Yeah, thought it might be this. Sorry I wasn't more clear initially about the use case. Basically, the production server is in a datacentre and the reserve server is on a very fast vdsl service. The reason for the reserve server is, if the production server fails then I swap DNS to point at the reserved server and the guests on it without interruption of service. All guests are running databases (mysql) though they aren't especially busy. So I guess the best bet would be mysql replication for the databases and rsync for everything except mysql? thanks everyone who took the time to answer -- J.
