Veeam and physical servers
Solution 1:
Veeam has had support for physical server backup in the last few releases.
This is detailed here on Veeam's product page and is accomplished by an OS-based agent.
In my experiences, it works well, but I have fewer and fewer physical servers to back up separately now, so it's not a prominent feature for my environments.
Solution 2:
sure, Veeam has agents (Windows and linux) for physical server I personaly configured it for physical servers bakcup and it works just fine
Veeam Agent for Windows
And
Veeam Agent for linux
