In this paper, We assume a primary-backup model with passive replication in combination with point-in-time replication yielding a one-way write to a read-only replica and develop a novel passive asynchronous replication methodology by applying the control approach. This new methodology is an optimization of the Primary-Backup replication service for creating a policy based backup. Finally, Solutions to the optimization problem used in the off-line processing are modeled as a zero-one Knapsack
