Matey if that sorts It I owe you a beer

I will try tonight
I have a windows O/S on my PC, I have mapped a network drive on the PC for my 320L using the map network location app in windows 8.2, the physical address mapped looks like this when I click the link (I get an error because I am at work just now) \\192.168.?.??\Volume_1 for the Root
If I browse a local folder on my PC now for example '' how exactly would I express this in the backup location sting of data on the 320L for LAN backup 'of the Odd Pictures Folder' ?
The PC has a name on my network lets call its name ERIC, so would the address be"
\\Eric\C:\Users\my_userid\Pictures\Pictures Year 2001\Odd Pictures"
All I want to do is backup on a schedule the contents of a location, the NAS can do this without me having to faff around once its set-up to do it, I know I could just copy / paste but that 100% rely's on life not getting in the way.
Ideally and I cannot see how this could not be done I could backup the pictures on my telephone (Android) in exactly the same way, the phone has an IP a network connection folders etc..
Am I trying to Paint the moon here, the device was £40 so I am making some allowances for the poor web app etc.

but reading the tech talk on this device its not so bad for the money, trying to figure out what should be soooooo easy is the frustrating bit
