I noticed this on the package overview for WH 4.0 new accounts and was curious so I did a search and found this at Wikipedia. http://en.wikipedia.org/wiki/Continuous_data_protection

The article mentions that the term is often used in different ways and was wondering what it actually means in regards to a WH 4.0 account. Does it really mean that on packages that it is offered on that any change is instantly written to another server also? Would that include email and databases also? It seems like a pretty cool feature but I still don't know that I want to give up making my own backups.
