## Ordering an increase with Terraform
{: #increasevault-terraform}
{: terraform}

To use Terraform, download the Terraform CLI and configure the IBM Cloud Provider plug-in. For more information, see the [Getting started with Terraform](https://cloud.ibm.com/docs/ibm-cloud-provider-for-terraform?topic=ibm-cloud-provider-for-terraform-getting-started&format=markdown) tutorial.
{: requirement}

Use the `ibm_storage_evault` resource to update your IBM Cloud® Backup for Classic instance. The following example increases the vault capacity to 100 GB when it is applied.

```terraform
resource "ibm_storage_evault" "test" {
  datacenter          = "dal13"
  capacity            = "100"
}
```
{: codeblock}

For more information about arguments and attributes, see [ibm_storage_evault](https://registry.terraform.io/providers/IBM-Cloud/ibm/latest/docs/resources/storage_evault){: external}.


## Billing
{: #changeinbilling}

Billing for the volume is automatically updated to add the prorated difference of the new price to the current billing cycle. Then, the full new amount is billed in the next billing cycle.
