I'm trying to get a distributed Umbraco solution to work. We have a main server in one location, complete with web and db server. For failover we have a backupserver in another location, also with its own database.

How can we make this setup work? It seem the biggest problem will be Umbraco not replication the content...

SQL server mirroring seems to be the only solution - but is it fast enough? it´s no use if the backup server refreshes its cache before the changed data has been replicated...
