git - 备份使用 git 的项目

Question

在快速重新安装之前，我正在将我的东西刻录到 DVD 上。作为最近的用户，从来没有用 git 做过。所以我只是和你们核实一下。如果我理解正确的话，我只需要备份我的项目目录 project_name(里面有 .git)，看是否有 stash 文件，当我把它复制到"new"机器上时，再次安装 git，我像什么都没发生一样恢复？正确吗？

Answer 1

如果你只想备份项目文件(没有历史)，你可以使用git archive (这样，我就不必“监视 stash 文件”)

脚本git-archive-all.sh实际上会归档当前路径中的所有 git 存储库和子模块。

Useful for creating a single tarfile of a git super-project that contains other submodules.

作为Charles Bailey在评论中正确提到， git bundle 更合适，保留历史。 (git bundle 在 February 2007 中引入)。

参见 Backing up a git repository with git bundle

git bundle was designed to allow transfer of git commits when there is no direct connection between repositories (i.e.: offline) but using patches is not an option because of the large number of commits and multiple branches.
A git bundle is just one file which can be very easily created and again imported as it can be treated like another remote. A quick example:

jojo@dualtron:~/devel$ git bundle create ~/devel.bdl master test 

and a bundle is saved under ~/devel.bdl containing my master and test branches.
If I am now at repository B I just use jojo@dualtron:~$ git ls-remote devel.bdl which shows me the branches stored in the bundle.
To use the bundle I simple treat it like a remote, using git fetch (for example)

jojo@dualtron:~/git/repoB$ git fetch ~/devel.bdl refs/heads/\*:refs/remotes/bundle/\*
