That is _exactly_ what I'm doing.  When I was deciding on a backup 
mechanism (tapes vs DVD), DVD seemed a lot cheaper.  I guess I just 
assumed that the tape way, tar.gz, would have been appropriate.  I guess 
it's not really a good idea in this case.

OK, I'll look into afio.  Thanks for the info.

That sounds like a good idea also.  Actually, I would like to read the 
whole article.  Do you know if it is possible to buy the issue in PDF 
somewhere?  If not, I will just buy a hard copy.

Thanks a lot for the info.
