If you have multiple usb sticks because they can break.... Do you also have a spare arranger, for if that breaks down...

If i was a gigging musician, i really would have a backup one, ready for gigging..
Because if you would be playing at a wedding, i could not live with myelf if there was no music, and my broken arranger was guilty for ruining a wedding... It would be my worse nightmare, having other people relying on me, and me failing them

But then i work for a millitary organisation, where we allways have atleast 2 backup plans
