摘要： A file server is replaced efficiently. A computer system includes a first file server, a second file server, and a third file server. The first file server retains file data storage information which indicates, for each file, whether data of the relevant file is stored in a first storage device or not; and after a data input/output request from a client terminal is switched from the first file server to the third file server, the third file server selects either the first file server or the second file server as a data transfer request destination of a target file of the data input/output request from the client terminal, based on the file data storage information sent from the first file server.

摘要： A file server is coupled to a plurality of user terminals and a remote file server. The file server, stores, in a storage device, data of files received from the plurality of user terminals, replicates the files to the remote file server, stubs the files stored in the storage device, and, upon receiving an access request from the user terminal, reads out data of the file from the storage device and transmits the data to the user terminal if a file related to the access request is not stubbed, and, recall data of the file from the remote file server and transmits data of the file to the user terminal if a file related to the access request is stubbed. The file server replicates, to the remote file server, data of a user who performs a session disconnection request to the file server within a certain time in preference to another user.

摘要： It is provided a computer system, comprising a server and first and second storage systems. The first storage system stores deduplicated data sharing at least a part of data with other data, shared data shared by a plurality of pieces of the deduplicated data, and first type data representing a type of the stored data including the deduplicated data and the shared data. The deduplicated data is associated with the shared data by a pointer to the shared data, and includes differential data indicating a difference from the shared data. The server creates second type data representing a type of the data stored in the second storage system from the first type data. The second storage system stores the shared data associated with the deduplicate data at a reading position before a position at which the deduplicated data is read in sequential reading and stores the second type data.

摘要： The present invention enables creation of a clone file of a parent file stored in a different volume or a different storage system, and enables migration of a parent file and a clone file among volumes and storage systems. A file storage performs control to create a virtual parent file having an identifier capable of uniquely identifying a parent file among storage systems and volumes, and to acquire block layout information of the parent file using said identifier. The file storage creates a virtual parent file in the volume in which the clone file is created, and sets the file as a virtual parent file of the clone file so as to enable creation of a clone file of a parent file that exists in a different volume or a different storage system. Moreover, by combining creating the virtual parent file and switching the identifier of the parent file which is pointed by the virtual parent file, migration of clone files and parent files astride storage systems and volumes is enabled.

摘要： The prior art information system could not migrate a file in a file sharing system provided by a file storage to a plurality of cloud storages having different forms of connection and different properties, and therefore, could not manage the files via a single Stub information. The present invention provides a data mover program in a file storage to select one or more migration destination cloud storages based on a migration policy, a connection information table of cloud storages and a property information table of cloud storages. Then, a Stub information of the migrated file is created, and an identification information of the file in the cloud storage is stored in a file information table. When access occurs from a client to a file storage, the data mover program downloads a file from the cloud storage stored in the file information table corresponding to the Stub information and provides the file to the client.
摘要翻译：现有技术的信息系统不能将由文件存储器提供的文件共享系统中的文件迁移到具有不同形式的连接和不同属性的多个云存储器，因此无法通过单个存根信息来管理文件。本发明提供一种文件存储器中的数据移动器程序，用于基于迁移策略选择一个或多个迁移目的地云存储，云存储的连接信息表和云存储的属性信息表。然后，创建迁移文件的存根信息，将云存储中的文件的识别信息存储在文件信息表中。当从客户端到文件存储进行访问时，数据移动器程序从与存根信息相对应的文件信息表中存储的云存储中下载文件，并将该文件提供给客户端。

摘要： A file management sub-system executes file migration without causing an unintended drop in the response time or the like. When a management computer issues a file migration direction, a file storage apparatus notifies client computer associated with a migration target file that file migration is scheduled. When postponement or suspension of file migration is requested by the client computer, the file migration is postponed or suspended.

摘要： A file server is coupled to a plurality of user terminals and a remote file server. The file server, stores, in a storage device, data of files received from the plurality of user terminals, replicates the files to the remote file server, stubs the files stored in storage, and, upon receiving an access request from the user terminal, reads out data of the file from storage and transmits the data to the user terminal if a file related to the access request is not stubbed. If a file related to the access request is stubbed, the file server recalls data of the file from the remote file server and transmits data of the file to the user terminal. The file server replicates, to the remote file server, data of a user who performs a session disconnection request to the file server within a certain time in preference to another user.
