Interesting question, considering all Eclipse repos are mirrored on GitHub.
But, as illustrated by the recent (April 2013) article from Wayne, the re is no automatic GitHub way to mirror a repo.
As far as I know, GitHub provides no mechanism to schedule a regular pull (correct me if I’m wrong), which means that it would become our responsibility to push to the GitHub clone.
See also bug 402183.
So a script on a VPS (ie, something you setup) remains the surest way to implement this.
Building on "HowTo mirror your git repository on Github", you would need your own local clone, with a script which would:
- regularly pull from the GitHub repo
- push to the mirror on Github
Update 2015 (2 years later): a tool like beefsack/git-mirror
(in go) is:
designed to create and serve read-only mirrors of your Git repositories locally or wherever you choose.
A recent GitHub outage reinforces the fact that developers shouldn't be relying on a single remote for hosting code.
