If you've ever lost something as a result of file corruption or hardware failure, you know how painful that can be. To pour salt in the wound, "friends and family" remind you how you should have backed up. Creating backups is a task that's easily put off, and like insurance, makes you question whether going out of your way regularly to safeguard against a potential disaster is really necessary. What are the chances of something happening to you right now?
I have an 80gb drive filled with a number of projects I completed while in college. Sure, I had plenty of opportunities to back up, but given my busy schedule, I hadn't taken the chance to create a back up of my information. Furthermore, I owned a couple hard drives that were a few years older and running okay. One thing I learned from this experience is that you can't possibly take into account all variables to determine probability of an accident.
I lost everything on that drive and still have it tucked away in an anti-static bag for that slim hope I find an opportunity to recover it some day 
I discovered KeepSafe while here at Stardock and it's one of the few apps I couldn't live without. Go through a simple setup choosing file extensions and/or directories to have KeepSafe monitor, tweak the settings a little (save a copy to network directories, etc), and that's all. KeepSafe starts up automatically by default, runs in the system tray, and never bothers you. Take a couple minutes for the setup, and never be concerned with the redundant frustration of backing up again!
I can finally relax, because the worst part of file corruption and hardware failure means simply reinstalling or obtaining an RMA.
The poor 80gb hdd in my closet will sit alone.
Update: This has saved me three times now while working on some gadgets for MyColors. KeepSafe, I sing your praises!
