Deduplication Schemes for Cloud Backup

It is observed that increasing use of cloud storage environment for data backup is increasing the challenge of performing Deduplication due to combination of resource intensive nature of the deduplication and limitation of the system resources. In this paper, a review of different Deduplication schemes such as ALG, SAM and AA-Dedupe is done. By this an attempt has been made to find good balance between cloud storage capacity saving and deduplication time reduction. This paper studies the deduplication techniques that follows fingerprinting based approach.
