Improve Fault Tolerance and Dependable Data Integrity Protection of Storage System in Cloud of Clouds

To protect outsourced data in multiple cloud storage environment, we provide fault tolerance and dependable data integrity for cloud storage. Suppose if cloud storage experiences the permanent failure and loses all its data then, there is a need to regenerate the lost outsource data with help of other surviving cloud storages. We propose a Proxy based Storage for fault tolerant multiple cloud storage environment called as Network coding based storage. Functional minimum-storage regenerating (FMSR) codes are used for regenerating lost outsourced data in multiple cloud storage environment. We also validate that FMSR codes reduce repair traffic and incur less monetary cost during data transfer than traditional erasure (RAID-6).
