So, when you boot with the ISO media, you will be able to restore the entire system volume through that wizard. While it is technically not a full BMR (that would require ALL volumes according to the BMR definition but...
) you would fully recover your OS. After that, and reboot after the recovery, you will be able to recover the specific folders that you are also protecting.
To conclude: Is it a BMR, not according to the definition but you will be doing a volume restore of your system volume and therefore get the OS back to a state as it was at the time of backup, and then you can recover whatever folder afterwards from the folders you chose on the other volumes.
Does this makes sense?
