Speaking from experience - This isn't nearly as foolproof as one would hope. I used that process to back up my music collection in the early days and have discovered that optical media/drives aren't nearly as durable or compatible as one would hope. Years later, I'd found a large portion of my collection was unreadable by all but the original drive that wrote them. And several of the disks have suffered aging failures.
