Abstract

Entire world is adapting digital technolo- gies, converting from legacy approach to Digital approach. Data is the primary thing which is available in digital form everywhere. To store this massive data, the storage methodology should be efficient as well as intelligent enough to find the redundant data to save. Data de-duplication techniques are widely used by storage servers to eliminate the possibilities of storing multiple copies of the data. De-duplication identifies duplicate data portions going to be stored in storage systems also removes duplication in existing stored data in storage systems. Hence yield a significant cost saving. In this paper, we, investigate about data de-duplication its techniques and changes introduced in de-duplication due to virtualized data centre and evolution of current cloud computing era.
