I have a single 1TB My Book Essential. I also own a single HP laptop with two HDD (C/F) as well as a Compaq laptop with a single C HDD and a Dell desktop computer with a single C HDD. I am trying to back each up and retain all three on the 1TB external device for recovery purposes. I am unable to find a way to so this.
Can someone provide “Detailed” instructions for this process and tell me how to verify each backup is complete and useable to recover a complete system HDD failure ?
I am not very literate in the processes so as much detail as possible would be appreciated.
