Normally I'd suggest rsync. It's made for that job and it runs over an
encrypted link. It's "smart" in that it only copies changes and it can
compress for use across slow links (though I doubt you care). 

I use to make regular updates of our backup configuration management
system data at a remote location and have always had excellent
results.

The reason I am a bit uncomfortable is that V2.5.0 just came out and it
seems very flaky. I suspect a new, bug-fix release will follow soon,
but, for the moment, I'd suggest installing an older release, possibly
from about 2 weeks ago.
