I've been extremely happy with Arq https://www.arqbackup.com/ for several years as a quiet backup solution, bring your own storage. I've done a few small restores and it's been just fine, and it automatically thins your backups to constrain storage costs.

Managing exclusions is something to keep vaguely on top of (I've accidentally had a few VM disk images get backed up when I don't need/want them) but the default exclusions are all very reasonable.

I like https://www.borgbase.com

It's set it and forget.

You will need to set it up for them, then you get an email (from borgbackup, not the client so it works when the client is not running) when a backup hasn't happened for a while.

As client there are more options now (like Vorta, from them), but I have had success with https://github.com/garethgeorge/backrest and the Restic backend.

Installed Carbonite on my parents’ computer something like 15 years ago, and it still works (every now and then my dad tells me he used it to recover from a bug or a mistake).

But I have no idea where the company currently sits on the spectrum from good actor to fully enshittified.

`rclone` with AWS credentials. Go make a bucket and a key that can read/write to it.

Set up your config to exclude common non-file dirs, or say "only `/Applications` and `Home` and that's about it. If it's a file then it's a file, and it will be synced up.
