    $destDirPath = "f:/xahbackup_${xDate}";

    $null = mkdir $destDirPath;

    echo "ssss---------------------------------------------------";
    Get-Date -Format "yyyy-MM-dd HH:mm";
    echo "Start backup xah website git";
    $xahWebGitBackupPath = Join-Path $destDirPath "xahweb_${xDate}.git.zip";
    $gitCommand = "git --git-dir='c:/Users/xah/web/.git/' archive -o '${xahWebGitBackupPath}' HEAD";
    Invoke-Expression $gitCommand;

            7z a (Join-Path $destDirPath "$_.7z") "c:/Users/xah/$_/";
        })
