"Versioning allows you to preserve, retrieve, and restore every version of every object stored in an Amazon S3 bucket. Once enabled for a bucket, Amazon S3 preserves existing objects anytime you perform a PUT, POST, COPY, or DELETE operation on them. By default, GET requests will retrieve the most recently written version. Older versions of an overwritten or deleted object can be retrieved by specifying a version in the request."
