摘要： To provide a storage system and a file management device which enable obtaining a file, without designating detailed information. A client is provided with a read request module that sends a file read request containing information corresponding to a file name and an archived date of the file. A WORM archive server is provided with a file identifying module that extracts information corresponding to the file archived date and the file name from the file read request that was received from the client, and identifies the latest archived file with the file name registered before the archived date corresponding to the extracted information from among files recorded in a storage device, and a file sending module that sends the identified data to the client that sent the request.

摘要： A file system access control which carries WORM commitment for files in a single transaction is provided. The file system access control apparatus includes command files that support WORM commitment, interprets WORM commitment command which is registered in command files by means of a daemon process module and executes WORM commitment in a file. A plurality of files and those under management of directories are changed of the file access modes to meet WORM. In addition, a system that allows WRITE command for the command files by means of a standard interface of the file system. The results of WORM commitment is registered in the repository files under the system regarding the present invention.

摘要： When CPU 11 receives a request to write to a file stored in a storage device 10 from client computers 30 through 32, it references the object control table of the subject file, and confirms the WORM attribute of the subject file. The CPU 11 references the WORM range control table, and determines whether or not the write subject range is set to a WORM range. When the write subject range is not set to a WORM range, the CPU 11 executes write to the subject file. When WORM form is set for write data, the CPU 11 updates the WORM range control table and sets WORM form for the written data.

摘要翻译： 当CPU 11从​​客户端计算机30到32接收到对存储在存储装置10中的文件的写入请求时，引用该对象文件的对象控制表，并确认该对象文件的WORM属性。 CPU 11参考WORM范围控制表，并确定写入对象范围是否被设置为WORM范围。 当写入对象范围未设置为WORM范围时，CPU 11执行对主题文件的写入。 当WORM表单设置为写入数据时，CPU 11更新WORM范围控制表，并为写入的数据设置WORM表单。

摘要： The client computer which transmits an access request specifying an object existing in the first file system and the second computer which accesses the second file system are connected to the first computer which accesses the first file system. The second file system includes a shared directory. A specific object which is an object complying with the path name including the name determined in accordance with the type of the second computer is stored in the shared directory. The controller mounts the shared directory to the first file system. The controller creates a link which comprises a name determined in accordance with a certain naming regulation independent of the type of the computer and corresponds to the specific object in the first file system.

摘要： A data intermediate server 300 comprises the functions of reading data stored in storage servers ST1 through ST3 and sending the data to a media server 600 according to backup commands received from a backup control device 400 over a local area network LAN4. The data intermediate server 300 and the storage servers ST1 through ST3 are connected by channels that do not permit Internet protocol traffic but only data targeted for backup and control data assigned thereto. As a result, client data stored on the storage servers can be properly backed up while preventing data from being improperly retrieved or leaked.

摘要翻译： 数据中间服务器300包括读取存储在存储服务器ST1至ST3中的数据的功能，并且根据从备用控制设备400通过局域网LAN4接收的备份命令将数据发送到媒体服务器600。 数据中间服务器300和存储服务器ST1至ST3通过不允许因特网协议流量的信道连接，而仅通过分配给备份和控制数据的数据进行连接。 因此，可以正确地备份存储在存储服务器上的客户端数据，同时防止数据被不正确地检索或泄漏。
