Software :: Mysql Full Backup Script Not Archiving The Dump File?

I have a problem with a script i wrote, the script runs fine if manually executed however it doesn't run *fully* when executed via cron

here's the script :

Code:

#!/bin/bash
FILENAME=mysql_full_dump_`date '+%m.%d.%y'`.sql
`which mysqldump` --all-databases -uroot -p************ -h127.0.0.1 > /root/$FILENAME
RETVAL=$?

[code]....

the script resides in /root/bin and the cron entry is as follows:

Code:

0 0 * * * root "/root/bin/mysql_daily.sh"

the result is the .sql file, but it doesn't archive it.
