rsync - Aug 2004 - rsync using sudo via remote shell

Hi!

I'd like to use rsync to make incremental backups of my webserver. The 
ssh daemon on the server does not accept root logins, but I can login 
(key, no password) as a regular user and then execute rsync via sudo.
Without root login limitations I'd be able to use something like

rsync -avz -e "ssh -i /home/backup/.ssh/id_dsa" backup@server:/ 
/backup/server/

Unfortunately I can't figure out how to tell rsync to execute its remote 
instance via sudo. Any help appreciated.

Thanks,

Achim.

You can do this via the --rsync-path option:

rsync -avz -e "ssh -i /home/backup/.ssh/id_dsa" --rsync-path='sudo
rsync' backup@server:/ /backup/server/

You'll also want to make sure that sudo doesn't prompt for a password,
so you could start with a simpler command right before the rsync:

ssh -i /home/backup/.ssh/id_dsa -l backup server sudo date
