Isn't there any UPS which lasts for hours? null

UPS devices in this class can last hours under light loads but generally they are not designed for holding up loads for long periods of time. This problem is the limited size of the batteries that can fit into these units. UPSes with larger batteries or the ability to add additional batteries tend to get pricey very quickly. A possible solution could be to split up your loads across multiple UPSes.

How long the UPS lasts depends on the size of the UPS and on how much power your devices are using. The less power, the longer it will last. You can buy larger UPS units with bigger batteries to get it to last longer, and some higher end UPS units can also add expansion batteries to extend run time. UPS are not really intended to run for long periods of time however. The best solution for longer power outages is to combine a UPS and a backup generator. The idea being that when the power goes out, the generator is automatically or manually powered on at some point, and the UPS only needs to support your computer/devices for long enough to get the generator online. If you have long power outages often, that would be the best solution, install a backup generator on your home (if possible) and just use the UPS to cover the short gap in power. If a generator is not possible, you might have to do some creative engineering such as multiple UPSs, each dedicated to a single device, to get more run time for all of the devices, or prioritize which devices absolutely need to have backup power. For example, if you have a laptop with dock/external monitor, you don't really need the external monitor to have power, you can use the laptop by itself, and the laptop is likely to have hours of backup power built in anyway.

You have to first look at the load/demand. So, for example with a 1500VA, you have a NAS, 2 Cable Modems (one back up for work) and a wireless Router. Total WATTS = 120+- with a run time of 83 min. If you have a storm and lose power, turn off the NAS or nonessential AND unplug its power brick. This will improve the run time. Turning something off is not enough. Those bricks draw power too, this is where the run time suffers. You still have internet and jump up to 193 min (3hour+). If you have a larger unit, PRO type, you can reach 243+(4 hours). If internet up time is important and critical, split the load across two units. don't plug everything into one unit. Remember, over time (1.5 to 2 yrs.) your batteries degrade. Maintenance is important.
