Most companies rely on a SaaS based source control solution (GitHub, ADO, GitLabs, Codeberg, etc.). While this helps with issues are code loss from an individual POV (your laptop dies, you delete something). How do you back it up at scale should something happen to the service?

I know people, rightfully, joke about GitHub’s uptime, but what if it were to go hard down for an extended period of time?

So lemmings, how would you back up an organization’s source control?

Edit: a lot of people are focusing on personal or home. I’m wondering about corporate level without having on-premise resources.
