Backups using a specific hardware provider do not work, provider is missing from the user interface:
Veeam fails over to a software provider which does not have the functionality of a hardware provider (e.g. off-host proxy, fast snapshot creation, etc.)
On the Veeam Backup & Replication server, please create the following registry key:
HKLM\SOFTWARE\VeeaM\Veeam Backup and Replication UIShowAllVssProvidersForVolume
After creating the registry key, please restart the Veeam services and make sure that the required provider is visible and can be selected.
Please be aware that we’re making changes which will restrict access to product updates for users without an active contract.
