You can store data in your own cloud or in the Metallic cloud.
The following clouds are supported:
HPE StoreOnce stand alone library
Metallic Recovery Reserve
Amazon Web Services
Important: If you must have all data traffic reside in your Azure cloud account due to firewall restrictions or use Azure IAM VM roles, deploy a Metallic backup gateway. The backup gateway must be deployed in the same region as the data you are backing up.
If you want to deploy a backup gateway for your Azure account, contact Metallic Customer Success Manager.
