摘要： A virtual tape device being located between a host and a tape library and storing data as a virtual logical volume in a storage, has a calculator that calculates a time period in which a robot moves, from a cell to a drive device, the physical tape in accordance with an instruction when the instruction is issued to recall the target logical volume redundantly stored on the physical tapes stored in two or more cells included in different tape libraries or in the same tape library and to store the target logical volume, a calculator that calculates a time period for tape positioning, and a unit that calculates a time period on the basis of the time period in which the robot moves from the cell to the drive device and the time period for the tape positioning, and that selects a physical tape corresponding to the shortest time period.
