Uninterruptable power supplies (UPS) or PC battery backup can be a valuable addition to your NAS server or desktop PC. Usually, they sit close to your computer and work as an intermediary for the wall outlet power. You can get a good idea of the way a UPS works by considering how seamless the transition is from a laptop’s battery power when the AC adapter is not plugged in.
Some backups come with multiple outlets to use with multiple devices, while some come with an LED screen that displays voltage information, while others are more budget-oriented and barebones. However, all of them provide your PC with emergency backup power. To help determine whether or not a UPS is best for you, we will be looking at some of the most common reasons why you may want to use one.
What does a UPS help to protect against?
A majority of UPS that are worth the price will provide three basic services to you: a voltage regulator, a battery backup, and a surge protector. The surge protector can handle the blast from a light strike that gets too near or something similar, the battery backup gives your computer enough time (5-30 minutes depending on your circumstances and UPS) to shut down normally, and the voltage regular evens out any power fluctuations, such as from a brownout or other event.
Power fluctuations, such as blackouts, sag, noise, and surges, can have a significant impact on your PC’s hardware. It is similar to cooking meat. It will not be edible if it doesn’t get a sufficient amount of heat and burn up if it receives too much heat. The same is true for your motherboard and hard drive. Even if the hardware doesn’t get shocked into retirement, continuous fluctuations will cause it to degrade much faster than when it is used in a normal environment.
The voltage will be automatically corrected by a good UPS to make sure your PC and any other connected devices receive the correct amount of power.
For your OS
Sometimes a power outage can cause your OS to fail completely, particularly if it occurs during an installation or an update. Do a web search using the phrase “Windows won’t boot power outage,” and you find many people look for answers to this problem.
In a majority of situations, this problem will require you to completely reinstall the OS, and it can be a real hassle to reinstall Windows if the proper steps were not taken to back everything up. If you want to completely avoid this problem, a UPS will be very useful, particularly if you automatically set it up to tell our PC to shut down if a power failure occurs.
For your data
Data that is in the process of being written, or being transferred over to an external USB drive whenever the power goes out may be corrupted to the point of being unrecoverable if the power goes out during these processes. That can be a particularly serious problem if you are using a NAS inside your house. Since they are usually a continuous state of rewriting and writing, a power failure can potentially significantly damage a server. When your UPS provides you enough time to properly down your equipment, it can mean the difference between a lost cause and a close call.
