I have done something similar (but with less data). How big of a delta is there per hour? Are you running snapshots?
ndmpcopy works well (to an extent) for doing this sort of thing, as it updated the dumpdates file on the filer and uses it to do its thing.
I have usually resorted to doing a cpio between filers. Using the gnu version of find, the "older/newer than" timestamp args work correctly, so doing incrementals becomes less painful. Of course, this does not deal with deletes.
rsync is nice (http://samba.anu.edu.au) since it is fast, can use ssh (if you are doing this over the open networks), it deals with changes well and does not send entire files (as rdist does).
I would talk to your NetApp sales rep about this, as they may be able to answer questions I cannot :)
Hope this helps.
