As far as I can guess from your description, any problem here would lie
with the NDMP client on that device.  So you'd have to talk to the
vendor of the device.

Networker isn't doing much here.  It's requesting a datastream and
storing it during the backup, and it's sending the datastream back to
the machine during a restore.

It's out of Networker's control how it deals with that data.  (Restores
the data to disk, errors out, panics and dies...)

It's my guess that any such answer would have little to do with
Networker and more to do with the OS/NDMP client on that device.

Have you asked that vendor about it?  Do they say that this should or
shouldn't work?
