摘要： The file synchronization processing among sites which can reduce the response time is realized. By the CAS device creating a list of at least a part of the file groups which the first sub-computer system archived or backed up to the data center as an update list and transferring the update list to the second sub-computer system, the second sub-computer system determines whether the file is valid or not by using the update list (See Fig. 2).
摘要翻译：实现可以减少响应时间的站点之间的文件同步处理。通过CAS设备，创建将第一子计算机系统归档或备份到数据中心的至少一部分文件组的列表作为更新列表，并将更新列表传送到第二子计算机系统，第二个子计算机系统通过使用更新列表来确定文件是否有效（见图2）。

摘要： In file de-duplication using hash value comparison, hash values of all target files must be calculated and actual data of all files must be read for hash value calculation, so that the processing time was long. The present invention provides a file storage system comprising a controller and a volume storing a plurality of files, the volume including a first directory storing a first file and a second file and a second directory storing a third file being created, wherein the controller migrates actual data of the second file to the third file, sets up a management information of the second file so that the third file is referred to when the second file is read, and if the sizes of actual data of the first file and the actual data of the third file are identical and the binaries of the actual data of the first file and the actual data of the third file are identical, sets up a management information of the first file to refer to the third file when reading the first file.
摘要翻译：在使用散列值比较的文件重复数据删除中，必须计算所有目标文件的散列值，并且必须读取所有文件的实际数据以进行哈希值计算，以便处理时间长。本发明提供了一种包括控制器和存储多个文件的卷的文件存储系统，所述卷包括存储第一文件和第二文件的第一目录和存储正在创建的第三文件的第二目录，其中所述控制器迁移实际将第二文件的数据提供给第三文件，建立第二文件的管理信息，以便在读取第二文件时参考第三文件，并且如果第一文件的实际数据的大小和实际数据的大小第三文件是相同的，并且第一文件的实际数据和第三文件的实际数据的二进制文件是相同的，当读取第一文件时，设置第一文件的管理信息以引用第三文件。

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.
摘要翻译：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。

摘要： An ACL, a setting table, and backup data are used to create an inter-base data sharing file system at a base permitted to share data. This enables data to be shared by bases. In a process for restoring backup data, with reference to the ACL and the setting table, a data management computer system determines whether or not each restore destination base is permitted to share data, and executes a restore process only on restore destination bases permitted to share data. (See fig. 3)
摘要翻译： ACL，设置表和备份数据用于在允许共享数据的基础上创建基站间数据共享文件系统。这使得数据可以由基础共享。在恢复备份数据的过程中，参考ACL和设置表，数据管理计算机系统确定每个恢复目的地基站是否被允许共享数据，并且仅在允许共享的恢复目的地基础上执行恢复过程数据。（见图3）
