Description: The ‘Host Failback’ is a critical process in the management of virtualized infrastructures, especially in environments utilizing virtualization platforms. This term refers to the action of restoring a system or virtual machine to its primary host after a failover event has occurred. During a failure, virtual machines may be moved to a secondary host to ensure service continuity. Once the issue is resolved and the primary host is operational again, it is essential for the virtual machines to return to their original location to optimize performance and resource management. This process not only ensures that workloads run on the most suitable hardware but also maintains consistency in infrastructure management. Host failback is an integral part of disaster recovery and high availability strategies, as it minimizes downtime and maximizes operational efficiency. This process is managed through tools and features that allow administrators to perform the transition smoothly and in a controlled manner, ensuring that virtual machines are relocated without significant service interruptions.
