It seems like if there's an option to use remote backup in the config, yet the keys get erased every time it's upgraded that would be a bug. However , I am new to dev on VYOS, so classify it as makes sense for the team and I'll hope it get implemented at some point. 👍

I disagree, being that there's a command and associated config entry to backup config to a remote ssh server. This config option requires key based authentication. It would seem that the backup function puts this in- scope as a bug. Everyone who uses the remote configuration backup to an external ssh box is affected.

This would be the key's themselves and known_hosts, stored in the non-root user folder. The prompt during upgrade seems to indicate it'll copy them over. However, whenever I upgrade, I have to manually perform ssh-keygen and ssh-copy-id again for my backup server to allow my config backup to work.
