Abstract

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.

引入重复数据删除技术开发分布式个人备份系统
近年来,作为一种鲁棒性备份,地理上分散和分布式的数据存储备份系统一直受到人们的关注。然而,现有的低成本分布式备份系统在处理时间、即时性和存储容量等方面存在诸多困难。因此,基于多agent的分布式备份系统作为解决这一问题的现有方法,为个人解决处理时间和即时性问题而存在。但是,这种系统存在存储容量问题。本研究提出一种基于块数据的重复数据删除技术,以解决存储容量问题。通过将其整合到系统中,我们的目标是减少备份数据的存储容量。
