When was the last time you stopped and thought about all the cool stuff you keep on your computer--quilt photos, family photos, software you've downloaded, tax files, business files, and so on--and what the consequences would be if you lost it all?
Two of my friends recently had major issues with their computers that rendered their data files inaccessible. They were able to recover all or most of them, which was good, because some of those files were irreplaceable.
Folks, if you haven't backed up your files lately, get yourself an external hard drive or some CDs and take the time to back them up. Make it a habit to do a back up at regular intervals, depending on how often you use your computer. I need to make myself do this as well. I checked, and the last time I backed up my hard drive was last November, so I sat down this evening and did it. I have an external hard drive, so I click and drag everything I want to keep, and it didn't take nearly as long as I anticipated.
Don't procrastinate--do it now.
