Your volumes are stored in an Amazon S3 bucket maintained by the AWS Storage Gateway service. Your volumes are accessible for I/O operations through AWS Storage Gateway. You cannot directly access them using Amazon S3 API actions. You can take point-in-time snapshots of gateway volumes that are made available in the form of Amazon EBS snapshots, which can be turned into either Storage Gateway Volumes or EBS Volumes. Use the File Gateway to work with your data natively in S3.
