Déjà Vu offers an intuitive and reliable way to back up your data. It's a preference pane that lives in your System Preferences, and it allows you to schedule unattended backups of important folders, or even your entire system.
Backup any number of individual folders separately. Perhaps you only want to backup your Home folder or your Documents folder on a daily basis, while making a full backup of your hard drive on a weekly basis. Déjà Vu gives you just this kind of flexibility.
