Disaster Recovery Overview

Disaster recovery is a key sub-program of Oracle Risk Management Resiliency Program (RMRP). To understand resilience, business continuity, and disaster recovery practices for cloud services, please see Oracle Cloud Hosting and Delivery Policies.

Oracle Lines of Business (LOBs) are required to maintain and test their Disaster Recovery (DR) plans, including backup and recovery strategies, as part of their business continuity efforts.

Disaster Recovery (DR) plans focus on the resiliency of computing infrastructure supporting Oracle’s internal operations and cloud services. Oracle’s production data centers are geographically separated and have component and power redundancy, with backup generators in place for availability of data center resources in case of an impacting event. LOB recovery strategies are designed to both protect against disruption and enable recovery of services including backups for identified critical systems. For these systems, Oracle performs the following backups as applicable:

• Database: Full and incremental backups
• Archive logs: Full and incremental backups

Oracle LOBs also implement additional DR strategies for certain critical systems, such as:

• Application failover
• Current copy of the production database at a secondary site using solutions such as Oracle Data Guard, which manages the two databases. Oracle Data Guard provides remote archiving, managed recovery, switchover, and failover features.
• Redundant middle or application server tiers consisting of a set of servers to distribute application functionality across multiple host machines.
• Physical backup media such as tape is periodically relocated to a secure offsite location

Further, Oracle also maintains a redundant network infrastructure, including DNS servers to route between primary and secondary sites, network devices, and load balancers.

Finally, Oracle information technology organizations conduct an annual DR exercise for internal infrastructure designed to assess their DR plans. Lessons learned from the exercise are implemented into standard operations and DR procedures as appropriate.
