A backup job may fail with a CSV and non-CSV volume in the same set on Windows Server 2012

A backup set cannot be created if a Cluster Shared Volume (CSV) and non-CSV volume are included in the same set. Attempting to do so fails with the error VSS_E_FLUSH_WRITES_TIMEOUT after 60 seconds.

For example:

DISKSHADOW> begin backup
DISKSHADOW> add volume c:\clusterstorage\volume1
DISKSHADOW> add volume c:

The last operation failed.
        - Returned HRESULT: 80042313
        - Error text: VSS_E_FLUSH_WRITES_TIMEOUT

Creating a backup set with CSV and non-CSV volumes is not supported.
Cluster Shared Volume (CSV) and non-CSV volumes need to be backed up separately.
