And if you ever need a two-way sync (ie files on both hosts might change, and propagation to the other host is desired), look at unison.

I've given unison a lot of chances over the years, but I keep going back to rsync with "inbox" and "outbox" directories (if that can be done), or [le]git push/pull/sync if not.

unison is very slow compared to rsync. version at both ends must match (which means you'll likely need to compile your own unless all your machines run the same distro and version).
