Sudo + ssh and rsnapshot

Hello list,

I'm a newbie in rsnapshot but seems to be amazing :)

I've got various linux server configured to use  sudo
the root access is disabled (like in Ubuntu)

How can I setup rsnapshots to get data from these servers

I think that I should do  :
- do ssh public keys exchange between servers

- configure sudo to allow  rsync call without password

LAN = NOPASSWD: /usr/bin/rsync ...


I believe that I need to call a line like this ...

//rsync -avz -e "ssh -i /home/backup/.ssh/id_dsa" --rsync-path='sudo rsync' 
backup at server <http://lists.samba.org/mailman/listinfo/rsync>:/ 
/backup/server///


But with rsnapshots how can I do that ?
Thanks for your help

Regards

Sebastien
