Abstract:
A consumption value of each storage medium and an upper limit related to writing are managed. Respective consumption value and the upper limit of each of two or more storage media out of a plurality of storage media constituting a storage media group are specified, and a remaining use period value is computed for each of the storage media using the upper limit and the consumption value. Based on each of the computed remaining use period values, data in at least one storage medium out of a plurality of storage media belonging to the selected storage area group is shifted to a storage medium which is different form the storage area group.
