Rsync Server Setup

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

　　Rsync,remote Synchronize as implies meaning that it is a remote synchronization software, it synchronizes files at the same time, you can keep the original file permissions, time, soft and hard links and other additional information. Rsync uses the rsync algorithm to provide a quick way for file synchronization between a client and a remote file server, and it can be transferred via SSH, so it's very confidential and it's free software.

Rsync includes some of the following features:

1. Can update the entire directory and tree and file system;

2. Selectively maintain symbolic chain, hard link, file belonging, permission, equipment and time, etc.

3. For the installation, no special permission requirements;

4. For multiple files, the internal pipeline reduces the delay of file waiting;

5. Can use rsh, SSH or direct port as the transmission port;

6. Support the anonymous rsync synchronization files, is the ideal image tool;

Configuration of 2.rsync

Rsync mainly has the following three profiles rsyncd.conf (Master profile), Rsyncd.secrets (password file), RSYNCD.MOTD (RYSNC server information)

Server configuration file (/etc/rsyncd.conf), the file does not exist by default, create it.
