I understand the concepts of both roaming profiles and folder redirection and have used both separately before. I am about to set up a network from scratch and would ideally like to use both for the following reasons primarily

• Roaming profiles allow users to log on to any machine and have their profile
• Redirected profiles allow users to have their My Documents and Desktop etc backed up without the need to log off at the end of the day. The servers can run their backups overnight and there are no missing files due to the user not logging off.
• Redirected profiles largely alleviate the slow log in times caused by large profiles.

My question is if some of the folders are redirected and therefore not part of the roaming profile what happens on machines which truly roam (i.e. laptops)?

If there's offline files or a cache does this mean that the problem whereby a user has to log off comes back?

By having them both enabled, is there any duplication i.e. if I have a users$ share and a profiles$ share would I have Desktop twice for example?
