Abstract

A storage management apparatus includes an acquiring unit and a control unit. When a first storage apparatus is active and a second storage apparatus is on standby and backup data corresponding to a plurality of data stored in the first storage apparatus are stored in the second storage apparatus, the acquiring unit acquires frequency information from the first storage apparatus, which shows frequency of access from a host apparatus to individual data in the plurality of data. Based on the frequency information, the control unit executes a deciding process that decides in which out of a plurality of storage regions with different access performance provided by the second storage apparatus respective data in the backup data are to be placed, and transmits instruction information to the second storage apparatus, which has the respective backup data placed in the storage regions decided by the deciding process.
