基于Internet的高效文件备份方法

High-efficiency File Backup Method Based on Internet

针对当前文件备份领域中存在备份效率低、速度慢的问题,提出一种基于差异的远程文件备份方法。改进传统Rsync算法,实现差异文件的计算功能,从而减少网络数据传输,保证传输的高效性。实验结果表明,与传统文件备份方法相比,该方法能减少网络流量,提升备份与恢复的效率。

Aiming at the problem of low efficiency and slow speed in file backup area,this paper proposes a remote file backup method based on files difference. Through improvement of traditional Rsync algorithm,it achieves the differences of document in calculation functions,reduces the data transmission network to ensure the transmission efficiency. Experimental results show that this method can significantly reduce network traffic and greatly enhance efficiency of backup and recovery compared with traditional file backup method.
