Reset to device error on Windows 2012 Server

I am running Windows Server 2012 as a guest VM on a Hyper-V server.  Every night I get the following warning errors in my event log:  "Reset to device \device\RaidPort1 was issued".  The source is vhdmp and the event id is 129.  It happens multiple times and seems to coincide with a Windows Server backup that runs nightly to an external hard drive.  This does not seem to have an impact on the server.  Reboots are not necessary and the errors do not occur during normal daily operation.  However, I am uncomfortable just ignoring the message.  Is this safe to ignore?  I have seen other posts where this error requires a hard reboot of the server.  In my case, it happens overnight and has not caused problems so far (to my knowledge).

This guy has a very similar issue: Event ID 129 – storachi - Reset to device, \Device\RaidPort0, was issued. It has to do with power management. You can try his solution on the VM guest first. If it persists, try it on the host, too.
I assume that the backup is unattanded, so maybe the same "innocent" hangs (linked article) occur to your server, too, but you might have no clue about them.
