No, going from SP<>APM<>SP as mediated by the FP.

Well, Legato's got some documented stuff. Auspex doesn't. Like
I said in my mail, I don't really know Amanda really well, and
if it works for you great.
I really only meant that the data path performance issue meant
that putting backup filesystem hooks into the FP would be the
right thing to do- but that's from the perspective of working
with all of the software and not thinking about portions of it
being 'hidden'... Sorry...
><lots of Auspex bashing snipped out>
Well, sorry. I, for one, would have been glad to see the interfaces
published. Actually, I believe that most of the interfaces could
have been inferred from some include files, but I can't really remember.
