Back In Time is a simple backup system 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)
