Your actual line seems to be:

rsync -e ssh -varuzP /backup/BACKUP-NEDS-LX-1-`date +%Y-%m-%d`.tar.gz administrator-Q0ErXNX1RuYmaKRe3I/nfg at public.gmane.org:/backup/

Here's what you need to do:

ssh-keygen -t rsa -b 2048 -C "administrator rsync key" -f admin.key

  Put in no passphrase.

  Edit admin.key.pub to add this at the beginning of the first line:

from=192.168.247.10,no-X11-forwarding,no-port-forwarding,no-agent-forwarding,no-pty

  Change 192.168.247.10 to the IP address of the machine you are working on.
  This is for security's sake. You may also want to append
,command="rsync"
  or a variant thereon.

ssh-copy-id -i admin.key.pub 192.168.247.34

  That appends the key to administrator's ~/.ssh/authorized_keys   

And finally, change your line to:

rsync -e "ssh -i admin.key" -varuzP /backup/BACKUP-NEDS-LX-1-`date +%Y-%m-%d`.tar.gz administrator-Q0ErXNX1RuYmaKRe3I/nfg at public.gmane.org:/backup/
