Abstract
A method for selectively controlling reutilization of data space in a virtual tape system is provided which allows a user to designate whether data from a scratched virtual volume can be automatically deleted without any further action on the part of the user. This allows a user to selectively choose to create a safety net by which expired data could still be retrieved if so desired, while also minimizing the impact of such a safety net feature on the overall efficiency in space management otherwise provided by the virtual tape system.
