Windows Backup did not gain an amazing reputation – people that use it, use it mostly because it’s convenient and free, rather than because they feel they can count on it.

However, with the migration towards Windows 8, Microsoft hopes to get its users hooked on their backup system, with a different type of backup – a continuous one.
