Design and Implementation of a File Synchronization System Based on Difference
Xiaoqin Hu · Computers & Security · 2009
The traditional file synchronization architecture(rsync) has some shortcoming for implementing a network file-backup center, 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 rsync 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.
