How to exclude a dir. with tar

[Guillaume <guillaume.chardin@xxxxxxxxx>]

Hi list...

I try to make a script to save my computer. I would like tu use tar to create a  file and then compress it.
I have a directory to save located in a home dir, but inside it a temp dir I dont want to save. I try the --exclude option of tar to discard this one, but it don't seem to work.
Someone can help me?

Can i use in the same way the ' -X option to exlude more than 1 dir?

tar --acls --append --exclude /home/web/current/temp  -vf /data/save/save.tar /home/web/current/ >> /data/save/sauve.log

Thanks for your help.
