How to back up private branches in git

Question

I have a local branch for day-to-day dev work in git. My workflow is:

1. Do stuff on local_branch, commit
2. Fetch origin/master
3. Rebase local_bran

Answer 1

Rather than relying on Dropbox to synchronize all the files of a git repo, I would rather use git bundle, which produces only one file (including all your private branches), and sync that file with DropBox.
See "Git with Dropbox"

In "Backup a Local Git Repository", Yars mentioned having sync errors with Dropbox.
