Abstract
A method for offloading volume space reclamation operations to virtual tape systems is disclosed herein. In certain embodiments, such a method includes writing instruction information to a virtual tape system for use in performing a reclamation operation on a source virtual tape volume. The instruction information identifies the source virtual tape volume as well as valid objects in the source virtual tape volume. The virtual tape system then transforms the source virtual tape volume by retaining valid objects in the source virtual tape volume, removing invalid objects in the source virtual tape volume, and updating metadata associated with the source virtual tape volume to reflect changes made thereto. This generates an updated source virtual tape volume of reduced size. A corresponding computer program product and system are also disclosed and claimed herein.
