摘要： Provided are a backup system and a backup method for backing up data written by a host into a logical volume provided by a storage system, wherein an update location in the logical volume updated by the host is managed, and the storage system is controlled to selectively back up the data written into the update location in the logical volume based on the management result of the update location. It is thereby possible to ensure a fast data read speed in the backup of raw volumes and an easy multiplatform backup, whereby a backup system and a backup method capable of performing backup efficiently are realized.

摘要： A storage system of this invention maintains consistency of the stored contents between volumes even when a plurality of remote copying operations are executed asynchronously. A plurality of primary storage control devices and a plurality of secondary storage control devices are connected by a plurality of paths, and remote copying is performed asynchronously between respective first volumes and second volumes. Write data transferred from the primary storage control device to the secondary storage control device is held in a write data storage portion. Update order information, including write times and sequential numbers, is managed by update order information management portions. An update control portion collects update order information from each update order information management portion, determines the time at which update of each second volume is possible, and notifies each-update portion. By this means, the stored contents of each second volume can be updated up to the time at which update is possible.

摘要： In a system in which data employed by a computer is stored in a storage system, the storage system transfers this data to another storage system and a copy of the data is maintained in the other storage system, consistency of the copy is maintained even in the case of data written to the storage system by a computer, to which a write time is not applied.A source storage system, when a write time is applied to a write request, records the write time and applies this write time to the received write data and, when no write time is applied, applies the recorded write time to the received write data and transfers the write data with this write time applied thereto, to another storage system. The target storage system stores the write data in a logical volume in the target storage system in accordance with the write time.

摘要： In a system in which data employed by a computer is stored in a storage system, the storage system transfers this data to another storage system and a copy of the data is maintained in the other storage system. The consistency of the copy is maintained even when data is written, to the storage system by a computer, without having a write time applied. A source storage system, when a write time is applied to a write request, records the write time and applies this write time to the received write data and, when no write time is applied, applies the recorded write time to the received write data and transfers the write data with this write time applied thereto, to a target storage system. The target storage system stores the write data in a logical volume in the target storage system in accordance with the write time.

摘要： A storage system includes a plurality of storage apparatuses respectively connected to a host apparatus via a network. A disk controller of each storage apparatus has DKC identifying information for recognizing itself, a logical device identifier created based thereon, and a virtual/logical device identifier set containing a real/logical device identifier and a virtual/logical device identifier. The storage apparatus defined with a pair relationship creates a virtual/logical device identifier set of a mirrored image relationship by replacing its own real/logical device identifier and using it as its own virtual/logical device identifier.

摘要： The storage system of the present invention has a simple configuration and ensures redundancy of the system. The primary storage control device and the first secondary storage control device are connected by a synchronous read method, and the primary storage control device and the second secondary storage control device are connected by an asynchronous read method. The primary storage control device sets a management number in the update data and saves a journal data. The primary storage control device associates the management number with the update data and transmits them to the first secondary storage control device. The first secondary storage control device writes the update data to the first secondary volume, associates the management number with the storage destination address of the update data and stores them in the maintenance table. If the primary storage control device stops, the first secondary storage control device becomes anew a primary storage control device. The first secondary storage control device is connected to the second secondary storage control device by an asynchronous read method.
