如何使用 wbadmin 在備份中包含 HyperV 的“主機組件”？

我正在嘗試設置一個腳本來僅使用 WBADMIN 執行我的虛擬機的備份，我已經能夠使用新的 -HyperV 開關備份所有虛擬機，但是我也想備份 HyperV主機組件。有沒有人有這方面的經驗或者可以指點我一些文件（微軟忽略了這個新的 -HyperV 開關）

如果您有興趣，這是我的 powershell 腳本：

#Constant Variables
$Day = Get-Date
$Day = $Day.DayOfWeek
$Date = Get-Date -format hhmmddMMyyyy
$Server = hostname

#Set Paths
$BackupPath =  "\\backup\Backups\" + $Server + "\" +$Day
$LogPath = "\\backup\Backups\" + $Server + "\Logs\" + $Date +".txt"


# SELECT Virtual Machines
$VMList = $null
$VMs = Get-VM | Select-Object VMId
for ($i = 0 ; $i -lt $VMs.length ; $i++) {
   $VMList = $VMList + '"' + $VMs[$i].VMId + '"' +","
}
$VMList =  $VMList.Substring(0,$VMList.Length - 1)

#Run Backup
WBADMIN START BACKUP -backupTarget:$BackupPath -hyperv:$VMList -Quiet

所以我終於發現你需要放棄 WBADMIN 並開始在 powershell 中使用 WBbackup CMDLETS，這就是你如何做到的

#Constant Variables
$Day = Get-Date
  #Use this for Backups in Evening
   $Day = ($Day.AddDays(1)).DayOfWeek

   #Use this for Backups in the Morning
   #$Day = $Day.DayOfWeek

$Date = Get-Date -format hhmmddMMyyyy
$Server = hostname
$Target = '\\backup\backups\'+$Server+'\'+$Day
$VirtualMachines = Get-WBVirtualMachine


$DailyFullWB = New-WBPolicy
$BackupTarget = New-WBBackupTarget -NetworkPath $Target
Set-WBPolicy -Policy $DailyFullWB
Add-WBBackupTarget -Policy $DailyFullWB -Target $BackupTarget -Force
Add-WBVirtualMachine -Policy $DailyFullWB -VirtualMachine $VirtualMachines
Start-WBBackup -Policy $DailyFullWB -AllowDeleteOldBackups -Force
