I am working in Manufacturing Execution Systems area and the internal sites are spread around the globe on all continents; speed does matter, there are dozens of places hundreds of kilometers away from a place with Gigabit Internet (for WAN). Taking backups off site is faster by physically shipping hard drives than copying over the WAN, I don't like any large software. In one place in Africa driving to another site 3 hours away gets network speed 10x better, so we do this from time to time.
