The cost of putting a disaster recovery plan into action can vary based on the size, complexity, and needs of the organisation. The cost can include expenses for hardware, software, and services, as well as costs for planning, testing, and training. The cost may also include how much it costs to hire experts or consultants to help make the plan. But it's important to keep in mind that not having a disaster recovery plan can cost a lot more in lost revenue, data, and reputation.
