Coping the data AND programs on a removable media, and store in another physical building, in lock and key, is called backup.

  • Restore program is required to get the data back.

Why Backup?
  • Remember, 9/11 attack?
  • Now a days most of the information is stored in computer hard disk, and not in paper format. Less=paper office, is a good idea, but not taking backup is not safe.
  • The computer disk may malfunction or virus attack may corrupt the data.
  • It is necessary to take backup of the data and programs because organization can't afford to loose the same.
