Over the years, I like many others have used CDs or DVDs to backup files.  Of course as videos, pictures, VHDs, ISOs, etc get larger and larger... the limits of these technologies result in a number of headaches.  Recently I decided to switch to doing all of my backups on external HDs.  You can now easily get a 250GB external USB drive for about $100.  At this price, it becomes feasible IMO to simply backup to two of these HDs instead of using 50 or so DVDs.
