Abstract:
Software for reclaiming a storage medium. The software determines that a first storage medium storing data in a linear tape file system (LTFS) format meets a predetermined condition indicating that the first storage medium should be reclaimed. Responsive to reading requested data from the first storage medium, and responsive to determining that the first storage medium meets the predetermined condition, the software writes the requested data to a second storage medium in the LTFS format. Subsequent to writing the requested data to the second storage medium, the software reconciles the first storage medium to delete expired data. Subsequent to reconciling the first storage medium, the software explicitly reclaims remaining data on the first storage medium to the second storage medium in the LTFS format.

Claim (Index 15):
A computer system for reclaiming a storage medium, the computer system comprising:\n a processor(s) set; and a computer readable storage medium; wherein: the processor set is structured, located, connected and/or programmed to run program instructions stored on the computer readable storage medium; and the program instructions include:\n program instructions to determine that a first storage medium storing data in a linear tape file system (LTFS) format meets a predetermined condition indicating that the first storage medium should be reclaimed, wherein the predetermined condition is a policy based, at least in part, on a generation of the first storage medium and on a utilization of the first storage medium, and wherein the predetermined condition is met when the generation of the first storage medium is older than a first predetermined threshold and when a percentage of valid capacity for valid files to a total tape capacity of the first storage medium is below a second predetermined threshold; \n program instructions to, responsive to reading requested data from the first storage medium, and responsive to determining that the first storage medium meets the predetermined condition, write the requested data to a second storage medium in the LTFS format, wherein the second storage medium is selected based, at least in part, on a generation of the second storage medium, wherein the generation of the second storage medium is newer than the generation of the first storage medium; \n program instructions to, subsequent to writing the requested data to the second storage medium, reconcile the first storage medium to delete expired data; and \n program instructions to, subsequent to reconciling the first storage medium, explicitly reclaim remaining data on the first storage medium to the second storage medium in the LTFS format, wherein a time required for explicitly reclaiming is reduced due to the requested data having already been written to the second storage medium, and due to the deleted expired data not having to be written to the second storage medium.
