backintime-gnome binary package in Ubuntu Precise powerpc

 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.
