Cloud SQL Advanced Disaster Recovery (DR) allows organizations to provision a cross-region read replica in an alternate region (such as us-east4) and perform an immediate replica failover during an unexpected disaster or regional outage.
us-central1 comes back online after the disaster, Cloud SQL automatically takes a final backup to preserve any split-brain transactions that occurred before the primary went offline.us-east4.This approach provides an out-of-the-box, fully managed solution that fulfills all data persistence, backup continuity, and automated multi-region topology requirements without custom scripting or significant administrative overhead.
