I use BackUpMyPC by Stomp. This product is actually a Veritas program resold by Stomp. I use it every day to backup about 4 GB of data to DVD+RW. Before I got the DVD, I backed up to CD-RW.
I only backup data files. If something goes wrong with an application, I would just re-install it. With todays huge hard drives, it would take forever to backup everything.
I have not had the need to recover anything yet.
I don't use it on a laptop, but don't know what difference that would make.
I have also contacted Stomp for technical support via email and got a very quick response. This was when I needed to move the application from my old PC to my new one, and had lost the original download. I learned to back up that download manually.

They let you re-download the app three times, I think, in a one year period.
