Cloud Storage provide users with abundant storage space and make user friendly for immediate data access.But there is a lack of analysis on optimizing cloud storage for effective data access.With the development of storage and technology, digital data has occupied more and more space.According to statistics, 60% of digital data is redundant, and the data compression can only eliminate intra-file redundancy.In order to solve these problems, De-Duplication has been proposed.Many organizations have set up private cloud storage with their unused resources for resource utilization.Since private cloud storage has limited amount of hardware resources, they need to optimally utilize the space to hold maximum data.In this paper, we discuss the flaws in existing methods for Data De-Duplication.Our proposed method namely Dynamic Whole File De-duplication (DWFD) provides dynamic space optimization in private cloud storage backup as well as increase the throughput and de-duplication efficiency.
