Handling this at the device/block level with zfs send/receive, DRBD
etc. is another way to handle the sync.

I had some luck running DRBD across a simulated laggy WAN (using WANEM
to simulate the wan) with a subset of 50 or so hosts being backed
up. The compress cycle after each backup did bog things down a bit
though.
