kernel source/dkms issue

[Roman Shein]

I cannot build kernel module for Acronis Backup.
Here below is dkms make.log.
The same module compiles just fine on Debian 9. Proxmox is installed on top Debian 9, thus it seems that Proxmox kernel is a culprit.
Despite being installed in non-standard way Proxmox itself function just fine.

Acronis Backup is not supported by Acronis on either Debian 9 or Proxmox. (even kernel wise)

Acronis builds and works just fine on Debian 9 native kernel.

well the compiler errors you get refer to stuff that changed in kernel 4.8, so either that is not true (Stretch uses 4.9, PVE uses a patched 4.10) or the detection logic in the build files is broken and thinks PVE uses an older kernel.
