I currently only want to back up important files like (photos, music, documents) in case of a hard drive failure. I would NOT want a complete restore, but rather do a clean install with a new hard drive in the event of a hard drive or motherboard failure. I periodically back these files to DVD. I also don't want a mirrored raid or use any cloud storage. Making backups to DVD creates a lot of DVD's. What is your thoughts on having a second internal hard drive just for backing up my important files to instead of using DVD's?
