Scenarios:

If you use DB instances only for routine development, you can temporarily stop pay-per-use DB instances to save money. You can stop a DB instance for up to seven days.

Constraints:

• If you stop a primary DB instance, read replicas (if there are any) will also be stopped. They are stopped for up to seven days. You cannot stop a read replica without stopping the primary DB instance.
• A stopped DB instance will not be moved to the recycle bin after being deleted.
• After a DB instance is stopped, the ECS is no longer billed. Other resources, including EIPs, storage resources, and backups, are still billed.

 Procedure:

• Step 1 Log in to the management console.
• Step 2 Click in the upper left corner and select a region and a project.
• Step 3 Click Service List. Under Database, click Relational Database Service. The RDS console is displayed.
• Step 4 On the Instance Management page, locate the primary DB instance that you want to stop and choose More > Stop in the Operation

• Step 5 In the displayed dialog box, click Yes.

• Step 6 Refresh the DB instance list and view the status of the DB instance. If the status is Stopped, the DB instance has stopped successfully.

To start up a database, follow steps one through six. In step four, the option Start will be displayed instead of Stop.
