数据容灾备份与恢复的关键技术及应用研究

随着我国网络技术的不断发展和普及，人们对于网络的依赖程度也越来越大，社会各个企业对于网络数据的储存量越来越多，因此数据的安全工作就成为了数据保存中的重中之重本文通过对数据容灾技术重要性和必要性进行大致的介绍，并综合的阐述了数据容灾备份与恢复的关键技术，最后从数据定期备份、数据定期备份和关键数据的单独备份、关键数据备份的连续恢复、数据实时备份和异步更新、网络数据影像五个方面.对数据容灾备份与恢复的应用模式进行了科学合理的探究，给数据容灾备份与恢复的关键技术及应用研究带来了积极的指导意义

The key technology of data disaster backup and recovery and application research

along with the continuous developnlent and popularization of network technolog＇y, people depend on the degree of network is becoming more and more big, the social each enterprise for network data storage is increasing, so the security of data becomes the top priority in the data.Disaster based on the data of technical importance and necessity of roughly, and expounds the comprehensive data disaster backup and recovery of key technolog＇ies, and finally fi＇om the data backup, data backup and regularly regularly key data backup, backup critical data to a single continuous real-time backup and restore, data asynchronously updating, network data image in five aspects.The application of data disaster backup and recovery mode has carried on the scientific and reasonable to explore, to the disaster data backup and restore the key technology and application research of positive guiding significance.
