LTM or GTM backup

Hello,

I wish to automate taking backups on ltm and gtm. I want then to be done on daily basis. This is what I have so far -

'!/bin/bash

$DATE=

date "+%m_%d_%y"

'Save config

tmsh save sys config

'Create the ucs archive

tmsh save sys ucs $DATE.ucs

Create a file called config_archive and saved it under /etc/cron.daily permissions are set as well -

[admin@bbc:Active:Standalone] cron.daily ls -l total 10

lrwxrwxrwx 1 root root 36 Aug 14 2013 asm_update_sigfile -> /usr/share/ts/bin/asm_update_sigfile

-rwx------ 1 root root 227 Jun 9 19:15 config_archive

-rwx------ 1 root root 2291 Aug 14 2013 logrotate

-rwx------ 1 root root 312 Aug 14 2013 tmpwatch

lrwxrwxrwx 1 root root 36 Aug 14 2013 update_dpi_sigfile -> /usr/share/ts/bin/update_dpi_sigfile

No luck so far just does not work...Unable to create backups...Am I missing something here??? Can you guys help?

~Thank you
