Perlustration on techno level classification of deduplication techniques in cloud for big data storage

In the bygone, the exploration in computing focused on cloud computing, big data, and the internet of things (IOT). Irrespective of what computing is used, there is always a requirement for storage. The challenge faced in this area is storing the massive amount of data and their integrity. In the cloud, computing resources and services are made available on demand the most significant among them is their data storage. In this article, the focus is on the literature by providing an edifice and comprehensive overview of different de-duplication techniques that are used in distributed storage. Deduplication (de-dupe) technique is progressively accepted as an effective technique to reduce the cost of storage, where the de-dupe has become a vital part of the storage infrastructure. This paper also reviews the context and key features of data de-dupe and systematize the technetronic research in data de-duplication rendering the dynamic process flow. The summary and cataloguing of the high-tech on deduplication help to improvise the furthermost design considerations for data deduplication techniques. Finally, we summarize the open problems and future exploration area in a deduplication based on storage systems.
