This is actually not true - they just put a bunch of copies of your data on an external drive. ?The code for the program that manages this is proprietary, if that's what you meant. Still, zfs snapshots are a lot more efficient and faster than Time Machine (about a second for each snap, instead of 30 min in the cast of a Time Machine backup I did today :(
