The failback steps are different,
and are covered in the next section.
Another key new feature introduced in Service Pack 1 is the ability to replicate transaction log files over
different networks. In the RTM version, only the public interface was used during normal replication.
This setting is controlled with the ReplicationNetworks parameter. The parameter can be set to
PrivateOnly , PrivateThenMixed , or AllNetworks :
Set-MailboxServer -Identity mb100ccr -ReplicationNetworks PrivateThenMixed
If the mailbox servers are connected with a cross - over cable, this can save significant traffic from the
public network.
Failover in Standby Continuous Replication
Like LCR, Standby Continuous Replication is not an automated failover. SCR is meant for significant
failures, not routine maintenance or other smaller outages. The steps are very similar to LCR, except the
recovery is to a standby server using the database portability feature of Exchange Server 2007. Because
the server name changes, it impacts all Outlook clients. Office Outlook 2007 clients will automatically
reconfigure their profiles with Autodiscover, but older clients may need to be manually updated.
The process is different if failing to a single server or a CCR cluster. First are the steps used to activate the
passive node on a single SCR target.
