    Last Updated:Jul 29, 2025

    To prevent data loss or damage from accidental deletions, modifications, or overwrites, you can use Cloud Backup to periodically back up objects in buckets. If your objects are accidentally lost, you can use Cloud Backup to restore them. Cloud Backup provides flexible backup policies to back up data to the cloud. You can view and restore data at any time.

    Use the OSS console

    Configure scheduled backup for an existing bucket

    1. Log on to the OSS console.

    2. In the left-side navigation pane, click Buckets. On the Buckets page, find and click the desired bucket.

    3. In the navigation pane on the left, choose Data Management > Scheduled Backup.

    4. In the Scheduled Backup panel, create a backup plan.

      Create a free backup plan

      Cloud Backup provides a 30-day free trial for the scheduled backup of OSS data. No Cloud Backup fees are incurred during the free trial period.

      Important

      In a free backup plan, you cannot edit the source path or backup cycle. Each free backup plan uses an independent backup vault. You cannot change the backup vault after you convert the plan to a paid plan. If you want to back up all your data to the same backup vault, do not use a free backup plan.

      1. On the Backup Plan tab, click Create Backup Plan.

      2. In the Create Backup Plan panel, retain the default configurations.

      3. Click OK.

      Create a paid backup plan

      You can configure a paid backup plan to specify parameters such as the backup interval, the object files to back up, and the retention period.

      1. On the Backup Plan tab, click Create Backup Plan.

      2. In the Create Backup Plan panel, click Switch To Paid Plan.

      3. In the dialog box that appears, click Confirm.

      4. In the Create Backup Plan panel, configure the parameters as described in the following table.

        5. Parameter

        Description

        Backup Bucket Prefix

        Specify the prefix of the objects that you want to back up in the bucket. If you leave this parameter empty, all objects in the bucket are backed up.

        Backup Policy

        Select Create Policy. For more information about the configurations, see Manage backup policies.

        Use OSS Inventory

        Use the OSS inventory feature to back up OSS data. This feature can be used in scenarios where you back up a large amount of OSS data to significantly improve the performance of incremental backups. For more information about how to create a backup plan that uses the OSS inventory feature, see Back up a large amount of OSS objects using the OSS inventory feature.

      5. Click OK.

        Cloud Backup runs OSS backup jobs based on the specified start time and backup interval.

    Configure scheduled backup when you create a bucket

    1. Log on to the OSS console.

    2. Click Buckets, and then click Create Bucket.

    3. In the Create Bucket panel, enable Scheduled Backup. For more information about how to configure other parameters, see Create a bucket.

    4. Click OK.

      After the bucket is created, a backup plan is automatically created to back up data once a day and retain the backups for one week. This backup plan includes a 30-day free trial.

      To view or modify the created plan, you can choose Data Management > Scheduled Backup.
