Reduced Redundancy Storage (RRS) is an Amazon S3 storage option that enables customers to reduce their costs by storing non critical, reproducible data at lower levels of redundancy than Amazon S3’s standard storage. It provides a cost-effective, highly available solution for distributing or sharing content that is durably stored elsewhere, or for storing thumbnails, transcoded media, or other processed data that can be easily reproduced. The RRS option stores objects on multiple devices across multiple facilities, providing 400 times the durability of a typical disk drive, but does not replicate objects as many times as standard Amazon S3 storage.
Reduced Redundancy Storage is:
Backed with the Amazon S3 Service Level Agreement for availability.
Designed to provide 99.99% durability and 99.99% availability of objects over a given year. This durability level corresponds to an average annual expected loss of 0.01% of objects.
Designed to sustain the loss of data in a single facility.
