This guide was validated on machines running Ubuntu 20.04, although it should generally work with any computers running a Linux-based operating system that have rsync installed. Then, copy each server’s public key to the other server’s authorized_keys file as outlined in Step 2 of that guide. Regardless of what types of machines you use to follow this tutorial, you will need to have created SSH keys on both of them. To set up these servers, follow our Initial Server Setup Guide. If you plan to follow this guide using servers, it would be prudent to set them up with administrative users and to configure a firewall on each of them. These two machines could be virtual private servers, virtual machines, containers, or personal computers as long as they’ve been properly configured. In order to practice using rsync to sync files between a local and remote system, you will need two machines to act as your local computer and your remote machine, respectively. In this tutorial, we’ll define Rsync, review the syntax when using rsync, explain how to use Rsync to sync with a remote system, and other options available to you.

It uses an algorithm to minimize the amount of data copied by only moving the portions of files that have changed. Rsync, which stands for remote sync, is a remote and local file synchronization tool.
