Implementation of Cloud Deduplication Mechanism Using Sentence Based Chunking On Hybrid Cloud Architecture

Now a day?s cloud technology are being continuously used in IT field as well as in other to keep the data, cloud re-copying is also a service which has to be focused on. As the cloud service has improved huge focus in last few years. Cloud storage massive management has become important. As the cloud computing services are rapidly being used in recent days for storage and other purposes, cloud deduplication is also such service which has to be focused on. Data deduplication is a technique for reducing the amount of storage space an organization needs to save its data. In most institutes, the storage systems contain duplicate copies of many pieces of data. Deduplication eliminates these extra copies by saving just one copy of the data and replacing the other copies with pointers that lead back to the original copy. For backup and disaster recovery applications, most companies and organizations used deduplication but it can be used to free up space in primary storage as well. To avoid this duplication of data and to maintain the confidentiality in the cloud Hybrid cloud concept is used. For safety and to secure the confidentiality of sensitive data while supporting deduplication, the convergent encryption technique has been proposed to encrypt the data before out sourcing. To better protect data security, this paper makes the first attempt to formally address the problem of authorized data deduplication using content level duplication checking. This paper surveying various works previously done in the area of cloud services and therefore, re-copying of data over cloud storages has still scope of improvement. Inspection on the papers or researches emphasizes various deduplication idea and the ways they are differ from each other for efficient deduplication. Thus as there are many ways of deduplication in clouds, an efficient technique is to be search out having less drawbacks and more outcome.
