Depreciated: Heroku depreciated their Bundle backup system in favor of the new PG Backups, you can find a modified version of this script in another gist.

Heroku is awesome! The easiest way to backup you application on Heroku is to pay $20 per month and have unlimited backups (or bundles as they call it).

The cheaper way is to create the backup on the fly (you get one bundle for free) and download it to a local storage somewhere. This is my preferred solution as it is cheaper and it makes sure you have a local copy of your application if Heroku would fail for some reason.

The script above removes the previous local backup if the new one is successful. You could improve this and have more local backups if needed but this script covers my basic needs.

You'll need to have your Heroku credentials in ~/.heroku/credentials and activate the Bundles add-on for this to work (and the Heroku gem as well, but that's kinda obvious... not?).
