While doing on set copying it seems that a UPS system would be a very good idea. If on genny power, someone could pull a plug - if on house power someone could trip a breaker. That would be bad in the middle of a copy.
So: Uninterruptible Power Supplies (UPS). Any recommendations?
First question for me is "How do I determine the size of the supply?" I'm powering a Red Drive, two backup hard drives and my computer. Admittedly the laptop is on it's own battery backup, but I'd feel safer if everything were protected. I could not find data about the power usage for the HDs I was using, but looking around it seems that 12 watts per drive would be a conservative figure. My MacBook Pro uses I think 75 watts. (I'm a little surprised, in this energy-conscious world, that this information isn't on spec sheets). Anyway, assuming I wanted to be able to complete a one hour backup in the event of dire emergency, what size UPS would I need to do that (if it's even possible)?
Second question is "is there ANY disruption if external power is lost?" I'm assuming any disruption could lead to corrupted data; and I'm reading that are "standby" and "continuous" UPS units. I'd assume that the continuous variety is what we would want, but I'd like to know if any data wranglers out there have experience that they could share.
