Electronic data storages require electric impulses to process the information you need to backup. For example you can create a backup to your files on a CD. The moment you shut down your computer the data that is on the CD isn’t lost. It stays there and you can use it anytime you want. There are electronic devices that lose their data when they have no electric power. For example, the RAM memory of a computer is a storage device for the computer but the moment the computer is shut down it loses the information. When you open it again you have to take from the beginning.
