It becomes clear that Acronis didnt released build of Acronis Backup & Recovery, that will work on Windows Server 2012. Actually - support was not declared, but we can start Backup & Recovery on 2012... with a little trick.
Sympthoms: after Backup & Recovery installation, management console didnt start with reference to "Acronis Managed Machine Service" (the service didnt start) (service name - MMS).
