Even though it isn't the currently best-rated program, I really like it because it is easy to set up and use.

Reflect backs up any partition or your whole hard drive to an external hard drive, CD or DVD.
It is easy to use, can do scheduled backups, and can restore your backup from a rescue CD.

I really recommend this firewall.
You NEED to install a good firewall (and disable that windows thing)
