Compression and Replication of Device Files using Deduplication Technique {tag} {/tag} International Journal of Computer Applications © 2012 by IJCA Journal Volume 45 - Number 1 Year of Publication: 2012 Authors: Bharati Siddhant Agarwal Abhishek Somani Rukmi Patel Ankita Shingvi 10.5120/6744-8847 {bibtex}pxc3878847.bib{/bibtex} Abstract One of the biggest challenges to the data storage community is how to effectively store data without taking the exact same data and storing again and again in different locations on the back end servers. In this paper, we outline the performance achievements that can be achieved by exploiting block level data deduplication in File Systems. We have achieved replication of data by storing a deduplicated copy of the original data on the backup partition, which can enable us to access or restore data in case of a system crash.
