    摘要: A data storage system stores logical data object(s), each identified by a logical identifier. A control is configured to assign a unique WORM (Write Once Read Many) identifier to the logical data object, and stores the unique WORM identifier as associated with the logical identifier, in a database maintained by the control so as to be persistent. Data storage is configured to write the logical data object with a header with the unique WORM identifier. The control, in order to allow the logical data object to be accessed externally to the control, requires matching the unique WORM identifier in the header of a logical data object to the unique WORM identifier of the persistent database for the logical object. The unique WORM identifier is formed of a checksum hash value related to nonce fields comprising at least the logical identifier of the logical data object, and an incrementing token.

    摘要: An embodiment of the invention comprises a virtual tape system supporting at least one Write Once Read Many (WORM) logical tape and at least one read-write logical tape, comprising a processor configured to a first task and/or a second task. The first task initializes a new logical data object from a single pool of at least two logical data objects, with the new logical data object bound with a member of a media type group consisting of a WORM data object or a read-write data object. The second task reuses one of the logical data objects without manual ejection and reinsertion. The reuse may include the processor configured to cycle the logical data object through a scratch pool as a selected scratch logical data object and mount the selected scratch logical data object with a write from beginning of tape command to bind at least one data attribute to the WORM data object.
