What is contained in the BMR portion of windows server backup (System drive only)?

Question

After successfully installing Windows Server 2016 on Dell PowerEdge T330, the system drive contains 4 partitions:
RESERVED 120 MB
RECOVERY 450 MB
SYSTEM 100 MB
PRIMARY 111 GB

When performing a Windows server backup on Windows server 2016, The successful completion shows the following data was saved on backup external drive:
EFI Partition 96.00 MB
C 88.31 GB
Recovery 325.38 MB
BMR 0 kb
System State 0 kb

So, what is included in BMR and where is it saved?
I can find documentation describing the contents of System State, but where is saved?

Thanks for any help you can provide,

Don

Hi,

System state backup: Backs up operating system files, enabling you to recover when a machine starts but you've lost system files and registry. A system state backup includes:
Domain member: Boot files, COM+ class registration database, registry
Domain controller: Active Directory (NTDS), boot files, COM+ class registration database, registry, system volume (SYSVOL)
Machine running cluster services: Additionally backs up cluster server metadata
Machine running certificate services: Additionally backs up certificate data

Bare metal backup: Backs up operating system files and all data except user data on critical volumes. By definition a BMR backup includes a system state backup. Provides protection when a machine won't start and you have to recover everything.

Windows Server Backup creates a folder called WindowsImageBackup on the root of the volume chosen as backup destination and all data is placed in this folder.
