Thank you for your reply.

No I dont get any error message for the backup.

Is it possible you can share your aixback.sh, so that I can see what I have done wrong.

I also try to run a command as :

59 23 * * * /usr/lpp/CPfw1-41/log/fwtestlog.sh

But error : Execute permission denied.

One more thing, how do you configure the sendmail so that it can mail to my mailhost.
