<div class="footnote"> <strong>🔍 VUL licensing basics (Veeam Universal License):</strong> One VUL covers one workload instance (VM, physical server, workstation, NAS share, cloud instance) regardless of the backup source or target. This calculator provides an estimate based on typical instance mapping. For advanced scenarios (NAS capacity factor, multi-instance VMs) always consult Veeam licensing guide. <br> ⚡ <em>Protection with Veeam Data Platform – flexible, portable, and future-proof.</em> </div> </div>

This tool helps you estimate the number of VULs needed based on your workload types (VMs, physical servers, workstations, NAS/file shares). const el = document.getElementById(id)
