Possibility to restore VHD without restore-img

I have trouble to boot restore img from pxe;
so I am start thinking to do vhd-restoration with diskgenius;
a guest-only samba share is enabled in urbackup server.
boot WEPE from pxe, restore one vhd by using diskgenius, reboot, everything’s ok.
It seems all good.
but what about full-disk restoration?
create partitions , and restore them one by one?

what does these files for ?
cbitmap/hash/mbr/sync
