Since we're on HN. Use something like restic and a cron job backing up to something like blackblaze. Yes, it's the cloud, but they don't control the backup software (it's open source, not developed by them, using public APIs) or the encryption keys (protected by a passphrase client side, use a good one). There may be less programmery equivalents of that, which have scheduling built into the backup tool and so on. Just recommending what I've used. (This advice applies to general purpose computers, not sure if there's an equivalent for android or iOS)
