Backup Problem

[Ankur Ganguli]

Hi,

I am running this script bellow in a RedHat Linux System - Kernel 2.4.21-32.0.1.ELsmp for three different databases;

folder=`date +%d-%m-%Y`
cd /backup
mkdir dbbackup_$folder
cd dbbackup_$folder

mysqldump --opt dbname > /backup/dbbackup_$folder/dbname.sql
mysqldump --opt dbname > /backup/dbbackup_$folder/dbname.sql
mysqldump --opt dbname > /backup/dbbackup_$folder/dbname.sql

But from last there is no backup is taken; in the destination folder there is 3 *.sql file are there but the it contain nothing and the file size is 0 bytes. Before that the backup is fine. So please give me some suggestion or solution for this problem.

Thanks & regards
Ankur
