Data de-duplication is widely used to reduce storage space requirement in cloud storage system. Especially chunking based de-duplication scheme is very useful for handling data storage system that contains duplicated blocks of file stream. In this paper, the authors introduce a novel data de-duplication 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.
