Protecting Data from Failure or Disaster

Applies To: Windows Server 2003, Windows Server 2003 R2, Windows Server 2003 with SP1, Windows Server 2003 with SP2

You must take steps to protect and ensure the integrity of your data. If your organization spans more than one physical site, for example, you might want to cluster resources across sites in what is known as a geographically dispersed cluster. Geographically dispersed clusters maintain high availability even when communication with another site is disrupted or lost. And all server clusters, whether in a single site or spread across two sites, need a plan for backing up application data regularly, and for recovering data in the event of a failure or disaster.

Figure 7.22 displays the process for ensuring the data integrity for your server cluster.
