Abstract

A storage management device generates property data for management of a storage file from a storage target file upon request of storage of the storage target file from an external device, and uses the generated property data and existing property data to determine whether a file having the same contents as the storage target file is stored or not in a primary storage. When it is determined that the file having the same contents is stored in the primary storage, the storage management device avoids storage of the storage target file, thereby preventing wasted use of the primary storage resources.
