Definitely, but f2thak's reported issue is that he's unable to install anything after restoring the backup. Now, given the posts I've seen from him in other threads, I'm more inclined to believe that he's stuffed it up somehow himself than that the backup app is inherently faulty, but I'd still be interested in knowing exactly where the issue lies.
Yes, it also made it impossible for me to install other certain apps which were saying "Not Installable" in the app manager due to missing dependencies.
