I'm running a number of SBS2003 R2 premium servers with WSUS3, ISA2004 configured.
While checking out the capacity match between the backup media and the data to be backed up I'm noticing a significant difference between the used/free space obtained when clicking properties on, say, the D drive and the sum of all the individually reported top level folder sizes (I just use properties and look at the size of each folder in explorer).
On one server the drive properties report Capacity 111GB, Used 35.4GB and Free 75.8GB, all consistent so far. But if I select all top level folders (including system and hidden) and look at properties and size it shows 24.2GB used. Thats a big difference (at least in my little networks)
Can anyone tell me why this is, I think my backup hardware is under provisioned, but I thought a DAT72 drive should have been OK since we only recently upgraded from the DAT40 when we changed to SBS2003. I've got a cold sweet forming since my customer isn't known for shelling out very often !!!
Hope someone can help . . .
