连续数据保护技术应用研究

新兴的持续数据保护技术基于无缝备份和还原技术，可以实现数据的实时备份，以及备份故障发生瞬间对任意时间点数据的快速恢复，从而保障客户的业务连续性需求。目前市面上已经出现了一些基于该类技术的产品如容灾网关DR3000等。仔细研究此类技术及产品的特点，并尝试将其应用于安徽X烟草公司的灾备系统建设。实验及实践应用表明：此类方案具有能最大限度减少容灾对生产系统的影响、不改变原有架构、恢复操作反映快、可对任意时间点进行数据恢复等特点。

Continuous Data Protection and Its Applications

The new Continuous Data Protection technology, based on seamless backup and restore technology, can achieve real-time data backup, and the rapid data recovery at any point in time the moment backup failure occurs, so as to protect the customer’s business continuity requirements. There are some products based on such technologies in the market, such as disaster recovery gateway DR3000 The author made a careful study of the characteristics of such technology and products and tried applying it to the disaster recovery system construction in Anhui Tobacco Company. Experiments and practices show that such schemes are of such characteristics as minimizing the disaster impact on production systems, without changing the original structure, quick reflection of operation recovery, and recovering data at any time.
