Hddbackup is a simple backup solution. It is not intended to compete with advanced solutions like Backuppc or Bacula. The software is implemented as a Python script using rsync, ssh, tar, gzip/bzip2/xz, and gpg. It is based on cdbkup, but all the CD-specific parts have been removed. It has been ported from Pearl to Python, new features have been added, and various bugs have been fixed.
