Networker Exchange 2016 BBB using NMM 9.X

Hello ,

We are currently backing up exchange 2016 environment in our Networker 9.X datazone .

We use only Data domain for this backup and that is the best storage we prefer .but we have a problem especially on the charging the incremental data because of the fact that the levels are different in BBB setup as the resulting saveset for incremental using BBB will always be a level full that will also include the overall full backup size of the data . Lets say if the full backup runs tonight and the size is 20 TB and next day when an incremental backup runs with the BBB the backup saveset will be level full and the size would be around 20.2TB where the .2 TB is the change rate which can be considered as the incremental backup size but we are not sure it is going to be accurate to calculate in that way to charge and DPA is also giving the same total (mminfo) size for the DAG and it is difficult to convince the customer on the charging front and i would like to get an accurate information on the incremental backup to get charged correctly . Any suggestions on the exchange and on backup server/reporting server will be really helpful and highly appreciated .

Best Regards

Karthik
