To allow your local PC to authenticate, the public SSH key that was generated in the previous section needs to be copied over to the remote server. The -m option simply tells Linux to create a home directory for our new user. The above example uses the username rsync, but you may change it to anything you wish.
Login to the remote server via SSH and run this command: sudo useradd -m rsync Although not required, for this guide we will create a new user on the remote server for rsync connections and to store all backup files.
