Abstract: An exemplary storage system of the invention processes requests to access a primary volume and a plurality of secondary volumes forming pairs with the primary volume. In each of the plurality of secondary volumes, address areas are defined which are respectively associated with address areas of the primary volume. Each of the plurality of secondary volumes stores differential data with respect to data in the primary volume. A controller monitors write accesses to the primary volume and the plurality of secondary volumes, and retains a monitoring result. The controller controls, based on, in the monitoring result, presence/absence of past write accesses to a plurality of areas in the primary volume and areas respectively corresponding to the plurality of areas in the plurality of secondary volumes, accesses to the primary volume.

Abstract: If an I/O load on a first virtual storage area falls below a first threshold, a controller copies data in a first storage area, which is allocated to the first virtual storage area, to a third storage area in a second tier storage area, and allocates the third storage area instead of the first storage area to the first virtual storage area. If an I/O load on a second virtual storage area exceeds a second threshold which is greater than said first threshold, the controller copies data in a second storage area, which is allocated to the second virtual storage area, to a fourth storage area in a first tier storage area, and allocates the fourth storage area instead of the second storage area to the second virtual storage area.

Abstract: An image forming machine transitions into a sleep mode at a preset time of day, and keeps the sleep mode for a prescribed interval. The image forming machine includes an I/O interface, a printer, a memory, and a controller. The interface inputs a print job. The printer executes a printing of the print job. The memory stores therein an entirety or part of the print job overlapping the interval of the sleep mode, as a hold job.
