Managing EVS Backups


EVS disk backups are created using the CBR service. For details, see Creating a Cloud Disk Backup in the Cloud Backup and Recovery User Guide.

You can configure a backup policy for disks. With backup policies configured, data on EVS disks can be periodically backed up to improve data security.


  • Backups can be created only when the disks are in the Available or In-use state.

  • Only users with the CBR FullAccess permissions can use the cloud disk backup function. If the user does not have the permissions, contact the account administrator to grant the permissions first.

    • Only Available and In-use disks can be selected.

    • You can also associate disks with the vault you are creating later if you skip this step.

  4. Specify a vault capacity ranging from the total sizes of disks to 10,485,760 GiB.

  5. Configure auto backup.

    • If you select Configure, you must then select an existing backup policy or create a new one. After the vault is created, the system applies this backup policy to the vault, and all disks associated with this vault will be automatically backed up based on this policy.

    • If you select Skip, disks associated with this vault are not automatically backed up.

  6. Specify a name for the vault.

    The name can contain 1 to 64 characters including digits, letters, underscores (_), and hyphens (-), for example, vault-612c.


    You can use the default name, which is in the format of vault_xxxx.

  7. Click Next.

  8. Complete the creation as prompted.

  9. Go back to the disk backup page. The vault you created is displayed in the list.

    You can associate disks to the new vault or create backups for the disks. For details, see section "Vault Management" in the Cloud Backup and Recovery User Guide.
