Self-hostable, but it seems like an absolute behemoth of an application if their “non-production-use-only” docker-compose file is to be believed, and I couldn’t find any production-ready deployment instructions on a quick skim. No obvious signs of federation and I didn’t see anything on their roadmap, not sure it would make a lot of sense for this though.

Love the diagonal belts & power poles.

Borg or the like with ‘hardcoded’ plaintext/regularly full-disk-encrypted key is acceptable. Someone that has your unencrypted private key sitting on your server has almost certainly already obtained access to the entire set of data you’re backing up, with the backup key itself only meaningfully guarding access to older backups.

The more important thing is to securely keep extra copies in case the server fails. I keep mine in a group in my password manager, one per repo.
