If i lose the entire hyperv server, how to get things back ? my guess is to setup another hyperv server with same name as the previous one, re-download the client and use the powershell script to get my vhdx back. Correct ?
tried that but the client that I download is not “hyperv client” so no ps script onboard 
I manualy download hyperv client, try to reconnect it to my server using the same computer name / pw than my original hyper v host but it doesn’t restore :
PS C:\Program Files\UrBackup> .\hyperv_list_backups.ps1 -VmName my.supervm.com -username admin
Please enter the password for admin...: ***********
