Amazon S3 is excited to announce Multipart Upload which allows faster, more flexible uploads into Amazon S3. Multipart Upload allows you to upload a single object as a set of parts. After all parts of your object are uploaded, Amazon S3 then presents the data as a single object. With this feature you can create parallel uploads, pause and resume an object upload, and begin uploads before you know the total object size. For more information on Multipart Upload, review the Amazon S3 Developer Guide or attend the Amazon S3 Multipart Upload webcast on November 17.
