AWS Import/Export allows you to ship your data on one or more portable storage devices to be loaded into Amazon S3. For each portable storage device to be loaded, a manifest explains how and where to load the data, and how to map file to Amazon S3 object keys. After loading the data into Amazon S3, AWS Import/Export stores the resulting keys and MD5 Checksums in log files such that you can check whether the transfer was successful.
Amazon continues to amaze me with their focus on simply doing the right thing. Impressive.
