CentOS 5 :: No Items From /etc/cron.daily Run On 5.3

I'm having a very strange issue with cron on centos 5.3 64-bit. I have 3 cron scripts in /etc/cron.daily which run backups. They are as follows:

script1:

#!/bin/bash
/usr/local/bin/backup-script1

script2:

#!/bin/bash
/usr/local/bin/backup-script2

script3:

#!/bin/bash
/usr/local/bin/backup-script3

The contents of the 3 /usr/local/bin scripts are ...

/usr/local/bin/backup-script1:
#!/bin/bash
synbak -s srv1 -m rsync
rsync -av --delete /data/backup/srv1/* root@::share/srv1/

To explain this, the 1st active line does a synbak backup and the 2nd active line rsyncs the backup data to a remote server.

/usr/local/bin/backup-script2:
#!/bin/bash
synbak -s srv2 -m rsync
rsync -av --delete /data/backup/srv2/* root@::share/srv2/
