How to Backup ESXi Configuration with PowerCLI

I have 2 ESXi Hosts without vCenter. For backup the ESXi configuration I used a PowerCLI script:

Connect-VIServer [2001:DB8::10]
Connect-VIServer [2001:DB8::11]
$esxhost = Get-VMHost
Get-VMHostFirmware -VMHost $esxhost -BackupConfiguration -DestinationPath C:\Backup

Change the IP Address with the address of yours ESXi hosts and set the DestinationPath according to your environment.

For restore the configuration use these commands:

Connect-VIServer [2001:DB8::10]
$esxhost = Get-VMHost
Set-VMHostFirmware -VMHost $esxhost -Restore -SourcePath C:\Backup\configBundle-[2001:DB8::10].tgz

Remember to put ESXi host in “Maintenance Mode” before restore the conf.
