    • When performing asynchronous remote copying, whether or not a disaster has occurred at a main site is judged at a remote site; and if the disaster has occurred, recovery processing is immediately started at the remote site. When asynchronous remote copying is performed between a controller and a controller, the controller transfers remote copy target data in a storage apparatus and command information via a remote copy channel to the controller; and after receiving the remote copy target data, the controller stores the remote copy target data in a storage apparatus; and if the controller fails to receive the command information within a set time period, the controller judges that a disaster has occurred, and then outputs the judgment result to a backup center server; and the backup center server executes recovery processing based on data in the storage apparatus when the disaster has occurred.
    • 执行异步远程复制时,在远程站点判断主站点是否发生灾难; 如果发生灾难,则在远程站点立即启动恢复处理。 当在控制器和控制器之间执行异步远程复制时,控制器通过远程复制通道将存储设备中的远程复制目标数据和命令信息传送到控制器; 并且在接收到所述远程复制目标数据之后,所述控制器将所述远程复制目标数据存储在存储装置中; 如果控制器在设定的时间内未能接收到命令信息,则控制器判断发生了灾难,然后将判断结果输出到备份中心服务器; 并且当发生灾难时,备份中心服务器基于存储装置中的数据执行恢复处理。
