Who are we?
We are digital librarians. Among us are represented the various reasons to keep data -- legal requirements, competitive requirements, uncertainty of permanence of cloud services, distaste for transmitting your data externally (e.g. government or corporate espionage), cultural and familial archivists, internet collapse preppers, and people who do it themselves so they're sure it's done right. Everyone has their reasons for curating the data they have decided to keep (either forever or For A Damn Long Time). Along the way we have sought out like-minded individuals to exchange strategies, war stories, and cautionary tales of failures.
We are one. We are legion. And we're trying really hard not to forget.

I can imagine a containerized service that only runs, say, ssh which only runs a forcedcommand, like Borgbackup
And set up the container with the storage-opt option to limit space usage. It would make it harder to misuse the space or cpu, or break out into the hosting server.
You could go one step further and set up something like a tailscale/headscale network and only allow access over that, and limit the acls on the tailnet to only the ssh port. That should shield it from the Internet at large and also apple am absolute minimum of access to the other side.
I wonder if you could run the tailscale client within the container? Having it all together would make it actually usable.
I’m also looking at some of the distributed file systems out there, if one supports “m of n” connections to get the data, you could possibly use that to have the encrypted backups stored on multiple machines at once with more resilience.
