Abstract

Data deduplication is widely used to reduce storage space requirement in cloud storage system. Especially chunking based deduplication scheme is very useful for handling data storage system that contains duplicated blocks of file stream. In this paper, we introduce a novel data deduplication scheme that manages metadata of cloud storage system in a rapid time. The key points of this paper are using tree map searching and classifying data as global and local metadata. The two-level metadata management scheme is the main aspects to influencing fast performance of the data deduplication.
