摘要
通过对容灾系统多副本备份方式的分析,为有效解决数据的快速备份和恢复问题,利用P2P资源共享的思路,提出了数据文件副本在网络中多点之间传输与共享的算法思想,并进行了仿真测试。试验结果表明,多源快速备份和恢复算法(MSB&RT)极大提高了数据传输的效率,为关键数据的恢复提供了更为可靠的保证。
Through analyzing the way of multi-transcriptions backup in the Disaster Recovery system, and effectively solves the question of the data fast backup and restoration, a algorithm thought which to transmits and shares the data file transcription among network multi-nodes is proposed. Here we use the resource sharing idea of P2P and carried on a simulation test, the result indicate that the Multi-Source Backup and Recovery quick Transmission Algorithm （MSB＆RT）extremely enhance the efficiency of data transmission and reliably guarantee the essential data recovery.
