With digital you need to follow the 3, 2, 1 rule for archiving.
Three copies on two different types of medium, with one copy stored off site. I go a little beyond and keep one copy on an external hard disk, then use two different brands and types of DVDs, finally back up the important photos using Jungledisk to web storage on Amazon’s S3 service.
I also have many photos printed on real photo paper, rather than use ink jets. Most Walgreens have Fuji Frontier photo processing machines that will take jpegs and make real prints that look great.
Bingo!!
