Data redundancy is key to preventing data loss and achieving fault-tolerance in cloud storage. Cloud storage provider usually charges users according to the requested level of redundancy. However, a cloud provider may fail to offer the committed level of data redundancy intentionally or accidentally, but the users may not be able to detect such breach until data and economic losses have occurred. In this paper, we propose a scheme to allow users remotely assess the actually deployed data redundancy in the cloud storage without knowing the file layout information. Our layout-free scheme establishes response-time profiles for each different file placements, and uses these profiles to evaluate the level of deployed data redundancy. Our experimental results show the feasibility of our scheme on both an in-house cloud and a public cloud. |
