CD-RW is rewritable but is not as stable. Backing up to CD's at all is iffy so you should have more than one copy. Even two is not necessarily sufficient. I lost many years of journals when both CD backups developed cracks for no known reason. The length of time CD's last is also debatable, anywhere from no time to a few years. Nowadays I back up to two external hard-drives, a collection of flash-drives and online at Mozy. Occasionally I'll throw something on a CD or DVD but I wouldn't make that my main back up. I think it's important to choose more than one option. Spread your important files around for security. The price of external storage has dropped so dramatically in the past couple of years, you might consider it. -- JL JLog - simple computer technology for genealogists http://www3.telus.net/Jgen/jlog.html Patricia wrote: > Could someone please remind me the difference between CD-R and CD-RW and which one I should use to do a backup of my F/H program > Many thanks > Pat > -------------------------------------- > Having trouble with your subscription?
