I recently upgraded my Win 8.1 Pro to Win 10 Pro. Previously backup to my WHS 2011 was running perfect. After upgrade to Win 10 I encountered problems with the upgrade and had to go back and install Win 8 Pro then Win 8.1 Pro then finally again upgrade to Win 10 Pro. Now I cannot backup as I get an error"an error prevented backup from creating a snapshot of the volumes on this computer. Also I seem to have 3 recovery partitions and 1 EFI system partition all on my C drive. I am almost sure this is causing the error. Also when I expand each recovery partition they show duplicates. When I open the customize backup for this computer it shows a recovery disc, 2 Local Disks and the C disk as well as the other drives on my PC. It seems like I have a big mess and do not where to turn. What shows in Disk Management and my choices in the WHS console do not match. Please anyone with any ideas is much appreciated.
