The Advanced Data Recovery Technology Based on the Log Recovery

In order to effectively preserve the hard disk data, we should not only regularly back up, but also need to recover data when your hard disk failures, in order to reduce the losses minimized. The key for database recovery is how to design the restoration algorithm, how to design a restoration algorithm will determine the feasibility of the database data recovery and restoration of data integrity. According to the traditional log-based recovery this paper proposed an advanced recovery techniques, and then we had given the specific data structure and algorithm implementation process for the advanced recovery algorithm.
