What convenient solutions exist for graceful shutdown of a NAS, without data loss or other drama, in case of power outage? It seems a more pressing concern than flipped bits or network failures.
A filesystem designed to survive sudden power loss? Which is most modern ones right?
My Helios64 has a built in backup battery. I'm not sure they are available anymore (and I wouldn't recommend anyway for other reasons) but I imagine other NASs have similar setups.
The common solution is having an UPS and a NAS that supports graceful shutdown when the UPS detects powerloss
