If a Windows client that you are protecting with Windows instant recovery fails, you can temporarily replace it with the virtual failover client (VFC) by booting the VFC in live mode. Because virtual restores constantly update the VFC with the original client’s data, the VFC can immediately assume the role of the original client until you can recover it to new physical hardware. If the VFC resides on an external hypervisor, it can permanently replace the original client if the hypervisor has sufficient resources.
Note: About failed clients for which you have not created VFCs - If eligible backups for a client reside on a Unitrends backup system or replication target, the Untirends appliance can use these backups to create a VFC even after a client has failed. For details, see About retrieving configuration data for a virtual failover client.
The VFC in live mode is protected by the original client’s backup and archive schedules. However, it is no longer managed by the Unitrends appliance. Its status is Invalid, and virtual restores are no longer performed to the VFC.
This section provides instructions for booting a VFC in live mode and recommendations for steps to take after the VFC is live. See the following topics for details:
