If power consumption was a major problem then you could make a good backup solution on a Raspberrypi.
A Pi even with a USB hard drive would consume less than £10 a year, depending on hard drives used.
You could go even further and run your pi from a solar panel and battery solution making it completely free to run.
After the initial cost of buying the kit to do it.
