CloudBacko Pro : v4.1 or above
When performing a VMware guest VM backup in VDDK mode on VMware vCenter / ESXi version 5.0.x, 5.1.x, or 5.5.x, the following error message is received in the backup report:

This issue occurs because the VMware VDDK 7 API used in CloudBacko Pro v4.1 or above, are not supported by VMware vCenter / ESXi version 5.0.x, v5.1.x, and v5.5.x for backup in VDDK mode.
