You can create backup policies for clusters that need to be backed up. After you create a backup strategy, you can view the backup status of the cluster on the Cluster Overview page.
Procedure
In the left-side navigation pane, choose Backup & Recovery > Backups .
On the Backups page, click New Backup Strategy .
Select the cluster to backup in the drop-down list.
For a cluster earlier than OceanBase Database V2.2.60, logical backup is used.
For a cluster of OceanBase Database V2.2.60 and later, physical backup is used.
Enter the following storage configuration parameters and click Test .
For logical backup, select the storage configuration configured during service installation.
If no backup or recovery service is installed, first click Install Service to install a service, and then create the backup strategy. For more information, see Install a service.
For physical backup, specify fields in the following table.
Parameter Description Storage Configuration Name You can customize the configuration or select an existing one. * For a custom configuration, specify the following fields. * If you already have an existing configuration, click Select Existing Configuration . Then, the system will automatically populate the following fields. Storage Type The type of the storage media for backup files. Valid values: * File: Your local file storage system. Generally, the Network File System (NFS) is used. * OSS: Alibaba Cloud Object Storage Service (OSS) is supported only in OceanBase Database V2.2.76 and later. * COS: Tencent Cloud Object Storage (COS) is supported only in OceanBase Database V2.2.76 and later. Storage Directory The directory where the backup files are stored on the media. Alert Threshold for Backup Storage Capacity The default threshold is 80%. An alert is triggered when the utilization of the backup storage reaches this threshold. Domain * If you select OSS in the Storage Type field, enter the domain name that has access to the files stored at OSS of Alibaba Cloud. * If you select COS in the Storage Type field, enter the domain name that has access to the files stored in the COS bucket of Tencent Cloud. For example: cos.ap-shanghai.myqcloud.com. User If you select OSS in the Storage Type field, enter the user that has access to the files stored at OSS of Alibaba Cloud. AccessKey Pair If you select OSS in the Storage Type field, enter the AccessKey that has access to the files stored at OSS of Alibaba Cloud. Resource Identity (APPID) When Storage Type is COS, move the pointer over the question mark ( ? ) and enter the content as prompted. Project ID When Storage Type is COS, move the pointer over the question mark ( ? ) and enter the content as prompted. Project Key When Storage Type is COS, move the pointer over the question mark ( ? ) and enter the content as prompted. 
Enter the scheduling configuration parameters
Scheduling Cycle: The scheduling cycle can be a week or a month. When you set it to Month, you can only select up to ten days.
If you need to perform a physical backup task, the Initiate Log Backup switch must be turned on.
Schedule the cleaning of expired backup files.
Note
At present, the cleaning of expired backup files is not supported when the storage type is OSS.
Configure alert thresholds. You can define the timeout threshold for data backup tasks, alert threshold for log backup delays, and the threshold for the number of days without successful data backup. After you set a threshold, an alert is triggered when the threshold is reached.
(Optional) Configure a secondary backup task
To configure a secondary backup task, turn on the switch.
Configure scheduling settings for a secondary backup task.
Configure storage settings for a secondary backup task.
NoteThe backup files of secondary backup and regular backup tasks must be stored at different locations. This is because a secondary backup task backs up the existing backup files and ensures that an OceanBase cluster can be recovered when the backup data of a regular backup task is affected by disasters.
