There seems to be a lot of differing opinions out there on how best to handle git + dropbox.
My solution, is to keep it simple. Store git bundles in dropbox.
Further, I’ve added a hook for post-commit to dump the bundle right into dropbox. This way, I a) force myself to commit more because I can’t lazily rely on dropbox syncing all saved files and b) assure that my files–nay, the whole repository!–is backed up into the cloud.
.git/hooks/post-commit file looks like this:
git bundle create ~/Dropbox/GitBundles/BeerProject.git.bundle master
And that’s what I call, The Easy Way.
