Most likely I can get your stuff back, but lets stay in the present right now.
We are talking about two different things. You have backed up your OS (Vista). In case you get a bad virus or your hard drive fails or someone does something that they should not and you cant boot the OS, you use the Macrium Image.
But not all problems are that big, you may just want your emails back or a pic or a letter from someone special, then you use the back up on Karens. We dont use a fire hose to put out a match. You understand what I mean? The back up on your hard drive, now is for emergencies when you cant boot or the OS has a major virus or problem.
We back up your stuff, now in case you lose your email or pic etc.
If you want your email back, use shadow explorer, its free.

EDIT:Would you really replace your entire OS with an image if all you want back is an email. The bigger the change you make, the higher the probability of problems.
2nd Edit:Your back up now is for your OS. If you could not boot, what would you do if you did not have a back up of Vista. What would you do if your hard drive fails. We are talking about 2 different types of back ups.
Vista for emergencies and your stuff to get back your email etc. You may or may not know, some members had to go out and by a Vista/Seven DVD because they lost Vista and had no back up on Macrium
