摘要
随着国网SG186工程的实施,电力系统信息化程度不断提高,对于海量生产数据运维工作的管理提升已经到了十分紧迫的程度,国家电网公司正在大力开展数据中心的建设工作。数据中心的重要作用是进行数据容灾,通过建立异地的数据系统,为本地关键应用数据提供可用复制备份,而数据容灾技术的选择是数据中心建设中十分重要的一环。本文对基于备份复制级、存储级等几大数据容灾技术进行了介绍与对比分析,为数据中心建设中可能采用的各种技术的特点和优劣做了一一阐述。
Along with the further implementation of SG186 Project of State Grid,the informatization of power system has been continuously improved.To improve the management of maintenance of mass dada,the construction of data center has been developed rapidly.To achieve the disaster recovery task is an important function of data center.Useful backup data could be produced for local imformation of key applications by building remote disaster recovery system.It is very crutial to select disaster recovery technology.Introduction and comparison has been made about several recovery technologies,such as ones based on backup data replication or based on storage replication,etc.
