I've been using unison (
lately, rather than rsync. You don't really need it, since it's
two-way and you're going one-way, but it's kind of easier to use than
rsync so you might want to look into it. There are packages in extras
and it's available for CentOS, too, which I saw was already
recommended (in its OpenFiler form) in another post.
