    摘要: A remote file server managing a remote storage device and a local file server managing a local storage device are coupled to a communication network (e.g. the Internet). The local file server (A) replicates a file in the local storage device to the remote file server and, (B) if a first condition is satisfied, manages the replicated file which is the file from which the data is replicated as a migration target file. The local file server, even if the (B) is completed, does not delete the migration target file from the local storage device and, if the second condition is satisfied, deletes the migration target file from the local storage device.

    摘要: The present invention enhances user usability by storing more files close to the user. A replication processing part 3A creates a replica of a prescribed file, which is in a first file management apparatus, in a second file management apparatus. A single instance processing part 3B selects as a duplicate data removal target another prescribed file in the first file management apparatus in accordance with a first prescribed condition, and converts the selected other prescribed file to a reference-source file, which references data of a prescribed reference file. A stubification processing part 3C selects a stubification candidate file, which constitutes a target of a stubification process, in accordance with a second prescribed condition, and executes stubification processing with respect to the stubification candidate file in accordance with a third prescribed condition.

    摘要: A storage system comprises a second NAS storage apparatus and a third NAS storage apparatus for migrating an object managed by a first NAS storage apparatus. The second NAS storage apparatus comprises a processor and a storage medium, which is able to store data. The processor of the second NAS storage apparatus, with respect to an object for which a migration from the first NAS storage apparatus has started, stores path information of the object in the first NAS storage apparatus after including the path information in object management information, in the storage medium prior to migrating the object entity to the third NAS storage apparatus. Also, the processor, after receiving the object entity from the first NAS storage apparatus and migrating the object entity to the third NAS storage apparatus, stores the third NAS storage apparatus path information to the object entity in the object management information, and reflects the management information in the third NAS storage apparatus.
