When you move  a file like code

        public function Movetobackup($file){
            rename($this->HOME.$this->download.$file, $this->HOME.$this->backup.$file);//TODO BEFORE UPLOAD UNCOMMENT
            if($this->debug){print "!!! $file moved!!!";} 
            //touch($dest, filemtime($src));//reset of the time of a file 
        }
then wil i lost te file when php has not access to the dest dir.
so i think it is a important issiue

Test script:
---------------
class classe1  {
     private $dir = "";
 public function Movetobackup($file,$dir){
            rename($this->dir.$file, $dir.$file);//TODO BEFORE UPLOAD UNCOMMENT
            if($this->debug){print "!!! $file moved!!!";} 
            //touch($dest, filemtime($src));//reset of the time of a file 
 }
}

$test = new classe1();
$test->move("myfile.txt","/newdir");
