Data grids provide distributed resources for dealing with large scale applications that generate huge volume of data sets. Data replication, a technique much discussed by data grid researchers in past years creates multiple copies of file and stores them in conventional locations to shorten file access times. One of the challenges in data replication is creation of replicas, replica placement and replica selection. Dynamic creation of replicas in a suitable site by data replication strategy can increase the systems performance.
