NAS in a country with 3-4 hour power cuts

[ed]

Living in a place with frequent 3-4 hour power cuts can be a real challenge when it comes to keeping your NAS up and running. A UPS is indeed a good solution, but you'll need a robust one to meet your needs. To power a 62W NAS for up to 4 hours, you'd require a UPS with a considerable capacity. I recommend looking at the APC Smart-UPS series. Specifically, the APC Smart-UPS 1500VA should provide sufficient power to keep your NAS running during these power outages. It's always a good idea to oversize the UPS a bit to ensure you have ample backup power. Just make sure to calculate the exact power requirements for all your devices, including the NAS, and choose a UPS that can handle the load.
