Step 1, make a container named "export" under Storage > Files inside the rackspace cloud control panel.
Step 2, customize this script and run it on any unix machine OR read the docs below it to see other methods.

1) Exporting the image to Cloud Files
You can export the image from Rackspace to your Cloud Files containers using the API. The article below can guide you through that process.

There is also a tool you can use called ‘Pitchfork’. Once you log into Pitchfork using your username and API key, you would navigate to the ‘Images’ section and choose ‘Export’. Once you run that API call, some time will pass before you see the image in one or multiple Cloud Files containers.

2) Downloading image from Cloud Files
You can use Swiftly to download the image from Cloud Files. An object in Cloud files cannot be greater than 5GB. If your image is greater than this, it will be divided into multiple Cloud files objects, which can be downloaded and reassembled locally using Swiftly.
