All you need to do is to append the backup_exit_notify script with the below lines

if [ "$5" -gt 1 ]
then
        cat $OUTF | mailx -s "$2 - Exit Status = $5" abdcd@abcd.com

this is for unix environment.

Basically $5 is the exit status code. Hence by giving the above condition and error apart from "0" and "1" will be email to you.

You can use this syntax for other script files are well.
