(1)Overview: Disaster Recovery (DR) plans today are an intricate combination of policies, procedures, operations, and IT systems. The DR plans employed by IT organizations across different regions and types of business are as varied as are the businesses they support. However, there is one fundamental building block upon which all DR plans rest: data accessibility at a second site.
To achieve disaster preparedness, IT organizations require a system that ensures that the mission critical data that the business needs to continue operations is safely housed at a remote site, intact, with data integrity.
The optimal technology to achieve this has long been remote replication. Indeed, IT organizations recognize the central role that data replication plays in a sound disaster recovery architecture, given replication’s ability to get data safely to a remote location more rapidly than alternatives.
This paper describes the native replication feature of ProtecTIER®, IBM’s enterprise-class deduplication solution, and demonstrates that deduplication-enabled replication provides dramatic improvements to Disaster Recovery operations. This enables ProtecTIER to extend the high level of data protection provided by replication to a wider range of data and applications in the data center.
