Self-rescue method and device for damaged file system

摘要

The present application discloses a self-rescue method and device for a damaged file system. The method includes: a fault warning message is sent to a background server when it is found during boot of a device that a file system is damaged; the device receives an acknowledgement message from the background server, wherein the acknowledgement message contains a path and file name of a backup version selected by the background server according to a product type; and the device downloads a version file and reboots from the version file. The device, when finding during the boot that the file system is damaged, implements network communications between the foreground and the background prior to switching to a large version, in order to acquire a version from the background server actively and reload it, so that the damaged file system is self-repaired automatically without manual interference.
