Explanation: In Amazon S3, RRS stands for Reduced Redundancy Storage. Reduced redundancy storage stores objects on multiple devices across multiple facilities, providing 400 times the durability of a typical disk drive, but it does not replicate objects as many times as Amazon S3 standard storage. In addi-tion, reduced redundancy storage is designed to sustain the loss of data in a single facility. Reference: http://docs.aws.amazon.com/AmazonS3/latest/dev/UsingRRS.html
