Automate Heroku Backup

# First, you need a bundle captured if you haven't already.
heroku bundles:capture

# Second, you need to destroy the old one to create a new one.
# Then you can download the backup.
heroku bundles:destroy `heroku bundles | awk '{print $1}'`
heroku bundles:capture
# give it 1 minute to create the file
sleep 60
heroku bundles:download

# Here is a more complex example grabbing the app name.
heroku info | grep '===' | awk '{print $2}'

# You can then pass it into the bundles command
heroku bundles:destroy --app `heroku info | grep '===' | awk '{print $2}'` `heroku bundles | awk '{print $1}'`
heroku bundles:capture --app `heroku info | grep '===' | awk '{print $2}'` 
# give it 1 minute to create the file
sleep 60
heroku bundles:download --app `heroku info | grep '===' | awk '{print $2}'`

# You can also use it to move the file outside your git repo and 
# rename the backup file to the bundle date.
mv `heroku info | grep '===' | awk '{print $2}'`.tar.gz /path/to/backup/
