... The point is that a HDD can fail at any time and if the HDD with the Image fail, it's gone! The DVD-RW last a bit longer, just only need to store in an safe place...
The chances of your C: drive and another HDD failing at the same time are extremely small - to the point where it is not worth worrying about it.
I make a system image of my C: drive every week and store it on an external USB HDD.
This isn't necessarily true. One of the (two) major concerns when talking about data redundancy and backups is that a disaster may occur. For example, a few months ago there was a leak in my office building and rain water got in and soaked a lot of our things. Luckily our server room was unaffected but a fire, flood, disgruntled employee with a baseball bat, or any number of disasters can occur which can destroy all of your drives. For this reason it is extremely important to not only have drive redundancy but also make full backups and store them remotely. Generally you can either use a tape drive of some kind or you can pay someone (like Iron Mountain for example) to keep stuff like that for you. In the future it may become more viable to buy space on remote servers (right now it's expensive and the service generally sucks). That would probably be the best choice, since even if your backups are separated from the machines they mimic you might lose everything in a wide spread disaster like a hurricane. With remote storage on another company's servers you reduce the chances of that happening with a larger geographical separation of backup and original.
Point being, you should take your usb drive home with you if you don't already. If there's a fire you lose both backup and computer.
