Paper Abstract

Data is the core resource of the information system, so that data corruption is one of the key problems which are on top of the radar screen of most information system administrators. Continuous Data Protection (CDP) technologies help them deal with data corruption by providing timely recovery to any point-in-time. But in this CDP process, the CDP system needs record every data changes, and then the extra system I/O operations increase greatly, the performance of information systems will be lower and the system cannot provide the best service. This paper discusses a method based buffer chains that can reduce the extra I/O operations from the disk. We have presented an implementation in the Linux kernel which provides continuous data protection service with higher performance under some buffer chains strategy.
