already in a bad state or it entered a bad state during the current operation. (ID 30111 Details: VssError: The writer experienced a non-transient error. If the backup process is retried, The error is likely to reoccur. (0x800423F4)
I have restarted “SQL VSS Writer service” on SQL server where the SharePoint databases is hosted.
And sometimes I get Last error: No error , and sometimes get Last error: Non-retryable in 'SqlServerWriter”. When run “vssadmin list writers” on SQL server. But still the backup failed even if all VSS writers are stable on SQL server.
I have check event log on SQL server during the backup failed and get following error“Error message: Database 'RollbackSnapshotTempDB{3AEDCB94-0E03-412E-BD48-60C82192CE6B}' cannot be upgraded because it is read-only or has read-only files. Make the database or files writeable, and rerun recovery.”
Its really difficult to find wheather its DPM, SQL or SharePoint error,
Any help would be highly appreciated.
