If you're using ssh you aren't talking to the rsync server (unless
you're only using as a tunnel). The rsync server only listens for

You'll need to be root on the machine receiving the files in order to
create them as different users, but you don't need to be root on the
sending system -- you just need enough permissions to be able to read
all the files (e.g. group access is fine, if that is possible). The
ssh command can log into the remote machine using any user, so you
could run a pull command (as root) like this:
rsync -av user at remote.com:/path /backup
This would log into remote.com as "user" -- as long as "user" was able
to read all the files you wanted to backup, you'd be fine.
If you end up needing root access to read everything that you want to
backup, you may wish to enable a read-only rsync daemon that is running
as root (possibly chrooted). You can set it up to be password protected
and to only allow connections from localhost, which would let you use
ssh to tunnel a daemon connection. See the ssh docs for the tunnel
syntax and the rsync docs for the "::" syntax (avoid -e/--rsh too).
