COPYING DEVICE, COPYING METHOD, COPYING PROGRAM, BLOCK IDENTIFICATION INFORMATION ACQUISITION PROGRAM, AND RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To reduce a time required for copying of a storage device by specifying a block that is not a copying target and not performing the copying when copying data recorded in the storage device in block units. SOLUTION: This copying device copies the data recorded in the storage device that is a copying source to a storage device that is a copying destination in the block units. The copying device has: an out-of-target block identification information acquisition part for acquiring out-of-target block identification information for identifying a block recording contents of an out-of-target file that is not the copying target among files recorded in the storage device that is the copying source; and a target block copying part for copying each of a plurality of blocks of the storage device that is the copying source to the storage device that is the copying destination under the condition that block identification information about the block does not coincide with the out-of-target block identification information.
