Mirror a git repository by pulling?
提问by corydoras
I am wondering if there is an easy way, ie like a simple cron job, to regularly pullfrom a remote git repository to a local read only mirror for backup purposes?
我想知道如果有一个简单的方法，即是一个简单的cron作业，定期拉从一个远程git仓库到本地只读用于备份镜像？
Ideally it would pull all branches and tags, but the master/trunk/head would be sufficient.
理想情况下，它会拉出所有分支和标签，但主/主干/头就足够了。
I just need a way to make sure that if the master git server dies, we have a backup location that we could manually fail over to.
我只需要一种方法来确保如果主 git 服务器死机，我们有一个可以手动故障转移到的备份位置。

First create a mirror with
首先创建一个镜像
git clone --mirror [email protected]:repo.git
then setup a cron job like this:
然后像这样设置一个 cron 作业：
*/1 * * * * gitbackup cd /backup/repo.git && git fetch -q --tags
This will backup the changesets every minute. Maybe you want to do this less frequently.
这将每分钟备份一次变更集。也许你想不那么频繁地这样做。

As Andrew noted, every clone of a git repo is a full-fledged backup of the repo. That said, if you want something backed up automatically to a particular machine, you can create a bare repo on the backup server, push into it with all the branches you want backed up in order to initially populate it. Then just setup a post update hook on the "main" repo so that as soon as there are commits pushed in, it goes ahead and pushes them to the backup repo. No need for a cron job or rsync, and its an almost live copy.
正如 Andrew 所指出的，git 存储库的每个克隆都是该存储库的完整备份。也就是说，如果您希望将某些内容自动备份到特定机器上，您可以在备份服务器上创建一个裸仓库，将您想要备份的所有分支推入其中，以便最初填充它。然后只需在“主”存储库上设置一个更新后挂钩，以便一旦有提交推送，它就会继续将它们推送到备份存储库。不需要 cron 作业或 rsync，它几乎是实时副本。

do you have direct access to the server? then you could just rsyncthe .gitdirectory
你可以直接访问服务器吗？然后你可以只rsync在.git目录
