A ruby script used to maintain an offsite backup of git repositories.
Clone your repositories to be backed up into a single directory on some server:
mkdir /home/myuser/mybackups
cd /home/myuser/mybackups
git clone user@server:repo1
git clone user@server:repo2
Modify baseDir to match the full path to the directory you used in step 1
Run ./backup.rb
Add it to cron via crontab -e for scheduled backups
