Server 2012 R2 - Registry Hive Recovered

Hi

A primary domain controller running Server 2012 R2 Standard keeps throwing one Event ID 5 with Source Kernel-General in the System Log periodically:

{Registry Hive Recovered} Registry hive (file): '\SystemRoot\System32\Config\RegBack\SYSTEM' was corrupted and it has been recovered. Some data might have been lost.

It allways happens right after an informational event-ID 16 Source: Kernel-General saying:
The access history in hive \SystemRoot\System32\Config\RegBack\SYSTEM was cleared updating 9558 keys and creating 1059 modified pages.

This has happened for a few weeks now during the night, and it allways happens two nights in a row before it's ok for a few days and then happens again.

The server is running in a virtual environment based on Server 2012 R2 HyperV.

Since this is in the RegBack folder - does that mean it's just the registry backup file that has problems?

What are the impacts from this and how to fix it?
