摘　　要：随着信息化普及程度提高,人们对信息系统的安全性、连续性也越来越重视。近年世界进入一个灾难多发时代,美国9.11事件、东南亚海啸、汶川5.12地震、日本3.11大地震等,无论是自然灾害还是战争,一旦发生往往会给信息系统带来灭顶之灾。尤其是在军事、金融等重要领域,这些领域的数据信息往往关系着国家安全和经济命脉,一旦遭遇数据灾难,将会给国家安全稳定带来严重威胁。因此,数据灾难备份系统的建立作为防止数据灾难的最后防线,其作用越发重要了。本文探讨比较了传统的灾难备份与恢复技术和连续数据保护技术,重点研究了连续数据保护技术的概念、原理及特点,并对灾难备份与恢复技术的发展做了一定的思考。along with the informationization popularizes degree improve,people on the information system security,continuity is also more and more attention.In recent years,the world into a disaster of multiple times,the United States in 9.11 events,5.12 Southeast Asian tsunami,Wenchuan earthquake,Japan 3.11 earthquake,whether it is natural disaster or war,once happen often to bring the crowning calamity information system.Especially in the important fields of military,financial and so on,these field data information is often related to national security and economic lifelines,once encounter data disaster,will bring a serious threat to national security and stability.Therefore,the establishment of data disaster backup system as the last line of defense to prevent data disaster,its more important role.This paper discusses and compares the disaster backup and recovery technology and traditional continuous data protection technology,focuses on the concept of continuous data protection technology,the principles and characteristics,and the disaster backup and recovery technology developed to do some thinking.
