<P>
You want to back up as much as possible. The major exception
is software that can be easily reinstalled,<A NAME="tex2html51" HREF="footnode.html#3001"><IMG ALIGN=BOTTOM ALT="gif" SRC="./foot_motif.gif"></A> but even they may have configuration
files that it is important to back up, lest you need to do
all the work to configure them all over again. Another major
exception is the <tt>/proc</tt><A NAME="3089"> </A> filesystem; since that only
contains data that the kernel always generates automatically,
it is <em>never</em> a good idea to back it up. Expecially
the <tt>/proc/kcore</tt><A NAME="3091"> </A> file is unnecessary, since it is just
an image of your current physical memory; it's pretty large
as well.
<P>
Gray areas include the news spool, log files, and many other
things in <tt>/var</tt><A NAME="3093"> </A>. You must decide what you consider
important.
<P>
The obvious things to back up are user files (<tt>/home</tt><A NAME="3095"> </A>) and
system configuration files (<tt>/etc</tt><A NAME="3097"> </A>, but possibly other things
scattered all over the filesystem).
