Some other comments mention that you can just clone your git repositories and use that a backup, but that's not practical when you're using git workflow as a core part of running your development team.
Relying on external services is never a good business move, so the a solution is to use GitHub Enterprise, which lets you run a private copy of the GitHub site on your own servers, with your own backup solution and security provisions.
Maybe this is what your coworker is advocating.
