You can use Cloud Backup in combination with Object Storage Service (OSS) to periodically back up objects in buckets. This way, you can use backups to restore objects that are corrupted or lost due to factors such as accidental deletions, modifications, and overwrites. Cloud Backup allows you to configure flexible backup policies to back up data to the cloud. You can view your backups and use them to restore data at any time.

If Cloud Backup is not authorized to read data from OSS, perform the following steps to complete the authorization: Log on to the Cloud Backup console, click OSS Backup in the left-side navigation pane, and then follow the on-screen instructions to authorize Cloud Backup to read data from OSS.
Billing
When you back up data stored in OSS buckets using cloud backup, storage and API operation calling fees will be incurred. For more information, see Billing.

In the Scheduled Backup panel, create a backup plan.
Create a free backup plan
Cloud Backup provides a 30-day free trial of scheduled backup.
ImportantA free backup plan does not allow you to change the Source Path and Backup Interval parameters. Each free backup plan uses an independent backup vault, and the vault cannot be changed even if you pay for the plan after the free trial expires.

On the Backup Plans tab, click Create Backup Plan.
In the Create Backup Plan panel, retain the default settings.
Click OK.
Create a paid backup plan
You can configure a paid backup plan to specify the backup interval, the objects that you want to back up, and the number of days for which you want to retain backups.
On the Backup Plans tab, click Create Backup Plan.
In the Create Backup Plan panel, click Switch to Paid Plan below the Source OSS Bucket parameter.

Use OSS Inventory
Specify whether to enable the OSS inventory feature to back up data from the OSS bucket. If you need to back up a large amount of data, you can use the OSS inventory feature to accelerate incremental backup. For more information about how to use scheduled backup with the inventory feature, see Back up a large amount of OSS objects by using the OSS inventory feature.
