    I use this to provide backup for a small Home server that I run. Can I have it configured on the server so is that if the battery runs under a certain amount that it will gracefully shut down. This has been probably one of my best purchases in terms of peace of mind, even though I've never had to actually rely on it (as far as I know). At the time of purchase this was the cheapest ups that had a USB port capable of communicating with a PC/server.
