In one of my presentations for the VeeamON conference, titled The Quest for the Ultimate Backup Storage Architecture, I will explain how a tiered approach to data protection is the best solution to have an effective protection in place, and I will describe the different layers of data protection that can be applied to a production environment, and the layer I thought about for the most of the time was Storage Snapshots. After some thinking, I labeled it as a Tier-0 level, with specific pros and cons that should be carefully evaluated to properly use them in a data protection scenario.
