摘要
基于传统的文件同步框架(rsync)构建而成的文件备份中心存在着服务器负荷过重、网络传输数据过多等不足。通过对其架构做出改进,设计和实现一种新的文件同步系统(DFSS),系统采用在客户端加入卷影拷贝服务(VSS)功能,并在客户端通过使用快照来计算客户端文件和服务器文件之间的差异,从而达到快速计算文件差异、降低服务器计算量、减少网络传输数据量。
There is some shortcoming for implementing a network file-backup center based on the traditional file synchronization architecture (rsync) , such as the server's load is too heavy and the data transmitted on the network is too much. Design and implement a file synchronization system through improving the rsyne architecture, add the Volume Shadow copy Service on the client, and calculate the file difference between these different versions by using this service. In this way, it can calculate the file difference more quickly, bring down the amount of calculation on the server and reduce the data transmitted on the network.
