I'm running hybrid hyper-v backup (local NAS and remote Openstack storage).I can't find a way to do a file level restore, when I run the restore wizard the option is grayed out. When I navigate my backup storage and right click on a backup to do a "file level restore" I only see the avhdx files, not the content of my VM.
This video describes the restore process. Have you navigated in Backup Storage to Hyper-V Hosts, then to the Host, and then to the VM in question? From there, you should be able to right-click on the backup and select the file-level restore option and search for the files to restore.If that is the process you're having trouble with, then I would ask you open a support ticket from the Tools - Diagnostic toolbar option in CloudBerry Backup so the Support team can review the logs.
