Disaster recovery configuration for Exchange
A Disaster Recovery (DR) configuration enables you to restore application data and services in the event of a catastrophic failure. A typical DR solution requires primary and secondary sites, and clusters within those sites. The cluster at the primary site provides data and services during normal operation, and the cluster at the secondary site provides data and services if the primary site fails.
The following figure illustrates a Disaster Recovery configuration.
The illustration displays a disaster recovery configuration in a NetApp storage environment. In this case, the primary site is replicating its application data to the secondary site.
When a failure occurs, such as an earthquake that destroys the data center in which the primary site resides, the DR solution is activated. The data that was replicated to the secondary site is used to restore the application services to clients.
