We designed File History with two objectives in mind; 1) offer best possible protection of user personal files and 2) offer ease, simplicity and peace of mind," wrote Bohdan Raciborski, a Microsoft program manager, in a blog post.
The operation of File History is transparent and doesn't affect the user experience, reliability or performance of Windows in any way.
To use File History, Windows 8 users need to turn it on and select where the backed-up files will be stored.
If users are fine with using the default settings of File History, they don't need to do anything else.
Unlike other Windows and non-Windows backup and restore utilities, File History has been designed to only protect personal files, not the entire contents of a PC.
This means that File History will concern itself only with files stored in the Libraries, Desktop, Favorites and Contacts folders, and will not back up the OS or applications.
