I would say your EMC support org. needs to figure this out at the block
layer. They could see block changes and replicate them to the remote filer.
NetApp has a great feature called SnapMirror which I've used in the past
to keep various NFS filers in sync. It works great since it only syncs
block-level changes in WAFL.
