I have set up a new HP DL380 Gen8 server with windows server 2012.
This server has a C-drive of 1,9 TB.
I've set up 3 Hyper-V VMs on this server.
When I try to do a windows backup to a external harddrive (2TB), I get the error:
"Backup of volume C: has failed. The drive cannot find the sector requested."
The server has 8 x 300GB harddrive in one RAID5 volume.
