    Hi All,

    I have 2 servers in a failover cluster Running Windows Server 2012 attached to a FC SAN using Cluster Shared Volumes

    My question is "Can 'Windows Backup' backup virtual machines running in this environment"

    Simply running Windows backup on the server fails with "Windows Backup cannot backup an application with files on a CSV volume."

    I am currently using Altaro HyperV backup trial on both nodes, this works brilliantly but I would like to know if ANY level of backup can be achieved without any such 3rd party software.

    I note this same question has been asked but not answered on a different thread here - http://social.technet.microsoft.com/Forums/en-US/winserverhyperv/thread/dfd4f6ee-2f16-4ca4-ad84-89c86cdb448e

    Hi,

    There are two common methods to backup information that is stored on Cluster Shared Volumes in a failover cluster: virtual-machine based backup and management operating-system based backup. Management operating-system based backup is sometimes called parent-partition based backup.

    CSV itself do support back up, but Windows Server backup in Windows Server 2008 R2 or previous version doesn’t support CSV backup.

    Windows Server backup in Windows Server 2012 has feature been changed or added, which include support for CSV backup (more accurately, limited backup):

    1. Virtual machines hosted on CSV’s cannot be added as part of backup configuration
    2. 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.
    3. Volumes recovery not supported
    4. Security access control lists are not applicable on CSV file service root. Therefore, file recovery to the root of CSV volume is not supported.

    Windows Server backup in Windows Server 2012 include  limited support for CSV backup. On two node Hyperv cluster (windows 2012) you could do file backup with wbadmin tool. VM should run on the same host as backup job.

    wbadmin start backup -include:d:\ClusterStorege\volume1\server1 -backuptarget:\\localhost\vmbackup\server1

    you cold do recovery VM to alternate location

    wbadmin start recovery -version:05/22/2013-06:25 -backuptarget:\\localhost\vmbackup\server1 -itemtype:file -items:d:\ClusterStorege\volume1\server1 -recursive -recoverytarget:x:\recover -machine:hyperv1
