JetBackup will register your license once you activate it. The license will register your server IP. If you migrate/replace the server, you will need to reissue the license through our client's area.
Login to our clients area, from the top menu navigate to "Services" -> "My Services".
Choose your JetBackup product (click the "View Details" button).
Under "Actions", click on "Reissue License".
Please execute the following command from your server's CLI as root user to validate your license against our licensing servers.
jetcli backup --license
