I just made my first image of my system drive to an external drive. Is there any possible way to check if it is correct or has any glitches without having to restore my system drive with it? How do I know that it will really work fine when some day I will have to restore my system drive ? Also, when I did the backup, I notice that while creating the image other programs like spyware program had run on the background. After several hours of creating the image I got a message saying that the backup operation completed successfully. I am assuming that running other programs on the background will not cause a conflict with the backup operation. But I would like to make sure.
