s101, receiving a recovery instruction, and reading backup user data in a preset recovery partition based on the recovery instruction.
Wherein, when the terminal is in a power-off state, the user generally presses two keys to trigger a recovery interface, for example: in the Android terminal with the Android operating system, a power key, a volume increasing key and a volume reducing key are arranged on the terminal, and when the terminal is in a power-off state, the time for pressing the power key and the volume reducing key by a user exceeds the preset time, the terminal can display a recovery interface. The user can operate on the recovery interface to generate a recovery instruction, and the terminal reads the backup user data stored in the preset recovery partition in response to the recovery instruction.
For example: as shown in fig. 2, the terminal is provided with a power key 20, a volume increasing key 21 and a volume decreasing key 22, when the terminal is in a power-off state and the duration of pressing the power key 20 and the volume decreasing key 22 by the terminal exceeds 3 seconds, the terminal displays a recovery interface, and the recovery interface includes 3 options: the method comprises the steps of restarting a boot loader, recovering user data and shutting down, wherein the restart boot loader is used for representing a bootloader of the restart terminal, the recovered user data represents user data which is backed up in the terminal in advance, and the shutting down represents the execution of shutting down operation. When the user clicks the option of 'recovering user data', the terminal receives the recovery instruction, and the terminal reads the backup user data in the recovery partition.
The terminal is preset with a recovery partition, the recovery partition is a physical partition of the terminal, the recovery partition is used for storing backup user data, the backup user data can be generated by real-time collection of a monitoring process in the terminal, the recovery partition corresponds to a mounting point, and the terminal reads the backup user data in the recovery partition through the mounting point. .

When the terminal leaves a factory, the versions of the system installation packages in the first system partition and the second system partition are the same, the terminal sets one partition of the first system partition and the second system partition as a main partition, and the other partition of the first system partition and the second system partition as a standby partition. For example: the terminal is provided with a partition a and a partition b, the versions of the system installation packages in the partition a and the partition b are the same, the partition a is a main partition, the partition b is a standby partition, and the terminal runs an operating system by using the partition a currently; when the terminal detects that the system installation package needs to be upgraded in the using process, the terminal downloads the system installation package of the new version into the partition b in an OTA mode, the system installation package of the old version in the partition b is covered, when the terminal finishes downloading, the terminal changes the partition b into the main partition and the partition a into the standby partition, and the terminal starts an operating system through the partition b.
The terminal determines a target system partition in the first system partition and the second system partition, and the selection mode may include: determining a target system partition in the first system partition and the second system partition based on a selection instruction of a user; or the operating system currently running at the terminal cannot run normally due to file damage or other reasons, the terminal stores the log file, determines that the main partition is abnormal according to the log file, and selects the standby partition of the two partitions as the target system partition.
