NDMP as used today doesn't specify a file format, but leaves it up to
the device.  For your purposes though, the answer is yes.  All NDMP
backups of a Network Appliance filer will use a dump serialization.
(Other devices can use very different formats).

While the stream is a pretty standard netapp dump, NBU will write extra
information to the tape to identify it.  I don't think you can just hook
up an tape written via NBU, type 'restore' and expect it to read it
properly.  At a minimum, I'd think you'd have to forward the tape to the
correct file, then skip past the NBU header.  I'm not sure if you could
do that step again on later volumes if the image spans tapes.

This forum post talks about steps to use 'ufsrestore' on a Solaris
host.  I would assume similar steps would be required to use 'restore'
on a filer.
