At least one level to deep, actually I wouldn't even step into "mail", just cd 
to /suse102/home/bruce/.kde/share/apps/KMail

As Werner already wrote, the second path is not what you want to have.
Basically you can use any path for the archive file, e.g. 
/home/bu4lu3si1/suseKMail.tar.bz2, but the path used to specifiy the directory 
or files to archive will also end up in the archive file and be restored when 
extracting.

So if you do

cd  /suse102/home/bruce/.kde/share/apps/KMail
tar -cvjf  /home/bu4lu3si1/suseKMail.tar.bz2 mail/

You will get an archive file in  /home/bu4lu3si1/ which contains one directory 
called "mail/".
Extracting this will create a directory "mail/" in whatever directory you run 
"tar -xvjf" in.

This means that Werner's suggestion will not include any top level directory, 
so this is probably even easier.

cd /suse102/home/bruce/.kde/share/apps/KMail/mail

tar -cvjf  /home/bu4lu3si1/suseKMail.tar.bz2 .

You will get an archive file in /home/bu4lu3si1/  which only contains files 
and sub directories of "mail/", not he "mail/" directory itself [1].

Correct, or /home/bu4lu3si1/.kde/share/apps/KMail if "mail/" is part of the 
archive.

That was the intend of the orginal suggestion, i.e. running the tar commands 
from the same conceptual level, i.e. the home directory.
Of course the mail directory itself or the KMail data directory can be used as 
well, like the suggestion above demonstrate.

Cheers,

[1] I personally prefer to have at least one directory level in an archive so 
I can extract it whereever I want without filling the current directory with 
lots of files. Both variants are funcationally equivalent, mainly a matter of 
taste.
