Chapter 8 Quality attributes and sizing of the dXp the historical outage incidents. We should carry out a business impact analysis for critical business processes; the impact analysis exercise will help us to map each of the business-critical processes to the component and DR process. The business impact analysis also helps us to define the RTO for the corresponding DR process. We should also examine existing contingency policies and data backup processes. During this phase we will also finalize the metrics such as RPO and RTO for the site. We will define the DR activities and processes to achieve the RPO and RTO. A sample list of DR activities is given in Table 8-2. Table 8-2. Sample DR Activities DR Activity Process Comments dr site setup site setup Create a dr site as a mirror replica of the primary site as a process one-time setup process. Code backup Code backup Code is synchronized on a daily basis. the synchronization process frequency is adjusted based on the rpo. data backup data backup data is synchronized on a daily basis. the synchronization process frequency is adjusted based on the rpo. Content backup Web content Content is synchronized on a daily basis. the synchronization backup process frequency is adjusted based on the rpo. dr site switching site switching the emergency response process details the steps to switch processes from primary site to dr site. The infrastructure architect defines the governance model and details all the required infrastructure-related processes. Most of the synchronization processes will be configured as scheduled batch jobs. The infrastructure architect reviews the metrics, activities, and processes with all stakeholders and gets their signoff. The infrastructure architect also defines the communication process for internal and external stakeholders as part of DR process definition. Once the DR processes and activities are finalized, the infrastructure architect defines the schedule for implementing the planned DR activities. DR Implementation During the implementation phase, we assign the resources for each of the planned activities based on the schedule and priority. 230
