  Heh.  700 megabytes is *tiny*.  One of our customer's weekly full backup
consumes over 200 gigabytes, and they're a *small* company.  :-)

  "Best" is subjective.  For a small setup like that, I would recommend a
DDS-4 tape drive.  They are fast, solid, and not too expensive.

  If your budget is really tight, you could get away with Travan.  Travan
drives are a lot cheaper.  Tapes cost a lot more, though, so you start to
lose if you buy a lot of tapes.  Travan is rather slow, especially on reads.  
In my experience, Travan has more reliability problems than other formats.

  4.2.2, eh?  Neat.  ;-)  Do you mean 2.4.2?  If so, you really need to
update your kernel.  The early 2.4.x kernels had some rather serious
stability problems.  If you haven't installed any other Red Hat Errata
fixes, do that, too.
