Scenarios
This section describes how to use an automated or manual backup to restore an RDS instance to the status when the backup was created. The restoration is at the DB instance level.
When you restore a DB instance from a backup file, the backup file is downloaded from OBS and then restored to the DB instance at an average speed of 100 MB/s.
Procedure
- Log in to the management console.
- Click
in the upper left corner and select a region and a project. - Click
in the upper left corner of the page and choose Database > Relational Database Service. - On the Backups page, select the backup to be restored and click Restore in the Operation column.
Alternatively, click the target DB instance on the Instances page. On the displayed page, choose Backups & Restorations. On the displayed page, select the backup to be restored and click Restore in the Operation column.
- Select a restoration method and click OK.
- Create New Instance
The Create New Instance page is displayed.
- The DB engine and engine version of the new instance are the same as those of the original instance.
- The new instance must have at least the same storage space as the original instance.
- Other settings are the same as those of the original DB instance by default and can be modified. For details, see Buying an RDS for MySQL Instance.
- Create New Instance
- View the restoration result. The result depends on which restoration method was selected:
- Create New Instance
A new DB instance is created using the backup data. The status of the DB instance changes from Creating to Available.
The new DB instance is independent of the original one. If you need read replicas to offload read pressure, create one or more for the new DB instance.
After the new instance is created, a full backup will be automatically triggered.
