Hey,
I'm looking for some help on my little backup script for my server.  I'm
not a real savvy scripter so please bare with me :)
I googled around awhile back and put together a bu script that has served
my purpose well until now.  It's just a few lines as you will see and I
use it with cron to make a cdrw every morning at 3am.
Now the info on my server is starting to outgrow just on cdrw (jpgs and
such) so I would like to know how I can modify my script to be able to
exclude either certain files or directories.  I imagine that sed would be
involved, but I don't completely understand that tool so I'm hoping that
someone might be able to give me some pointers and maybe even explain how
the code will work in that setting.  Well, here's what I've got now:
Michael,

attached you'll find the one i've been using and it works flawlessly. I 
can't remember his name, but it was a gentleman here on the expert list 
that sent me a copy of his and I used his as a guide to cook this one up.

enjoy...
