All,
 
Thank you for your help.
 
Finally I got it working by adding bpbackup command in the end.
 
Now the problem I am facing is Üser Backup is running 4 to 5 times instead of just once. What could be the reason for that ??
 
Here's  the script I am using .
 
----------------------------------------------------------------------------------------------------------------------------------------
 
#!/bin/bash

#The below command will delete the older backup
rm -r /mysql_backup/201*
 
TIMESTAMP=$(date +"%Y%m%d")
BACKUP_DIR="/mysql_backup/$TIMESTAMP"
MYSQL_USER="mysqlbak"
MYSQL_PASSWORD="Cricket1"
MYSQL=/usr/bin/mysql
# MYSQLDUMP=/usr/bin/mysqldump
MYSQLDUMP=/usr/mysql/5.1/bin/mysqldump
mkdir -p $BACKUP_DIR
databases=`$MYSQL -u$MYSQL_USER -p$MYSQL_PASSWORD -e "SHOW DATABASES;" | egrep -iv "(Database|information_schema)"`
for db in $databases; do
# echo $db
mkdir -p $BACKUP_DIR/$db
BACKUP_DIRR="/mysql_backup/$TIMESTAMP/$db"
$MYSQLDUMP --force --opt --user=$MYSQL_USER -p$MYSQL_PASSWORD --databases $db | gzip > "$BACKUP_DIRR/$db.sql.gz"

#The below command will start NetBackup Tape backups
/usr/openv/netbackup/bin/./bpbackup -w -p SOPMYSQL02 -s sopmysql02-backup /mysql_backup/
 
done
