Abstract :
Data recovery on Erasure code could effectively improve the reliability of data storage; however, the algorithm also increased time of data recovery. On the basis of that, this paper presents distributed data recovery based on grid service (DDR-GS), which combines with grid services to improve the efficiency of data recovery. Through extensive experiments on random datasets, it is shown that with the increasing of the number of nodes, DDR-GS improves the speed of matrix calculation. And the time of data recovery is greatly reduced about 77.74%.
