Abstract
In a storage system, a processor divides a plurality of sections that constitute a physical storage area in a storage device into primary sections and secondary sections, associates one primary section and one secondary section with each other and then manages the associated primary section and secondary section, and writes data having been written to a primary section also to a secondary section corresponding to the primary section.
