摘要： A computer system comprising storage devices having different characteristics, a client computer, and a file access controller managing the storage devices with the HSM is disclosed. The file access controller provides a normal directory tree and a virtual directory tree, according to the configuration, and provides a first file stored in a first storage device through the normal directory tree and the virtual directory tree. And, the file access controller switches providing of a second file stored in a second storage device, depending on a used directory tree, which is used by the at least one client computer, and which is the normal directory tree or the virtual directory tree. Examples of the switch are about accessibility of the second file and recall processing of the second file.

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。

摘要： Provided is a computer system in which a plurality of virtual machines operate on a host computer. The host computer has a time subtraction table for storing the time subtraction with the respective virtual machines, and a log collection unit for collecting the logs of the respective virtual machines. The log contains a time stamp which shows at least the log output time. The log collection unit corrects the time stamp of the logs collected from the respective virtual machines based on the time subtraction stored in the time subtraction table. According to this computer system, the logs of the virtual machines operating in a time series that is different from the time series of the host computer can be collected upon integrating the time series of the virtual machines and the host computer.

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.
