Module Name + FrontView Question

Rsync from a computer seems to need a ReadyNAS module name (rsync daemon) as the first part of the PATH, but I cannot find in any NetGear documentation what the name of that software is on the NAS (OS6 I'm now running firmware 6.1.9) to include in the PATH in an rsync command. How do I determine the name to provide to rsync? I'm referring to the text at the end in the rsync Help info:

Usage: rsync [OPTION]... SRC [SRC]... DEST
  or   rsync [OPTION]... SRC [SRC]... [USER@]HOST:DEST
  or   rsync [OPTION]... SRC [SRC]... [USER@]HOST::DEST
  or   rsync [OPTION]... SRC [SRC]... rsync://[USER@]HOST[:PORT]/DEST
  or   rsync [OPTION]... [USER@]HOST:SRC [DEST]
  or   rsync [OPTION]... [USER@]HOST::SRC [DEST]
  or   rsync [OPTION]... rsync://[USER@]HOST[:PORT]/SRC [DEST]
The ':' usages connect via remote shell, while '::' & 'rsync://' usages connect
to an rsync daemon, and require SRC or DEST to start with a module name.

I'm getting an Error from a rsync GUI tool ("luckyBackup") asking for a module name:

ERROR: The remote path must start with a module name not a / rsync error: error starting client-server protocol (code 5) at main.c(1534) [sender=3.0.9] 

The rsync command being used is:

rsync -h --progress --stats -r -tgo -p -l -D --update --delete-after --password-file=/home/jim/bin/rsyncpw /home/jim/TestFiles rsyncjim@192.168.0.215::/tmp/nas/

and it seems to want a module name after the double colons, but that doesn't seem correct to me - the "/tmp/nas" is the local mount point path on the local computer.

Only somewhat related - Is Neatgear FrontView software appropriate for my RN102? I have formed the impression FrontView is for older products and not for newer ARM processor models - Right? For my RN102 there is no software to access the NAS OS other than logging into the admin account for doing configuration actions.

Thanks
