As an IT professional I totally agree with this.

Long term local storage is a challenging problem. The best solution I've seen so far is multiple copies on high-quality DVD-R media, refreshed (meaning buying new media and burning new backups) at intervals to overcome the ravages of time.

I don't need that level of redundancy, so I maintain an offline hard drive backup plus a single DVD-R backup of certain critical data.
