Kopia isn’t exactly agent based but you can at least change settings/policies for different machines if you use kopia server. I use it to have a global exclude list basically on the machines I back up.

Huh, I was wondering how rrds would help…

Your readme looks super in depth, thanks for that! I haven’t watched the video yet but will later.

I didn’t see it mentioned from a quick glance, but is either sftp or ftps supported?
