rsync .git 目录

Question

This question probably is based on my lack of understanding of the role of .gits and git repositories in general but:

Can I rsync a dir with content that I created with git init between machines ?

I have a repository on my laptop, and the only way to get it away from there is scp/rsync to a remote host, from which I can download it again. Could I rsync the complete directory structure between these hosts?

Answer 1

There are a few possibilities:

• You can just rsync the .git repository (or even whole repository together with working directory), provided that you don't have any activity in repository during rsync ing (same disclaimer as for using rsync:// protocol).

• You can clone or fetch using deprecated rsync protocol (where repository URL / location looks like this: " rsync://host.xz/path/to/repo.git/ "). Note that this protocol is deprecated, because if there is any activity in repository, you can get corrupted clone (or fetch).

  Also, as I have heard, it didn't work correctly in the presence of packed refs since 2007, and nobody noticed till recently. It will (it did) disappear in Git 2.8.

• Or you can create git bundle , rsync it or scp it on other machine, and then clone or fetch from bundle.

Answer 2

Yes, that is possible. IIRC, git uses a relative approach. So it's safe to sync it with another computer.

Answer 3

Yes you can, but you should do so with a bare repository, as illustrated in this 2012 article :

$ git clone --bare ./projet projet.git
$ rsync -a --stats --delete ./projet.git/ votre.serveur:~/projets/projet.git/

Note: 6+ years later, git 2.8 (March 2016) will officially deprecate and fully remove the git rsync protocol !

See commit 0d0bac6 (30 Jan 2016) by Jeff King ( peff ) .
^{(Merged by Junio C Hamano -- gitster -- in commit 9f03176 , 17 Feb 2016)}

It turns out " git clone " over rsync transport has been broken when the source repository has packed references for a long time, and nobody noticed nor complained about it.

Commit 0d0bac6 from Jeff King ( peff ) has all the details.

Answer 4

You can rsync without any problems, but if you have some remotes declared with hostnames which are local to the machine (ie stored in /etc/hosts only) then those obviously won't work.

However, is there some reason why you don't use git itself to sync the content?

Answer 5

是的， rsync对.git目录是可能的，这将导致存储库的完整克隆。

Answer 6

Using rsync to backup .git is possible, but with one catch ( at least to myself) It can not be updated. The next time you try to rsync it again, you got massive object rename.. and you can not delete those.. Been not familiar with rsync or linux system, I purge the .git backup before I rsync it.

Which is:

> chmod -R 777 /path/of/your/backup/.git
> rm -fr /path/of/your/backup/.git
> rsync /path/of/your/origin/.git /path/of/your/backup/.git

I know, this is very taxing and stupid.. Please let me know is there a better way to do this..
