A network storage device is one of the best ways to keep your data backed up, but it can be a little pricey to set up and leaving a computer on all the time sucks a lot of power. If you’re looking for a cheap and low power solution, How-To Geek shows off how to use a $35 Raspberry Pi with a external hard drive as a NAS.
The process of using a Raspberry Pi as a NAS is pretty straight-forward and the only additional equipment you need is a USB hard drive (or two for redundancy). First off, you need to do the initial set up process for the Raspberry Pi. Then, you need to run a few commands to get the external hard drive working on the network, set up your PC to send the data over, and you’re all set.
The end result is a NAS that uses about $5 worth of power a year. That’s a huge drop in your utility bill compared to a full computer running all the time, but if you need something with a little more power that’s easy to do yourself as well. Head over to How-To Geek for the full guide to putting this together for yourself.
