Challenge
Backups using a specific hardware provider do not work, provider is missing from the user interface:
Cause
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.)
Solution
On the Veeam Backup & Replication server, please create the following registry key:
HKLM\SOFTWARE\VeeaM\Veeam Backup and Replication UIShowAllVssProvidersForVolume
REG_DWORD
1
After creating the registry key, please restart the Veeam services and make sure that the required provider is visible and can be selected.
More Information
This value disables the advanced compatibility step which automatically chooses the best compatible providers.
