AFAIK, that would be the case in theory.  The same thing applies
when it comes to NDMP cloning.  In practice, it could be perhaps
possible to even make it work, but I guess the amount of possible
gotchas makes it completly unsupported and out of the question at
this time.

My assumption would be that to have two different filers by
two different vendors running together in terms of directed
restore they would need to use same dump mechanicm on each
filer target to be completly compatible and you same approach
to read it.  If you have right now two different filers, you
test it by logging on one and make some dump on tape and then try
to read it on second one.  The same happens with NetWorker - he's
just here to say which tape is needed and here you will do that
manually.

For the disaster recovery thing hard, but you could always try
to make backups over the CIFS/NFS from time to time and I guess
restore of those over the another CIFS/NFS could work, but this
also too risky and full of unexpected gotchas (and that's the
last thing you want when you really NEED restore).

Cheers,
