Abstract
A virtual tape library management system provides multiple, simultaneous accesses to the content stored on a single virtual tape. The virtual tape library management system receives a first request to access the content of a virtual tape. Responsive to the first request, the virtual tape library management system provides access to the virtual tape. While the virtual tape is being accessed, the virtual tape library management system receives a second request to read the same virtual tape. In response, the virtual tape library management system creates a shadow virtual tape corresponding to the virtual tape, maps the shadow virtual tape to the content of the virtual tape, and provides access to the shadow virtual tape.
