    • When data is updated in response to execution of an application by a host, an operation center apparatus records update history data into an update history file and updates a database. A remote copy apparatus consisting of network storages transfers and records the update history data via a network into a backup update history file at a transfer destination every time the update history data is recorded into the update history file by the operation center apparatus. When the operation center apparatus goes down, a backup center apparatus restores a management file for managing usage situation of the backup update history file from the backup update history file and, by reference to the management file, sequentially reads out the backup update history file until discontinuity of update history data is identified to update a database for backup.
    • 当响应于主机执行应用程序更新数据时,操作中心设备将更新历史数据记录到更新历史文件中并更新数据库。 由网络存储器组成的远程复制装置每当通过操作中心设备将更新历史数据记录到更新历史文件中时,通过网络将更新历史数据传送并记录在传送目的地的备份更新历史文件中。 当操作中心设备关闭时,备份中心设备从备份更新历史文件恢复管理备份更新历史文件的使用情况的管理文件,并且通过参考管理文件顺序地读出备份更新历史文件,直到 识别更新历史数据的不连续性以更新用于备份的数据库。
