Use Drobo to backup NAS?
I've recently upgraded to a QNAP TVS-473 NAS which I'm using primarily for Plex but I also store other my other data on it. I now have a spare Drobo S which I was hoping to repurpose as my primary backup but I can't connect direct to the NAS because it needs the Drobo dashboard to work properly.
Would it be possible to backup up my NAS using Timemachine on my Mini? The Drobo is connected by USB3 to my Mini, while both my NAS and Mini are connected to the same router by Ethernet?
Thanks in advance
