When configuring Disaster Recovery (DR) for an Oracle database using Nutanix Database Service (NDB), how...

NDB implements Oracle database disaster recovery by orchestrating Oracle Data Guard, not by duplicating every write through cross-site iSCSI or relying on a generic guest replication agent. The NDB Oracle workflow provisions or manages a standby database on the remote cluster and configures the native Data Guard relationship, including redo transport and the supported protection mode. This lets administrators manage DR through the NDB console and APIs and perform planned or unplanned role transitions within the supported workflow. Nutanix storage snapshots and Time Machine replication remain important for backup, clone, and restore operations, but scheduled snapshot replication is not the mechanism used to continuously maintain an Oracle DR standby. Therefore, deploying the remote Oracle instance and configuring native Oracle Data Guard log transport is the correct architecture. Nutanix documents this capability under Oracle Database Disaster Recovery.
