Embodiments of this application relate to the field of storage technologies, and disclose a data backup method and a terminal, to back up user data in a terminal when the terminal cannot be used. A specific solution is as follows: A terminal includes a first data partition, and the first data partition supports to start an operating system when the terminal is powered on. The terminal starts the operating system by using a second data partition after detecting a power-on failure of the terminal or detecting a preset operation of a user. The second data partition is a blank data partition. After the operating system is successfully started, the terminal transmits user data in the first data partition to a first storage medium. The first storage medium is located outside the terminal and is connected to the terminal.

User data backup to data partition of storage medium

Embodiments of this application provide a recovery method for a terminal device startup failure and a terminal device. The method includes: determining that a failure indication event occurs in a startup process, where the failure indication event is used to indicate a startup failure; determining at least one recovery policy based on a type of the failure indication event and/or a cause of the failure indication event; and performing startup recovery based on the at least one recovery policy.
