A Comprehensive Study of Different Types of Deduplication Technique in Various Dimensions

Abstract

In the current digital era, the growth of digital data is highly exceptional. There are various sources available for these digital data. The quantity of digital data being produced rose exponentially with time because of organizations and even by individuals, finally end up in the need of huge storage space. Cloud storage provides the storage space for such requirement. Since the storage space is utilized by many different users, having the duplicate data cannot be avoided. So it is necessary to make use of some storage optimization technique to handle such duplicate contents. Deduplication is a technique which is used to evade redundant data get stored. Among the various digital data, the possibility of having duplicate copies is high for data. In this research work, we review the benefits of having deduplication in optimizing the usage of storage space and study about the various types of deduplication techniques in different dimensions which can be used for data. It helps to select the appropriate data deduplication technique to increase their effective storage utilization and reduce the wastage of memory space because of duplicate data.
