NBU 7.6.1, vSphere 6 and NFS 4.1 support

Hello,

We are setting up a new vSphere 6.0 infrastructure with new NetApp NFS volumes (array is a 8060 in cDot 8.3) mounted with NFS 4.1.

So I have added my new VC in NBU. Then I tried to backup a VM on my new Datastore and got the error:

Error nbpem(pid=24969226) Invalid, unsupported or disconnected datastores for VM name = [VM_NAME], server = [vCenter Name], datastore(s) = [My NFS 4.1 Datastore]

I tried to back up a VM on a local ESX datastore and here it's working perfectly.

So did anyone succeed to back up VMs on vSphere 6 running on NFS v4.1? Is it supported? Found nothing is the documentation.

Thanks for your help or feedback.

Renaud
