I have a Server 2012 R2 machine that was upgraded from Server 2008 R2. I use Windows Server Backup to backup the system and have no issues backing up to a WD Elements 2TB disk.
If I attempt a System Image Restore, a message box is displayed titled "Re-Image Your Computer" with the message "Scanning for System Image disks" and the system hangs doing the scan.
If I cancel this message box and select the advanced option to connect to the network, a similar thing occurs - the system displays the messages box with "Connecting to the network ..." and hangs.
I am therefore unable to perform a system image restore.
