Also do you know what power measurements this device uses on regular basis so i could use the APC battery backup selector tools below to determine the APC device to purchase based on how long it will keep the NVX running?

The hardware manual is here: http://www.downloads.netgear.com/files/GDC/RNDU2000/ReadyNAS_Ultra_UltraPlus_NVX_Pro_HW_en_8July11.pdf

On page 39 it says: NVX Pioneer and NVX (Business Edition): 76W (with 4 x 1 TB disks).

FWIW, I use a CyberPower UPS that is rated at 1350VA.

Does this mean I am able to use ANY model apc battery backup or does it need to be a smart ups model?

You need a model that includes a USB connector for monitoring. The Network UPS Tools folks maintain a compatibility list here: https://networkupstools.org/stable-hcl.html

For the NVX or other systems that still run older firmware, the list at the NUT site might include ones not supported by the older version of NUT that's in the firmware. There are notes about the min revision of NUT for some UPS, but I don't know which version is in the 4.2.x firmware.

    So I am currently running RAIDiator 4.2.31.
    
    So what i will need to do to get this to work is using a PC that is directly connected to any USB port on the NVX and then install this NUT software on the PC and then configure the NVX to shutdown on threshold in the NVX web gui?
    
    Also thank you both for your helpful answers!
