Abstract	As large amount of data that is produced by scientific experiments and simulations, data grid is a very important and useful technique to solve these kinds of problems in this region. Data replication is one technique that many researchers discuss in past years in data grid. It can create many copies of file and stored in the appropriate location to shorten the time of getting the file. In this paper, we propose a dynamical maintenance service of replication to maintain the data in grid environment. Replicas will be adjusted to the appropriate location for using. The BHR algorithm is a strategy to maintain replica dynamically. We point out a scenario that the BHR algorithm will cause a mistake when it operates. That mistake will limit the speed of transferring file. We propose the Dynamic Maintenance Service is aimed at overcoming the mistake proposed. The contributions of this paper are that the data grid environment will be more efficiency by using DMS algorithm. And the experimental results show that the DMS algorithm is more efficient than other replication strategies.
