If you were to add Applications Integration to any of the Virtual machines, you would need additional On-Line extension licenses
If you were planning on using Granular Recovery Extension (GRE), each server that is using this would require a GRE license
You need enough singe-drive licenses for the number of drives you are going to be running simutaneously. If you are going to be using a File Library or a Virtual Tape library, you need Advanced Backup to Disk licenses based on the total possible capacity of the disk device
We are not able to give you prices (mostly because I am totally clueless), this should be done by talking to a pre-sales specialist
