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： A control unit of a storage system controller receives an access command to a first file specifying a first access position in the first file. A storage apparatus stores management information of the first file and management information of each of subfiles obtained by dividing the first file. The management information of the first file contains information associating a data position in the first file and management information of a subfile containning data at the data position. The management information of each of the subfiles contains information associating a data position in the corresponding subfile and a physical storage position. The control unit references the management information of the first file to identify the management information of the subfile containning the data at the first access position, and references the management information of the identified subfile to identify a physical storage position of the first access position.

摘要： Provided is a technique capable of efficiently operating files and directories that are stored in storage located in a physically far place from a file server, without causing a network latency. An index creation program is also loaded in a cloud computing environment, and a flag, which indicates whether or not to execute batch processing to a directory that has been migrated to the cloud side, is provided, whereby it becomes possible to collectively execute index creation processing for the migrated directory on the cloud side. More specifically, upon completion of migration of all files under a given directory to the cloud side, a flag, which indicates whether or not to perform batch processing on the cloud side, is validated for the metadata of the directory. Such a batch processing flag can be held for each application such as applications of the index creation processing and the virus check processing.
摘要翻译：提供了一种技术，其能够有效地操作存储在位于物理上远离文件服务器的存储器中的文件和目录，而不会造成网络延迟。索引创建程序也被加载到云计算环境中，并且指示是否对已经迁移到云端的目录执行批处理的标志，从而可以共同地执行索引创建处理云端迁移的目录。更具体地说，在将给定目录下的所有文件迁移到云端之前，指示是否对云端执行批量处理的标志被验证为目录的元数据。可以针对诸如索引创建处理和病毒检查处理的应用的每个应用来保持这样的批处理标志。

摘要： When a deletion request to delete a file system is made and a retention period of the file system to be deleted has not expired, the retention period end date and time is displayed at high speed. A CPU 11 gives a retention period attribute to each file of a file system 16 and manages the furthest future retention period end date and time, from among the retention periods of the files, as a retention period end date and time of the file system. If a deletion request to delete the file system 16 is made and the retention period end date and time of the file system 16 is future time ahead of the current time when the deletion request is made, processing for deleting the file system 16 is stopped and the retention period end date and time of the file system 16 is displayed on a screen 235.
摘要翻译：当删除文件系统的删除请求并且要删除的文件系统的保留期间未到期时，保持期结束日期和时间以高速显示。 CPU11给予文件系统16的每个文件的保留期限属性，并且从文件的保留期间作为文件系统的保留期限结束日期和时间管理最远的未来保留期结束日期和时间。如果进行删除文件系统16的删除请求，并且文件系统16的保留期限结束日期和时间是在作出删除请求的当前时间之前的未来时间，则删除文件系统16的处理被停止，并且文件系统16的保留期限结束日期和时间被显示在屏幕235上。
