Using a Backup to Create a Disk
You can create new disks from backups. Once created, the new disks will contain the backup data.
The new disks created using system disk backups can only be used as data disks on servers. They cannot be used as system disks.
Disk backups can only be used to create EVS disks, not servers.
- Log in to CBR Console.
- Log in to the management console.
- Click in the upper left corner and select your region and project.
- Click and choose Storage > Cloud Backup and Recovery. Select a backup type from the left navigation pane.
- Click the Backups tab. Locate the desired backup. For details, see Viewing a Backup.
- If the status of the target backup is Available, click Create Disk in the Operation column of the backup.
- Configure the disk parameters.
See the parameter description table in section "Purchase an EVS Disk" of the Elastic Volume Service User Guide for more information.
Pay attention to the following:
- You can choose the AZ to which the backup source disk belongs, or a different AZ.
- The new disk must be at least as large as the backup's source disk.
If the capacity of the new disk is greater than that of the backup's source disk, format the additional space by following the steps provided in section "Extending Disk Partitions and File Systems" of the Elastic Volume Service User Guide.
- You can create a disk of any type regardless of the backup's disk type.
- Click Next.
You can choose Pay-per-use or Yearly/Monthly as your Billing Mode. The following steps use the Yearly/Monthly billing as an example.
- Confirm the disk information and click Submit.
- Make the payment and click OK.
- Go back to the disk list. Check whether the disk is successfully created.
You will see the disk 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 disk status has changed from Creating to Available, the disk is successfully created. After the status has changed from Restoring to Available, backup data has been successfully restored to the created disk.
