Add a firewall rule to allow the backup server to get to the backup files using the "rsync" service

It is assumed that you have enabled a firewall on your IR server, if not please go to: http://wiki.lib.sun.ac.za/index.php/SUNScholar/Firewall and do so.

Then add the following firewall to allow the backup server to connect:

sudo ufw allow from %server-hostname% to any port 873

Replace %server-hostname% with the server hostname of your backup server.
