You are cloning a save set in NetWorker. There is one appendable clone volume available. However, the clone operation is not using this volume and is asking for a new volume to be mounted.
What may be the cause?

A.
Clone volume has an earlier clone of the save set

B.
Source volume has an earlier clone of the save set

C.
Entire cloned save set must fit on the clone volume and there is not enough room

D.
Source volume is being used for another clone operation
