Event 129 - vhdmp during Backup Windows 2012 Std

Hello,

almost everytime when i am trying to backup Windows Server 2012 Std. over night i get an error, backup freez and server shared files are blocked. In event viewer its event ID 129 "Reset to device, \Device\RaidPort3, was issued" and this error repeat every second until i cancel backup process or disconnect backup target. I backup to QNAP TS-412 iSCSI disc. Windows and QNAP have all updates. I tryed change switch and qnap ports but its still same. I found this problem on many forums but cant finy any solution.

Can somebody help me?

Thank you.

You have not provided any informtion on server hardware and its configuration. My guess is that there is reconfigured power option.

Another cause is described here
