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.
The batteries should not degrade that fast. Get a name brand like Eaton or APC or something like that similar to a Power supply, cheap devices can do harm to your expensive devices. Have a couple of setups where the batteries (lead acid) are 5+ years old and they work ok.
For real!
I use several refurbished APC UPS’, and also use third-party batteries (from the company that refurbishes the UPS’) and it’s been trouble-free for like 10 years. I replace batteries, it seems, every 4-5 years and only when the self-test says to replace it.
Never had a problem with data loss due to the UPS failure.
APC is garbage. Get Eaton. Lead acid batteries should last 3-5 years.
APC makes some good stuff. It’s just all their consumer stuff is garbage.
If you can get a rack mount unit from a data center those are real nice. Just don’t try to buy them brand new.
