or get what i have. I use a backup box that all my computer devices plug into. Whenever we lose house power a signal goes off, (a beeping) letting me know I have (it stores electricity) 30 seconds before IT runs out of juice! I have used it occasionally during power outages, and I get to save whatever I'm currently working on and shut down my computer, during that time. No more lost files due to blackouts. It costs about $80 for this unit, but it's well worth it. It let me save my files three times in the last 9 months so it has more than paid for itself. And for $80 it's not a bad investment
