I don't want to bore you with my whole IT set up - that's rather a small data center.
I have split all my equipment into two sections:
1. weather related (APS BACKUPS 700)
2. non-weather related (APS BACKUPS Pro 1200)
Each one has got their UPS. As I understand the OP and OPer and his reactions on several posts, 2. is of no interest, and why would it be.
Let's come to the weather equipment - all my consoles (see my signature), the WiFi router used for the consoles, a WAN/LAN VPN firewall router (internet WAN interface), an ADSL2+ modem (they are separate in my case, with most people it's all in one box, but there are reasons [for me] to keep them separate), my Meteobridge Pro data loggers, my Raspberry Pi-s and a USB hub are connected to it.
In addition comes a Windows laptop on which the database software of my WH4000SE/WS2320E console runs and the temperature/humidity sensor data of my TFA Klimalogg Pro system (mainly greenhouse and sanity check of my WH31-EP) are recorded. Also the surveillance software of the UPS and Brian Hamilton's Weather Display; plus the data recording of my Blake-Larsen sunrecorder.
In short - (almost) all weather related components on one UPS.
My NAS systems which house backups of the weather data, record data from my weather cameras and also host a local version of my Weather34 website (parallel backup) and my PoE switch for my weather cameras are connected to my non-weather related UPS which protects the remainder of my IT infrastructure. That's an APC BACKUPS Pro 1200.
In case of a power outage in my absence, it (the APC 700) can keep the equipment running for 36 -42 minutes. In my presence, I could still reduce the load on the UPS such that it would result in 60 minutes by selectively shutting gracefully down my backup systems (mainly backup consoles and a backup RPi). Even up to 90-120 min if I shut down gracefully my Windows laptop (The connected consoles have an internal memory - only WD and SR data would get lost for the downtime). The APC 700 I use does regularly (once a month) a self-test, i.e. simulates a power blackout to check the functionality and give the batteries a discharge/recharge cycle.
An architecture scheme of it (without the TFA Klimalogg components) can be viewed on my Weathercloud presence -
