Capacity-based licensing for CDP
Licensing collects the total number of front-end terabytes protected by NetBackup. The front-end data size for CDP backup is nearly same as consumed storage size on ESX datastore by the VMs.
The nbdeployutil utility reports data usage for the VMs. Following rules are applied to report data size:
Calculate the total number of bytes written during backup (X) and the VM size from ESX datastore (Y). The reported size is the smaller value of X and Y.
If different policies use the same virtual machine, the policy with higher data size is accounted.
If VADP and CDP policy protects the same VM then you are charged only once, with the higher size.
Administrator can use the following steps to verify the data size reported by licensing:
Verify the size occupied by the VMs on ESX datastore on the vCenter. Navigate to Datastore > Files > VM, the Size column shows the size occupied on datastore.
Verify the bytes written during backup for same VM.
Calculate the minimum of the above two values.
