Abstract
A method and system for improving tape drive memory storage is provided. The method includes receiving, by a storage tape drive hardware device, a data stream. Duplicate data chunks of the data stream are identified and deleted such that a group of data chunks remain in a non-volatile memory device (NVS) of the storage tape drive. The group of data chunks is written to a data storage tape cartridge. Pointers are generated and stored within the data storage tape cartridge. The pointers are associated with a location within an NVSfor storing de-duplication hashes identifying each data chunk of the group of data chunks stored within data storage tape cartridge. The de-duplication hashes are written from the NVSto a manager non-volatile memory device (MNVS) of a storage tape drive hardware library system. The MNVS is updated.
