Protecting Data Stored on a NAS or SAN Infrastructure

In a short span of time, NAS devices have taken the lead as the preferred backup destination by small businesses. As an affordable storage solution, they offer a way for organizations to “drop in” additional network storage with relatively minimal effort, often with built in redundancy. And scale-out NAS appliances use an architecture that lets companies grow by adding clustered nodes, for increased capacity and performance.

The downside of the traditional NAS backup approach is the inability to scale beyond the inherent limits of the system. A NAS has a preset amount memory, CPU horsepower, drive slots and data throughput. Once it reaches capacity, options become limited. While purchasing additional NAS appliances, which are each managed separately, works fine for small businesses, this approach may become unmanageable for large IT environments.
