Trying to create a backup to a rsync server on NAS4Free. When attempting to run the backup an error message appears,

"ERROR: The remote path must start with a module name not a /
rsync error: error starting client-server protocol (code 5)"

Placing the module name in front of "/mnt/testfolder" has not worked.

Not quite sure where to go from here. Any insights are appreciated.
