A storage control device includes a processor which performs first copy of copying first data stored in a first storage device into a first backup region upon detecting a failure presage in the first storage device. The processor performs first write of writing second data specified in a first write request to the first storage device and second write of writing the second data into the first backup region upon receiving the first write request while performing the first copy. The processor performs second copy of copying third data stored in the first backup region to a second storage device upon completing the first copy. The processor performs third write of writing fourth data specified in a second write request to the second storage device in place of the first storage device upon receiving the second write request after completion of the second copy.
