Sorry about the delay getting back to you on this. Disappeared into the
ever-increasing backlog of mail in my inbox.

To find the correct rsync command; get a working rsync connection going;
then copy what you see as the arguments to rsync (options following the
file) in 'ps ax'. It should end up looking something like this.
no-port-forwarding,no-X11-forwarding,no-agent-forwarding,command="sudo
/usr/bin/rsync --server --sender -logDtpr --exclude='/proc/*'
--exclude='/mnt/*' --exclude='/sys/*' --exclude='/tmp/*'

--exclude='/var/log/*' --delete --numeric-ids --block-size=2048 . /" ssh-dss

Why are you using rsyncd instead of rsync invoked via ssh?
Normally when you run 'rsync -avz user@remotehost:/path/ /localpath' it
actually invokes ssh as the transfer mechanism. (In the bad old days it
defaulted to rsh and one had to explicitly specify '-e ssh' to make it use
ssh). Rsync makes an ssh connection to the remote side and starts rsync on
that side, sending the output back down the ssh tunnel to the local instance
of rsync. No rsyncd needed.

That looks like an invocation using rsyncd; which I would avoid. The time to
use rsyncd is when backing up Windows, because cygwin ssh+rsync is buggy and
doesn't work.
Keep in mind that BackupPC has both:
$Conf{XferMethod} = 'rsyncd';
$Conf{XferMethod} = 'rsync';
You should use 'rsync' for your XferMethod unless there's a really good
reason.
here's the RsyncClientCmd that I use with the above-listed ssh key.
$Conf{RsyncClientCmd} = '$sshPath -q -x -l rsyncbakup $host $rsyncPath
$argList+';
