Hello WiktorKostrzewski,

In this case it would be recommended to run the next command as Administrator in the virtual machine's host

vssadmin list providers
vssadmin list shadow

Reference: https://docs.microsoft.com/en-us/previous-versions/windows/it-pro/windows-server-2008-R2-and-2008/cc734302(v=ws.10)?redirectedfrom=MSDN#make-sure-that-vss-hardware-providers-are-operating-properly

Additionally, you can try to install the next update specifically for Windows Server 2012R2:
"Hyper-V integration components update for Windows virtual machines"
https://support.microsoft.com/en-us/topic/hyper-v-integration-components-update-for-windows-virtual-machines-8a74ffad-576e-d5a0-5a2f-d6fb2594f990

And last but not least, please check if the Virtual Machine has enabled the "Backup (volume checkpoint)" integration service, with the next steps:
1. in Hyper-V right click the virtual machine, and select Settings
2. Go to the Integration Services option from the left menu
3. Ensure that the Backup option is marked
