Using rsync for your website or server

So you have a website and you have ssh setup on your server. Rsync is a way of uploading and downloading files to and from your server. Here is how.

rsync is a simple way to copy files and folders between your local computer and server.

It not only makes file-transfer easy, but it allows you to build and maintain your website offline, then easily upload it to the proper directory on your server so you don't need to constantly be logged into your server to modify your site.

Installing rsync

Run the following on your server and on your local machine.

Run the following on your server and on your local machine.

apt install rsync

Uploading files with rsync

From your local machine you can upload files to your server like this:

rsync -avz /path/to/file landchad.net:/path/on/the/server

You will be prompted to enter a password. By default it will use the username that you are logged in with on you local machine. To use a different user, do this:

rsync -avz /path/to/file username@landchad.net:/path/on/the/server

Downloading file with rsync

Basically like downloading, you just swap the last two arguments, like this:

rsync -avz landchad.net:/path/to/file /path/to/file

Again, with a different username on you server:

rsync -avz username@landchad.net:/path/to/file /path/to/file

rsync -ruvzP /path/to/file root@example.org/path/on/the/server

You will be prompted for the root password and then uploading will commence.

If you omit root@, rsync will not attempt to log in as root, but whatever your local username is.

Options to rsync

In this command, we give several options to rsync:

-r – run recurssively (include directories)
-u – update files (do not reupload files that are not changed since last upload)
-v – visual, show files uploaded
-z – compress files for upload
-P – if uploading a large file and upload breaks, pick up where we left off rather than reuploading the entire file

Avoid using the commonly used -a option when uploading. It changes can transfer your local machine's user and group permissions to your server, which might cause breakage.

Scriptability

It's a good idea to build your website offline, then make an rsync script or bash alias like the one above to upload the edited files when you have made updates.

Password-less authentication

To avoid having to manually input your password each upload, you can set up SSH keys to securely idenitify yourself and computer as a trusted.

Picky trailing slashes

rsync is very particular about trailing slashes. This is useful, but can be confusing to some new users. Suppose we run the following wanting to mirror our offline copy of our website in the directory we use on our server (/var/www/websitefiles/):

rsync -ruvzP ~/websitefiles/ root@example.org:/var/www/websitefiles/

This will not actually do quite what we want. It will take our local websitefiles directory and put it inside websitefiles on the remote machine, ending up with: /var/www/websitefiles/websitefiles.

Instead, remove the trailing slash from the remote server location:

rsync -ruvzP ~/websitefiles/ root@example.org:/var/www/websitefiles

websitefiles/ has been replaced with websitefiles, and this will do what we want.

Downloading files with rsync

You may just as easily download files and directories from your server with rsync:

rsync -urvzP root@example.org:/path/to/file /path/to/file
