RSync - am i missing something obvious? (RN312/RN102 with 6.10.4)

I am having the exact same symptom on a deployment with a 3312 backing up to a 314. When running on 6.10.3 the Rsync via SSH functions correctly to backup the entire volume (/data), but if I upgrade to 6.10.4 the back-up says it runs successfully in a few seconds (should take it a few hours nightly) and dones't update any of the files, but will only update folder structure changes. For now I reverted back to 6.10.3 for now and rsync works again. Hoping for a fix on this. Different problem, but still not fixed, the backup setup still messes up the destination file address with an extra "\" when using the gui and I have to edit it out of the backup scripts via ssh before the rsync via SSH even works to begin with.
