Synchronizing Data to a Single-Replica Instance

Scenarios

GaussDB allows you to synchronize data from a three-replica instance to a single-replica instance.

Precautions

• If the instance or any of its nodes is abnormal, you cannot perform this operation.
• If you are performing other operations on a single-replica instance, this operation is unavailable.
• After this operation is performed, all data on the target single-replica instance, including its password, will be overwritten.

2. Click in the upper left corner and select a region and project.
3. Click in the upper left corner of the page and choose Databases > GaussDB.
4. On the Instances page, click More in the Operation column of the target instance and choose Synchronize Data to a Single-Replica Instance.
