Power outage worries (feddit.it)

Hi fellow hosters!

I do selfhost lots of stuff, starting from the classical '*Arrs all the way to SilberBullet and photos services.

I even have two ISPs at home to manage failover in case one goes down, in fact I do rely on my home services a lot specially when I am not at home.

The main server is a powerful but older laptop to which i have recently replaced the battery because of its age, but my storage is composed of two raid arrays, which are of course external jbods, and with external power supplies.

A few years ago I purchased a cheap UPS, basically this one: EPYC® TETRYS - UPS https://amzn.eu/d/iTYYNsc

Which works just fine and can sustain the two raids for long enough until any small power outage is gone.

The downside is that the battery itself degrades quickly and every one or two years top it needs to be replaced, which is not only a cost but also an inconvenience because i usually find out always the worst possible time (power outage), of course!

How do you tackle the issue in your setups?

I need to mention that I live in the countryside. Power outages are like once or twice per year, so not big deal, just annoying.

If you drain the UPS past 50% it really kills the life of the batteries.

In the Enterprise you probably have generator backup. So the UPS only need to keep things running for 30 second to a minute. So that never happens.
