According to an article from Steven Sinofsky on the Building Windows 8 Blog:
Enable File History in Windows 8
To use the File History feature, you’ll need a connected external or network drive. As with anything in Windows, there’s several different ways to get to it. When you’re on the Metro Start screen, hit Windows Key + W to bring up Settings Search. Type: File History then select the icon under the results. Or, when you plug an external drive into your system, click the message that AutoPlay pops up.
Then select Configure this Drive for Backup File History.
File History is off by default, but you’ll see your backup drive listed. Click Turn On.
It will run a backup of all of your important data right away and will do that every hour by default. Or you can go back in and click Run Now.
Under Advanced Settings you can control how often it scans your system for changes. You can select from every 10 minutes to everyday.
To add a network drive, click Select Drive. Then click Add Network Location and browse to the directory you want to back up to.
There’s quite a bit more you can do with this and I will be covering that in depth as our Windows 8 coverage continues. This is one of the first things you should turn on when you get a new Windows 8 computer this fall. Comment Name * Email *
