We use a parent folder just under the server share point (often APPS) named with the product and version (MAS20045). On some newer systems, I have been inserting a Sage Folder between the Share and the parent folder. Within the parent folder, we have the MAS90 folder plus folders for year end, product updates and hot fixes, reports backup, documentation, notes, ect. We don't put anything in the MAS90 folder. Paperless data is usually put at the same level as the MAS parent folder. When we can, convenience items such as install CD copies and install images get stored in a separate Drive/Partition that does not get backed up.
