State Replication is the simpler of Talon's 2 High Availability models. With State Replication Talon replicates changes to state and the outbound messages emitted by your application's message handlers. In the event of failover to a backup or a cold start recovery from a transaction log your application's state is available at the same point where processing left off, and the engine will retransmit any outbound messages that were left in doubt as a result of the failure.
