Abstract
A processor generates a parity from dummy data attached to a first piece of data of a plurality of pieces of data and a piece of data other than the first piece of data when writing the plurality of pieces of data into a first storage apparatus. Then, the processor stores the parity in a second storage apparatus. The processor performs a reading-out process in parallel with a restoration process when reading out the plurality of pieces of data from the first storage apparatus and writing them into the second storage apparatus. The reading-out process is a process to read out the first piece of data from the first storage apparatus and to write it into the second storage apparatus, and the restoration process is a process to restore a second piece of data among the plurality of pieces of data by using the dummy data and the parity.
