In order to save the computer data effectively, we should not only check the integrity for the data integrity, but also check storage system to recover data in a timely manner to reduce losses to a minimum, to prevent the recover fails when the fault occurred. The viability and integrity of the system to recover the data is determined by the recovery algorithm, so the key to recover the data is how to design the recovery algorithm. This paper presented an advanced recovery techniques based on the traditional recover algorithm which based on the log, then the specific data structure and algorithm implementation is given at the last of this paper.
