Abstract: A backing up and recovering method of a file system is applied to a communication device. In the backing up and recovering method, a detecting step is performed to drive a first processing unit to detect whether the file system is damaged, and then generate a detection result. A transmitting step is performed to drive the first processing unit to transmit the detection result to a second processing unit. In response to the detection result being the file system is damaged, the second processing unit executes a system recovering step which recovers the file system according to a backup data that corresponds to the file system and is stored in a storage unit, and in response to the file system being not damaged, the second processing unit executes a backup confirming step which confirms whether the storage unit has the backup data.
