backup help

[|Leviathan|]

hi there,

i have a linux system running as a mail server, not that big a deal running fedora core 4

now, each and every night i backup the mail directory folders using automated script

problem is that i need to leave out a couple of folders out of the backup

at the moment this is what code i have in my scripts

tar -zcp /home/vpopmail > /backup/tape1/vpopmail.tar.gz

now i could implement more lines of code to back what i need etc, but that would mean quite a lot of hassle to maintain etc, is there a way how i can instruct through code to leave #so and so out of the the zipping process?

thanks for your help
