What Do I Do If I Cannot Create an Image from a CSBS Backup or BMS Using a Subaccount with the Allow_all Permission After EPS Is Enabled?

When an enterprise project subaccount is used to create an image, the system displays a message indicating that CSBS or BMS is not supported by EPS.

This is because CSBS and BMS are not interconnected with EPS regionally or globally. The global resource viewing permission must be granted to the subaccount in IAM. For example, you can view resources of other cloud services if you have the Tenant Guest permission.
