I mean, the error message says exactly what the problem is and what to do about it - restore the data to a bigger target disk, because the data just isn't fitting. The second thing he posted is some random irrelevance that has *nothing* to do with the actual reported error code.
Incidentally, the second suggestion in the original error message, -ntexact, is only for a specific case where the end user is ABSOLUTELY SURE the target is the same size as the original source and so the data can be made to fit even there was zero free space in the source. However, given how badly NTFS behaves when the free space gets under about 15% that's always the wrong thing to do, and you really need a bigger disk just as the error says.
