Disaster Recovery using Oracle Dataguard

Disaster Recovery using Oracle Dataguard


Oracle Data Guard provides the management, monitoring, and automation software to create and maintain one or more standby databases to protect Oracle data from failures, disasters, human error, and data corruptions while providing high availability for mission critical applications.

Organizations are recommended to implement Dataguard in a separate DR site and the DR site to be located at a remote location far from the primary.

Data Guard offers various deployment options that address unplanned outages, pre-production testing, and planned maintenance. Active Data Guard, an extension of basic Data Guard capabilities, further enables production offload of read-only workload to a synchronized physical standby database, automatic repair of corrupt blocks, and offload of fast incremental backups.
