PROBLEM TO BE SOLVED: To provide a storage control apparatus and a storage control method wherein in a system having a plurality of disk devices and equipped with secondary disk devices at remote sites, the data transfer amount between a central processing unit and disk devices can be reduced when duplicate disk write is performed, the performance can be prevented from being degraded even if the distance between control units is elongated, and the intermediate results of a transaction are not left. SOLUTION: A standard time is determined and a program is provided which instructs a secondary central processing unit to reflect only update information having a write time older than the standard time, upon a logical disk included in the secondary disk device. An update information reflection part is provided for reflecting only update information having a write time older than the standard time designated to the secondary disc device by the secondary central processing unit, upon the logical disk included in the secondary disk device, by receiving the instruction from the secondary central processing unit.
