Cloud Backup:Back up a large amount of OSS objects by using the OSS inventory feature

Usage notes

Create a backup plan to periodically back up many OSS files

To create a backup plan, perform the following steps.

1. Log on to the Cloud Backup console.

2. In the navigation pane on the left, choose Backup > OSS Backup.

3. In the top menu bar, select the region where the OSS bucket resides.

4. On the OSS Backup page, click Create Backup Plan.

5. In the Create Backup Plan panel, configure the parameters as described below, and then click OK.

   Note

   • You can use a free backup plan for one month from the date of creation. For example, if you create a backup plan on February 14, 2020, the free plan expires on March 14, 2020. Using this feature to back up OSS data incurs OSS request fees and OSS manifest storage fees. These fees are charged by OSS. For more information, see OSS billing methods.

   • A free trial plan has limitations. You cannot edit the source path or backup cycle. Each free trial plan uses a separate backup vault. You cannot change the backup vault after you switch to a paid plan. If you plan to back up all your data to the same backup vault in the future, do not use a free trial plan.

   This topic uses a paid plan as an example to describe the parameter configurations. The configuration for a free plan is similar.

   1. Click Switch to Paid Plan, and then click OK in the dialog box.

   2. Configure the basic settings as described in the following table.

      Important

      • If the region that you select supports backup policies, you can set a backup plan only by attaching it to a backup policy. Cloud Backup then periodically backs up OSS data based on the backup policy.

      • In the navigation pane on the left of the console, click Policy Center to view the regions that support backup policies. For more information about how to create a backup policy, see Create a backup policy.

      Parameter	Description
      Source OSS Bucket	Select the name of the OSS bucket to back up from the drop-down list. Cloud Backup automatically obtains a list of all buckets in the region under your account.
      Source Path	Select a directory of the bucket to back up from the drop-down list. If you do not select a directory, the entire root directory of the bucket is backed up by default.
      Include Specified Object	Backs up only the objects that match the regular expression. If you do not specify a regular expression, all objects are included. Important If an object matches both the inclusion and exclusion rules, the object is not backed up.
      Exclude Specified Object	Does not back up the objects that match the regular expression. If you do not specify a regular expression, no objects are excluded.
      Backup Policy	Select a suitable backup policy from the drop-down list. Cloud Backup automatically backs up the data source according to the backup policy you set. A backup policy mainly includes settings such as the backup vault encryption method, backup interval, retention period, cross-region replication policy, and automatic data archiving. This helps you flexibly manage your data source assets. If the default backup policy does not meet your requirements, click Create Backup Policy or Edit Policy to manage backup policies. For more information about the parameters in a backup policy, see Policy center.
      Performance Optimization
      Use OSS Inventory	Specifies whether to use the OSS inventory feature to back up OSS files. For this scenario, set this to Select Inventory. No: Does not use the OSS inventory feature. Objects are backed up by traversing them. Select Inventory: Uses an existing OSS inventory file for backup to improve the performance of incremental OSS backups.
      OSS Inventory Name	This parameter is required only when Use OSS Inventory is set to Select Inventory. From the OSS Inventory Name list, select a created OSS inventory. Using the OSS bucket inventory feature incurs fees. For more information about the fees, see Bucket inventory billing. The created OSS inventory file must meet the following conditions: The inventory file must be of the current version and enabled. Its bucket prefix must be the same as the value of the Source Path parameter. The inventory file must include the Object size, storage class, last updated date, and ETag fields. The generation cycle of the OSS inventory file cannot be longer than the backup cycle. This ensures that an OSS inventory file can be used for each backup.
      Delete inventory file after backup	Specifies whether to delete the inventory file after the backup plan is complete. This operation deletes the inventory file of the bucket. We recommend that you place the inventory file in a separate bucket or select Do Not Delete to manage it manually. Do Not Delete: Does not delete the inventory file. We recommend this option if other applications access the OSS inventory file. Delete Current: Deletes the inventory file used in the current backup job. Delete All: Deletes all inventory files generated before this backup after the backup is complete. We recommend this option if no other applications access the OSS inventory file.

   After the backup plan is created, its status is Running. Cloud Backup runs OSS backup jobs at the specified start time and backup interval.

Backup successful

• When the scheduled backup time arrives, Cloud Backup starts and runs the backup job.

  Note

  The backup progress percentage is a dynamic estimate that the system generates based on the current data volume and is for reference only. It may not reflect the exact completion percentage. During the backup process, the displayed total scanned size may be smaller than the actual total data size because the data scan is not yet complete. The completion of the backup job is determined by its final status.

  On the Backup Jobs tab, if the Status of a backup job is Completed, the backup is successful.

  View details about the backup job, such as Total Scan, Completed Backups, Written to Vault, and Backup Speed. For more information about these metrics, see the tooltips in the Cloud Backup console.

  Note

  For backup jobs completed on or after June 1, 2025, statistics for both data volume and file count are displayed for Total Scanned at Source, Backup Completed, and Data Written to Vault. For backup jobs completed before this date, only data volume statistics are shown for these metrics.

  

• On the Backup Plans tab, click the icon next to the target bucket to view the backup records and information about the generated backup points in the Backup History section. You can then restore OSS files based on these historical backup points.

  

Troubleshooting

If the Status of a backup plan or backup job is abnormal, refer to the following suggestions to resolve the issue.

• Status of the backup job: Failed (The OSS bucket does not exist.)

  The OSS bucket has been deleted.

  • If the OSS bucket was deleted as expected, ignore the backup job status. To avoid extra backup storage fees, we recommend that you click Storage Vaults in the navigation pane on the left, find the corresponding backup vault, and delete it.

  • If the OSS bucket was deleted by mistake and you want to restore it, create an OSS bucket in the corresponding region. Use this OSS bucket as the restore destination to complete the OSS file restore. For more information, see Create an OSS restore job.

• Status of the backup job: Failed (No OSS inventory list is available. Please wait for the next backup when the latest inventory list is automatically detected and used.)

  The corresponding OSS inventory file was not found in the specified directory (prefix). Go to the OSS console to check whether the bucket inventory file has been created.

• Backup plan Status: Suspended

  The backup plan has been paused. After a plan is paused, Cloud Backup no longer protects the OSS bucket. We recommend that you resume the backup plan as soon as possible.

Browse and download backup files

• Browse backup files

  You can use the Browse feature to view files that have been backed up.

  1. On the Backup Plans tab, click the icon next to the target OSS bucket.

  2. In the Backup History, find the backup point for the desired time and click Browse.

     

• Download backup files

  You cannot directly download backed-up files. You can restore the files to a specified temporary OSS path, which is free of charge, and then download the files from OSS.

Cross-region backup

To prevent regional disasters from affecting business continuity, Cloud Backup lets you create a mirror vault for a general-purpose backup vault. Data in the backup vault is automatically replicated to the mirror vault to implement cross-region geo-redundancy. You can create a mirror vault for a general-purpose backup vault that stores OSS files. For more information, see Cross-region backup.

You can create mirror vaults for general-purpose backup vaults that you create using features such as ECS file backup, SAP HANA backup, General-purpose NAS backup, on-premises NAS backup, and on-premises file backup. These vaults also support enterprise-grade features such as cross-account backup, automatic archiving, KMS encryption, and backup locking.
