“…In static replication, all decisions regarding the replication strategy are made before the system is operational and not changed during operation [13,18,22,32]. On the other hand, in dynamic replication, what, when, and where to replicate are decided as a response to the changing trends of the data grid [11,41,42,54].…”

“…fault-tolerance, security, load balancing points of view. However, from the most general perspective, data replication strategies can be divided into two categories, namely static [13,18,22,32] and dynamic [11,41,42,54] replication. In this paper, we are focusing on dynamic replication strategies, where all replication decisions are made adaptively while the system is in operation.…”

In data grid systems, data replication aims to increase availability, fault tolerance, load balancing and scalability while reducing bandwidth consumption, and job execution time. Several classification schemes for data replication were proposed in the literature, (i) static vs. dynamic, (ii) centralized vs. decentralized, (iii) push vs. pull, and (iv) objective function based. Dynamic data replication is a form of data replication that is performed with respect to the changing conditions of the grid environment. In this paper, we present a survey of recent dynamic data replication strategies. We study and classify these strategies by taking the target data grid architecture as the sole classifier. We discuss the key points of the studied strategies and provide feature comparison of them according to important metrics. Furthermore, the impact of data grid architecture on dynamic replication performance is investigated in a simulation study. Finally, some important issues and open research problems in the area are pointed out. B Uras Tos
