NDMP: Avoid, avoid, avoid.

I've elaborated on this opinion in the past, but the succinct summary
is that NDMP turns all your fancy TSM infrastructure into a big
remote-tape structure.

Only the very most recent and fancy NDMP clients even give TSM any
sense of the contents of the data.

You have to come up with device drivers on all your NDMP clients.

Ick.  Assiduously investigate other options before discarding all the
advantages TSM gives you.

I spent years doing rmt on unix: I don't want to go back, and you
don't want to go there.
