This was not entirely clear to me, to say the least.
It seemed that the native Windows Server Backup feature in Windows Server 2012 had added support to backup Hyper-V VMs running on the local machine. But alas, this is not the case when these VMs are stored on a CSV volume.
See this table on the article about Windows Server Backup in Server 2012 on technet:
Support for backup of Cluster Shared Volumes (CSVs) :
Limited support for backing up CSVs as follows:
- - 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
And indeed, when trying to backup a VM running on a CSV on my Windows Server 2012 machine, i got these errors:

So, no dice
