Both of them have to ensure you can make a consistent snapshot. Doing that means you've got to be able to define a single "point" at which the snapshot is made and is internally self-consistent. That in both cases tends to mean you've got to ensure nothing occurs which pees on the image while you are making that snapshot (such as outstanding O_DIRECT I/O to user pages).
