Backup Windows 2012 R2 HyperV cluster node problem

Hi all,

I want to configure BMR backup for one node of HyperV 2012R2 cluser.

When I select BareMetal recovery in WindowsBackup console it checks BMR, SystemState and LocalDisc C. At the end of wizard I got an error: One of source volumes specified has an invalid format and cannot be protected using Windows Backup. Only volumes formatted with NTFS/ReFS can be protected.

I tried to exclude CSV volume from Advanced Settings but still no luck.

Any suggestions will be appreciated.
