MBR partition types are supported and can be backed up via Bare Metal.
However, you can protect clients with GPT disks (GUID partition type) using the Windows integrated bare metal recovery feature, a form of hot bare metal protection added in the 7.4 release. For details, see Windows integrated bare metal recovery in the Unitrends Administrator's Guide.
