    • 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.
    • 本发明能够创建存储在不同卷或不同存储系统中的父文件的克隆文件,并且使得能够在卷和存储系统之间迁移父文件和克隆文件。 文件存储器执行控制以创建具有能够在存储系统和卷之间唯一地标识父文件的标识符的虚拟父文件,并使用所述标识符获取父文件的块布局信息。 文件存储在创建克隆文件的卷中创建虚拟父文件,并将该文件设置为克隆文件的虚拟父文件,以便能够创建存在于不同的父文件中的父文件的克隆文件 卷或不同的存储系统。 此外,通过组合创建虚拟父文件并切换虚拟父文件指向的父文件的标识符,启用跨越存储系统和卷的克隆文件和父文件的迁移。

    • 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.
    • 文件服务器耦合到多个用户终端和远程文件服务器。 文件服务器在存储装置中存储从多个用户终端接收到的文件的数据,将文件复制到远程文件服务器,存储存储在存储装置中的文件,并且在接收到来自用户的访问请求时 终端,从存储装置读出文件的数据,并且如果与访问请求相关的文件没有被保留,则将数据发送到用户终端,并且从远程文件服务器回收该文件的数据并发送该文件的数据 如果与访问请求相关的文件被扼杀,则发送给用户终端。 文件服务器在远程文件服务器中将优先于另一用户的特定时间内执行会话断开请求的用户的数据复制到文件服务器。

    • 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.
    • 提供了一种包括服务器和第一和第二存储系统的计算机系统。 第一存储系统存储重复数据的数据共享至少一部分数据与其他数据,由多个重复数据删除的数据共享的共享数据,以及表示存储的数据的类型的第一类型数据,包括重复数据删除数据和共享数据 。 重复数据删除的数据通过指向共享数据的指针与共享数据相关联,并且包括指示与共享数据的差异的差分数据。 服务器从第一类型数据创建表示存储在第二存储系统中的数据类型的第二类型数据。 第二存储系统在顺序读取之前读取排除重复数据的位置之前的读取位置存储与重复数据删除数据相关联的共享数据,并存储第二类型数据。
