Edit /etc/passwd and replace www-data’s shell with /bin/bash rather than /usr/sbin/nologin.

What the above does?

Allows the www-data user to successfully log in. This is changing the “login shell” which is a good keyword to search for to learn more.

Add the backup server’s SSH key to /home/www-data/.ssh/authorized_keys.

Do you mean Public key here?

Yes. Private keys should (basically) never be copied/shared anywhere outside of their host machine.
