摘要： A remote copy system includes: a first storage system having a first logical volume accompanied with a first plurality of disk drives in the first storage system; a second storage system having a second logical volume, which is a virtual volume not accompanied with a second plurality of disk drives in the second storage system, the virtual volume configuring a first remote copy pair with the first logical volume; and a third storage system having a third logical volume accompanied with a third plurality of disk drives in the third storage system, the third logical volume configuring a second remote copy pair with the virtual volume and storing a copied data of data stored in the first logical volume. If the second storage system receives write data sent from the first storage system to the virtual volume, the second storage system transfers the write data to the third logical volume.

摘要： A first storage system stores information relating to the updating of data stored in that system as a journal. More specifically, the journal is composed of a copy of data that was used for updating and update information such as a write command used during updating. Furthermore, the second storage system acquires the journal via a communication line between the first storage system and the second storage system. The second storage system holds a duplicate of the data held by the first storage system and updates the data corresponding to the data of the first storage system in the data update order of the first storage system by using the journal.

摘要： A first storage subsystem includes a first storage device and a second storage device(s). A second storage subsystem includes a third storage device and a fourth storage device. A third storage subsystem comprises a fifth storage device and a sixth storage device. The first storage subsystem generates a dataset comprising an update number expressing the update order of the first storage device and write data stored in the first storage device, stores the generated dataset in the one or more second storage devices, and transmits the data set to the second and third storage subsystems. Each of the second and third storage subsystems stores the received dataset in the third storage device or fifth storage device, reads a dataset from the third or fifth storage device according to the update number, and stores the write data within the dataset in the fourth storage device or sixth storage device.

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.
摘要翻译：在由计算机采用的数据存储在存储系统中的系统中，存储系统将该数据传送到另一个存储系统，并且数据的副本被保存在另一个存储系统中。即使将数据写入计算机的存储系统，拷贝的一致性仍然保持，而不需要写入时间。源存储系统当写入时间被应用于写入请求时，记录写入时间并将该写入时间应用于所接收的写入数据，并且当不施加写入时间时，将记录的写入时间应用于所接收的写入数据，并且将写入数据以该写入时间传送到目标存储系统。目标存储系统根据写入时间将写入数据存储在目标存储系统中的逻辑卷中。

摘要： The data up to a point of time whereat failure has occurred will be restored at high speed at a remote site without imposing any burden on a host. The first storage system on the master side processes an I/O request from the host, and as a result of I/O processing to the second storage system on the remote side, transmits the update data. The second storage system retains data received from the first storage system as update log data. The host transmits a command for settling a state of an application to the first storage system as data, and the first storage system transmits the data to the second storage system. The host and the second storage system both retain an identifier corresponding to the command, and relate the identifier to the log data. Thereby, the host designates the identifier at any given time, whereby the second storage system restores the data at any given time.
摘要翻译：直到发生故障的时间点的数据将在远程站点高速恢复，而不会对主机造成任何负担。主机侧的第一存储系统处理来自主机的I / O请求，并且作为对远程侧的第二存储系统的I / O处理的结果，发送更新数据。第二存储系统将从第一存储系统接收的数据保留为更新日志数据。主机向第一存储系统发送用于确定应用状态的命令作为数据，并且第一存储系统将数据发送到第二存储系统。主机和第二存储系统都保留与该命令对应的标识符，并将该标识符与日志数据相关联。因此，主机在任何给定时间指定标识符，由此第二存储系统在任何给定时间恢复数据。

摘要： Even when a host does not give a write time to write data, consistency can be kept among data stored in secondary storage systems. The present system has plural primary storage systems each having a source volume and plural secondary storage systems each having a target volume. Once data is received from a host, each of the plural storage systems creates write-data management information having sequential numbers and reference information and sends, to one of the primary storage systems, the data, sequential number and reference information. Each of the secondary storage systems records reference information corresponding to the largest sequential number among serial sequential numbers and stores, in a target volume in an order of sequential numbers, data corresponding to reference information having a value smaller than the reference information based on the smallest value reference information among reference information recorded in each of the plural secondary storage systems.

摘要： In a configuration in which it is necessary to transfer data from a first storage system to a third storage system through a storage system between the storage systems, there is a problem that it is inevitable to give an excess logical volume to a second storage system between the storage systems. A remote copy system includes first storage system that sends and receives data to and from an information processing apparatus, a second storage system, and a third storage system. The second storage system virtually has a second storage area in which the data should be written and has a third storage area in which the data written in the second storage area and update information concerning the data are written. Data sent from the first storage system is not written in the second storage area but is written in the third storage area as data and update information. The data and the update information written in the third storage area are read out from the third storage system.
