1, Rsync IntroductionRsync is an open source, fast, versatile and excellent tool for full-scale and incremental simultaneous backup of local or remote data, and rsync software works on nunix/linux/windows multiple operating systems.Official website: http://www.samba.org/ftp/rsync/rsync.htmlRsync English is all called remote rynchronization.Features of the Rsyn:1)

First, the basic introduction of rsync1. What is rsyncRsync is an open source, fast, multi-functional, incremental local goods remote data mirroring synchronous backup of excellent tools, rsync use and unix,linux,windows and other platforms2, the characteristics of rsync1) Support for copying special files2) can have exclude specified file or directory3) can maintain the original file or directory permissions4) can achieve incremental synchronization,

Rsync is so convenient for file backups that I feel I have to install it on my own server. The rsync server here is a simple and rough configuration (directly on the code), for details do not do in-depth discussion, but it is certain that the server must be able to run up, for the novice this is the most important, is not it?A What is rsync　　

, and we'll analyze all of its options below.The command format for rsync can be in the following six ways:rsync [OPTION] ... SRC DESTRsync[option] ... SRC [User@]host:destrsync [OPTION] ... [user@] HOST:SRC DESTrsync [OPTION] ... [user@] HOST::SRC DESTrsync [OPTION] ... SRC [user@]host::D ESTrsync [OPTION] ... rsync://[user@]host[:P ort]/src [DEST]For each of the above six command formats,

After the rsync server configuration is over, the next step is to issue an rsync command on the client to enable the server-side files to be backed up to the client. Rsync is a very powerful tool, and its commands have many feature options, and we'll analyze all of its options below. The command format for rsync can be

1. What is rsync? Rsync, remote synchronize is a software that implements remote synchronization. It can keep the permissions, time, soft and hard links, and other additional information of the original file while Synchronizing files. Rsync uses the "rsync algorithm" to provide a fast way to synchronize files between c
