This document describes a study comparing redundancy schemes for deduplicated cloud storage systems. It discusses implementing prototypes for a reliability-aware algorithm and Reed-Solomon algorithm for cloud storage. The Reliable Aware Deduplicated Storage System (RADS) is designed with modules for the cloud storage system, reliability algorithm, Reed-Solomon algorithm, and performance measures. Results are presented along with references. The goal is to experimentally evaluate the redundancy schemes and identify the optimized approach for cloud storage reliability.
