Using a Backup to Create a File System

In case of a virus attack, accidental deletion, or software or hardware fault, you can use an SFS Turbo file system backup to create a new file system. Once created, data on the new file system is the same as that in the backup.


  1. Log in to CBR Console.

    1. Log in to the management console.
    2. Click in the upper left corner and select your region and project.
    3. Click and choose Storage > Cloud Backup and Recovery. Select a backup type from the left navigation pane.

  2. Click the Backups tab and locate the desired backup. For details, see Viewing a Backup.
  3. If the status of the target backup is Available, click in the Operation column of the backup.

  4. Configure the file system parameters.

    • You can learn about the parameter descriptions in table "Parameter description" under "Creating an SFS Turbo File System" in Create a File System.
    • You can change the storage class of the file system within a certain range. For example, you can change a file system from Standard to Performance, but not from Standard to Standard - Enhanced.
    • The billing mode of the new file system can only be pay-per-use.

  5. Click Next.
  6. Confirm the file system information and click Submit.
  7. Make the payment and click OK.
  8. Go back to the file system list and check whether the file system is successfully created.

    You will see the file system status change as follows: Creating, Available, Restoring, Available. You may not notice the Restoring status because Instant Restore is supported and the restoration speed is very fast. After the file system status has changed from Creating to Available, the file system is successfully created. After the status has changed from Restoring to Available, backup data has been successfully restored to the created file system.
