Agreed. Time Machine is a thing of beauty when you see it in action. After Tom helped my girlfriend recover some data files from a crashed Macbook hard disk, we vowed to make sure she had better backups. I got her a small USB external hard disk that she backs up to with Time Machine, and it's super effective.

I also had the option of making her Time Machine backup be a file on our Synology NAS, but we opted for the external drive because it was faster to backup and restore, and it has a better, faster, and more direct route to recovery if her hard disk goes completely down again.
