GRSYNC CENTOS HOW TO

This output now demonstrates that the directory itself was transferred, rather than only the files within the directory. You’ll combine the a, n, and v flags in the following command: The -v flag, which means “verbose”, is also necessary to get the appropriate output. Rsync provides a method for doing this by passing the -n or -dry-run options. The outcome would create a hierarchy like the following: ~/dir2/dir1/Īnother tip is to double-check your arguments before executing an rsync command. Without the trailing slash, dir1, including the directory, would be placed within dir2. This trailing slash signifies the contents of dir1. Please note that there is a trailing slash ( /) at the end of the first argument in the syntax of the the previous two commands and highlighted here: Run the same command as the previous example, this time using the -a flag: It’s more commonly used than -r and is the recommended flag to use. This flag syncs recursively and preserves symbolic links, special and device files, modification times, groups, owners, and permissions.

To sync the contents of dir1 to dir2 on the same system, you will run rsync and use the -r flag, which stands for “recursive” and is necessary for directory syncing:Īnother option is to use the -a flag, which is a combination flag and stands for “archive”.

You also have an empty directory called dir2.

The syntax for rsync operates similar to other tools, such as ssh, scp, and cp.įirst, change into your home directory by running the following command: Due to its ubiquity on Linux and Unix-like systems and its popularity as a tool for system scripts, it’s included on most Linux distributions by default. Rsync is a very flexible network-enabled syncing tool. 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.
