I was writing a similar cli tool [1] to manage the git repositories on my own server. If you want portability, it should be fairly easy to write the cli interface in plain sh or bash, especially when most of the operations could be done on the server side. I am not sure if there is a reason to use a compiled language for this.

I think the point is not about backups. It is really, really easy to set up a remote git repository. Everything is nicely documented in chapter 4 of Pro Git [1]. Because a git remote is nothing more than a plain directory, you could serve a git repo anywhere you could store files, even on your own disks.

If multiple people need push access to a private repository, just serve a central repository as on a VPS and use SSH for authentication. I am not sure if there is a reason to use a third party hosting service for this, especially when hosting private repos.
