NovaBACKUP Business Essentials (B.E.) v19.3.x and newer (versions older than 19.3 did not contain a "Recover Previous" function in the Virtual Dashboard to utilize).
There is a "Recover Previous" (basically a way to import prior backups to list them) function to utilize for Virtual Dashboard (AVD) backups. If your system does not work anymore and you have to set up a new system with a fresh installed Windows and NBK B.E., you will see an empty Virtual Dashboard when you first load it, and it will ask you to add Hypervisor, you can click in the black space on the right.
You can restore from the old backups, by using the Recover Previous button at the bottom right of the Virtual Dashboard (AVD) dialog.
First, add the Hyper-V and/or VMware server to the new installed NovaBACKUP (NBK).
Open Virtual Dashboard (VD) and add the Hyper-V/VMware host.
For restoring from your external disk open the Virtual Dashboard (VD) and click on the blue button at bottom right hand. If you open the VD for the first time after installation you will see the screen as shown in Image 1:
