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

The last operation failed.
        - Returned HRESULT: 80042313

Cause


Creating a backup set with CSV and non-CSV volumes is not supported.

Resolution


Cluster Shared Volume (CSV) and non-CSV volumes need to be backed up separately.
