Performance Comparison of Deduplication techniques for storage in Cloud computing Environment

Abstract

Cloud computing is a new technique to add functionality to a computer without licensing new software, investing in new hardware or infrastructure. Applications are purchased, licensed and run over the network instead of users desktop. It provides common business applications online that are accessed from a web browser, while the software and data are stored on the servers. Private Cloud storage can be built from the unused resources to store the data that belongs to an organization. Many organizations have set up private Clouds as they results in better utilization of resources. Since private Cloud storage have limited amount of hardware resources they need to be utilized optimally so has to accommodate maximum data

Deduplication is an effective technique to optimize the utilization of storage space. The work in this paper focuses on deduplication. Two methods adopted for deduplication, namely, chunk level and file level, are studied here. This paper discusses the implementation of both these methods in Cloud storage and results are analyzed.
