When to use a CD for backup
Our regular listeners hear us talk about this subject often, but it bears repeating as much as we can talk about it for your data's safety and your sanity. Backing up to CD's is a multi-step process and all the steps need to be followed for it to go right.
CD's work great for archiving data that won't change. This includes pictures, music, your finished novel, etc. CD's should only be burned ONE time. CD-R's have the capability of being written to many times, but this also increases the likelihood of problems with the CD. Burn them once and store them in a safe place.
