Capacity Optimized Storage is ideally suited for disaster recovery applications. By reducing data volume, deduplication enables efficient bandwidth utilization for automatic WAN vaulting of backup data to disaster recovery sites. As the term implies, “WAN vaulting” delivers cost-effective offsite storage capacity similar to the physical “vault” where backup tapes are stored, but with immediate accessibility via the network.

By vaulting backup data across wide area networks, the operational inefficiencies and risks associated with tape based disaster recovery are solved easily and effectively, at the absolute minimum WAN cost. The local tape autoloader can simply be replaced with capacity optimized disk-based storage to provide local recoverability that is highly reliable. Backups can be replicated to a central hub site or sites, where a larger system can store the replica backup data for several remote offices. Once the data has been written at the hub, it can then be moved to physical tape as required for archiving.


A variety of topologies are in fact very easy to design and deploy, once backup data is reduced via deduplication and compression technologies for WAN vaulting. Disk-based backup appliances can then replace the tapes and trucks.
