Not sure if I just did not see it before or if it is new with 7.x

but I was making a new dataset and spotted this Plugin type  "Windows Cluster File Server"

Now I have a lot of Windows clusters

and I was instructed on how to back the up.

the Physical node has a Group that backups the C drive and the VSS

the virtual nodes get their own Group that backups up the drive associated to that node.

Both of these I choose window file system and specify the drives.

So when would you use this Plugin type?
