Overview: Advancements in technology and cost reductions have recently made it possible to use disk together with tape to improve data protection. With decreasing backup windows and increasing amounts of data, users are adding more tape drives and implementing faster backup network topologies, including Storage Area Networks (SANs). The administration and ongoing management would be complex and inefficient. In this type of environment, backup to disk can help. In any case, it is well worth the time and effort to investigate how using disk in addition to tape could potentially give a better backup and restore resolution.
