Best practices for Enterprise disaster recovery (DR) basically consist of designing and implementing fault-tolerant hardware and software systems that can survive a disaster (business continuance) and resume normal operations (business resumption), with minimal intervention and, ideally, with no data loss. Building fault-tolerant environments to satisfy Enterprise DR objectives can be expensive and time consuming and requires a strong commitment by the business.
Oracle Database provides three different approaches to DR that provide the highest level of data protection and availability compared to any other approach for protecting Oracle data.
