NetApp has a nasty way of dealing with the license for the product's on-premises virtual NetApp appliance that you need in your whole architecture, and it is not directly linked to NetApp Cloud Backup. It is not a feature that I want to change in NetApp Cloud Backup because the cloud backup service is architectured in a way that makes it available to users, so it looks pretty good to me. When you go to the other side, you can see what you want to have on-premises for the main side in order to have backup in the cloud via NetApp Cloud Backup. With the on-premises part, you need to have either a physical NetApp or a virtual NetApp. You only have two options for primary storage from the network. In the physical cases, it is pretty straightforward as you have pricing and something like a grid with your NetApp. The sales representatives explain how much it will cost you to have some physical NetApp storage based on performance, types, and so on. The support contracts are for three or five years. When it comes to the virtual NetApp, you can run on top of an existing VMware tool or a recent cluster; it gets nasty because they do not let you change the licensed server. Once you deploy a virtual NetApp with a licensed server that you have on-premises, you migrate off from that, but NetApp does not let you change the licensed server, which should be really simple.
