Back In Time: A Simple Backup Tool For Linux (GNOME & KDE4)

Tux, the Linux penguinImage via Wikipedia
Back In Time is a simple backup tool for Linux. The backup is done by taking snapshots of a specified set of directories and you only need to specify 3 things: where to save snapshots, what to backup and backup frequency.

It's creating multiple snapshots with only one stuff, so it saves a lot of hard disk space for you. At the same time, you could customize its auto-remove option. Back in time's restore function is also easy to use - choose a snapshot & choose folders from it, then hit "Restore", that's all ;)
