Responding to your overall situation, someone recently posted on this list a very clever way to move a large database to a new server with minimum downtime. As I recall, i t involved moving the data, then using snapshots to keep the new copy syncronized until you are ready to cut over. Unfortunately I didn't keep a copy of this method. Perhaps someone else on the list kept it.
