Yes, snapshot operation of the Farm backend store is on node basis. We just send an cluster-wide message that request for snapshot operations on each node. Currently, Farm doesn't support *live* snapshot, so it safe for us to do a cluster-wide snapshot without on-the-fly IO requests. And those snapshot objects are distributed on each backend store.
