It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The user interface 1003 may include a Display screen (Display), an input unit such as a Keyboard (Keyboard), and the optional user interface 1003 may also include a standard wired interface, a wireless interface. The network interface 1004 may optionally include a standard wired interface, a Wireless interface (e.g., a Wireless-Fidelity (WI-FI) interface). The Memory 1005 may be a Random Access Memory (RAM) or a Non-Volatile Memory (NVM), such as a disk Memory. The memory 1005 may alternatively be a storage device separate from the processor 1001.
Those skilled in the art will appreciate that the configuration shown in fig. 1 does not constitute a limitation of the electronic device and may include more or fewer components than those shown, or some components may be combined, or a different arrangement of components.
As shown in fig. 1, a memory 1005, which is a storage medium, may include therein an operating system, a network communication module, a user interface module, and a business system backup program.
In the electronic apparatus shown in fig. 1, the network interface 1004 is mainly used for data communication with a network server; the user interface 1003 is mainly used for data interaction with a user; the processor 1001 and the memory 1005 in the electronic device of the present invention may be disposed in a service system synchronization device, and the electronic device calls a service system backup program stored in the memory 1005 through the processor 1001 and executes the service system synchronization method provided in the embodiment of the present invention.
An embodiment of the present invention provides a service system synchronization method, and referring to fig. 2, fig. 2 is a schematic flow diagram of a first embodiment of a service system synchronization method according to the present invention.
In this embodiment, the service system synchronization method includes the following steps:
step S10: and receiving system backup data of the main service system, which is sent by the backup server.
It should be noted that, the execution main body of this embodiment may be the service system synchronization device, and the service system synchronization device may be an electronic device such as a personal computer, a server, and the like, or may be other devices that can achieve the same or similar functions.
It should be noted that the backup server may be a server for managing backup data of the main business system. The system backup data may be complete machine backup data of a main service system at a certain time, and the complete machine backup data may include an operating system, an application program, service data of a computer, and metadata of a partition, a volume, a file system, and the like of a disk. The service system synchronization device may be a computer carrying the standby service system, or a computer connected to the standby service system and capable of controlling the standby service system. In this embodiment, the service system synchronization apparatus will be described by taking a computer equipped with a standby service system as an example. After the service system synchronization device receives the system backup data, it has a system which is the same as the main service system.
Step S20: and carrying out system initialization on the standby service system based on the system backup data.
It should be noted that some highly configured physical servers need to perform hardware initialization before starting the operating system, and this initialization process may be very long, requiring tens of minutes. If the main service system fails, the service switching is executed, the host of the standby service system is started, then the hardware initializes and starts the operating system, and the time is long, which is unacceptable for the service continuity. Because the host of the standby service system is started based on the backup data of the main service system, the operating system running on the host of the standby service system, that is, the operating system running on the host of the main service system, is the same as the software installed on the system.
Step S30: and when the system initialization reaches a preset stage, suspending the system initialization and acquiring the disk write-in data of the main service system.
It should be noted that the disk write data may be cdp (continuous data protection) data generated in the main service system after the generation time corresponding to the system backup data by the main service system.
In actual use, the main service system will continuously push the CDP data generated by the main service system to the backup server, so that the service system synchronization device can read the disk write data of the main service system from the backup server. Of course, the service system synchronization device may also be directly connected to the main service system, and then obtain the disk write data from the main service system.
It should be noted that, in general, the start-up procedure of the operating system, that is, the system initialization procedure, is generally as follows: the method comprises the steps that firstly, hardware self-checking is carried out, then a system bootstrap program on MBR is loaded and executed, the system bootstrap program is responsible for loading and operating a system bootstrap device, the system bootstrap device loads a kernel and a key driver program according to configuration, and gives an execution right of a CPU to an initialization program of the kernel, a user state process and a service system are started after the kernel is initialized, and if CDP data pushed by a backup server are received and written into a disk after the user state process is started after the kernel is initialized, the CDP data cannot be synchronized when partial data on the disk are loaded into a memory, and when corresponding data on the disk are modified subsequently, the data inconsistency can cause system abnormity, and an operating system can cause errors or crash.
In practical use, in order to avoid the problem of system crash, the system initialization needs to be stopped after the system initialization reaches a certain stage, so as to ensure that the error or crash of the operating system is avoided when the received CDP data is written into the disk. The preset stage may be determined by the behavior of the os mounting the system volume device.
Further, in order to ensure that the primary/standby service switching is performed as fast as possible when the primary service system fails, before step S30 in this embodiment, the method may further include:
monitoring an execution flow for carrying out system initialization on the standby service system in real time;
and when the execution flow reaches the state that the initialization of the system kernel structure is finished and the system volume equipment is to be mounted, judging that the initialization of the system reaches a preset stage.
It should be noted that, by analyzing and experimenting each stage of system startup, when the system initialization is completed to the initialization of the kernel structure and the system volume device is to be mounted at this stage, each important component in the operating system is initialized, such as the kernel data structure, the hardware plug and play manager, the network protocol stack, the storage protocol stack, and the like, the core function of the system kernel can already work normally, and at this time, the system volume device is not mounted, and at this time, when writing the CDP data into the disk, no system exception is caused, and the system initialization of the standby service system is suspended at this stage, so that the system initialization of the standby service system can be performed as much as possible without affecting the writing of the CDP data into the disk, so that the switching time is reduced as much as possible when the standby service is switched. Therefore, when the execution flow reaches the end of initialization of the system kernel structure and the system volume device is to be mounted, the system initialization is judged to reach the preset stage.
In actual use, the mounting behavior of the operating system on the system volume device can be monitored to determine the mounting behavior. When accessing the data of the volume device, the operating system needs to mount the volume device for accessing, so that whether the initialization of the system reaches a preset stage can be judged by monitoring the mounting operation behavior of the operating system on the volume device.
Step S40: and writing the disk write-in data into the disk of the standby service system so as to realize real-time synchronization of the disk data of the main service system.
It should be noted that, since the system initialization is performed on the standby service system based on the system backup data, it can be ensured that the system data and the state are consistent when the system backup data is generated by the standby service system and the main service system during the initialization, and then the disk write data is continuously received from the backup server and written into the disk of the standby service system, so that it can be ensured that the state of the standby service system is consistent with the state of the main service system at any time, thereby implementing the data synchronization with the main service system.
Further, since the whole system initialization process is not directly completed when the system initialization is performed on the standby service system, in order that the standby service system can normally take over the access request when the main service system fails, after step S40 in this embodiment, the method may further include:
when receiving a switching preparation instruction, acquiring a waiting event of the standby service system;
according to the waiting event, an initialization thread in the standby service system is awakened, and a subsequent process of system initialization is executed;
and when the system initialization is finished, switching the access request of the main service system to the standby service system.
It should be noted that the preparation switching instruction may be an instruction sent by the backup server to the service system synchronization device, or may be an instruction directly sent by another device to the service system synchronization device, for example: when the main service system fails, a manager sends a switching preparation instruction to the service system synchronization equipment through controlling the backup server, or directly sends the switching preparation instruction to the service system synchronization equipment through the management terminal.
It should be noted that the initialization thread may be a thread that performs system initialization on the standby service system, that is, the kernel of the operating system performs initialization (there may be multiple threads). The waiting event of the standby service system may be a waiting condition generated according to initialization when the system initialization of the standby service system is suspended, and for the operating system, the waiting event is a data structure, such as KEVENT of a Window kernel and wait _ queue _ head _ t of a Linux kernel.
In actual use, the standby event may be set to be a signal (a function call provided by an operating system such as a KeSetEvent, wake _ up … …, or the like), so as to wake up the initialization thread in the standby service system and resume running, thereby executing a subsequent process of performing system initialization on the standby service system, that is, a previous process in which system initialization is suspended, resulting in a process that is not executed completely.
It can be understood that the standby service system has the same data and system structure as the main service system after the system initialization is completed, and can provide the same service function as the main service system, so that the access request of the main service system can be directly switched to the standby service system, thereby realizing the switching of the main service and the standby service. In order to switch the access request of the main service system to the standby service system, only the service IP address of the main service system needs to be deleted, and the service IP address is configured to the standby service system.
The embodiment receives system backup data of a main service system sent by a backup server; performing system initialization on the standby service system based on the system backup data; suspending system initialization when the system initialization reaches a preset stage, and acquiring disk write-in data of a main service system from a backup server; and writing the disk write-in data into the disk of the standby service system so as to realize real-time synchronization of the disk data of the main service system. The backup service system is initialized according to the system backup data when the backup service system is constructed, and is suspended when the preset stage is reached, and then the disk write-in data of the main service system is synchronized to the backup service system.
Referring to fig. 3, fig. 3 is a flowchart illustrating a service system synchronization method according to a second embodiment of the present invention.
Based on the first embodiment, the step S30 of the service system synchronization method in this embodiment includes:
step S301: and when the system initialization reaches a preset stage, acquiring the operating system type of the standby service system.
It should be noted that the type of the operating system may be a type of an operating system installed in the standby service system (of course, the type of the operating system in the main service system may also be used), for example: windows or linux, etc.
In actual use, the operating system type of the standby service system can be determined by identifying the system kernel of the standby service system.
Step S302: and determining a system pause flow according to the type of the operating system.
It should be noted that the manner in which the operating systems of different operating system types are used to mount the system volume device may be different, and therefore, the initialization of the system needs to be suspended in a different manner.
For example: some operating systems notify the file system to execute the volume mount operation through an IOControlCode (an interactive mode of input and output control codes, application programs and operating system kernel modules), in this case, the behavior of the volume mount operation can be captured through a file system filter driver, and when the behavior occurs, the execution of a KeWaitForSingleObject and wait _ event _ interrupt series function is called to block the execution of the thread, so that the suspension of the system initialization is realized. Some operating systems mount volume devices through system calls, and can capture the behavior of the system mounting volume devices through the HOOK technology, and call series functions of kewaitforsingleibject and wait _ event _ interrupt to block the execution of threads (if a plurality of threads perform mounting operation, all threads are blocked one by one) so as to achieve the purpose of suspending the initialization of the system.
In actual use, a type flow mapping table may be pre-constructed, and system suspension flows corresponding to different operating system types are stored through the type flow mapping table, and then determining a system suspension flow according to an operating system type may be to search for a corresponding system suspension flow in the type flow mapping table according to the operating system type. The system pause process may be an operation process that needs to be executed to pause the system initialization.
Step S303: and suspending the system initialization of the standby service system according to the system suspension process.
It should be noted that, the suspending system initialization of the standby service system according to the system suspension flow is to capture the behavior of the system mount volume device through a file system filter driver or a HOOK system call, and then call a kewaitforsingleigleobject and wait _ event _ interrupt series function to block the execution of the system initialization thread, thereby achieving the purpose of suspending system initialization.
Step S304: and acquiring the disk write data of the main service system when the suspension is successful.
It can be understood that, when the initialization of the backup service system is suspended successfully, the service system synchronization device may initiate a request to the backup server, establish a connection with the backup server, and then read the disk write data of the main service system from the backup server according to the established connection, or receive the disk write data of the main service system pushed by the backup server according to the established connection. Of course, the disk write data may also be directly obtained from the main service system.
Further, since the operating system in the standby service system is in the initialization stage and many network communication modules of the system are not initialized yet, it may not be able to establish a connection with the backup server, and in order to ensure that the disk write data of the main service system can be normally acquired from the backup server, the step S304 in this embodiment may include:
when the suspension is successful, network configuration information is obtained;
performing network configuration on the standby service system according to the network configuration information;
when the network configuration is completed, establishing network connection with the backup server;
and acquiring the disk write-in data of the main service system from the backup server based on the network connection.
It should be noted that the network configuration information may be related data for configuring the network communication module. The network configuration data may be transmitted to the service system synchronization device by the backup server when transmitting the system backup data of the main service system, and the network configuration data may include data such as an IP address, a subnet mask, and an IP address of the backup server.
It can be understood that after the network configuration is completed, the backup service system has the capability of performing network communication to the outside, and therefore, a communication request can be initiated to the backup server, so as to establish network connection with the backup server, and then data interaction can be normally performed with the backup server according to the network connection, so as to read the disk write-in data of the main service system from the backup server, or receive the disk write-in data of the main service system pushed by the backup server.
Further, because the system initialization of the standby service system is not completed, and at this time, the system volume device in the standby service system is not mounted, and cannot directly read the network configuration information from the system volume device through the file system, that is, cannot read the network configuration information through the existing file read-write interface, but to ensure that the network configuration information can be obtained, when the network configuration information is stored in the standby service system, an unconventional means is used for storing, and correspondingly, when the network configuration information is obtained, a corresponding reading manner is also required to be used for reading, so the step of obtaining the network configuration information in this embodiment may include:
acquiring a preset configuration storage type;
determining a configuration information reading mode according to the preset configuration storage type in a preset configuration reading and writing rule;
and reading the network configuration information based on the configuration information reading mode.
It should be noted that the preset configuration storage type may be set by a manager of the service system synchronization device in advance according to actual needs, the preset configuration read-write rule may be a rule storing reading modes corresponding to various configuration storage types, a corresponding configuration information reading mode is searched for in the preset configuration read-write rule according to the preset configuration storage type, and then network configuration information is read according to the configuration information reading mode.
In practical use, different configuration storage types in the preset configuration read-write rule may correspond to different configuration information reading modes, for example:
A. when the network configuration information is stored, the configuration information is stored to a specific position by using the existing file read-write interface, such as C: \ network.cfg and/etc/network.cfg, all disks on a system are scanned when the system is initialized, partitions are activated according to partition tables of the disks, then the disk partitions are assembled into rolling equipment, codes are written to analyze file systems of all the rolling equipment, the distribution positions of the configuration files on the disks are obtained, and then the content in the configuration files is read by a method of directly reading the disks, so that the acquisition of the network configuration information is completed.
B. Some systems have initramfs (initram file system), and provide an environment of a simple file read-write interface at the early stage of system startup, so that configuration information in the system can be read through the existing file read-write interface. Therefore, the network configuration information can be stored in initramfs, which is specifically implemented by decompressing initrd.img corresponding to initramfs into a specific directory, then writing the configuration information into a file specific to the directory, and then compressing the directory into the original initrd.img. After the system is started and initrd.img is loaded into the memory, the configuration file can exist in initramfs, and the content of the configuration file can be read through a standard file read-write interface to complete the acquisition of network configuration information.
C. Windows registry profiles may hold configuration information and the configuration may be read at system initialization. The registry configuration file of the standby service system can be loaded, and the network configuration information is written into a specific position of the registry. After the system is initialized, the registry can be read through the registry read-write interface to obtain the network configuration information.
D. A part of space is reserved in a disk of the standby service system (a method of compressing a volume device or a method of pre-allocating a part of space in a volume device through a file system), then network configuration information is written into the reserved space, and the offset of the disk space is used as a starting parameter of the kernel main and standby disaster recovery modules. When the operating system is initialized, the contents in the configuration file can be read by directly reading the disk, and the acquisition of the network configuration information is completed.
Further, since the operating system is in the initialization stage, many network communication modules of the system are not initialized (for example, a network card driver may not be loaded, a TCP/IP protocol stack has not created a device object, and an interface layer module driver is not loaded), and network configuration cannot be directly performed (configuration failure or system deadlock may be caused), before configuring a network, it is necessary to trigger all components depending on network configuration and network communication to complete initialization in advance by an additional means, and therefore, the step of performing network configuration on the standby service system according to the network configuration information in this embodiment may include:
acquiring the equipment type and the operating system version of the standby service system;
acquiring a device driver corresponding to the device type, and acquiring a network component driver corresponding to the operating system version;
loading the device driver and the network component driver in the standby service system;
when the loading is finished, acquiring a network configuration interface corresponding to the operating system version;
and calling the network configuration interface to perform network configuration on the standby service system according to the network configuration information.
It should be noted that, the network card drivers used by different devices and different operating systems may be different, the drivers of components depending on network communication of different versions of operating systems may also be different, and corresponding network configuration methods are also different. Therefore, the device type and the operating system version of the network card on the host of the standby service system can be obtained, and then the corresponding network card driving program is obtained according to the device type and the operating system version and loaded into the operating system. And then acquiring the driver of the component depending on the network communication according to the version of the operating system, and loading the driver into the system.
