Re: Synchronous Replication as backup site...

Yosi

Your thinking is largely correct. What sort of comms line do they have between the two sites? I would normally not recommend using synchronous replication for a real time system, because they normally can't handle any downtime issues. If the network goes across anything less than an internal LAN, I think they need to revisit their thinking.
