Roaming Profiles

Afternoon,

Our current environment uses redirected folders for all our users and so we can make it easier for people to hot desk/log in from home using a VDI we want to switch to roaming profiles, we are however keen to avoid the long login times that are likely when it syncs (Our company's brass are quite particular about an 'open IT' set up - there are very little restrictions on our PC's/firewalls so they can browse facebook etc and also plug smart phones into charge - this inevitably results in people syncing photos)

What I'm currently looking into is having a split between folder redirects (photos and anything else likely to use a lot of space) and then having all their settings and documents on a roaming profile - this should sort most of the problems however, I'm unsure of any ways to pull the info down from the file server which houses their current redirected data and place it onto their local machines to then be synced as a roaming profile (other than going round each and every PC and copying it manually which will simply take too long)

Would anyone have any suggestions on how we could make this work?

Thanks.
