Recently I have been working to back up all of our data that my wife and I have. From pictures to videos, copies of bills, and school documents, it seems that more of our valuables reside in digital form than on paper. I have a special hard drive that I replicate our entire of life onto. It seems we have taken more pictures (new baby) in the past two months than we have in the last few years. It's more important than ever to back these important documents up.
A few days ago I thought that maybe I was going overboard with backing our data up. One thing I focused on in particular was my phone. I live and die by that thing. I send emails, tweet, store/take photos and videos, and even blog from it! I make it a regular practice to plug it in and send my photos and data to multiple places a few times a week.
Today my security blanket (phone) crashed. Yes it's possible for the wonderful iPhone 4 to crash folks! Even with my obsessive backing up, I still managed to lose a fee texts, pictures, and songs. This just goes to show that you can't ever be too careful!
So make it a regular part of your life. Back up your data with inexpensive programs like iTunes and Carbonite. It may not seem worth it at the time, but you'll thank yourself when, and I do mean when, your hardware crashes.
