Ok, what model are you using? How have you it setup for the NAS?

I've gone with CyberPower - not necessarily saying they are the best choice, but they have worked for me. The most recent purchase was the CP1500AVRLCD. Options here do depend somewhat on your power (I'm in the US). APC is certainly a popular choice, and there are certainly others (Eaton being one I recall off-hand).
On the setup, all you need to do with a single NAS is connect the USB cable on the UPS to the NAS (and of course also connect the NAS to the UPS power). With multiple NAS, you can monitor the primary NAS (directly connected to the USB) over the network - making sure that the switch (or router) is also protected by the UPS.
