Rsync is a handy utility for transferring files on MacOS and Linux filesystems, to and from remote servers and local machines.
For example, if you wanted to download a backup file from a Linux server, you could use
rsync to transfer that file to your local machine, using SSH with Public Key authentication.
Here's some of my commonly-used rsync examples for quick reference.
Download a file from a remote server to a local machine, with SSH key authentication:
rsync -Pav -e "ssh -i $HOME/.ssh/key.pem" username@hostname:/path/to/source/file.ext /path/to/local/destination/
I've typically seen this error when downloading files from a remote server, where the remote server doesn't have
rsync installed. This is common on AWS Lightsail LAMP stack instances.
For my use-case in AWS Lightsail I was able to install Rsync using
sudo apt-get install rsync
