A storage apparatus includes: an associating unit that associates a first memory area in which data to be copied are stored and a second memory area of a destination storage apparatus to which the data are copied; a detecting unit that detects a start or an end of copying the data from the first memory area to the second memory area associated by the associating unit; and an access control unit that controls access to the first memory area and the second memory area based on a result of detection performed by the detecting unit.
