how to sync git repositories using redmine-git-hosting to github ?

[gu1llohm]

Dear Nicolas,

I'm trying to find the best way to synchronize repos from projects into github as backup ( read-only ). I was trying to use https://github.com/koppen/redmine_github_hook but i was not able to work with it.
Do you have any experience or recommantations to give me about it ?

Thanks for your help.

BR,
Guillaume.
