Is a UPS worth it for the router or server rack in a small business?
For the router/firewall and small NAS-or-server: almost always. For laptops: never, they already have a battery.
Try this first
- 1For a router or modem alone, 350-600 VA is more than enough. For a NAS or small server too: 650-1500 VA. Goal: ride out dips and gracefully shut down on long outages, not hours of work.
- 2On a NAS: connect the UPS via USB so the NAS shuts down before the battery dies.
- 3Replace UPS battery every 3-4 years. A UPS with a dead battery is just an expensive power strip.
- 4Test: once a quarter pull power from the UPS and check what stays up. No test = no UPS.
