In accordance with a japanese itil-like security measures we are going to be required to backup at least 6 of our workstations, but could be as many as 30. We're not yet on an AD server, we will be soon though... I was thinking about having roaming profiles and then backing up those profiles to a tape drive. Our security admin thinks that there's going to be too much data and we'll need a NAS device.
I think backing up workstations is a little overkill and going to be money out the window that should go in our pockets

Do any of your companies do this? I was just wondering what the most cost efficient thing would be....
