The person you're replying to said "Syncthing ... and ZFS + znapzend + rsync.net" though. You're ignoring the rsync.net part. I have something similar; it's Nextcloud + restic to AWS S3, but it's the same principle. You can give people the convenience and human-comprehensibility of sync-based sharing, but also back that up too, for the best of both worlds. Though in my case the odds of me needing "previous versions" of things approach zero and a full sync is fairly close to backup, but, even so I do have a full solution here.
