# ADVREL05-BP02 Create disaster recovery (DR) runbooks, and regularly test documented backup and restoration processes
Processes for backup, restoration, and failover of data should be documented and regularly tested to validate efficacy and understanding.
## Implementation guidance
Advertising workloads are designed for low latency when accessing information. An unsuccessful or slow data restoration could result in negative impact to the workload. To mitigate the impact from data unavailability during a disaster, implement data backup mechanisms which can quickly make necessary data available. By documenting processes, incident response teams can address impactful events, while validation ensures that the processes will work when needed, and that team members are comfortable, and confident, in performing disaster response activities quickly.
## Key AWS services
+ [AWS Elastic Disaster Recovery (DRS)](https://aws.amazon.com/disaster-recovery/) is a service that can help design a DR solution, map applications and networks, and build and test a DR runbook
+ [AWS Config](https://aws.amazon.com/config/) can be used to continuously monitor and record resource configurations
+ [AWS CloudFormation](https://aws.amazon.com/cloudformation/) can detect drift in stacks that have been deployed
