Rob is correct, to the extent that DVD has been around. The only potential “catch” to that is that the medium hasn’t been in play long enough to establish its true stability and shef life.
But, going on a wing and a prayer, I use a backup hard drive(s) exclusively dedicated to holding resources for repurposing, etc. AND burn everything I even THINK I want to keep on DVDs as well.
Beyond that, I don’t know what more could be done to preserve against loss of resources/materials. I am at the point now where I have so much reserve resources stuff I am considering another set of HD/DVD backups to store off site in the event of some “ultimate” catastrophe. Past THAT kind of redundancy I probably would need to check with a shrink to see if I am becoming overly paranoid. 🙂
