Hyper-v client - file backup VM


I’m using the hyper-V client on the host server. All VM’s discover correctly, but by default only image backups are enabled.
I want to run file backups for the VM’s as well, so I manually changed the config for a few specific VM’s.
This ‘worked’, it started a file level backup job for those VM’s. However, the files that have been backed up are from the host server, not the VM.

Hyper-V server: hvhost (Server 2022 DC running 2.2.20-hyperv)
client: hvhost[VM01] (Server 2016 DC)
urbackup server: v2.4.15 (Debian 11)

The file backup for hvhost[VM01] C:\ shows the files for hvhost c:\

What am I doing wrong?
