Fault Tolerance

VMware fault tolerance provides uninterrupted availability by eliminating the need to restart a virtual machine by copying a functional virtual machine to a second ESX/ESXi host while making sure that both virtual machines are synchronized, so that if the ESX/ESXi that is hosting the primary virtual machine goes down, the secondary virtual machine takes over.

Zerto does not support fault tolerance for machines in a VPG, nor for a Virtual Replication Appliance (VRA).
