Anybody here connect their DVRs to a UPS? I've had one for quite a bit, but during a power outage the other day, it died in about two minutes. Looking to replace it, but want one that can handle an HR34 and/or HR24 load for at least 10 minutes or so - and maybe longer. (Our weird outages tend to run short for God knows what reason). Not looking to break the bank here, but don't want some cheap POS either. Suggestions?
