Yes, I should have mentioned about storing the backup somewhere else, I thought it was implicit. :-) I did not not know about the temporary nature of RW, thanks for mentioning that. I know nothing about dvd yet execpt that that they hold a lot of data (although much smaller than modern disks) and come in different flavors. I have a lot of reading to do... My experience with CD was different than your's -- of CDs I wrote 4 years ago, I have found about 20% unreadable. So I was worried about dvds. The CDs are name brand (Fujifilm). I wonder if the CDwriter used has an effect on longevity?
