I've been using File History for about a year now and I can say that I barely feel its effect when its backing up my files.
Yes, it's true, to be honest, I though it stopped working, but when I checked when was the last backup made, I am surprised that it was only yesterday that the last backup has taken place successfully.
In File History You can choose what folders are going to be backed up and how often the backup will take place (automatically).
In my case I choose an interval of 6 hours for my office computer. I only use my office computer for 8 hours every day and the interval of 6 hours is pretty good for me.
I am using a second hard disk drive as my backup storage.
I do recommend to use a second hard disk like I do.
I saw some users complain about the speed of the backup process when they are using a USB flash drive or external USB drive (maybe it depends on what type or how fast the USB drive that you are going to use).
The size of the hard drive that I am using is only 1TB that is connected with a SATA cable.
The current size of my File History backup is 129 GB
How to use File History
You need a separate storage to use File History. It can be another hard disk drive if you are using a desktop computer and a USB flash drive or USB external hard drive for a laptop computer.
Make sure to use a USB 3.0 of higher type flash drive or USB external drive so that you get to experience the fastest speed ever possible in copying files.
To enable File History just search File History on settings or with Cortana and follow the instructions provided.
Keep in mind that you might experience sluggishness on your computer while it is performing backup for the first time.
The backup process is taking place in the background so there is not windows being displayed during the backup.
