Back In Time
Simple backup system
Back In Time is a framework for rsync, diff and cron for the purpose of taking snapshots and backups of specified folders. It minimizes disk space use by taking a snapshot only if the directory has been changed, and hard links for unmodified files if it has. The user can schedule regular backups using cron.
This is the GNOME front-end for the backintime-common package. If you also install the package nautilus-actions, it can be integrated with the Nautilus file manager to provide context-menu options.
