Disaster recovery method based on domestic database replkation technology

为提高物联网信息系统运行的稳定性与安全性,基于国产数据库复制技术,文章提出了一种新的灾备方法。确定灾备方法的运行逻辑,建立异地灾备数据库,并根据数据恢复策略构建数据恢复任务,可以实现基于国产数据库复制技术的灾备方案设计。仿真结果显示,应用该设计方法得到的复制数据最大差异量为0.53 Sequence,抓取时间为16.0 min,回放时间为60.3 min,生产端到灾备端的切换时间为4.31 min,灾备端到生产端的切换时间为4.18 min,支持轮换运行时长为213.21 h,在12 h内,最大的数据复制延时为1365 ms,说明该设计方法具有精准性与高效性,能够提高系统数据信息的安全性与完整性。

In order to improve the stability and security of the operation of the Internet of things information system,a new disaster recovery method is studied according to the domestic database replication technology.Determine the operation logic of the disaster recovery method,establish a remote disaster recovery database,build a data recovery task according to the data recovery strategy,and realize the disaster recovery scheme design based on the domestic database replication technology.The simulation results show that the maximum difference of replicated data obtained by applying the design method is 0.53Sequence,the capture time is 16.0min,the playback time is 60.3min,the switching time from the production end to the disaster recovery end is 4.31min,the switching time from the disaster recovery end to the production end is 4.18min,and the supporting rotation operation time is 213.21h.Within 12h,the maximum data replication delay is 1365ms,which shows that the design method is accurate and efficient,It can improve the security and integrity of system data information.
