In your case it'd probably be rsync or whatever you're happy with.

I'm on Debian stable and I like being there for production machines (even though this is a backup machine). I'm not sure about the availability of a 3.8+ kernel on Debian. I'm tempted by zfs but worried about its likely cohabitation -- licence-wise -- over time with the kernel.
