Question

I’m trying to hack git to do backup for me. The data is so large relatively and I cannot afford a working copy and a git repo on any of my hard drives.

So, I need to git add/commit to a bare repo from a non-git folder.

• Hard drive 1: working copy / non-git
• Hard drive 2: bare git repo

Goal: commit from hard drive 1 to hard drive 2

Answer 1

No need for a bare repo.

you can specify a different git folder:

git --git-dir=/other/drive/some/path add

alternatively you can specify a different working folder:

git --work-tree=/other/drive/some/path add

or combine them together to execute from arbitrary location.

Beware that not all commands work with this parameter. Stash is one.
