Poor Man's File Synchronization using PowerShell

I developed the following Powershell function to help me synchronize code on my new servers:

function SynchronizeFolder([string]$source, [string]$destination, $recurse, $exclusions)
{
   if($source.tostring().endswith("\") -ne $true){$source = "$source\"}
   if($destination.tostring().endswith("\") -ne $true){$destination = "$destination\"}

   # Variables
   $child_items
   $destination_file
   $destination_folder
   $result

   # Folder exists?
   if((test-path $destination) -eq $false){$result = md $destination}

   # Build child items
   if($recurse)
   {
      $child_items = get-childitem $source -recurse
   }
   else
   {
      $child_items = get-childitem $source
   }

   foreach($child_item in $child_items)
   {
      $destination_file = $destination + $child_item.fullname.substring((get-item $source).fullname.length)      
      $destination_folder = $destination_file
      if($child_item.psiscontainer -eq $false){$destination_folder = $destination_folder.substring(0, $destination_folder.lastindexof("\")) + "\"}   

      if($child_item.psiscontainer -eq $true)
      {
         #folder
         if((test-path $destination_folder) -eq $false)
         {
            $result = md $destination_folder
            echo $destination_folder
         }
      }
      else
      {
         #file
         if((test-path $destination_file) -eq $true)
         {
             #exists
            if($child_item.lastwritetime -ne (get-item $destination_file).lastwritetime -or $child_item.length -ne (get-item $destination_file).length)
            {
               if($child_item.fullname -match $exclusions -eq $false)
               {
                  copy $child_item.fullname $destination_folder
                  echo $destination_file
               }
            }
         }
         else
         {
            #new
            if($child_item.fullname -match $exclusions -eq $false)
            {
               copy $child_item.fullname $destination_folder
               echo $destination_file
            }
         }      
      }
   }
}
