In this paper, we proposed a file backup method. Files in devices of computer system can be destructed under abnormal condition. We divide file or database into ranges. Each range contains records and fields. We backup ranges to different devices. When files process the operation of creation, insertion, update or deletion, we only backup the corresponding ranges. When the original file is destructed, we create it from these backup files. For security, we have method to encrypt files before stored. These operations of backup method make more secure and better performance.
