Alright people calm down here! When I get ticked I simply call the system a "mindless pc" or piece of...
The point is is that it does work! For multiple images there's a trick to that as far as the backup option in 7 or any other program of simply renaming the folder itself in order to see another image made which creates a brand new WindowsImageBackup folder of the exact same name. Adding a date like WindowsImageBackup_July 29 would prevent the automatic overwrite.
Moving images between drives also offsets the Windows information tucked away and can stall a restoration. That accounts for the restoration option while booted live not finding an image while the restoration option in the CP however can still use it to start it there.
With Macrium Reflect inbetween changing drive letters an image of Vista back in 2009 was seen as invalid following a swap around of RC installs. Acronic T.I. on the other hand was another 3rd party element that can still restore an image moved from one place to another once you browse to the main folder.
Different backup programs each have their advantages or disadvantages just like any other software type! You go by what works in your situation. Here the 7 option and Acronis do the job without problem. Acronis simply compresses images down in size and is able to mount images as a virtual C drive being a 3rd party full featured program you pay separately for.
