Abstract

Nowadays, the demand of data safekeeping capacity is increasing dramatically. Because of more requirements of safekeeping, the computer world is appealing to toward cloud safekeeping. Security of data and cost factors are essential issues in cloud safekeeping. A duplicate document not only waste storage, it also escalates the access time. Therefore, the recognition and removal of duplicate data can be an essential task. Data deduplication, a competent method of data decrease, has gained increasing attention and recognition in large-scale storage space systems. It minimizes redundant data at the data file or subfile level and recognizes duplicated content by its cryptographically secure hash signature. It is very complicated because neither duplicate data do not have a standard key nor they contain mistake. Within this paper, the backdrop and key top features of data deduplication is preserved, then summarize and classify the data deduplication process in line with the key workflow.
