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 common framework for Back In Time. You need to choose a suitable front-end for your desktop environment, like backintime-gnome or backintime-kde.
