摘要
数据重要性不断提高,对数据保护提出了越来越高的要求。基于数据的细粒度保护,以最小的时间代价和存储代价来保护数据,并以最少的数据损失量来恢复数据,则是数据保护的追求目标。针对此需求,提出并设计实现了一套基于磁盘块的持续数据保护系统。该系统高效而灵活地实现了Windows操作系统下的磁盘数据的保护。测试表明,该系统在使用时对正常的业务影响很小;在灾难发生后可以在较短的时候内将数据恢复至可用状态。
Currently,electronic data has been becoming more and more important,which calls for more sophisticated measure for data protection.The goal of data protection is to provide fine-grain protection with least time and storage cost,and with least data lost after data recovery.For this,this paper have designed a block-based data protection system and implemented it,which can provide protection for Windows disk data in an efficient way.With experimental test,this paper found this system brings little negative inf...
