In DPA 6.1.2 I have created a Backup Chargeback policy that specifies a Base Size of 150 GB and a Base Cost of 75.  I applied this policy to a client that has a backup size of 3 GB and when I run the report Chargeback Details by Client for the last month it shows a backup cost of $225.00 instead of $75.00.  Any ideas as to where the problem is at?  Thanks
