I was about to create a folder to keep an archive my important files in. This question got stuck in my mind while renaming it.

How do I have to rename that folder?

  • Back up
  • Backup
  • Back-up

Are all phrases correct?

This question is too basic; it can be definitively and permanently answered by a single link to a standard internet reference source designed specifically to find that type of information.If this question can be reworded to fit the rules in the help center, please edit the question.

This and this. Also, this. Use it as a general rule. – RegDwigнt Aug 15 '12 at 12:45

With the computer age, the noun "backup" is well-accepted and understood. So "Backup".
