I think nobody has yet mentioned rdiff-backup. I have very good 
experiences with it. Easy to setup and control (only remember first to 
install the required packages, and I think rsync-devel was not mentioned 
but is required).

Rdiff-backup keeps up an exact copy of the source director(ies), plus it 
maintains a separate directory for deleted/changed items. With an 
appropriate command you can restore the source directory as it was at a 
given point of time. Very neat, and space-saving.
