A Survey on Deduplication Techniques for Storage Optimization

Abstract

In the Technical world, there is a lot of data increased day by day. These data like text, image, audio, video, etc. These are creating many issues in both the storage and retrieval process. The organization spent the most amount of to cost to retrieve a backup copy. Hence a capable method is to be introduced to handling a large amount of data. Some accessible methods available for removing the repeated data in a backup system are Deduplication and Data Reduction. Data deduplication is the specialized form of data compression technique which eliminates the repeated data, minimize the amount of bandwidth utilization and also maximize the storage space and cost. A mixture of research papers has been collected from the literature study, as the outcome of this paper endeavors to review the techniques of backup storage optimization ideas and methods using deduplication and also the chunking process should be reviewed by this Deduplication Process.
