SSR-CDPS: A Novel Continuous Data Protection System Supporting Service Recovery

Abstract:

With the rapid development of computer networks, invasion and attack becomes more and more frequent in network environment. Therefore, insuring the information system continuously and correctly working has become an urgent problem in the information security field. And continuous data protection (CDP) supporting service recovery provides us a good idea to resolve it. In this article, we have designed and implemented a continuous data protection system supporting service recovery, which is named SSR-CDPS. The basic design idea of the SSR-CDPS architecture is dividing the whole protection process into three stages: monitoring, protecting and recovery. Meanwhile, we propose a multi versioning data backup mechanism for the protecting process and a novel file failure recovery mechanism. Especially, we transfer the full copy operation of file contents into the merely slight modification operation on the FAT table, MFT table or other similar data structures; so that we achieve the aim of greatly reducing the direct disks read and write overhead. The test toward the SSR-CDPS prototype system shows that the system can significantly improve the efficiency of data protection within limited change to the existing file system; thus, it can meet the high real-time and the continuity requirements of the information system recovery applications.
