High Availability and Disaster Recovery Features in Microsoft Exchange Server 2007 SP1
Microsoft Exchange Server 2007 SP1 provides new disaster recovery features and availability options that help businesses to effectively meet their site-resiliency requirements and protect their messaging systems against failures. Administrators should carefully evaluate the level and type of availability required before deciding which option is most appropriate for their environment. The choice of a particular option will depend on various factors such as cost, downtime, geographical redundancy, recoverability, scalability, and manageability. Implementing the required availability and disaster recovery features, and configuring them for optimal performance can help create flexible, highly available systems in enterprise data centers.
