(English Abstract)
The implementation approaches of data deduplication backup system divide into several modes including SBA (source-based approach), ILA (in-line approach) and PPA (post-process approach). Currently, most commercial systems are implemented and operated in an ILA and PPA approach, and some researchers have focused on the SBA approach. As data deduplication systems are widely used, to choose an appropriate mode considering operation environment becomes more and more important than ever. Because the overhead of each mode and resource usage was not fully studied, in some operating environments, use of system resources can lead to inefficiency and poor performance. In this study, we propose a data deduplication system supporting multi-mode. The proposed system can be operated in a mode that a user specifies, therefore, this system can be used in various environments. In this paper, we operate the proposed system with the SBA, ILA, and PPA mode, respectively, and we present the measurement results with a comparative analysis of the mode-specific performance and overhead.
