Virtual failover client running on an external hypervisor

A virtual failover client (VFC) running on a hypervisor can be managed by a Unitrends Recovery-Series or UEB appliance, and the appliance can be a backup system or replication target. The hypervisor must be an ESX or Hyper-V server. See the following topics for details:

Unitrends backup system managing a virtual failover client on an external hypervisor

The diagram below illustrates a Unitrends backup system managing a virtual failover client (VFC) on an external hypervisor. The appliance creates the VFC using system metadata acquired from an eligible backup or from the client itself. (For details, see About retrieving configuration data for a virtual failover client). After the VFC is created, it is continually updated with virtual restores of backups from the original client. (See Virtual restores for Windows instant recovery.)

If the original client fails, you can boot the VFC in live mode and use it to replace the original client. It can function as a temporary replacement until you recover the original client to new physical hardware. If the hypervisor has sufficient resources, the live VFC can replace the original client permanently.

Because the VFC resides on a hypervisor, it does not impact the appliance’s resources. It uses the hypervisor’s resources instead. The backup system managing the VFC can be a Recovery-Series or UEB appliance.

Unitrends replication target managing a virtual failover client on an external hypervisor

The diagram below illustrates a Unitrends replication target managing a virtual failover client (VFC) on an external hypervisor. The replication target creates the VFC using system metadata acquired from replicated backups for the original client. After the VFC is created, it is continually updated with virtual restores of replicated backups from the original client. (See Virtual restores for Windows instant recovery.)

If the original client fails, you can boot the VFC in live mode and use it to replace the original client. It can function as a temporary replacement until you recover the original client to new physical hardware. If the hypervisor has sufficient resources, the live VFC can replace the original client permanently.

Because the VFC resides on a hypervisor, it does not impact the appliance’s resources. It uses the hypervisor’s resources instead. The replication target managing the VFC can be a Recovery-Series or UEB appliance.
