Cannot perform NAS NFS/CIFS incremental backup operation using snapshot difference on the mounted or mapped volume due to one of the following reasons: 1) The volume is actually a qtree. 2) The volume is not a full volume, it is not mounted or mapped to the root of the volume.
Processing stops.
Retry the incremental backup operation by specifying an entire NAS NFS or CIFS volume.
