How do you keep your home servers online during powercuts? (lemmy.ml)

I live in a part of the world where powercuts are pretty frequent. 1 per day is normal. They last between 1 and 8 hours. A day without powercuts feels like a special occasion.

My machine is powered by a desktop ups which is terrible. It is only supposed to power everything for a few minutes to shutdown safely. But it is cheap and I don't know much about other affordable alternatives.

How do you folks who self host at home deal with powercuts? Any recommendations? 8 hours of uptime from a ups sounds almost impossible or totally unaffordable to me.

Not sure if I'm a fan of the "AliExpress SSD" recommendation. They're badly built and unreliable, you won't know what capacity you get, and they can be incredibly slow.

Regular, known-brand SSDs have dropped so much in price and are very affordable at low capacities. That should be a much safer investment than buying heaps of most likely unusable drives.

    Depends. I used loads of 'known brand' micro SD cards and went trough them one per month. I ordered 2 KingSpec and 'Kunup' sticks, just to test. (june '20) Of each, 1 worked perfectly, 1 was not good enough for continuous use. The active Kingspec has been active for years now, but I use less then 20 GB of the 120 GB SSD. (Really need to clean up logs, OS shouldn't use more then 5G, data is on NAS) The ones that were not reliable enough for continuous use are still in use for transport.

    It worked here and proved a lot cheaper then replacing the SD card every month. As they are Chineese 'unknown brand', ymmv hugely. (and don't buy something that will just fit, as trade GB isn't IT GB and Chineese GBs vary even more) It however is always a gamble to buy something from the other side of the world. (but hey, every 'known brand' is made in China anyway now, so we already are hugely locked into that country)

    With the price of SSDs I'd recommend an internal SSD and SATA or m.2 to USB adapter instead. That way you can choose the enclosure to provide enough cooling, and even open the adapter and add a fan if you really stress the SSD.
