working-copy is on my workstation copy 2 is on my online fileserver (xeon with ecc cache, ecc ram, zfs doing regular scrubs in zraid3 for 3 disk fault tolerance) I do semi-regular snapshots of the ZFS filesystem. copy 3 is on offline, powered down and disconnected fileserver (connected once every few months, to sync with fileserver, also zfs, but only 1 disk fault tolerance) This is not quite by the book, since there IS a window where both fileservers are powered on at the same time, the risk is somewhat mitigated by them being in two phyiscal locations.
