Learn how to develop disaster recovery strategies as well as how to write a disaster recovery plan with these step-by-step instructions. Formulating a detailed recovery plan is the main aim of the entire IT disaster recovery planning project. Once this work is out of the way, you’re ready to move on to developing disaster recovery strategies, followed by the actual plans. Once you have identified your critical systems, RTOs, RPOs, etc, create a table, as shown below, to help you formulate the disaster recovery strategies you will use to protect them. Once your disaster recovery strategies have been developed, you’re ready to translate them into disaster recovery plans. In addition to using the strategies previously developed, IT disaster recovery plans should form part of an incident response process that addresses the initial stages of the incident and the steps to be taken. It is in these plans that you will set out the detailed steps needed to recover your IT systems to a state in which they can support the business after a disaster. Then, you’ll need to establish recovery time objectives (RTOs) and recovery point objectives (RPOs).

Here we’ll explain how to write a disaster recovery plan as well as how to develop disaster recovery strategies. Procedures should ensure an easy-to-use and repeatable process for recovering damaged IT assets and returning them to normal operation as quickly as possible.
This process can be seen as a timeline, such as in Figure 2, in which incident response actions precede disaster recovery actions. The next section should define roles and responsibilities of DR recovery team members, their contact details, spending limits (for example, if equipment has to be purchased) and the limits of their authority in a disaster situation. Based on the findings from incident response activities, the next step is to determine if disaster recovery plans should be launched, and which ones in particular should be invoked. Once the plan has been launched, DR teams take the materials assigned to them and proceed with response and recovery activities as specified in the plans. Located at the end of the plan, these can include systems inventories, application inventories, network asset inventories, contracts and service-level agreements, supplier contact data, and any additional documentation that will facilitate recovery.
These are essential in that they ensure employees are fully aware of DR plans and their responsibilities in a disaster, and DR team members have been trained in their roles and responsibilities as defined in the plans.

Then define step-by-step procedures to, for example, initiate data backup to secure alternate locations, relocate operations to an alternate space, recover systems and data at the alternate sites, and resume operations at either the original site or at a new location. Here we can see the critical system and associated threat, the response strategy and (new) response action steps, as well as the recovery strategy and (new) recovery action steps. The more detailed the plan is, the more likely the affected IT asset will be recovered and returned to normal operation. Technology DR plans can be enhanced with relevant recovery information and procedures obtained from system vendors.
Check with your vendors while developing your DR plans to see what they have in terms of emergency recovery documentation.
