WD 4TB My Book system back up problem

i have a WD 4TB My Book  to back up windows Server 2008. but backup process not complete with error msg. i just converted gpt format to use 4tb. why i m not able to backup my system in windows server 2008? i dont wanna use wd smartware. i really wanna use windows system backup with backup and restore option. please help.

Is Windows Server 2008 listed as one of the recognized OSs for this drive? That is probably the problem.


I’m trying the same for Win8.1 and can’t figure out how to accomplish this task.

A system backup that can be booted from My Book was my expectation, hope there is a way
