Backing Up AD Domain Controller Using Windows Server Backup

Powershell Backup Script

Back up a domain controller using PowerShell. To keep multiple levels of AD backup copies, we will store each backup copy in a separate directory with the date of backup creation as the folder name.

Import-Module ServerManager
[string]$date = get-date -f 'yyyy-MM-dd'
$path=”\\mun-back1\backup\dc1\”
$TargetUNC=$path+$date
$TestTargetUNC= Test-Path -Path $TargetUNC
if (!($TestTargetUNC)){
New-Item -Path $TargetUNC -ItemType directory
}
$WBadmin_cmd = "wbadmin.exe START BACKUP -backupTarget:$TargetUNC -systemState -noverify -vssCopy -quiet"
Invoke-Expression $WBadmin_cmd
