Back up all your ESXi hosts to a local directory.

  1. # Change this to where you would like your backups to go.
  2. # There is no versioning so backup theses backups with real backup software (e.g. on an SMB share).
  3. $backupDir = "c:\backups"
  4.  
  5. # Get just your ESXi hosts.
  6. $esxiHosts = Get-VMHost | Where { $_ | Get-View -Property Config | Where { $_.Config.Product.ProductLineId -eq "embeddedEsx" } }
  7.  
  8. # Back them all up.
  9. $esxiHosts | Foreach {
  10.         $fullPath = $backupDir + "\" + $_.Name
  11.         mkdir $fullPath -ea SilentlyContinue | Out-Null
  12.         Set-VMHostFirmware -VMHost $_ -BackupConfiguration -DestinationPath $fullPath
  13. }
