Information Technology Disaster Recovery Plans (DRPs) are becoming an essential component for any organization with IT infrastructure. However, DRPs varies in performance and cost; therefore, based on requirements and resources, an organization can design their DRP. Typically, DRPs depends on data and/or system replication, data needs to be backed up frequently, and a plan to restore the system to running state within the allowed time. Hence, DRP designer must know the needed business requirements in terms of recovery time objective (RTO) and recovery point objective (RPO). Then, the appropriate technical requirements will be set. At the same time, the cost factor can play a role in choosing the appropriate DRP. The industry has a widely accepted seven-tier system of how DRP can be designed. In this work, we design and implement a software tool that can simulate the IT DPR systems and therefore help designers to design, optimize, and test their design before it is physically implemented. This tool will run a simulated system with DRP specific design and the designer can exercise with the system to show it’s RTO, RPO, and cost that can significantly improve DRP design.
