Abstract

The present invention includes a system for simulating the performing of data storage operations. The system may include a storage manager component, at least one media management component directed by the storage manager component to manage storage operations to at least one storage device, and a storage emulation module adapted to simulate the characteristics of the at least one storage device. Under the direction of the storage manager, the emulation module may be adapted to simulate storage operations to one or more storage devices performed by one or more of the media management components.
