To use the AWS Import/Export beta you simply:
* Copy your data to a portable storage device (see below for supported devices).
* Email data loading instructions to AWS in a simple manifest file that includes your Amazon S3 bucket, AWS Access Key ID, and return shipping address. You’ll receive an e-mail back with a unique identifier for the job.
* Securely identify and authenticate the device by digitally signing your manifest file and job identifier with your AWS Secret Access Key and placing that signature file on the device.
* Ship your device along with its interface connectors, power supply and a packing slip to AWS.
When your package arrives at AWS, it will be processed and securely transferred to an AWS data center, where it will be attached to an AWS Import/Export station. Your data load typically begins the next business day after arrival at AWS.
After the data load completes, the device will be detached and returned to you via standard ground shipping.
