Understanding business continuity and disaster recovery for CIS
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.
CIS 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 CIS.
| Disaster recovery objective | Target value |
|---|---|
| RPO | Failover happens almost instantly (within seconds) if internal, as it switches to another cluster. However, if Cloudflare experiences downtime or issues, data will be unavailable until they are back online, as CIS is a stateless service. |
| RTO | Recovery time for CIS is approximately 1 hour per cluster, including verification and other processes. |
