Well the bugtracker and additional features are not inside of the git repository. So they’d get lost. But each ‘git clone’ is a complete clone of the (source code) repository including all of the history of changes, the commit messages, dates and individual changes. That’s stored on every single computer that cloned the repository and you have a copy of everything locally. Though it might be out of date if you didn’t pull the latest changes. But apart from that it’s the same data that Github stores. You could just make it available somewhere else and continue.
