Hi there!

I don't believe this is possible.  bigasm uses NetWorkers
file backup protocol to store a virtual file, made up of sequential
numbers stored as ASCII, to the server.  Since the data comes directly
from memory, the performance of the filesystem is eliminated as a
performance variable.  Also, using a sequential count as the file data
allows the file to be verified during restore testing.

Because it uses the file protocol directly, I do not believe
it will work in an NDMP environment.
