[0045] In order to enable those skilled in the art to better understand the technical solutions of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0046] Based on at least one of the aforementioned technical problems, the present application provides a data recovery method, which is applied to an electronic device, wherein the hard disk of the electronic device includes at least a first partition and a second partition, a first operating system is installed in the first partition, and a second operating system is installed in the second partition; the method includes: receiving an interrupt signal during a basic input and output system process; based on the interrupt signal, starting the first operating system of the first partition; using the first operating system, based on the received instruction to download the second operating system image file, connecting to a wireless network to download the second operating system image file of a server; wherein the instruction to download the second operating system image file includes a network storage address of the second operating system image file; and using the acquired second operating system image file to recover the second operating system. The data recovery method of the embodiment of the present application receives an interrupt signal during the startup process of the basic input and output system, starts the first operating system of the first partition, connects to the network and downloads the second operating system image file based on the received instruction to download the second operating system image file, and uses the downloaded second operating system image file to recover the second operating system. The embodiment of the present application is applicable to terminal devices using wired networks (for example, desktop computers and industrial computers, etc.) or terminal devices using wireless networks (for example, laptops). It has strong versatility, can achieve accurate push, and can quickly restore the system when the terminal device system crashes, thereby improving the reliability of the system.

[0047] The data recovery method of the embodiment of the present application is applied to an electronic device, the hard disk of the electronic device at least includes a first partition and a second partition, a first operating system is installed in the first partition, and a second operating system is installed in the second partition. For example, the first operating system is a Linux system, and the second operating system is a Windows system.

[0048] The electronic devices in the embodiments of the present application may include portable electronic devices such as personal computers, laptops, tablet computers, mobile phones, digital cameras, personal digital assistants, game consoles, etc., and may also include large fixed electronic devices such as automatic teller machines (ATMs), etc. The embodiments of the present application are described using a laptop computer as an example.

[0049] In one embodiment of the present application, when the hard disk supports the Non Volatile Memory Host Controller Interface Specification (NVMe), the Non Volatile Memory Host Controller Interface Specification command is used to divide the hard disk into the first partition and the second partition. The first partition is a security partition, and the security partition can be set to a default invisible state to prevent the data in the security partition from being arbitrarily changed, thereby ensuring the security of the data. Of course, when necessary, the security partition can be set to a visible state to facilitate operations on the data in the security partition.

[0050] In the embodiment of the present application, when backing up and restoring data, the hard disk can be divided into a safe zone, and then the initial backup file can be stored in the safe zone. When the backup and recovery function needs to be executed, the safe zone is opened through the Basic Input Output System (BIOS), and the backup and recovery software is called to implement the data backup and recovery function.

[0051] For example, by defining the general NVMe protocol instructions and sending the control instructions, the SSD firmware can realize the establishment of the security partition in the SSD and the management of the visual state according to the specific values ​​of each parameter in the control instruction. It has high compatibility and versatility, supports all PCIe NVMe SSD devices, and realizes the user's demand for data protection. For example, for a 256G hard disk, the manufacturer sets the last 6G as the security zone through the NVMe protocol management tool, so that the partition software and BIOS cannot see the 6G partition, that is, the entire hard disk capacity is only displayed as 250G under the operating system and BIOS. In addition, the scheme of the embodiment of the present application can realize the deep protection of the data in the security partition, avoid the identification of third-party tools, and improve the security of the backup file; in addition, the method provided in the embodiment of the present application can be realized on the NVMe SSD layer, without relying on the operating system architecture or the central processing unit (CPU) platform, and has better universality.

[0052] Generally, the first partition can be allocated a smaller hard disk space as a security partition, and the second partition can be allocated a larger hard disk space as a common partition. For example, for a 512G hard disk, 500G hard disk space can be allocated as the second partition, and 12G hard disk space can be allocated as the first partition.

[0053] The embodiment of the present application is introduced by taking the Linux operating system as the first operating system as an example, and the second operating system may be Microsoft's Windows operating system.

[0054] In one example, the embodiment of the present application can install a simplified Linux operating system on the first partition. To reduce the size of the operating system, the simplified Linux operating system can only install necessary program software, such as desktop programs, network card drivers, etc.

[0055] Figure 1 A schematic flow chart of a data recovery method according to an embodiment of the present application is shown; Figure 1 As shown, the data recovery method 100 according to the embodiment of the present application may include the following steps S101, S102, S103 and S104:

[0056] In step S101, during the startup process of the Basic Input Output System (BIOS), an interrupt signal is received.

[0057] Typically, when an electronic device is turned on or restarted, a Basic Input Output System (BIOS) is started. During the process of starting the Basic Input Output System (BIOS), an interrupt signal can be sent to enter the first operating system. The interrupt signal can be sent by a user by pressing a key. For example, when an electronic device is turned on or restarted, during the startup process of the Basic Input Output System (BIOS), the user generates and sends an interrupt signal by pressing a hot key. After receiving the interrupt signal, the electronic device enters the secure partition and starts the first operating system. For example, the hot key can be a function key such as the "F2" function key, or a combination key.

[0058] In step S102, based on the interrupt signal, the first operating system of the first partition is started.

[0059] In one embodiment of the present application, Figure 2 As shown, the method further comprises step A1:

[0060] In step A1, when the interrupt signal is received, the basic input and output system uses a reserved custom field of the non-volatile memory host controller interface specification standard protocol (NVMe) to open the security partition and sets the security partition to a visible state.

[0061] During the startup process of the Basic Input Output System (BIOS), when an interrupt signal is received, the Basic Input Output System (BIOS) opens the security zone. For example, the BIOS uses an opening instruction of the NVMe standard protocol to set the security partition to a visible state.

[0062] In the embodiment of the present application, the data protection area is turned on or off by setting the first partition as a security partition (i.e., invisible to the host), so as to achieve the purpose of data protection based on user needs. When the user accesses the first partition, the first partition is set to a visible state for user convenience. In the specific implementation, for a solid-state drive that supports the non-volatile memory host controller interface specification standard protocol (NVMe), a general non-volatile memory host controller interface specification standard protocol (NVMe) instruction can be used to define and control the sending of instructions, so that the solid-state drive firmware can establish a security partition in the solid-state drive and manage the visible state according to the specific values ​​of each parameter in the control instruction. It has high compatibility and versatility, supports all solid-state drives (SSDs) SSD devices of the non-volatile memory host controller interface specification standard protocol (NVMe), and realizes the user's demand for data protection.

[0063] For example, for a 512G hard disk, the manufacturer sets the last 12G as a security zone through the Non-Volatile Memory Host Controller Interface Specification Standard Protocol (NVMe) management tool, so that the partitioning software and BIOS cannot see this 12G partition, that is, the entire hard disk capacity is only displayed as 500G under the operating system and BIOS. When the user needs to access this 12G security partition, the reserved custom field of the Non-Volatile Memory Host Controller Interface Specification Standard Protocol (NVMe) is used to open the 12G security partition and enter the first operating system for operation.

[0064] In one embodiment of the present application, Figure 3 As shown, the method further includes step B1 and step B2:

[0065] In step B1, when the first operating system is shut down, memory resources occupied by the first operating system are released;

[0066] In step B2, the first partition is set to an invisible state.

[0067] The embodiment of the present application sets the first partition to a default invisible state to prevent the data in the secure partition from being arbitrarily changed and ensure the security of the data. Of course, when necessary, the secure partition can be set to a visible state to facilitate operations on the data in the secure partition.

[0068] In step S103, using the first operating system, based on the received instruction to download the second operating system image file, connect to the wireless network to download the second operating system image file from the server; wherein the instruction to download the second operating system image file includes the network storage address of the second operating system image file.

[0069] The wireless network includes a local area network and / or the Internet. Since the first operating system has its own wired network card driver and wireless network card driver, the second operating system image file can also be downloaded through the network for a terminal device only equipped with a wireless network card.

[0070] like Figure 4 The figure shows the display interface presented after starting the first operating system. A "Mirror Download" button is displayed on the display interface. When the user presses the "Mirror Download" button, an instruction to download the second operating system image file is generated, and then the system downloads the image file based on the network download address of the second operating system image file.

[0071] Accordingly, if Figure 5 As shown, step S103 of connecting to the network and downloading the second operating system image file includes step C1 and step C2:

[0072] In step C1, an instruction to select one of the second operating system image files is received;

[0073] In step C2, based on the instruction to select one of the second operating system image files, one of the second operating system image files is downloaded.

[0074] In one embodiment of the present application, Figure 6 As shown, it is a schematic diagram of the second operating system image file download interface. The second operating system image file includes at least two versions of the second operating system image file. For example, the first version of the second operating system image file is a Windows 10 system, and the second version of the second operating system image file is a Windows 11 system. For another example, the first version of the second operating system image file is a professional version of Windows 10 system, and the second version of the second operating system image file is a home version of Windows 10 system. Users can download according to their needs.

[0075] like Figure 7 As shown, this is the display interface after the second operating system image file is downloaded and installed. After clicking the "Finish" button, the terminal device can be restarted to enter the second partition and start the second operating system.

[0076] In step S104, the second operating system is restored using the acquired second operating system image file.

[0077] The first partition also has a backup and recovery program installed, and the first partition and / or the second partition stores backup and recovery files.

[0078] In one embodiment of the present application, Figure 8 As shown, the method further includes the following steps D1, D2 or D3:

[0079] In step D1, using the first operating system, based on the received custom backup and recovery instruction, using the backup and recovery program and the backup and recovery file, the second operating system is custom restored;

[0080] In step D2, the second operating system is restored using the first operating system, based on the received operating system restoration instruction, the backup restoration program and the backup restoration file;

[0081] In step D3, the first operating system is used to restore the desktop cloud mode of the second operating system based on the received instruction to restore the desktop cloud mode, using the backup recovery program and the backup recovery file.

[0082] Continue to combine Figure 2 On the display interface, there are a custom backup and restore button, a restore operating system button, and a restore desktop cloud mode button. When the user chooses to press any of these buttons, the corresponding instruction is generated. Among them, the custom backup and restore button, the restore operating system button, and the restore desktop cloud mode button can be linked to the storage address of the local restore backup file.

[0083] For example, when the user presses a custom backup and restore button, the local restore backup file is called to perform system recovery, during which the user can customize the data or version information to be restored.

[0084] For another example, when the user presses the restore operating system button, the local restore backup file is called to perform system recovery to restore the entire operating system.

[0085] For another example, when the user presses the button to restore the desktop cloud mode, the local backup file is called to restore the system to restore the desktop cloud mode. The desktop cloud mode here is also called desktop virtualization and cloud computer, which is a new mode to replace traditional computers. After adopting the desktop cloud mode, users no longer need to buy a computer host. The CPU, memory, hard disk and other components contained in the host are all virtualized in the back-end server. A single high-performance server can virtualize 1-50 virtual hosts. The mainstream front-end device is to use a thin client (a device similar to a TV set-top box) to connect the display and keyboard and mouse. After the user installs the client, he accesses the virtual machine host on the back-end server through a unique communication protocol to achieve interactive operations and achieve the same experience as the computer. At the same time, the cloud desktop not only supports the replacement of traditional computers, but also supports other smart devices such as mobile phones and tablets to access on the Internet. It is also the latest solution for mobile office.

[0086] As for the backup recovery file, the generated backup recovery file can be stored in any specified location of the hard disk, for example, the first partition and / or the second partition. In the case where the first partition includes a plurality of sub-partitions, or the second partition includes a plurality of sub-partitions, the backup file can be stored in any one or more sub-partitions of the first partition, or the backup file can be stored in any one or more sub-partitions of the second partition.

[0087] In one embodiment of the present application, Fig. 9 As shown, the method further comprises step E1:

[0088] In step E1, during the startup of the basic input / output system, when the interrupt signal is not received, the second operating system installed in the second partition is started.

[0089] Generally speaking, by default, the electronic device directly starts the second operating system of the second partition after it is turned on. The second operating system installed in the second partition will only be started when, for example, an interrupt signal is received, an abnormality occurs when entering the first partition, resulting in the inability to access the first partition, or the first partition does not exist. This saves the waiting time of waiting for the user to issue an instruction to enter the second operating system every time the electronic device is turned on.

[0090] In one embodiment of the present application, Fig.10 As shown, the method further includes step F1, step F2 and step F3:

[0091] In step F1, during the startup of the basic input and output system, when the interrupt signal is received, it is detected whether there is a first partition; if the first partition exists, step F3 is executed, otherwise step F2 is executed

[0092] In step F2, in the absence of the first partition, starting the second operating system installed in the second partition;

[0093] In step F3, the first operating system of the first partition is started.

[0094] The actual step F3 is the above-mentioned step S102.

[0095] In another example of the present application, when the wireless network cannot be connected and a wired network exists, the first operating system can also be used to connect to the wired network to download the second operating system image file from the server based on the received instruction to download the second operating system image file, and then use the obtained second operating system image file to restore the second operating system.

[0096] The data recovery method of the embodiment of the present application receives an interrupt signal during the startup process of the basic input and output system, starts the first operating system of the first partition, connects to the network and downloads the second operating system image file based on the received instruction to download the second operating system image file, and uses the downloaded second operating system image file to recover the second operating system. The embodiment of the present application is applicable to terminal devices using wired networks (for example, desktop computers and industrial computers, etc.) or terminal devices using wireless networks (for example, laptops). It has strong versatility, can achieve accurate push, and can quickly restore the system when the terminal device system crashes, thereby improving the reliability of the system.

[0097] like Fig.11 , which is a schematic flow chart of a data recovery method according to another embodiment of the present application. The data recovery method 1100 according to the embodiment of the present application may include the following steps S1101, S1102, S1103, S1104 and S1105;

[0098] In step S1101, a terminal device is turned on, where the terminal device may be a desktop computer, a tablet computer, a notebook computer, or the like.

[0099] In step S1102, it is detected whether an interrupt instruction is received; if yes, step S1103 is executed; otherwise, step S1105 is executed. For example, a function key "F2" may be set, and when the function key "F2" is pressed during the system startup process, an interrupt instruction is generated.

[0100] In step S1103, check whether there is a secure partition; if so, execute step S1104; otherwise, execute step S1105.

[0101] In step S1104, the security zone partition is set to be visible, the Linux system in the security partition is started, the network is connected to download the client operating system image file, and the downloaded client operating system image file is used to perform the operation of restoring the client operating system.

[0102] In step S1105, the client operating system is started. For example, the client operating system is the Windows operating system of Microsoft Corporation.

[0103] The data recovery method of the embodiment of the present application receives an interrupt signal during the startup process of the basic input and output system, starts the first operating system of the first partition, connects to the network and downloads the second operating system image file based on the received instruction to download the second operating system image file, and uses the downloaded second operating system image file to recover the second operating system. The embodiment of the present application is applicable to terminal devices using wired networks (for example, desktop computers and industrial computers, etc.) or terminal devices using wireless networks (for example, laptops). It has strong versatility, can achieve accurate push, and can quickly restore the system when the terminal device system crashes, thereby improving the reliability of the system.
