Rsync is a data image backup tool in Linux. It can be seen from the software name-remote sync. Rsync supports most Unix-like systems, including Linux, Solaris, and BSD. The latest version of rsync can be found at http://rsync.samba.org/rsync. Its features are as follows:1. images can be used to save the entire director
What is rsync?Rsync is a fast incremental file transfer tool. It can be used for internal backup of the same host. We can also use it as a network backup tool for different hosts. This article mainly describes how to use an rsync server to implement file transmission, backup, and mirroring. Compared with tar and wget, rsync

Recently need to implement a dynamic backup of the files on the server, I do not want to do a manual backup every time, find a lot of information on the Internet, found that using rsync can be achieved, if you want to achieve real-time synchronization, you can also use the rsync+inotify combination, this article is done in combination.Let's introduce Rsync and in

May 2005, Business Network in the online stage. However, due to the overall reason has been slow to go online. System basic functions have been implemented, but as a business network as a whole, file synchronization is not completed. I am not very busy this time. I have some interest in this piece, so I decided to touch it.
The beginning of everything is difficult, never contacted what synchronization and so on, how to start? Fortunately before the mail system, know the Eyou be

Inotify + rsync for real-time file synchronization and inotifyrsync
Rsync is used in the project to implement file synchronization, but inotify + rsync is not as good as real-time synchronization. Next, let's experiment.
Inotify is a new feature introduced from Kernel 2.6.13. Therefore, we need to first check whether our linux system supports inotify.

First, IntroductionIn the configuration of HA, you need to configure the configuration of multiple nodes, the configuration of the nodes are often similar to duplicate, perhaps through the SCP and other means to achieve, but each change requires manual SCP also seems troublesome, this way we can use Rsync to achieve file synchronization.When using Rsync+crontab to do timed synchronization, the main server s

Rsync (synchronize) is a remote data synchronization tool that synchronizes files between local and remote hosts using the rsync algorithm.The benefit of rsync is to sync only two different parts of the file, and the same part is not delivered. Similar to incremental backups,This makes it much more time-consuming to deliver backup files or sync files to the serve
