Amazon Cloud Sync not working bidirectionally
I am running a NAS RN204 with firmware version 6.10.1. I have it set to back up a specific folder (photos) to my Amazon Cloud drive. This is set to back every 5 minutes and does so into the directory ReadyNAS_nas204.
Files and directories inside the NAS under photo get properly backed up to the Amazon cloud drive. Even though I have the NAS set to sync bidirectionally, nothing I add or change on the Amazon cloud gets pushed back to the NAS.
Am I doing something wrong or expecting the cloud sync to work differently than designed?
Thanks in advance for any help.
