Development of Distributed Backup System among Individuals by Introducing Deduplication

Recently, as a robust backup, geographically dispersed and distributed backup systems to save data have been attracting attention. However, existing distributed backup systems that can be operated at low cost present various difficulties such as processing time, immediacy, and storage capacity. Therefore, as an existing method intended to solve this problem, multiagentbased distributed backup systems exist for individuals to solve problems of processing time and immediacy. However, problems of storage capacity exist in such systems. This research presents a deduplication technique of block data to solve problems of storage capacity. By incorporating this into the system, we aim at storage capacity reduction of backup data.
