Searching I found solution in old documentation of PhoneGap (recent docs no have this information). To copy files just use copyTo method.

    window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, function(entry){
        var parent = document.getElementById('parent').value;
        parentEntry = new DirectoryEntry({fullPath: parent});

        // copy the file to a new directory and rename it
        entry.copyTo(parentEntry, "file.copy", function(entry){
            console.log("New Path: " + entry.fullPath);
        }, function(error){
            console.log(error.code);
        });

    }, null);
