    摘要: Snapshots are implemented by combining original data in a place where an operational volume has been updated with data in a place where the operational volume has not been updated. A snapshot management table maintains a value indicating that update has not been conducted, or a storage place of original data, for each of combinations of blocks in the operational volume and the snapshots. If there is a snapshot in which update has not been conducted in a update place at the time of update, then original data is copied and the snapshot management table is updated. The copied original data is managed by a difference block management table, which has a value indicating whether respective snapshots are referencing the data. If a snapshot is deleted, then the value indicating that the snapshot is referencing is altered in all entries in the difference block management table.

    摘要: A storage system including a snapshot volume arranged to provide each of a plurality of snapshot generations to the host as a virtual volume and to store data having an identical content in one storage area, and in that a management unit is arranged to: determine, when the host sends a request to create the original volume as a new volume of a designated generation, whether the designated generation is a generation of the copy volume or not; overwrite data in the copy volume for a block address of the designated generation indicating the snapshot volume if the generation of the copy volume is different from the designated generation; and change mapping information of the copy volume to the mapping information of the original volume.

    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: In the storage-based snapshot creation, a block-selection specifying unit provided on a NAS processing unit specifies a block, which becomes necessary for the generation of snapshot data, to a specified-block analyzing unit within a disk apparatus. Moreover, a disk controller generates the snapshot data on the block specified as the snapshot target, while making an inquiry to the specified-block analyzing unit. This makes it possible to create the snapshot in a storage-capacity reduced manner, and to specify the snapshot creation in a partition, file, or directory unit.

    摘要: A file server has plural NAS nodes having three processors dispersed in function, a shared cache memory shared between the plural NAS nodes and backed up by a battery, and plural storage devices. A log area for storing data with respect to an access request received by each NAS node is arranged in the shared cache memory. A network processor stores the data with respect to the access request to the log area, and transfers the data of the memory by a DMA at a reading time. Even when a failure is happened in a certain NAS node, another NAS node restores a file system using the log and continues processing to store the data with respect to the access request to the shared cache memory.

    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.
