Hi Mikkel --

tried:
sudo -E /usr/bin/rsync --stats -ae "ssh" --rsync-path="sudo
/usr/bin/rsync" /my  rsync at genepinfs:/backup/my

after added to /etc/sudoers:
rsync   ALL=(ALL)       NOPASSWD: SETENV: /usr/bin/rsync

still get a prompt for a password for the remote machine. If I remove
the 'sudo -E' in the
beginning it doesn't ask for a password on the remote machine, but
authorization on the local machine
doesn't work (as root), if the rsync user has permissions all is well
on both ends.

 Is this the correct way to set setenv?

Thanks for the help,
