Zero Data Loss Protection with Local Autonomous Data Guard Standby

For Autonomous Data Guard, zero data loss protection (RPO = 0) is provided for a local standby database. Autonomous Data Guard performs automatic failover to a local standby database when a standby is available and the system guarantees zero data loss. If a data loss limit is specified (0 to 3600 seconds), failover occurs within the defined limit.

See Use Standby Databases with Autonomous Data Guard for Disaster Recovery for more information.
