Interesting, I originally thought of ZFS too, but I didn't realize the 
Linux port was working 100% yet.  Is it?

It's still just a "snapshot", not a fully "time journaled" filesystem, 
and LVM2 could do snapshot type things also... but I like the ZFS syntax 
and setup better, just a personal preference.  Neat stuff.
