rsync over ssh

1. IntroductionRsync is a remote data synchronization tool that enables one rsync server to back up multiple client data at the same time, requiring Scp,ssh,daemon support with a default port of 873.Rsync + Crond can achieve data timing synchronization, Rsync + inotify can achieve real-time data synchronization.The

and devices. 2) You can exclude the synchronization of specified files or directories, which is equivalent to the packaging command tar. 3) You can keep the permissions of the original file or directory, and keep all attributes such as time, hard and soft links unchanged. 4) incremental synchronization is implemented, that is, only the changed data is synchronized, so the data transmission efficiency is higher. 5) You can use rcp, rsh, ssh, and other

Note the clock synchronization between the two machines. -- Progress indicates that the detailed progress is displayed, -- Delete: if the server deletes the file, the client also deletes the file to ensure true consistency.

How to use rsync under LinuxSpit Groove　　After summing up the SCP yesterday, I saw that there was finally a talk about Rsync, a cloud: Curiosity killed the cat. With the attitude of learning to find out the rsync, and then carried out some simple study. Here are a few common commands. The scp:12 of the previous article is a file for the SCP transfer of chestnuts.
