摘要： During the normal operation state of a computer system 1000, the data stored in a primary storage system 200P is copied to an intermediate storage system 200I via synchronous copying and the data stored in the intermediate storage system 200I is copied to a secondary storage system 200R via asynchronous copying. During the reverse operation state, however, the data stored in the secondary storage system 200R is copied to the intermediate storage system 200I via asynchronous copying and the data stored in the intermediate storage system 200I is copied to the primary storage system 200P via synchronous copying.In this way, practical remote copying can be carried out in a computer system in which three or more storage devices are installed at different locations and connected serially.

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： To provide a computer system constituting a multitarget array and utilizing a remote copy technique for backing up data, in which when a failure occurs in a primary site, a new pair is formed between remaining two secondary sites without copying all data. A first secondary site is associated with the primary site by synchronous remote copy. A second secondary site is associated with the primary site by asynchronous remote copy. A storage system of the first secondary site includes a difference bitmap indicating an area to which data has been written from a host computer. When a failure occurs in a host computer of the primary site, only data of an area indicated by the difference bitmap is transferred to a storage system of the second secondary site.

摘要： In the conventional storage system, consistency is ensured only for writing from a single storage. Asynchronous remote copying and local replication are also alternately suspended in the conventional system, so that the suspension time increases and the volume in which consistency is obtained becomes old. Two local replicas are prepared, for a volume containing stored data that is transferred from the main site by asynchronous remote copying, in the storage at the sub-site. Each pair of local replicas is alternately suspended by a time-specific suspension command according to the time of the timestamp attached to the write data, and replica data in which the time sequence is secured is continually prepared. When a failure occurs at the main site, the data is recovered using the replica data.
摘要翻译：在传统的存储系统中，只能从单个存储器写入一致性。异常远程复制和本地复制也在传统系统中交替挂起，使得暂停时间增加，并且获得一致性的容量变得较旧。对于包含从主站点通过异步远程复制传输的存储数据的卷，在子站点的存储中准备了两个本地副本。根据附加到写入数据的时间戳的时间，通过时间特定的暂停命令交替地暂停每对本地副本，并且连续地准备其中确保时间序列的副本数据。当主站发生故障时，使用副本数据恢复数据。
