We can never hear it too often. Make sure you back up your important files... Especially photographs. I'll go one further today... photographs deserve a second back up. Sort of a back up to the back up. I learned my lesson the hard way. I have about 50,000 on a hard drive that I cannot access. (Circa 2009.) It's in a safe place, waiting until I can afford to send it to a recovery service (estimated at $3,000) and even then it's not a guarantee I'll get my pictures back. Living in a digital world is wonderful... and accessible. But you have to set up a system to back up your data. Cloud computing is a fairly new concept for us but I love it. It makes life so much easier. But you have to remember to use it.
