摘要:
There is provided a method and system for replicating data at another location. The system includes a source node that contains data in a data storage area. The source node is coupled to a network of potential replication nodes. The processor determines at least two eligible nodes in the network of nodes and determines the communication cost associated with a each of the eligible nodes. The processor also determines a probability of a concurrent failure of the source node and each of eligible nodes, and selects at least one of the eligible nodes for replication of the data located on the source node. The selection is based on an the determined communication costs and probability of concurrent failure.
