Simple github backup script

This backup script back ups your personal github repositories via git+ssh including also the private repositories. It uses a combination of a shell script and a PHP script. PHP is used as I only have a very basic set of shell commands available at my webhoster "Netcup". So this script also works on cheap webhosting packages.

Requirements

• curl
• git
• PHP (5.x should be enough)
• tar
• gzip

Usage

• Create a personal access token in your GitHub Settings->Developer Settings with read:packages scope
• Run the script via cronjob like so: GITHUB_AUTH_TOKEN=<YOUR TOKEN> cd github_backup && ./backup.sh > log.log 2>&1

Result

The script will mirror all your repositories to a local temporary directory and finally tgz it.

Attention the script contains a line to remove all existing .tgz files first, as I only wanted one backup. As the filename contains the date you could remove this line and have one backup per day. But you will want to implement a cleanup as each backup contains a full copy of all repos.
