Software to backup data and files on a Windows computer

I have data and files on my system, running Windows, and want to make sure that I don’t lose all the data or information when it gets toasted, either by a power surge or corrupted medium.

I’ve heard that I should look into some kind of archive tool.

What should I be looking into here in a backup program?

Solution:

I use SyncBack by 2BrightSparks. It has a wide range of functions, including backing up to a network drive, and synchronising two folders. The free version has been sufficient for my needs.
