System image copies disk sectors?
I'm curious about system images that Windows Backup makes.
When making a system image, does Windows 7 make a disk image by copying the files on the drive or does it copy the disk sector-by-sector verbatim, including the free space?
Hypothetically, if I had a failing hard disk drive that I made a system image of and restored that image to a good hard disk drive, could I then scan the good drive sector-by-sector to recover any missing files from it?

Hi,
Thanks for the post!
Q1: When making a system image, does Windows 7 make a disk image by copying the files on the drive or does it copy the disk sector-by-sector verbatim,
including the free space?
The process of backup is very complicated, many data was compressed. The backup is for data, not for the space.
Q2: if I had a failing hard disk drive that I made a system image of and restored that image to a good hard disk drive, could I then scan
the good drive sector-by-sector to recover any missing files from it?
If you backup a damaged drive (depends on different situation) and restore from that, the system could be restored to that damaged one. You can use
System File Checker to check if there’s any damaged system file and repair the system in WinRE.
Please refer to :
Wikipedia define Backup
