And this is where having Optical Discs help. As part of my project, I’ve found backups from as far back as ’97, and as a result, recovered data that I’d lost by ’99. That includes an update to a book that can no longer be found on the Internet, and all the code for a Shareware program I wrote in ’96/97. The 3-2-1 rule says you should have at least 3 copies of your data, including two on different types of media, and a 3rd copy off-site. Zane
