摘要(Abstract)：
随着电力企业信息系统的不断发展,业务系统的数据量一直处于高速增长之中,如何对关键业务的海量数据实现高速高效的保护成为重要的问题。以浙江电力试验研究院虚拟化容灾备份系统的建设为实例,介绍了在现有软件、硬件和数据量的基础上,实现一个备份系统从传统物理带库等级到虚拟化等级的升级改造,从而实现信息系统快速、高效的备份与恢复,优化信息系统数据备份架构,提高数据保护的效率。
With the continuous development of electric power enterprise information system,the amount of data in business system has been growing rapidly.How high-speed and high-efficiency protection of massive data for key business can be achieved becomes an important issue.Illustrated with the example of the construction of virtual disaster recovery system(DRS) in Zhejiang Electric Power Test and Research Institute,this paper introduces the upgrading of a backup system from a traditional physical tape library level to virtual level based on the existing software,hardware and data volume in order to achieve fast,efficient backup and recovery of information system,optimize data backup architecture of information system,improve the efficiency of data protection.
