Complete git repository backup script to Backblaze B2

# Script to backup git repo to Backblaze B2
# Set bucket, dir, password and account to use for the backup. I keep mine in local env vars
# These are set by localrc which lives on an encrypted home directory and is executed by my bashrc
# Ensure you have authorized the B2 command line tool with the correct account AND added your SSH
# public key to your github account, if you need to backup private repositories.
# To restore this repo in the future, download it from B2, extract it and then use this command:
# cd old-repository.git
