Recovery strategies of a Disaster Recovery planning (DRP) must be aligned with the cost/benefit analysis and business objectives. A DRP is a part of a BCP/DRP that focuses on restoring the normal operation of the organization's IT systems and infrastructure after a disruption or disaster.
A DRP should include various components, such as:
Risk assessment: a process that identifies and evaluates the potential threats and vulnerabilities that might affect the IT systems and infrastructure, and estimates the likelihood and impact of a disruption or disaster Recovery objectives: a process that defines and quantifies the acceptable levels of recovery for the IT systems and infrastructure, such as the recovery point objective (RPO), which is the maximum amount of data loss that can be tolerated, and the recovery time objective (RTO), which is the maximum amount of downtime that can be tolerated Recovery strategies: a process that selects and implements the appropriate methods and resources to recover the IT systems and infrastructure, such as backup, replication, redundancy, or failover DRP document: a document that outlines and details the scope, purpose, and features of the DRP, such as the roles and responsibilities, the recovery procedures, and the contact information Testing, training, and exercises: a process that evaluates and validates the effectiveness and readiness of the DRP, and educates and trains the relevant stakeholders, such as the IT staff, the management, and the users, on the DRP and their roles and responsibilities Maintenance and review: a process that monitors and updates the DRP, and addresses any changes or issues that might affect the DRP, such as the IT requirements, the threat landscape, or the feedback and lessons learned Recovery strategies of a DRP must be aligned with the cost/benefit analysis and business objectives, because it can ensure that the DRP is feasible and suitable, and that it can achieve the desired outcomes and objectives in a cost-effective and efficient manner. A cost/benefit analysis is a technique that compares the costs and benefits of different recovery strategies, and determines the optimal one that provides the best value for money. A business objective is a goal or a target that the organization wants to achieve through its IT systems and infrastructure, such as increasing the productivity, profitability, or customer satisfaction. A recovery strategy that is aligned with the cost/benefit analysis and business objectives can help to:
Optimize the use and allocation of the IT resources and funds for the recovery Minimize the negative impacts and risks of a disruption or disaster on the IT systems and infrastructure Maximize the positive outcomes and benefits of the recovery for the IT systems and infrastructure Support and enable the achievement of the organizational goals and targets through the IT systems and infrastructure
