What is the Reduced Redundancy option in Amazon S3?
A.
Less redundancy for a lower cost.
B.
It doesn’t exist in Amazon S3, but in Amazon EBS.
C.

A.
In order to reduce storage costs, you can use reduced redundancy storage for noncritical, reproducible data at lower levels of redundancy than Amazon S3 provides with standard storage. The lower level of redundancy results in less durability and availability, but in many cases, the lower costs can make reduced redundancy storage an acceptable storage solution.
