Data Deduplication on Academic-based Private Cloud

Abstract

Cloud computing provides scalable, low-cost and location-independent services over the internet. The services provided ranges from simple backup services to cloud storage infrastructures. The fast growth of data volumes has greatly increased the demand for techniques for saving disk space and network bandwidth. Cloud storage services choose a deduplication technique where the cloud server stores only a single copy of redundant data and creates links to the copy instead of storing actual copies. The distributed file system plays a very important role in cloud computing environments as well as it is necessary to store and manage data on low cost storage servers in which storage space can be reduced. Today’s businesses are challenged with managing and protecting the ever-increasing amounts of data that is created on a daily and even hourly basis. To counteract this issue, this system proposes a method of multi-tire storage system using data deduplication. The advantage of multi-tire storage system can control and manage service levels to get better storage costs in different types of application environment. Data deduplication technique allows the cloud users to manage their cloud storage space effectively by avoiding storage of repeated data’s and save bandwidth.
