VDP 5.5 - Network Copy Support?

Hi There,

I've been working with VDP 5.5 recently and have a question regarding backup copy methods -- I know the typical method for backup is that the VDP appliance hot-adds the VMDK's of the backup source to the appliance and performs the disk copy, but was wondering if there's a network-copy fallback if hot-add is not possible. 

If network copy is actually supported, is there a way to force this as the primary backup method?

Thanks!

D.
