There are many solutions to move data (backup, replicate, and synchronize) between your on premise environment and AWS S3. However, when you are looking for a solution that can backup your AWS EBS volumes to S3 there are not as many. There are some vendor specific products (i.e. Oracle Secure Backup) but nothing that natively (at a file system or raw partition level) backups up EBS to S3. Such a solution, would also have the added value of using the same tool / product to back up on premise disk and EBS volumes using the same method. One company that offers such a solution is Ctera (http://www.ctera.com).
