Do you have precious pictures, music, and documents on your computer? I can’t tell you how many times people have asked me to help recover data from their failed hard drive. Consider this advice your data insurance plan. I think most of us would prefer to have a $300 fail-proof plan (on 1 terabyte of data, or as little as $50 if you only have a few gigabytes) compared to the $1000 to $3000 data recovery cost – with no guarantee – if your drive dies. I will use my own experience in buying a new drive, enclosure, and testing software to illuminate some of the things you should consider when it comes to backing up your data. I’m almost as wet behind the ears as the next guy when it comes to home-user backup strategies, so don’t take this as gospel advice. Please chime in with your own backup strategy.
