Hi,
According to the Microsoft, we could do bare metal restore to the same physical computer , or to a different physical computer that has the same make, model, and configuration (identical hardware).
It is not support to restore from one computer to a second computer of a different make, model, or hardware configuration.
Please also check the KB below.
Based on my knowledge, Full Server Backup is anything in your system, but Bare Metal is anything that is needed for your system's OS and its applications. And also note that, Bare Metal is already included in Full Server Backup.
If the server is a DC, for Active Directory backup and restore best practice, please also check the thread discussed below.
Best Regards,
