Most advanced backup tools includes an option called "sector by sector". Does this option have to be checked when I backup system partition (an image)? I mean.. In case of HDD failure I have system image and I can easily restore my system on another HDD. Then, if needed, copy backuped data / files from another backup.
I do want to understand when and in which cases the "sector by sector" option is a must to check.
I have read the "possible duplicate question" and I understand that the option allows for backing up the disk in a way that allows accessing deleted / not wiped files. I asked my question in context of restoring system from image backup. I mean.. I want to know, if the "sector by sector" option influence in any way the possibility of restoring system (do windows files have to be in specific place / on specific sectors).
