                //delete zip file
                exec(deleteFolder+".zip", function(){
                    //

                console.log("Archive ID", data.archiveId);

            res.send("ok");
        });


    }

    exec(mongodump +' && ' +zip+' &&' + deleteFolder, puts);
};

Doesn't seem like mongoose dependency is necessary here?
