What about clouds? Has anybody tried that method?

I have thought about using a "cloud," but I worry that "it" might "blow away" in the big ol' cyber-sky...Really...I'm not sure I would trust them in the long run...but I know very little about them...?

External hard drives a cheap, small, and easy to use.  As long as you don't keep them plug in when not in use.  Store them in a fire proof chest or safe for extra protection. 

Hey to All!

As a method for storing/backing up data, i.e., JPGs, MPGs, MP3s, etc...What, if any, is the difference, quality wise, between a FLASH DRIVE and an EXTERNAL HARD DRIVE? e.g. longevity, does either allow for deterioration of the stored datea etc...
Any replies will be Very Much Appreciated. Best! 

Many Thanks, gwhh, for your idea!  K to you!

icloud gives you 50 gigs of storage for just $0.99 a month.

And Google drive gives you 15G free.
