Dropbox sync question

Hi Everyone,
First time poster here - I’ve checked the other dropbox thread.

Is there any way to get the EX2 Ultra to automatically upload files from storage to dropbox?
I’ve got it to work the other way (i.e. files on dropbox are drawn down onto the EX2) - but what I really need is for files placed on the EX2 to be automatically backed up to the Dropbox cloud.

I read somewhere that Dropbox does not normally work across a network - but should the WD Dropbox app solve this?

My Cloud Share backup to Dropbox is not supported.
