Git clone particular version of remote repository

I cloned a remote git repository about a month ago. The remote repository has undergone many changes and has now become unstable. Now I need another copy of the repository, version identical to the one I cloned a month ago.

How do I do this?

You could "reset" your repository to any commit you want (e.g. 1 month ago).

Use git-reset for that:

git clone [remote_address_here] my_repo
cd my_repo
git reset --hard [ENTER HERE THE COMMIT HASH YOU WANT]

You Can use simply

git checkout  commithash

in this sequence

git clone `URLTORepository`
cd `into your cloned folder`
git checkout commithash

commit hash looks like this "45ef55ac20ce2389c9180658fdba35f4a663d204"

Use git log to find the revision you want to rollback to, and take note of the commit hash. After that, you have 2 options:

1. If you plan to commit anything after that revision, I recommend you to checkout to a new branch: git checkout -b <new_branch_name> <hash>

2. If you don't plan to commit anything after that revision, you can simply checkout without a branch: git checkout <hash> - NOTE: This will put your repository in a 'detached HEAD' state, which means its currently not attached to any branch - then you'll have some extra work to merge new commits to an actual branch.

Example:

$ git log
commit 89915b4cc0810a9c9e67b3706a2850c58120cf75
Author: Jardel Weyrich <suppressed>
Date:   Wed Aug 18 20:15:01 2010 -0300

    Added a custom extension.

commit 4553c1466c437bdd0b4e7bb35ed238cb5b39d7e7
Author: Jardel Weyrich <suppressed>
Date:   Wed Aug 18 20:13:48 2010 -0300

    Missing constness.

$ git checkout 4553c1466c437bdd0b4e7bb35ed238cb5b39d7e7
Note: moving to '4553c1466c437bdd0b4e7bb35ed238cb5b39d7e7'
which isn't a local branch
If you want to create a new branch from this checkout, you may do so
(now or later) by using -b with the checkout command again. Example:
  git checkout -b <new_branch_name>
HEAD is now at 4553c14... Missing constness.

That way you don't lose any informations, thus you can move to a newer revision when it becomes stable.
