-- How to resolve the following ReliableDR Unitrends Backup job error: "Failed to obtain the VM generation number."


ReliableDR Unitrends Backup jobs Agent is not installed on the server hosting the VMs



To explain how to resolve the following error when performing a ReliableDR Unitrends Backup job using a Hyper-V server:  “Failed to obtain the VM generation number.”


To resolve this issue, you must install Unitrends Windows agent release 8.0 or higher on the server hosting the original VM.  Although you can perform ReliableDR Unitrends Backup jobs for Hyper-V VMs using backups run with an earlier agent release, 8.0 or higher must be installed on the Hyper-V server for the appliance performing the instant recovery to retrieve the generation number for the VM.  If agent release 8.0 or higher has already been installed on the server hosting the VMs, you must refresh the list of VMs in the backup window of the appliance.  Use the following procedure:

1. Select the applicable Hyper-V application in the Navigation pane.

2. Click Backup in the Main Menu.

3.  Click the refresh button in the lower right corner of the screen.

You should now be able to run jobs successfully.
