Windows 8 comes with completely new backup application known as File History. This feature backs up files and data in the background automatically and allows users to restore these files and data from an easy time based interface. For creating backups of files, most people like the software, Crash plan as it enables people to back up files to the internet and is more configurable.
This is pretty essential if people want to secure their files and data. But most users like more to utilize built in tools/software for quick backups. In that situation, File History is an excellent alternative.
