Data replication is a practical and effective method to achieve efficient and fault-tolerant data
access in grids. Traditionally, data replication schemes maintain an entire replica in each
site where a file is replicated, providing a read-only model. These solutions require huge
storage resources to store the whole set of replicas and do not allow efficient data
modification to avoid the consistency problem. In this paper we propose a new replication
method, called the Branch Replication Scheme (BRS), that provides three main advantages …
