I think that bundles (see git-bundle) would be what you want (please read GitFaq/GitTips/"Git in Nutshell" for explanation and use cases).
"git fetch" (perhaps using bundle) would save state of refs (heads, remote branches, tags) and object repository. To save state of working area and index I think it would be best to use 'git-stash' before creating backup, and unstash after it; see documentation for git-stash. What is left is: reflogs, configuration, hooks, grafts and shallow, repository local excludes file, repository local attributes file[*1*].
