If you configure RAR properly it will create a set of files that can be 
used to rebuild the archive.  You can set the amount of rebuild files so 
if you have a set of files that are corrupted, you can do a repair.

It can split large files into more manageable parts or smaller sizes if 
there is a corrupted DVD where you lose part of the DVD, you can still 
recover all of the data.

You could make a tar.gz image of your data and then rar the data into 
smaller files to be saved.  Many options abound.

RAR is not free but shareware http://www.rarlab.com/
