How to do backup using SuperDuper

If you only need a backup of an item, you can move its content to an external storage device such as a USB stick or copy it to a web hosting service such as Dropbox, iCloud, or Google Docs.
However, if you have a lot of content that you want to save, it may be easier to duplicate the entire contents of the disk to an external drive.
