This has appeared on HN a few times.. I'd really like to use tarsnap but it's simply too expensive to be viable (to which I guess the response is: don't use tarsnap for full-backups -- but this makes it practically useless as far as diminishing the complexity of my current backup scheme[0]).

I'm a little unclear - does Duplicity run on macOS?

  Yes, there's a Homebrew package for duplicity.

How much data are you trying to store?

Have you found services with more favorable costs? I'd be curious to hear what they might be. Besides that, you might just consider replicating to a mini-computer of some sort in another location that you have permission to use like a friend's or relative's house. A raspberry pi connected to an external drive should probably do the trick. Duplicity looks like a good tool by the way, thanks for bringing it up.

I also use duplicity for my backups. I don't use the S3 option, preferring to write to my own storage, but if I were to turn on S3, what exactly does Tarsnap give me beyond what I'm already getting? Other than an additional middleman taking a cut?

  Duplicity isn't bad; I often recommend it to people who want something similar to Tarsnap but don't want Tarsnap itself. The biggest disadvantage to Duplicity is that it has a far more constrained archive management model -- with tarsnap you can delete any archive at any time, but Duplicity works with a "full plus incrementals" model, which means that (a) you can't delete an archive without deleting the archives which "depend" on it, and (b) you'll inevitably need multiple full archives. Other points which are probably of lower importance to most users: Duplicity's website and documentation is even worse than Tarsnap's; and they rely on GPG, which has a pretty lousy security track record.
