Rsync working natively is very efficient, but think about what it has
to do in your case. It will have to read the entire file across nfs
just so rsync can compere contents and decide not to copy the content
that already exists in your backup.

I'd try rsync over ssh first, at least if most of the files do not
change between runs. If you don't have enough ram to hold the
directory listing or if there are changes to a large number of files
per run, tar might be faster.
