Abstract: A storage system 103 carries out first and second de-duplication processes in response to receiving a write request from a client. First, a determination is made as to whether a write target data item overlaps with any of the stored data items of a part of a stored data item group, which is a user data item group stored in a storage device 209, and if so, the write target data item is prevented from being stored in the storage device. Second, a determination is made as to whether a target stored data item, which is not finished being evaluated as to whether it overlaps with the stored data item in the first de-duplication process, overlaps with another stored data item, and if so, the target stored data item or the same data item overlapping with the target stored data item is deleted from the storage device 209.

Abstract: Provided are a content transfer system, a content transfer method, and a home server capable of backing up all backup target contents without having to transfer all backup target contents. This content transfer system includes a home storage and an online storage. The home storage transfers identifying information of a backup target content to the online storage and requests the online storage to determine the existence of a content that is identical to the backup target content upon requesting the online storage to back up the backup target content, transfers metadata to the online storage when an identical content exists in the online storage, and transfers the backup target content to the online storage in all other cases.

Abstract: Provided is a storage center including a storage subsystem for storing content data to be used by the user's home server, and a center server for controlling the storage subsystem. The center server aggregates the content recording reservation requests sent from several home servers, obtains content data from a content server and stores the content data in the storage subsystem at a designated recording start time, and notifies the user's home server that the recording reservation is complete.

Abstract: An aspect of the invention is a multi-client storage system comprising a management computer including a processor and a memory, for allocating resources of a plurality of storage apparatus to a plurality of clients, the management computer comprising: a receiving unit for receiving conditions for a client to which a new resource is to be allocated; a determining unit for determining whether the new resource is securable under the received conditions without changing resources allocated to existing clients and conditions for the volumes for each of the existing clients; and an allocation unit for securing, when it is determined that the new resource is securable under the received conditions, the new resource under the received conditions for the client in the plurality of storage apparatus and allocating the new resource to the client.

Abstract: A NAS device providing a snapshot function for executing CoW processing in multiple successive block units is provided, wherein upon restoring a file saved in a file system sharing from a snapshot, the speed for restoring files is enhanced by restoring only data blocks that have been changed within the data blocks constituting a file, to thereby reduce the amount of data being restored and cut down CoW processing. Upon restoring a file stored in file system sharing from a snapshot file, data blocks storing different data between the restore source file and the restore destination file are specified based on a differential map table and a differential block table, and only the specified data blocks are restored. Further, upon restoring data from a file other than the snapshot, the data blocks constituting the restore source file and the restore destination file are compared, and only the data blocks storing different data are restored.

Abstract: The present invention comprises a management computer which exchanges information with storage apparatuses and host computers of primary sites and a secondary site via a management network and which manages a data processing performance and a data processing status of each of the sites, wherein, when any of the primary sites is subject to disaster, the management computer selects a normal primary site for which a data transfer time of a restoration target application is within a recovery time objective as a restoration site which possesses processing performance for restoring the application, and remote-copies restoration copy data, which exists at the secondary site, to the storage apparatus of the primary site selected as the restoration site, via a data network.

Abstract: The present invention relates to a migration of a file from a path denotative NAS server to an ID denotative NAS server. In a file management device a migration-use path denotative NAS access section obtains a file deposit location from the path denotative NAS server, selects a migration target file based on the deposit location, and sends a read request with the deposit location of the migration target file to the path denotative NAS server, so as to obtain the migration target file. A migration-use denotative NAS access section generates a write request with the migration target file, sends it to the ID denotative NAS servers, and writes the file therein. In addition, the migration-use ID denotative NAS access section registers a GUID received from the ID denotative NAS servers in a file name/GUID management table, together with the file name of the migration target file.
