持续数据保护技术的优势分析

ANALYSIS ON ADVANTAGES OF CONTINUOUS DATA PROTECTION TECHNOLOGY

随着数据在如今信息社会中的作用越来越重要,数据的保护变得必不可少。新兴的数据保护技术持续数据保护技术CDP(Continuous Data Protection)一出世就成为关注的焦点,它用低成本和低复杂性提供很好的恢复点对象RPO(Recovery Point Ob-jective)和恢复时间对象RTO(Recovery Time Objective),增强了数据保护能力,实现了数据的快速恢复,增强了业务的连续性,成为对传统数据保护技术的重大突破。对CDP技术进行介绍,分析出传统数据保护技术如备份、复制和快照技术的劣势,总结出CDP技术与传统数据保护技术相比具有的优势以及CDP是如何解决传统数据保护技术的缺陷。

With the increasing importance of data in today＇s information society,data protection technologies have become essential.The new data protection technology,Continuous Data Protection（CDP）,becomes the focus of people when it emerged.It enhances the data protection capability,achieves rapid recovery of data,enhances services continuity and provides good RPO and RTO with its low cost and low complexity.This paper introduces CDP technology first of all and then works out the disadvantages of traditional data protection technologies,such as backup,replication and snapshot technology and the advantages of CDP technology.Also,this paper points out how CDP overcomes the weaknesses of traditional data protection technologies.
