By only doing clones to get data from Github, you're losing anything stored in LFS. Run `git lfs fetch --all` inside each repo after cloning to make sure you have the large files, too.

I made (refined an existing one I found in a gist) a little script recently that does this more efficiently with bare repos and bundles: https://github.com/JarvusInnovations/fed-git-backups

USDS, 4.2GB, 54 repos:

    gh repo list usds --limit 9999 --json sshUrl | jq -r '.[].sshUrl' | xargs -n1 git clone

18F, 37GB, 1,213 repos:

    gh repo list 18F --limit 9999 --json sshUrl | jq -r '.[].sshUrl' | xargs -n1 git clone

I'm worries git lfs will be too large.
