问题
I want to setup a gitlab server on my local server and also use gitlab cloud as an offsite backup. Whenever a developer pushes their work i want it to go to both gitlab servers. I will do this using the following git commands
git remote set-url --add --push origin git://my_local_repo_url
git remote set-url --add --push origin git://my_gitlab_com_repo_url
I am concerned though that the two servers could go out of sync easily.
- What would happen if one of the servers was down during the push so one succeeded and one failed? How would i handle this?
- What if a developer forgot to add one of the remote URLs so only one of the servers was being pushed to and then the second remote URLs was added. What would happen the next push and how would i handle it?
- What other problems might I run into?

As mentioned in "pull/push from multiple remote locations", a failed push (because one of the remote repos, for any reason, was not available) can be fixed at the next push: the commits which were not pushed last time are pushed (in addition of the new ones) in the next push.
Even of the developer add the second remote later, as long as that second remote reflect what is in the first, that is OK: only new commits will be pushed (to both)
But the problem is:
- divergent history (when one of the remote has commits that you do not have yet): you need to rebase on top of
origin/master(in a fetch,originalways refer to the first url): then you can push - divergent remote (when both remote have different set of commits, because of two different history pushed to each one): you would need to
push --forceto one of those remote in order to rewrite/reset its history.
