The ability to continue to provide a full service to your user community in the event of the loss of a data center is an increasingly common requirement. The use of Cluster Continuous Replication (CCR) with Exchange 2007 is an obvious choice in providing some of the functionality to meet this requirement. One advantage to this approach is that the reliance on expensive storage replication solutions might be reduced. In addition a disaster recovery scenario is managed from within one team rather than several. In most cases the messaging team can manage the restoration of service without the intervention from the storage team, or from a remote 3rd party hardware vendor for example. The use of Exchange Server data replication as opposed to storage replication solutions also gives us more options to use PowerShell scripts to assist administrators in simplifying and controlling service and data recovery.
An example Exchange 2007 design (that flowcharts are based on) using CCR is as follows.
