摘要
随着数据增长速度的不断加快,数据可用性变得比以往任何时候都更加重要。持续数据保护是一套数据灾难恢复方法,它可以捕获或跟踪数据的变化,并将数据恢复到任意时间点。在改进数据压缩算法和系统架构的基础上设计并实现一个基于iSCSI的持续数据保护系统。对系统进行数据测试结果显示该系统很好地解决了传统持续数据保护系统中数据占用空间大、恢复时间慢、可靠性低的缺点,能很好地将数据恢复到任何时间点,并给出简要的分析。
With the high-speed of data increasing, data availability becomes more important than ever before. Continuous data protection is a data disaster recovery method which can capture and monitor data changes and recover data to any point in time. We proposed a design of iSCSI based continuous data protection system based on improvement of data compression algorithm and system structure. This system is better in space saving, quick recovery and reliability comparing with tradition CDP system from our testing data and analysis, as presented in the brief analysis of the paper.
