We’ll discuss two cases:

Taking a full backup of a repository

Transferring the history of a repository to another machine when the two machines have no direct connection

Exemple de creation de Bundle Git

git bundle create mybundle v1.0.0..master
git bundle create mybundle --since=10.days master
 
git bundle create mybundle --all

Note that --all would not include remote-tracking branches… just like ordinary clone wouldn't either. First clone the repository, and include the --mirror option.

git clone --mirror git@example.org:path/repo.git

Then run

cd /opt/plop
git bundle create repo.bundle --all
git tag -f lastAGbundle master
 
$ cd cd /opt/plop
$ git bundle create ~/toAG/RepoName.bundle lastAGbundle..master --all
$ git tag -f lastAGbundle master
 
$ cd /path/to/AG/clone/location
$ git clone /path/to/AG/bundles/RepoName.bundle -b master
$ cd RepoName
$ git gc # Clears some errors 
$ # Optionally, push to other remotes
 
git bundle verify mybundle

Exemple d'importation de Bundle

[remote "origin"]
    url = /home/me/tmp/file.bundle
    fetch = refs/heads/*:refs/remotes/origin/*

machineB$ cd R2
machineB$ git pull

$ git bundle list-heads ../commits.bundle
71b84daaf49abed142a373b6e5c59a22dc6560dc refs/heads/master

$ git fetch ../commits.bundle master:other-master
From ../commits.bundle
 * [new branch]      master     -> other-master

git clone --bundle-uri=https://[cdn]/bundle/gitlab-base.bundle 
git clone --bundle-uri=https://[cdn]/bundle/gitlab-base.bundle https://gitlab.com/gitlab-org/gitlab-foss.git g2
