rsync script error

[sgoldman-DPNOqEs/LNQ at public.gmane.org (Stephen Goldman)]

Good afternoon Blu,
    I 've been doing a hit and miss with a rsync script I wrote that is not working.

    Appreciate a review from more experience eyes and suggested reference -

    RHEL system-Red Hat Enterprise Linux Server release 5.4 (Tikanga)


    I have an NFS mount from a NET APP filer that is running ".snapshots" of the directory mounted on
/mnt/external -- wish to sync to /data/biomicro/external AND skip .snapshots - on mnt/external- 
send email message - script to be run from cron.daily 



   Combining the --delete and exclude statements is confusing. 


#!/bin/bash
/usr/bin/rsync -avz --delete / --exclude ".snapshot"  /mnt/external/. /data/biomicro/external  >> /var/log/rsync/backup.log mail -s "back cron job external ran" sgoldman-3s7WtUTddSA at public.gmane.org
~
When I test from /root   - I error out. 
]
rsync: -s: unknown option
rsync error: syntax or usage error (code 1) at main.c(1231) [client=2.6.8]
[root@ ~]# 



Thanks for your input,



Stephen

Using Rsync Itself
  Now on to actually using, or initiating an rsync transfer with rsync itself. It's the same binary as the daemon, just without the "--daemon" flag. It's simplicity is a virtue. I'll start with a commandline that I use in a script to synchronize a Web tree below. 

rsync --verbose  --progress --stats --compress --rsh=/usr/local/bin/ssh \
      --recursive --times --perms --links --delete \
      --exclude "*bak" --exclude "*~" \
      /www/* webserver:simple_path_name
