		 Having hard copy back ups is really a good idea. Drives like the hard drive of a PC and of an external can fail and you lose the data.  Unless you want to pay a company to try and recover it and that will cost you and then you may not get it all. 
 
I just think they will be moving to only the larger disks for storage
