    • Provided is a remote copy system capable of guaranteeing the time ordering of data to be handled by a remote site even when the tasks at the remote site are operated across a plurality of storages or a plurality of volume groups. A consistency group consisting of a secondary journal volume and a replica is associated with a journal group consisting of a primary data volume, a primary journal volume, a secondary journal volume, and a secondary data volume. Upon backing up a secondary data volume and forming a replica, the host system issues a backup time reservation command to a storage apparatus, and the storage apparatus creates a replica by comparing the time stamp added to the journal data and the backup reservation time.
    • 提供了一种远程复制系统,即使当远程站点上的任务跨多个存储器或多个卷组操作时,也能够保证远程站点处理的数据的时间排序。 由次要日志卷和副本组成的一致性组与由主数据卷,主日志卷,辅助日志卷和辅助数据卷组成的日志组相关联。 在备份辅助数据卷并形成副本时,主机系统向存储装置发出备份时间预约命令,并且存储装置通过比较添加到日志数据的时间戳和备份预留时间来创建副本。
