数据中心灾备系统建设技术实践

Technical Practice of Data Center Disaster Recovery System Construction

为了保障信息系统业务的连续性、可靠性、完整性以及安全性,并且满足三级等保要求,人们使用数据中心容灾和备份保护数据。文章以某省政务外网数据中心灾备系统建设为例,探讨生产中心业务数据备份、同城双活中心业务数据备份、异地灾备、生产中心至双活中心应用容灾方案以及数据中心容灾故障切换,通过“两地三中心”的模式保障某省政务信息系统的连续性及安全性。

In order to ensure the continuity,reliability,integrity,and security of information system business,as well as meet the three-level guarantee requirements,data center disaster recovery and backup have become important means of data protection.This article takes the construction of a disaster recovery system for a provincial government extranet data center as an example to explore the main research topics:production center business data backup,local dual activity center business data backup,remote disaster recovery,application of disaster recovery solutions from production center to dual activity center,data center disaster recovery and fault switching,and the implementation of a"two places and three centers"model to ensure the continuity and security of a provincial government information system.
