is a simple, easy-to-configure System Preference pane that helps you backup up your data to any directly attached or network attached drive, including optical media such.
Déjà Vu works in a fashion similar to Time Machine, Apple’s built-in backup software, but it offers many more configuration options, allowing you to select the volumes or folders you want to backup, choose whether you want those folder backed up daily, weekly, monthly, or manually, and lets you set the time when you want each of these backups to take place.
Beyond basic backups Déjà Vu also offers options for repairing volume permissions before a backup starts, can clone complete startup volumes and create versioned backups, and perform one-way synchronization of folders. The application’s only real weakness is that it cannot backup data if a user is not logged in.
