Backup in Windows 7 is replaced by File History in Windows 8 .
Microsoft redesigned Windows’ backup features since less than 5% of PCs used Windows Backup. The new File History system is designed to be simple to set up and work automatically in the background.
With Windows 7, you can backup any files on your computer like personal files, program files, system files, and anything else. You can also create full system images that can be used to restore your computer to its current state in the future.
In Windows 8, you can no longer create full system images, nor can you backup everything on your hard drive. Instead, you can only backup files in your libraries, files on your desktop, your contacts, and your browser favorites. Windows 8’s File History feature is designed to protect users’ personal files, which are generally irreplaceable. In contrast, there’s less need to back up system files because operating systems and applications can be reinstalled from elsewhere.
If you want to backup a folder elsewhere on your hard disk, you can add it to a library and tell Windows 8 to back up that library. You can exclude certain files in your library from being backed up, but you can’t include files outside your libraries or desktop.
File History is designed to backup your files on a continuous basis, so you can easily revert to a previous version of a file or restore a deleted file. This also minimizes data loss. When setting up a backup with Windows 7’s Windows Backup, the default schedule is to run a backup once per month.
When setting up a backup in Windows 8, the default is a continuous backup that automatically takes a snapshot of the latest versions of your files every hour.
File History incorporates the Previous Versions feature in Windows 7, which allows you to quickly restore previous versions of a file. Restoring files from File History is a similar experience. You can do it right from File Explorer (formerly known as Windows Explorer) – just click the History button on the ribbon.
In Windows 7, you have to open the Windows Backup control panel and use the Restore My Files wizard to restore files from a backup. You can restore a previous version of a file by right-clicking it and using its properties window, but this previous version of a file may come from elsewhere, such as a system restore point – not necessarily from a backup taken with Windows Backup.
