Understanding business continuity and disaster recovery for Cloud Databases
Disaster recoveryThe ability of a service or workload to recover from rare, major incidents and wide-scale failures, such as service disruption. This includes a physical disaster that affects an entire region, corruption of a database, or the loss of a service contributing to a workload. The impact exceeds the ability of the high availability design to handle it. involves a set of policies, tools, and procedures for returning a system, an application, or an entire data center to full operation after a catastrophic interruption. It includes procedures for copying and storing an installed system's essential data in a secure location, and for recovering that data to restore normalcy of operation.

Disaster recovery strategy
IBM Cloud has business continuityThe capability of a business to withstand outages and to operate mission-critical services normally and without interruption in accordance with predefined service-level agreements. plans in place to provide for the recovery of services within hours if a disaster occurs. You are responsible for your data backup and associated recovery of your content.
Cloud Databases provides mechanisms to protect your data and restore service functions. Business continuity plans are in place to achieve targeted recovery point objectiveIn disaster recovery planning, the time at which data is restored measured in time (seconds, minutes, hours) starting at the recovered instance and ending at the point of disaster. (RPO) and recovery time objectiveIn disaster recovery planning, the duration of time for a business process to be restored after a disaster. (RTO) for the service. The following table outlines the targets for Cloud Databases.
| Disaster recovery objective | Target value |
|---|---|
| RPO | < 24 hours |
| RTO | <24 hours - for Regional failure (0 hours for Zone Failure) |
Locations

Backup storage regions
The purpose of the Cloud Databases regional Disaster Recovery (DR) policy is to make IBM Cloud® Object Storage backups available from the downed region available for you to restore.
