Data deduplication avoids redundant data in the storage of backup operation. Deduplication reduces storage space and overall amount of time. In this system, files that contain data are split into chunks by using context aware chunking and fingerprints lookup to each chunk. Backup storage process is for avoiding duplicate data using fingerprints lookup. In this paper, the authors compare three methodology of backup systems such as full backup, cumulative incremental backup and differential incremental backup.
