I use Carbon Copy Cloner to back-up our household computers to local external drives and an off-site Apollo Cloud2 Duo. Everything works fine with the exception of our mid-2019 MacBook Pro to the Apollo. Everytime the CCC script launches for the back-up to the Apollo, the MacBook Pro fan goes berserk and the back-up fails. This does not occur on any other computer (MacMini and a 2017 MacBook Pro) nor when backing up the same 2019 MacBook Pro to local external drives.
