Back it up!
I am using online storage services more and more these days, after the big incident I had last month when I lost a bunch of really important files that I could not get back 
Now I back things up in as many places as possbile, as often as possible.
You see people saying it all the time but don’t really pay attention, at least I didn’t. But now I am one of those people saying “BACK IT UP, DUMMY!”.
