Most importantly it would actually reveal the lie they are all trying to sell. Why would you need backups if it's so useful and stable? I'm not going to ask it to nuke my hard drive after all.

If you don't have the whatever to do it with Linux and rsync, pay someone like Acronis or Arq to deal with it for you.

Good thing this is not an average user then. This is someone programming a computer, which is a skill that requires being more than simply a user.

I'm sorry, but how low is the bar when "make backups" is "too difficult" for someone who's trying to program a computer? The entire point of programming a computer is knowing how it works and knowing what you're doing. If you can't make backups, frankly, you shouldn't be programming, because backups are a lot easier than programming...
