Is it necessary to backup S3?
jacquesm: How would you feel if one day that data was lost ?There are already documented cases of Amazon losing data in S3.The Amazon S3 SLA does not cover data loss at all, only service unavailable situations, which they will cover by crediting you.http://aws.amazon.com/s3-sla/http://www.datacenterknowledge.com/archives/2007/10/09/amazo...And even if all this was not the case you have a responsibility to your customers you can not outsource that responsibility.
