Do you need to recover files individually? If so, then image backup (at
least on its own) won't be a good option. One thing you could do is tar up
chunks (maybe a million files) and archive/backup those chunks. Keep a
catalog (hopefully a database with indexes) of which files are in which tar 
balls, and
then when you go to restore you only have to recover 1/80000 of your data
to get one file.
