In the Technical world, there is a lot of data increased day by day. These data like text, image, audio, video, etc. These are creating many issues in both the storage and retrieval process. The organization spent the most amount of to cost to retrieve a backup copy. Hence a capable method is to be introduced to handling a large amount of data. Some accessible methods available for removing the repeated data in a backup system are Deduplication and Data Reduction. Data deduplication is the specialized form of data compression technique which eliminates the repeated data, minimize the amount of bandwidth utilization and also maximize the storage space and cost. A mixture of research papers has been collected from the literature study, as the outcome of this paper endeavors to review the techniques of backup storage optimization ideas and methods using deduplication and also the chunking process should be reviewed by this Deduplication Process.

“…Meanwhile, the number of GC processes required in SSD may also increase. Keeping in mind the end goal to utilize the advantage of SSD write-back cache without reducing the SSD lifespan and increasing the number of GC processes excessively, numerous algorithms [39,44,53,74] and architectures [48] are proposed to reduce the number of writes to SSD. In [39], a duplication-aware write handling strategy is used to filter out the duplicated write requests, which saves the number of writes to the SSD device.…”

“…These kinds of NVMs are often utilized as a storage layer or a cache layer in modern hybrid storage systems to improve the performance cost ratio. In the early stage, NVM is deployed as a cache to the HDD devices [39,116,117]. In [117] and [118], the emerging NVM and NAND flash memory are both employed as the cache for HDD to improve the energy efficiency and overall system performance.…”

“…In [39], NVM is added to improve the power management of the disk through four aspects: 1. extending the idle periods, 2. storing the read-miss content in the cache, 3. spinning up the media only when NVM cannot serve the requests and 4. write throttling. In [119], the potential of PCM in a storage hierarchy is evaluated.…”

First of all, I would like to express my great appreciation to my supervisor, Prof. Lihua Xie, for his continuous guidance, encouragement and support throughout my research efforts towards this dissertation. Without his inspiration, deep insight, and invaluable advice, this thesis would not have been possible. I have benefited tremendously from his extensive knowledge, professional experience, and strong commitment towards the excellence of research.
