Windows Server Backup in Windows Server 2012 has feature been changed or added, which include limited support for CSV backup :
- Virtual machines hosted on CSV’s cannot be added as part of backup configuration
- Windows Server Backup has to be configured on all nodes to ensure that backup and recovery will be available in the event of a failure on one of the nodes in the cluster.
- Volumes recovery not supported
- Security access control lists are not applicable on CSV file service root. Therefore, file recovery to the root of CSV volume is not supported.
