Backup and restore a git repo using git bundle

Backup&RestoreRepo.md

Backup/archive a repo

1. Clone the repo

git clone --mirror https://github.com/vuejs/vue

2. cd into the cloned repo
3. Create a bundle file in the parent directory

git bundle create ../vuejs_vue.bundle --all

4. That bundle file is now a full archive of the repo, including all of its branches and tags

Restore a repo from a bundle file

Here we will restore the repo from the bundle and create a new remote origin that will contain all brnaches and tags

1. Clone the repo from the bundle

git clone vuejs_vue.bundle

2. Get all the branches locally to be pushed up to your origin later (from: https://gist.github.com/grimzy/a1d3aae40412634df29cf86bb74a6f72)

git branch -r | grep -v '\->' | while read remote; do git branch --track "${remote#origin/}" "$remote"; done
git fetch --all
git pull --all

3. Create a new repo on your git server and update the origin of the local repo

git remote set-url origin [email protected]/xtream1101/test-backup.git

4. Push all branches and tags to the new remote origin

git push --all
git push --tags

@keyserjaya This reply is pretty late (I just came across this script), but this is a bash (shell) script meant to be run in a Linux shell. If you have WSL2 installed, you can likely use the command line in a virtual instance of Linux to run the script, but it will not be supported by Windows PowerShell.

If you have git for Windows installed, you likely have a Bash terminal (shortcut in the Start Menu) which can run some Shell scripts but Bash on Windows does not support things like grep commands out-of-the-box. (There may be third-party Windows tools that simulate the program's functionality -- see wget for example -- but not that I know of for grep in particular.
