The Clickfree Backup Software has been developed to backup only the data that you have created or copied to your computer - photos, videos, music, emails, documents, tax information and so on.
The first time you back up your computer, Clickfree backs up all of the content it finds, which might take several hours, depending on how much content you need to back up. Each time you use Clickfree after that, it only backs up the changed content, so it will be much quicker. Any files that were deleted from your computer since the last backup are not deleted from the USB drive.
