[ale] Backup large files to span DVDs

[Jim Kinney]

+1

I have CDs I burned 15+ years ago that are perfectly fine. They are stored in cool temps and away from UV light. I have a cd burned a year ago that sat near a window and is unreadable. It was a temp need so nothing was lost. Storage of burned optical media is the key to their longevity once the media quality is stable.
