Is Rsyncing git repo good enough backup solution?
提问by DavidW
I often backup my laptop to an external hard drive. Is rsyncing git repos over good enough backup solution or are there any problems with this method?

rsyncis a good solution for this. It may be a good idea to run git gcand git repack(neither with any arguments) before doing your backup; this may significantly reduce the number of files, and increase the chance of the data not changing too much by next time. Neither will lose any data.
rsync是一个很好的解决方案。在进行备份之前运行git gc和git repack（不带任何参数）可能是个好主意；这可能会显着减少文件数量，并增加下次数据不会发生太大变化的机会。两者都不会丢失任何数据。
See http://sethrobertson.github.com/GitBestPractices/#backupsfor a write-up of why doing this with git isn't such a good solution.

rsync is interesting if you really want to backup everything (including hooks and private files).
However:
如果您真的想备份所有内容（包括挂钩和私有文件），rsync 会很有趣。
然而：
- it doesn't guarantee the integrityof your repo once sync'ed (ie is git still working from the rsync'ed repo?)
- it has a higher probability of data corruption(you have to save many many files)
- 一旦同步，它就不能保证你的 repo的完整性（即 git 仍然在 rsync 的 repo 中工作？）
- 它有更高的数据损坏概率（您必须保存许多文件）
A nicer (and cleaner) solution would be to use git bundle(which is essentially a bar repo seen as onefile).
You update your local bundle, and save rsync it to your remote media.
Except that, this time, you only "rsync" (actually a simple copy is enough) one file.
And you can directly clone or pull from that one file, that bundle.
一个更好（更干净）的解决方案是使用git bundle（它本质上是一个被视为一个文件的 bar repo ）。
您更新本地包，并将 rsync 保存到远程媒体。
除此之外，这一次，您只需“rsync”（实际上一个简单的副本就足够了）一个文件。
你可以直接从那个文件中克隆或拉出那个包。

I have a repo I keep on hosting that I push to. If I want to work somewhere I clone it, push changes back when I'm done.
我有一个我继续托管的回购协议。如果我想在克隆它的地方工作，请在完成后将更改推回。
You could rsync it too, but I found it easier to clone a repo out and then use it as my main dev spot. I think using one tool might be easier, but your mileage may vary.
你也可以 rsync 它，但我发现克隆一个 repo 并将其用作我的主要开发点更容易。我认为使用一种工具可能更容易，但您的里程可能会有所不同。
