The encryption can be a simple password (please use a strong one) or you can utilise your HESA secure key, or a more secure, self-generated one. Either way, it's obviously important that you don't forget or lose your password or key. The result is that no matter what happens to your backup, your patient records cannot fall into the wrong hands.
Some encryption methods will increase your backup time, but this is a straight forward process. Please contact us to arrange to have your backup upgraded to a secure one.
