Abstract
A virtual tape storage system includes an original virtual tape library for storing data and includes snapshot virtual tape library (SVTL). The SVTL includes a snapshot of the data stored in the original virtual tape library. A host is operable to receive the snapshot data from the SVTL to perform a disaster recovery test of the original virtual tape library. The SVTL is generated from the original virtual tape library using a copy-on-write snapshot process. In an embodiment, the original virtual tape library stores the stored data on a number of virtual tape volumes (VTVs), and the SVTL includes a snapshot of those VTDs and VTVs which are required for a disaster recovery test of the original virtual tape library. In this case, the host uses the SVTL to perform the disaster recovery test of the original virtual tape library.
