Alex, Yes snapshots are online and yes they do store diffs, but only after the first snapshot which by definition has to copy everything.
As to the question of how frequent to run them, that really depends on your tolerance for loss. The added operational costs are reads from disk and bytes sent over the wire. You can tune this behavior with max_snapshot_bytes_per_sec [1].
