Cannot backup VMs with unsupported devices on ESXi 5.5 host (HW compatible with ver 10)
To inform customers that VMware Virtual Machines with VM Hardware Version 10 (vmx-10) with some Virtual Hardware Controllers might not be backed up.
VMware introduced new Virtual Hardware Controllers with vSphere 5.5 and VM Hardware Version 10. These controllers cannot be backed up as they are not recognized by Unitrends 7.3 and older. The primary new controller type not recognized is the new SATA controller. See the attached document, 18551.v2.KB.pdf for detailed information.
