Can I zip a git repo without losing anything?

Can I zip a git repo without losing anything?

[Carl Smith]

Hi all

This is my first post to this list, so thank you for all your work.

After suggesting using zip files to move our projects around, I was
told that you can not zip a git repo without loosing all the history.
This didn't make sense to me, but two people told me the same thing,
so I wasn't sure. I think they may have been confusing the zipped file
you can download from GitHub with a zipped git repo.

If someone could put me straight on this, I'd really appreciate it.

Thanks

Carl

Hi Carl,

The basics of it are as follows, a little simplified to hopefully make it clear

Git uses a working directory that contains the files which you are
working on. These get converted into a snapshot when you commit, and
these commits form the history of your project. These snapshots along
with everything else that git needs to work are stored in the git
directory, often called ".git".

When you zip the files you are working on you are creating a manual
snapshot of your project. If you zip the git directory you are
compressing the entire git repository and this has enough information
to recreate your entire history. If you zip both of them you get your
history as well as any changes that have not been committed yet. When
a server holds a copy of your repository it will not include a working
directory at all, but instead just the git directory. In this
situation the git directory will often be called the same name as the
project.

The zip from GitHub does indeed only contain the working directory,
and so doesn't include the history.

Hope that helps!

To amend the already provided answer -- if you need to move repos
around using the sneakernet, the tool you should probably use is
`git bundle`.
