摘要 rsync算法作为文件同步算法得到了广泛的应用,但是存在与服务器交互频繁、不适用特定文件等问题。设计和实现了一种基于文件类型的远程文件备份系统,通过文件类型的筛选避免特定文件的差异计算,在本地缓存文件摘要信息,将差异计算提前至文件上传前,减少了客户端与服务器间的交互。这样,不仅减少了差异备份中网络传输量,也减少冗余的差异计算。 rsync algorithm as file synchronization algorithm has been widely used,but its problem is frequent interaction with the server,not for a particular file and so on.This paper designs and implements a Remote backup system based on file type,using file type filtering to avoid calculating file summary information of of a specific file,through calculating the difference of the file before uploading to reduce the interaction between server and client.This not only reduces the amount of data transmitted,but also reduces the redundancy of the differences＇ calculation.
