Objective

Rsync is a data mirroring and Backup tool under the Linux,unix system, have the ability to make local and remote host files, directories, fast synchronous mirroring, remote data backup and so on. During synchronization, you can delete or update the local machine data according to the data changes on the remote server. Synchronizing data does not have to be delivered in full, greatly increasing the speed of synchronizing and backing up files. Also, in the context of network security, it can be set to SSH transmission mode. Remote host (rsync Server) for rsync daemon mode, opened will be open TCP4 873 port, waiting for the local host (rsync client) connection, the connection when the remote host to authenticate, to confirm the entry of legitimate users, began to carry out data transmission, The entire data is backed up to the local host on the first transmission, and when the next transmission is added, the corresponding parameters can be adjusted according to the data changes of the remote host. This article is just a simple application of RSYNC software operation documents, mainly for beginners a preliminary introduction, if you are in the application, what better advice and suggestions, please mail me. I will continue to update this document, thank you! :)
