• Implementation of prototype for reliability
aware algorithm for deduplicated cloud storage
• Implementation of prototype for Reed-
Solomon algorithm for deduplicated cloud
• Experimental evaluation of redundancy
schemes and choosing the optimised
redundancy scheme for cloud storage system.
Reliable Aware Deduplicated Storage
System (RADS) Design
• In order to implement the objectives, we are
implementing RADS which consists of :-
• Modules :-
1. Cloud Storage system
2. Reliability Aware Algorithm
3. Reed Solomon Algorithm
4. Performance measures
