A storage system comprises a primary storage system comprising a primary storage apparatus and a primary control apparatus for controlling the primary storage apparatus; and a secondary storage system comprising a secondary storage apparatus and secondary control apparatus for controlling the secondary storage apparatus. The primary storage apparatus and the secondary storage apparatus are connected to each other via a communication line. The primary storage system sends, to the primary storage apparatus, a data-transfer instruction instructing the primary storage apparatus to transfer predetermined data stored in the primary storage apparatus to the secondary storage system. The primary storage apparatus receives the data-transfer instruction, reads out the predetermined data from the primary storage apparatus, and sends the data via the communication line to the secondary storage apparatus of the secondary storage system. |
