How to protect your virtual environment
My experience is that a product should always target a specific market. Trying to cover everything brings a lot of complexity and impacts usability - SMB organizations typically have less than 300 VMs and less than 25TB storage. This leads to one of the first things to keep in mind about backup. You need to consider the infrastructure - the size and topology. You need to choose the right backup tool and the right environment, based on the hypervisor vendors and size (VMs and data). One of the most important questions is how often you make backups and how often you have to store and archive them. Customers will refer to this as the RPO (Recovery Point Objective). If you have no legal requirements for retention and archiving, you should apply the 3-2-1 rule as a minimum standard.
