Thanks Jack and Michael for the pointers! Sorry to take so long to get back. I've used the --exclude option as Michael suggested for now. Also thanks for pointing out the -z option for tar; believe it or not I thought I was actually using that already, I guess my biggest problem is not paying attention :)
I'm also going to take a look at cdbkup. I'm not so much trying to reinvent the wheel really, as I am trying to get more familiar with scripting. As I already mentioned, I really glazed over two really obvious options that were available to me (doh!) I also like the simplicity of being able to use stuff that's already on my system. Thanks again! Mike > why reinvent the wheel? Go to freshmeat.net and type cd backup into the > search. cdbkup is the one I picked, it seems to work.
