Mirroring/Replication

Don't mistake availability with recoverability – be sure your high availability systems are also rapid recovery systems.

Simply put, mirroring, or replication, is the process of creating redundant copies of disks or disk files. It has become increasingly popular as a high availability or business continuity solution for many large enterprises that require uninterrupted processing for their business systems. In the event of an unplanned outage, a current or near-current copy of this data is safely tucked away on the redundant disks, usually at a remote location.

Because of their inherent recovery capabilities, our solutions are the perfect complement to mirroring or replication technology. They work to reduce mirroring and replication costs by identifying the business-critical files—usually some 40 to 60 percent of files are required to maintain high availability—you need for disaster recovery. This helps you limit mirroring costs by aligning the protection of non-critical data with your standard backup procedures.
