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.
