ABSTRACT:
A method and system are described for recovering data from an unreliable tape within a tape server which includes a plurality of tape drives, a direct access storage device, and a storage manager. After the storage manager is queried for a list of all volumes that have been written to the unreliable tape, a status of a volume on the list is determined. The volume is written onto the direct access storage device from the unreliable tape where indicated by the status of the volume, and the volume stored on the direct access storage device is made to appear to be a new version of the volume where indicated by the status of the volume.
