More Information
Summary:To provide an information processing device, information processing method, and information processing program, which appropriately secure time between completion of data migration to a data migration destination magnetic tape and the time the magnetic tape is selected as a transfer source magnetic tape.SOLUTION: An information processing device provided herein provides control to select a data migration destination magnetic tape from among one or more magnetic tapes on the basis of an indicator value computed for each magnetic tape and designed to correlate with the amount of invalid data in a data group recorded on each of the one or more magnetic tapes and migrate data recorded on a data migration source magnetic tape to the selected migration destination magnetic tape.SELECTED DRAWING: Figure 7 【課題】データの移行先の磁気テープへデータを移行した後に、その磁気テープがデータの移行元の磁気テープとして選択されるまでの時間を適切に確保することができる情報処理装置、情報処理方法、及び情報処理プログラムを得る。【解決手段】情報処理装置は、磁気テープ毎に算出される指標値であって、一本以上の磁気テープそれぞれに記録されたデータ群のうちの無効データの量に相関する指標値に基づいて、一本以上の磁気テープの中からデータの移行先の磁気テープを選択し、データの移行元の磁気テープに記録されたデータを、選択した移行先の磁気テープに移行する制御を行う。【選択図】図７
