If NFS is the only way to access the data, then I suppose it's your
only choice. I suppose if there was a machine closer on the network
than the destination you might win by mounting the NFS volumes there
and then using rsync to the final destination.
rsync should still be a considerable win over plain copying, since it
can be smart about timestamps and so on.

It entirely depends on your requirements for mirroring. If you want
daily backups, then run daily. If you need less than an hour's lag,
then you may need to rsync several subdirectory trees in parallel.
Hope that helps,
