Title: EFS RECOVERY AND BACKUP METHOD, SYSTEM AND TERMINAL
Abstract:
An EFS recovery and backup method, system and terminal. The EFS recovery method comprises: detecting whether there is a damaged EFS file in an EFS storage area (S21); when it is detected that there is a damaged EFS file in the EFS storage area, writing EFS content in an EFS backup area into the EFS storage area (S22), wherein the EFS content in the EFS backup area is backed up according to a pre-set backup policy. In this way, when a terminal crashes due to abnormal power failure and an EFS file is damaged, EFS recovery can be performed by means of the backed-up EFS content.
