I read the doc, but I don't understand the rsync method settings.
"Rsync is run on the remote client via rsh or ssh."
http://backuppc.sourceforge.net/faq/BackupPC.html#_conf_rsyncclientcmd_

The default parameter:
$Conf{RsyncClientCmd} = '$sshPath -q -x -l root $host $rsyncPath $argList+';

I try this:
$Conf{RsyncClientCmd} = '$sshPath -q -x -l username $hostIP $rsyncPath 
$argList+';

but how can I set the password parameter in ssh connection?
