google script: File class is not defined

I'm trying to make my google docs script create a backup copy of the file each time I open it.
To make a copy I write

var name = File.getName();
var filecopy = File.makeCopy(name + " backup");

But it won't recognize the File class. Although it knows DocsList. How do I make it work or make a copy of the file another way?

GAS permits to call class methods or instance only native classes (Object, String, etc), own classes or Google Services (DocList, SpreadsheetApp, etc). Other classes like File, Folder, Spreadsheet, Range, etc are accessible and instanceable only via calling the services functions, for example, DocsList.getFileById("..."); returns the File class instance.

The following function copies a file having the srcFileID ID to a new file with the name stored in the dstFileName parameter.

function testCopy(srcFileID, dstFileName) {
  var srcFile = DocsList.getFileById(srcFileID);
  srcFile.makeCopy(dstFileName);
}

You cannot use the File class that way. Use something on these lines

var file = DocsList.getFileById(ID) ; // you can use DocsList.find or DocsList.create 
var filecopy = file.makeCopy();
