如何将Git仓库备份到本地

$ mkdir git-backup #创建一个备份文件夹
$ cd git-backup #切换到文件夹下
$ git clone --bare /Users/xxx/Documents/WorkSpace/GitTest/LocalTest/.git ya.git #使用哑协议 克隆一个不带工作区的仓库
Cloning into bare repository 'ya.git'...
done.
$ ls
ya.git
$ git clone --bare file:///Users/xxx/Documents/WorkSpace/GitTest/LocalTest/.git zhineng.git #使用智能协议 克隆一个不带工作区的仓库（智能协议传输不仅有打包，还有压缩，所以传输速度快）
Cloning into bare repository 'zhineng.git'...

fatal: The current branch remote_test has no upstream branch.
To push the current branch and set the remote as upstream, use

    git push --set-upstream zhineng remote_test
$ git push --set-upstream zhineng remote_test #意味着下次push’remote_test‘分支到’zhineng‘分支就不用再设置
