Having one or more backups is essential. 

  Sooner or later, you most likely will have something go
  wrong and lose your personal files, documents or photos.
  Examples include accidentally deleting the wrong files,
  hardware failure, losing your laptop or infecting your
  computer. At times like these, backups are often the only
  way you can rebuild your digital life.

  Dropbox is a file hosting service operated by Dropbox, Inc.,
  headquartered in San Francisco, California, that offers
  cloud storage, file synchronization, and client software.
  Dropbox allows users to create a special folder on each of
  their computers, which Dropbox then synchronizes so that it
  appears to be the same folder (with the same contents)
  regardless of which computer is used to view it. Files
  placed in this folder also are accessible through a website
  and mobile phone applications.
