When the operating system of the second terminal supports the fourth generation extended file system EXT4, the data of the first terminal user data area is sent to the second terminal through the USB flash drive communication protocol;

When the operating system of the second terminal does not support EXT4, the GPT (GUID Partition Table) of the first terminal storage area is sent to the second terminal through the USB flash drive communication protocol.

After the first terminal establishes a connection with the second terminal, the first terminal can determine the type of the operating system used by the second terminal according to the interaction instruction, that is, whether the second terminal can determine whether the second terminal is Support EXT4.

The solution provided in this embodiment can ensure that the user data can be obtained when the terminal cannot be powered on.

Second embodiment

In this embodiment, a terminal for backing up data is first described. The terminal includes two modules: an abnormality detecting module and a backup and recovery module, both of which belong to a startup code level, similar to a PC (Personal Computer) bios ( Basic Input Output System, basic input and output system). The abnormality detecting module may be configured to: detect whether the terminal is indeed unable to start, and only if the computer cannot be turned on continuously for several times, it is considered that the mobile phone cannot be started, and the user data needs to be backed up. The backup recovery module can be set to: copy user data to the PC through the USB flash drive mode.

The following describes the method provided in this embodiment by using the mobile terminal as an example in the embodiment:

Step 1: The mobile phone is turned on (for example, when the mobile phone power button is pressed, the triggered mobile phone is turned on), the abnormality detecting module starts the hardware watchdog timer, optionally, in this embodiment, the watchdog timing The timeout of the device can be set to 5 minutes;

Step 2: If the system starts normally during the timeout period, the abnormality detecting module turns off the watchdog timer and clears the number of restarts of the previously recorded mobile phone;

Step 3: If the watchdog timer expires, the mobile phone does not start normally, the abnormality detection module restarts the mobile phone, and records the number of times the mobile phone is restarted;

Step 4: Repeat the above process. If multiple restarts (more than one threshold, for example, six times, that is, the first preset number of times) cannot be turned on, it is determined that the mobile phone needs to back up data, and the abnormality detecting module restarts the mobile phone to enter the backup and recovery. Module

Step 5: The backup and recovery module prompts the user to enter the backup recovery mode by using a mobile phone motor vibration or an LCD (Liquid Crystal Display) display. For example, the mobile phone may be displayed on the LCD. Please enter the backup recovery mode and press Press the key + down key to confirm, prompt the user to enter the backup recovery mode, and wait for the user to confirm;

Step 6: The user confirms the backup by pressing the volume up key + down key, or after no operation timeout, for example, the user does not perform operation within 3 minutes, then enters the backup recovery mode;

Step 7. After the mobile phone is connected to the PC through a USB (Universal Serial Bus), the backup and recovery module enumerates the mobile phone into a USB flash drive;

Step 8: The user copies the USB flash drive data to the PC through the tool on the PC, thereby implementing backup data.

Third embodiment

This embodiment provides a data backup method, and FIG. 2 is a flowchart of the method. The method is substantially the same as the method provided by the second embodiment. The difference is that the method provided in this embodiment is performed on the mobile phone through the USB. After connecting with the PC, according to the type of operating system of the PC, the mobile phone is enumerated into a USB flash drive on the PC.

Optionally, in the case that the PC is a Linux operating system, since the Linux operating system supports the ext4 file system, and the mobile user data area is the ext4 file system, the user data area is directly enumerated on the Linux system through the USB flash drive communication protocol. A drive letter, the drive letter can be directly opened by double-clicking, thereby copying the data in the mobile phone, thereby realizing the backup of the mobile phone data.

In the case where the PC is a Windows operating system, since the Windows operating system does not support the ext4 file system by default, the above method cannot be used. The head of the mobile phone storage area stores a GPT partition table, which is used to describe the information of all the partitions on the mobile phone, and the windows system can recognize the partition table. So you can first report the partition table to the PC through the USB flash drive protocol, and then enumerate the entire partition into a drive letter on the Windows Windows system. At this time, if the user cannot double-click the drive letter, you can use the file on Windows. System tools, such as winhex, to open this drive letter, the file system tool can parse the information of each partition in multiple partitions, so that the data of the user data area can be copied out, thereby realizing the backup of the mobile phone data.
