What’s NFR?
A Not-For-Resale (NFR) license is a license that can be used in a test environment or home lab for product demos and trainings. NFR for Veeam solutions is a cut above most regular trial keys because it has a 1-year retention period, instead of just 30 days.
Here’s how you can get a free Veeam NFR license key.
