The standard snapshot mechanism suspends all processes while the memory is saved. The writable disk image swap occurs in the hypervisor and is transparent to the VM. Data Protection adds the ability to snapshot on demand for backups and signal aware programs in the VM to save state before being suspended. WRT shapshot integrity, I don't think the latter really adds much, but YMMV.
