Rsync Introduction
Rsync is an application software in Unix. It can synchronously update files and directories of two computers and use differential encoding to reduce data transmission. An important feature in rsync that is not seen in most similar programs or prot
Rsync is a data image backup tool in unix-like systems. It can be seen from the software name-remote sync
Its features are as follows: Images can be used to save the entire directory tree and file system.It is easy to maintain the permissions, time, and soft links of the original file.Installation without special permissions.Fast: During the first synchronization, rsync copies all the content, but transfers

1) Software Overview
Rsync is a remote data synchronization tool that allows you to quickly synchronize files between multiple hosts through the LAN/WAN. Rsync is a tool used to replace RCP, which is currently maintained by rsync.samba.org. Rsync
First, check whether there is rsync. If there is no rsync, an rsync will be installed.

Then create rsyncd. CONF file, and add the following content (the file does not exist by default) [[email protected] backup] # Cat/etc/rsyncd. conf # rsync_config _____ start # Created by chensiqi 13:40 2017-3-6 # blog: http://www.cnblogs.com/chensiqiqi/##r
Background
Our company is using Inotify+rsync to do real-time synchronization to solve the problem of distributed cluster file consistency. But when the Web files more and more (millions number of small files, such as html,jpg), synchronization is more and more slow, simply do not real-time, according to the online tuning methods have tried, the problem is not resolved. After my careful research, and finally the slow core of the study to understand,

Purpose: in order to achieve real-time synchronization, we use INotify to monitor the changes in the directory that need to be synchronized, INotify is just a module of monitoring file changes in the kernel, provides the API for monitoring file changes, and to connect this API, The Inotify-tools tool needs to be installed. Can realize the new file, delete, modify, change attributes, etc., the function is very powerful. Now requires a server as a publisher to put the changed files through

Rsync is a remote differential data synchronization tool that copies one copy of data to another machine. Its synchronization feature is that, in the entire file domain, only changed files are synchronized according to the file pattern calculated based on The Rsync algorithm, but when synchronizing the entire domain, it will calculate the features of all files in the entire domain, so that it takes a lot of

This site has been missing a similar tutorial. I will add it today. Rsync is a remote data synchronization tool. You can refer to the previous article Rsync remote data synchronization commands in linux and how to use them. however, after the data is updated, the data still needs to be manually synchronized and cannot be automated. You can configure rsync + innot

There are two machines. One is called a server and the other is called a backup machine. How can we copy the server data to the backup machine on a daily or regular basis? The powerful functions of rsync will be used here.

Considering the security of server data, I consider adding a backup server to achieve better redundancy through data synchronization.Linux has a very good command. Rsync can implement differential backups, so let's say how it's used:The Rsync service is not turned on in the installation of Ubuntu default installation. There are 3 steps to be made:1, modify the/etc/default/
