Description

Device and method for one-key recovery of computer system software

technical field

The invention relates to a one-key recovery device and method for computer system software, which is an electrical digital data processing device and method, and a recovery device and method for data failure of the electrical digital data processing device.

Background technique

Operating system crash is a very common computer system failure. For computer professionals or people with some computer knowledge, this is just a simple system recovery problem, but it is indeed a very difficult problem for most computer users. , especially for people whose work is completely dependent on computers and their networks, once the system crashes, the impact is very serious. Even if there is no system crash, a computer that is used for a long time will generate a lot of garbage, and the best way to remove this garbage is to reinstall the operating system. How to easily reinstall the operating system without any technical guidance is what most computer operators want without any computer professional background.

Existing computer operating systems can be recovered in a variety of ways, but there are still some problems, including:

1. The one-key recovery device of some computer systems uses the local storage space of the computer system as the backup space. When the space is damaged due to the partition table, file system super block, etc., the backup data cannot be recovered. Such as the Chinese patent "Computer System, Restoration Device and Restoration Method Based on One-Key Restoration Function" (application number 200610083036.6).

2. Another problem of local storage is that it is vulnerable to network attacks. Once the backup file is attacked and modified, even if the operating system is restored, it will still contain a virus, which will continue to pollute the reinstalled operating system.

3. The installation of some existing one-key recovery devices that are independent of the host is usually complicated, and it is necessary to modify the programs of the BIOS, South Bridge and other chips, which must be completed by computer professionals.

4. Almost all existing one-key recovery devices that are independent of the host are powered on when the host system is working, are closely related to the host, and cannot be simply plugged in or pulled out. That is to say, the one-key recovery device cannot be plugged and unplugged at will without professional knowledge. This not only consumes power, but also is a big limitation for non-professionals, making non-professionals afraid to restore the operating system by themselves.

The gate of the storage power supply MOS transistor Q2 is connected to the collector of the storage power supply switch tube Q4, and the base of the storage power supply switch tube Q4 is connected to the storage power supply maintenance terminal P3.5.

It should be noted that Fig. 1 is a typical circuit in which the control circuit chip is the single-chip microcomputer as the core, and the interface circuit is an example of a USB socket, configuration of corresponding capacitors, resistors and other original components. This embodiment is not limited to this configuration, and the control circuit may be other The control chip, such as MCU, etc., the interface circuit connected with the host, and the interface connected with the storage device, can be other types of interfaces.

One of the objectives of the present embodiment is to establish a device that can completely reinstall the computer operating system by the computer user without the need of others' guidance. To this end, this embodiment provides a button and five circuits: a control power supply circuit, a control circuit, a storage power supply circuit, an interface circuit, and a storage socket circuit. All that the user needs to operate is to plug the device into the host, start the computer, press the only operation key-press and hold it for a few seconds, and then select the operation to be performed through the screen and mouse of the host, such as the system Reinstallation or system backup, after that, no operation is required at all, and it is all done automatically.

The control circuit is an interface controller used to perform data transmission control on the interface circuit and the storage socket circuit. The interface circuit is used to communicate with the host, that is, it can be a USB plug circuit, or a PCI or PCI-E plug-in circuit, so that this embodiment finally produces a small box that can be directly inserted into the USB interface of the computer, or can be installed A dedicated launchpad on the back or front of the computer. In the control circuit, a special operating system recovery indicator light D2 can also be set, and the indicator light and the button SW1 can be set in one, that is, press the SW1 button, and the flashing of the button indicates the installation, backup or recovery of the operating system.

It should be noted that the host described in this embodiment may be a desktop computer, a notebook computer, a rack-mounted server, a blade server, and an electronic device with computing and storage functions such as a storage array installed in a cabinet.

The storage socket circuit is mainly used to plug U disk or other storage devices, such as mobile hard disks, etc. The storage device has built-in data backup and recovery software and the backup operating system or data. The backup operating system can be a Linux system, or Windows, Unix or other operating system. Using the one-key recovery device described in this embodiment does not require any modification to the operating system, boot mode, boot sector and BIOS firmware of the computer system of the host, and has no impact on the existing system software. Just modify the boot order of the BIOS to give priority to the one-key recovery device. In the case that the modification of the BIOS boot order is not allowed, you can also manually choose to boot from the one-key recovery device when the host starts up. If the device is in the form of a board, a common tool such as a screwdriver is required for installation. If it is in the form of a USB box, it can be used directly by plugging it into the USB interface of the host without any tools, which is very convenient.

In this embodiment, two sets of power supply circuits are used to supply power to the single-chip microcomputer and the storage device respectively. The control power supply circuit mainly supplies power to the control circuit, which is the key of this embodiment. The storage power supply circuit mainly supplies power to the storage socket circuit.

The control power supply circuit is provided with a button, which is responsible for the general start of the power supply, and a MOS tube Q1 to control the power supply of the switch control circuit (MCU U1), and a switch tube Q3 to control the gate of the MOS tube. After the host is powered on, before the button is pressed, the MOS transistors Q1 and Q2 are not turned on, so they do not supply power to the single-chip microcomputer, and of course, do not supply power to the connected storage device. At this time, the one-key recovery device and the storage device connected thereto are in a power-off state, and the power consumption is zero.

When the button is pressed and maintained, the Schottky diode D1 will conduct the gate of the control MOS transistor Q1 to the ground, so that the power bus of the interface circuit is connected to the VCC of the microcontroller, and the microcontroller is powered on. At the same time, the other input terminal of Schottky diode D1 conducts the delay start terminal P3.3 of the microcontroller U1 to the ground, so that the microcontroller delays timing. When the delay time is reached, the microcontroller triggers the process of supplying power to the USB storage device.

After the single-chip microcomputer runs, the single-chip microcomputer controls the switch tube Q3 to be turned on. After Q3 is turned on, the MOS tube Q1 is continuously turned on, so as to maintain the power supply of the single-chip microcomputer (even after the button is released, the single-chip microcomputer and the control circuit can maintain the power supply of the single-chip microcomputer), or you can According to the software setting, the power supply of the single-chip microcomputer is delayed and maintained (that is, the power supply of the single-chip microcomputer is still controlled by the button, and the power supply of the single-chip microcomputer is stopped when the button is released). The microcontroller can obtain the pressed state of the button through the Schottky diode D1.

The single-chip computer decides whether to supply power to the USB storage device according to the duration of the button pressing. The single-chip microcomputer is turned on through the switch tube Q4, and after the Q4 is turned on, the MOS tube Q2 is turned on, thereby controlling the power supply of the USB storage device.

The storage power supply circuit is mainly used to supply power to the control storage socket circuit. When the storage power supply maintenance terminal P3.5 of the microcontroller gives a high level, Q4 is turned on, so that the source and drain of Q2 are turned on, and the interface circuit is turned on. VBUS_IN is connected with VBUS_OUT of the storage socket circuit to supply power to the storage.

Embodiment 8:

This embodiment is a one-key recovery method for computer system software based on the device described in the foregoing embodiment. This embodiment includes: the normal working process of the host, the process of restoring the host system, and the process of backing up the host system. The normal working process of the host means that the host starts a normal operating system and executes normal services. In this case, the device may be connected to the host or not connected to the host. When the device is not connected to the host, the device is physically disconnected from the host, and the device is not powered on, so no working process will occur, and no virus will be attacked.

It should be noted that this embodiment is described by taking the single-chip microcomputer architecture of FIG. 1 as an example, and this embodiment is not limited to the single-chip microcomputer architecture.

When the host is working normally, if the device is plugged into the host, there are: the button SW1 is disconnected, the delay start terminal P3.3, the control power supply maintenance terminal P3.4, and the storage power supply maintenance terminal P3.5 are not available. The signal controls the power supply MOS transistor Q1 and the storage power supply MOS transistor Q2 to be in an off state, so that the control circuit is not powered on, so that neither the storage power supply circuit nor the storage socket circuit is powered on; the entire device is powered off. It can be seen from this that the device is in a power-off state at this time, the indicator light will not light up, the virus cannot invade, and the device is in a completely safe state.

The device startup methods for restoring the host operating system and the host operating system backup process are the same, except that two options are set for the operator to choose when loading the built-in data backup and recovery software to perform system recovery or system backup respectively, and can also be configured The default operation or process makes the operator do not need any operation after the key is disconnected, and the data backup and recovery software automatically completes the maintenance of the host system and shuts down according to the default operation or process. The specific process includes the following steps, as shown in Figure 2:

Step 1. Button triggering: Regardless of whether the host is powered on, first confirm whether the device is plugged into the host, and then start or restart the host after confirmation. When the host is powered on, immediately press the button SW1 and keep pressing.

The button SW1 is the only button of the device that needs to be operated. After confirming that the device is firmly plugged into the host, confirm whether the host is powered on. If the host is powered on, it will be restarted, and if the host is powered off, the host will be powered on. The purpose of startup is to enable the built-in boot program of the device to automatically guide the data backup and recovery software into the host system maintenance state. It should be noted that the host BIOS should be in a state where the plug interface between the device and the host is the preferred choice. That is: if the interface is USB, the host BIOS will give priority to USB, and if the interface is PCI or PCI-E, it will give priority to PCI or PCI-E.

Step 2: Temporary power supply: During the period when the button is maintained and pressed, the Schottky diode is turned on to control the power supply MOS transistor Q1 and the delay start terminal P3.3 to trigger the control circuit; the control power supply MOS transistor Q1 turns on the bus input terminal and the high-end power supply , so that the host power supply supplies power to the control circuit, and the control circuit is turned on after a delay time, and the indicator light D2 starts to flash rapidly.

Temporary power supply mainly connects the control power supply circuit with the power supply of the host, and triggers the control circuit. For safety reasons, a delay trigger can be set. For example, press the button for 3-6 seconds, and then trigger the control circuit. You can also press the button without setting the delay. Directly trigger the power supply circuit. In order to distinguish it from the startup state and the working state, the change of the indicator light can be set. For example, you can set the indicator light to flash quickly to indicate the startup state, and to flash slowly or constantly to indicate the working status. Two-color indicator lights can also be used to indicate different working states. The button turns on one input terminal of Schottky diode D1 and conducts to ground, so that the gate of the control power MOS transistor Q1 is conducted to ground, and the low level of the gate of Q1 makes the source and drain of Q1 conduct, also That is, the single-chip microcomputer of the control circuit is connected to the power supply of the host computer, and the single-chip microcomputer is powered on. At the same time, the other input end of the Schottky diode outputs the trigger level to the microcontroller U1, so that the microcontroller triggers and enters the delayed start state.

Step 3, normal power supply start: after the delay expires, the control circuit sends a conduction level to the control power supply switch tube Q3 and the storage power supply switch tube Q4, so that the control power supply switch tube Q3 and the storage power supply switch tube Q4 are turned on, resulting in The control power supply MOS tube and the storage power supply MOS tube are turned on to supply power to the control circuit, the storage socket circuit and the storage device plugged into the USB socket, and the indicator light D2 continues to flash rapidly.

When the control circuit is started, the control circuit sends a high level to the bases of the switching tubes Q3 and Q4 of the control power supply circuit and the storage power supply circuit through the control power supply maintenance terminal P3.4 and the storage power supply maintenance terminal P3.5, so that Q3 and Q4 The collector is turned on to the ground, which leads to the conduction of Q1 and Q2, so that the power supply of the host is connected to the control power supply circuit and the storage power supply circuit and supplies power.

Step 4: Temporary power supply disconnection: After the control circuit, the storage socket circuit and the storage device are powered on, the indicator light starts to flash slowly, and the button is disconnected; The conduction level of the switch tube Q4 keeps the control power supply switch tube Q3 and the storage power supply switch tube Q4 turned on, thereby maintaining the conduction of the control power supply MOS tube Q1 and the storage power supply MOS tube Q3, and thus maintaining the control circuit, Storage socket circuits, power supply to storage devices.

Since the single-chip microcomputer U1 has been started, it continuously maintains the conduction signal of the control power supply maintenance terminal P3.4 and the storage power supply maintenance terminal P3.5, so that Q3 and Q4 are kept on, so as to maintain the conduction of Q1 and Q2, which is used to control the power supply circuit. Continuous power supply with the storage power supply circuit, temporary power supply is meaningless, then you can release the press button SW1, disconnect the Schottky diode D1 power supply to the control power supply circuit, then the host power supply continues to supply the control circuit and the storage device normally.

Step 5, host system maintenance: Since the control circuit, interface circuit, storage socket circuit and the storage device plugged into the USB socket are continuously powered on, the BIOS of the host can find the built-in boot program stored in the storage device, thereby starting the host computer. A restore or backup operation of the operating system.

Host system maintenance consists of two operations: restoring the operating system and backing up the existing operating system. The backup operating system stored in the storage device described in this embodiment refers to an operating system that includes a basic operating system, common application software, and corresponding settings. Generally speaking, restoring the operating system refers to reinstalling the operating system and simultaneously installing some common application software and some conventional system settings, rather than simply installing the operating system.

Step 6: Complete disconnection: After the recovery operation or backup operation of the host operating system is completed, or long press the button to disconnect the device from the host; or turn off the host and restart the host, the button remains disconnected, and the host cannot connect to the host. The control circuit supplies power, thereby de-energizing the device and disconnecting it from the host; or shutting down the host and unplugging the device from the host to physically disconnect the device.

After the operating system is installed or backed up, both the host and the one-key recovery device are powered on. For safety reasons, the host and the one-key recovery device need to be disconnected. There are three ways of disconnection: disconnection by long pressing the button, disconnection by restarting the host, and physical disconnection. A long-press program can be set in the single-chip microcomputer. When the device is powered on, long-pressing the button can disconnect the power supply of the device from the power supply of the host, so that the one-key recovery device is powered off and the long-pressing button is disconnected. The disconnection of restarting the host is to directly shut down the host after the host is installed or backed up. After the host is powered off, the host power supply cannot maintain the power supply of the control circuit, and the single-chip microcomputer cannot run due to power loss. The control power supply maintenance terminal P3.4 and the storage power supply maintain There is no signal at the terminal P3.5, so that the storage power supply MOS transistor Q3 and the storage power supply switch transistor Q4 are turned off, so that the control power supply MOS transistor Q1 and the storage power supply MOS transistor Q2 are turned off, and the one-key recovery device returns to the initial off state. Once the host is started, as long as the button SW1 is not pressed, the entire one-key recovery device will not be powered on, and will automatically disconnect from the host to realize the disconnection of the restarting host. When the host is turned off, the one-key recovery device can be directly removed from the host to achieve physical disconnection.

Embodiment 9:

This embodiment is an improvement of the eighth embodiment, and is a refinement of the disconnection of the long-press button described in the eighth embodiment. The disconnection of the long-pressed button in this embodiment includes: during the period when the button is maintained and pressed, the Schottky diode conducts the delay start terminal P3.3 of the single-chip microcomputer to the ground, so that the control circuit is turned on after a delay time, and the indicator light starts quickly. Blinking; after the delay expires, the control circuit sends a turn-off level to the control power supply switch Q3 and the storage power supply switch Q4, so that the control power supply switch Q3 and the storage power supply switch Q4 are turned off, resulting in the storage power supply MOS tube Q2. When the power is turned off, the storage socket circuit and the storage device plugged into the USB socket lose power. Since the Schottky diode continues to conduct the control power supply MOS transistor Q1 during the period when the key is maintained and pressed, the control power supply MOS transistor Q1 continues to connect the bus input terminal and the high-end power supply. It is turned on, so that the host power supply maintains power supply to the control circuit, and the indicator light continues to flash rapidly; after the storage socket circuit and the storage device lose power, the indicator light is always on for a certain period of time and then goes out, and the button is disconnected; after the button is disconnected, the Schottky diode The control power supply MOS transistor Q1 is turned off, thereby turning off the power supply of the control circuit, and the whole device is in a power-off state.

This embodiment is carried out under the condition that the host computer and the one-key recovery device are connected together and powered on at the same time. A delay opening program and a delay closing program are set in the single-chip microcomputer at the same time. When the one-key recovery device is in an overall power-off state, pressing the button will start the delay opening program. When the one-key recovery device is in a power-on state as a whole , press the button to start the delay shutdown program, in this embodiment, the startup and shutdown are both undertaken by the delay startup terminal P3.3 of the single-chip microcomputer.

Embodiment ten:

This embodiment is an improvement of the ninth embodiment, and is a refinement of the backup process of the ninth embodiment. When the operating system backup process described in this embodiment starts, the built-in boot program guides the data backup and recovery software to run, the data backup and recovery software prompts to select the hard disk data to be backed up, and automatically backs up the specified hard disk data to the storage device. There are two areas in the storage device: FAT32 partition for storing bootloader and data backup and recovery software and ext4 partition for storing backup data. The backup files of the host are stored in the storage device in the form of gzip compression, and the backup time is recorded at the same time.

The storage device described in this embodiment has a built-in independent boot program and an operating system, and does not depend on the operating system and software installed in the host. Even if the host's operating system and software completely crash, it will not affect the operation of the one-key recovery program.

There are two partitions in the USB storage device. The first partition is a FAT32 partition, which is used to store the FAT32 partition of the boot program and data backup and recovery software, and the second partition is an ext4 partition, which is used to store the backup data of the computer system.

The storage area of the storage device can store the factory-set computer system hard disk backup files in advance. The storage device can automatically restore the data of the host hard disk or RAID group (redundant disk array of independent disks) through software without human intervention, or manually select or confirm the hard disk or RAID group that needs to be backed up and restored through the mouse and keyboard.

During data backup or restoration, a progress bar, elapsed time and estimated remaining time can be displayed on the display for the operator's reference. The data backup and recovery software in the storage device can backup and restore the computer system hard disk and data hard disk in the form of a complete image of the block device, and can also use the file copy method to back up and restore. The backup files of the host are stored in the storage device in the form of gzip compression, and the backup time is recorded at the same time.

The large-capacity hard disks or large-capacity RAID groups in the computer system can be shielded through software settings, and for large-capacity storage systems, the backup files of the system disk can be prevented from being restored to the data disk by mistake.

Every backup and recovery operation is logged in the storage device to avoid disputes caused by misoperation.

Finally, it should be noted that the above is only used to illustrate the technical solution of the present invention and not to limit it. Although the present invention has been described in detail with reference to the preferred arrangement solution, those of ordinary skill in the art should understand that the technical solution of the present invention (such as The overall layout of the circuit, the application of various interfaces, the connection of various circuit elements, the sequence of steps, etc.) can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention.
