Say Github gets DDoS’d out of existence and all my hard drives simultaneously ignite; I’ll bet I’d wish I had that third copy of my code to carry with me into the apocalypse! You can use git bundle --all to package a full repo into one file.

I made a bash script and git aliased it, to take most of the hand-cramp out of the method.

1 #!/bin/sh
2 DEST=~/Dropbox/Git\ Backups/
3 REPO=$(basename "`git rev-parse --show-toplevel`")
5 (git bundle create "${DEST}${REPO}.bundle" --all)
git config --global alias.bundled '!sh /where/script/is/'

This way, git bundled makes a new repo_name.bundle appear in my Dropbox folder where it’s then spirited off to the cloud. I’ll do this at the end of the day, with any work I’ve done, or even just after a push. You can compare refs for a bundle with git bundle verify repo_name.bundle to a regular repo’s git show-ref.

Once a bundle’s been synced to another computer, emailed, or pulled off a thumb drive, it can be cloned or pulled from as if it were a remote.
