Create a MariaDB Cluster from a Backup

The request creates a new MariaDB cluster, which involves restoring a backup of an existing MariaDB cluster and configuring it to function as a new cluster. Ensure you have a backup of your MariaDB cluster containing all the necessary data and configuration files for appropriate functioning.

Prerequisite

• Only contract administrators, owners, and users with Access and manage DBaaS privilege can create and manage MariaDB clusters. Ensure that you have the necessary privilege.

Request

Note:

• After creating a database, you can access it via the corresponding LAN using the same username and password specified during creation.

• This is the only opportunity to set the username and password via the API. The API does not provide a way to change the credentials yet. However, you can change them later using raw SQL.

• The data center must be provided as a UUID. The easiest way to retrieve the UUID is through the Cloud API.

• The sample UUID in the example is 498ae72f-411f-11eb-9d07-046c59cc737e.

Response

Your values will differ from those in the sample code. It may contain different IDs, timestamps etc.

The created cluster is returned with metadata.state set to BUSY, which indicates that the cluster is not yet reachable. This is because the cloud will create a completely new cluster and needs to provision new nodes for all the requested replicas.

After creation, remember to validate the status of your MariaDB cluster. For more information, see Verify the Status of a MariaDB Cluster.
