I know this topic has been covered in the past and I have tried all of the solutions offered.
However, the Synology 220+ was not the NAS in question. I have just bought one and I cannot get the Core to see the 220+ to allow me to set up the back up. I still have my old Netgear Duo V2 and the Core can see that just fine.
I have tried just about everything and fast losing the will to live! Any suggestions will be greatfully received
I also own synology and uniticore. From what i remember I have configured a shared folder named ‘naimcore’ on my DS118, edited permissions and gave read/write access to guest user. This made DS118 available to ‘network drives’ on backup configuration on my core. Later one time connection was lost and core could not see DS118 again. In that case pulling power cord and restarting core made things work again.
