I need to be able to use a script to backup some IoT device I am working on, I usually use scp but in a script I would use an identity file, but this would rewuire me to copy the public key of every device to the backup server. I expected there would be an option for the backup server to provide a public key that each client would use to to authenticate, but can't find any such facility.
Am I going down the wrong track or have I missed something.
If I have thousands of clients, it is not practical to copy the public key of every device to the bakup server. Is ther a better idea ?
Thanks for any guidence.
