Back up your computer data.
Do it now, I'll wait.
Good. I am learning this lesson the hard way. My laptop began having trouble some months ago. It wouldn't shut down properly. But hey, it still connected to the Internet and I could still get some work done.
Then it stopped connecting to any network except my in-home wireless network. Well, that was problematic but as long as it was able to get online at home, everyone in my family had a computer to use and all was right with the world. It wouldn't let me access the wireless software properties to fix anything and I knew one day I'd have to call Tech Support to get it fixed, but for some reason, I thought we'd just uninstall and reinstall the wi-fi software, and I'd be good to go.
So I continued not backing anything up.
This past week, my laptop stopped connecting to the Internet. And I still couldn't access my wireless software. And it still wouldn't shut down properly. So I finally made the call to Tech Support. But did I back anything up before that call?
92 minutes later, after completely wiping my hard drive and reinstalling the operating system, my laptop runs like the day I pulled it out of the box.
Unfortunately, that's what my hard drive looks like, too. So not only is all my data gone, but now I've got several hours of re-configuration and customizing to get it back to where I like it.
So the moral here is back up your computer, kids. At least once a week.
You can purchase several commercial products to do this: Norton's Ghost is one of the better ones. Or you can go to Mozy and backup your stuff to an online server, if it's not too private.
Go to school on your Uncle Mark and start backing up your data.
Again, do it today.
