Back In Time is a simple backup tool for Linux inspired from "flyback project" and "TimeVault". The backup is done by taking snapshots of a specified set of directories.
Currently there are two GUI available: Gnome and KDE 4 (>= 4.1).
All you have to do is configure:
* Where to save snapshot
* What directories to backup
* When backup should be done (manual, every hour, every day, every week, every month)
