test the DVDs in other PCs after you make them to
ensure they're readable. You can make additional copies at various intervals .. just for additional backups.

We have a burner already the only thing that I worried about burning images to the dvd was that the discs tend to degrade through out the years. I didn't want to lose all the images. Although I could burn the images on the dvd until i get a hdd. It wont' take me 5 years to get a ex. hdd.
