  • Patent number: 11372575
    Abstract: Providing copy data candidates appropriate for a user request. Included are an operational portal that registers user request information; a data catalog that manages information about multiple copy data located at sites configuring a hybrid cloud system; a data allocation service that allocates duplicated copy data to the sites; and a guideline management service that selects a copy data candidate appropriate for user request information. The guideline management service acquires information about copy data containing the same data as user request information from the data catalog and verifies whether there is a copy data candidate satisfying the user request information. When there is consequently no copy data candidate satisfying the user request information, the copy data is allocated to the site on condition that the copy data is optimal enough to satisfy a generation schedule and a processing speed of a copy data candidate satisfying the user request information.
