Let me make one comment on that. To back up files of reasonable (<1GB) 
files, you can build a list of files which will fit on a single DVD (a 
series of lists actually), and backup the files to a DVD, either in ISO 
format or using the loopback mount to make an ext2 filesystem you can 
write to a DVD, or a tar, cpio, you get the idea. The tool to make the 
lists of files which will fit is "breaker" and is on 
www.tmr.com/~public/source for your enjoyment.

The other tool is dvdisaster, which builds software ECC for images you 
are going to burn. You can make DVDs with 3.3GB data + ECC on each DVD, 
or 4.4GB data per DVD and keep the ECC files separately, whatever 
pleases you.  The recovery mode does work, I used scissors to scratch a 
DVD with my initials, then recovered the data.

Both programs have enough documentation for most users.
