As the total size of files is huge, When I am trying to push to github:

git push --mirror origin --verbose
Enumerating objects: 66689, done.
Counting objects: 100% (66689/66689), done.

Total 66689 (delta 40316), reused 66689 (delta 40316), pack-reused 0 (from 0)
fatal: the remote end hung up unexpectedly
Everything up-to-date

Believe I should be pushing in parts.
Appreciate all the help.
