The present invention enables a unified way of accessing files generated by application programs configured to store contents in files in different formats, without using a conversion program. A database for holding correspondence between an identifier of a content and a storage position of the content is generated based on a backup catalog generated by a backup server, and contents are accessed by using this database. Contents generated by a plurality of different application programs are accessed in a unified way using a single name space. |
