Abstract: With the transformation and upgrading of education informatization, the security of information system data storage and disaster recovery protection have become the hot issues of school security protection. How to ensure the rapid recovery of data after a catastrophic event and ensure that the information system data is not lost has become an important topic of school network security. The CDP technology is a comprehensive disaster prevention technology. This paper introduces the backup principle, recovery process and key technical points of CDP technology. Aiming at the data disaster recovery requirements of Guizhou Vocational College of Economics and Business, it designs local backup systems and remote disaster recovery systems, and puts forward a design method of data disaster recovery system based on CDP technology, which has achieved good results in practical work.

Keywords: CDP technology; backup technology; recovery technology; disaster recovery system

隨着学校信息化教学转型升级,学校信息化建设、管理和应用能力成为评价学校办学能力的指标之一。信息系统的安全稳定运行成为当前信息化教学的热点和难点工作,如何做好信息系统和数据的容灾备份工作,当出现灾难性系统故障时,如何保障数据不丢失,快速恢复和启动系统成为学校的关注点。

1  学校在数据容灾中存在的困境

1.1  数据容灾系统缺失

学校在信息化建设过程中,大部分学校只重视信息系统的建设,在系统的管理和安全运维上缺失。信息系统的建设大多数基于传统的单机服务器模式,没有进行虚拟化云存储集中统一管理,数据备份只能做传统的数据库备份和文件备份,而且是定期备份,数据不能做到实时全量和增量备份。信息系统一旦出现灾难性故障,数据恢复需要专业的运营团队才能完成,数据缺失现象严重。……
