A perpetual license allows you to use NAKIVO Backup & Replication forever. For VMware, the product is licensed per physical CPU socket for each ESXi server on which you back up or replicate VMs. For AWS EC2, the product is licensed per instance that you back up or replicate.
Pro and Enterprise editions work with any edition of VMware vSphere, and you can purchase any number of socket licenses.
Essentials editions enable you to protect small environments at an even more affordable price, but are limited to 2, 4, and 6 socket license sets per organization. The Essentials editions work with any edition of VMware vSphere: Essentials, Essentials Plus, Standard, Enterprise, and Enterprise Plus.
