The Memory 1005 may be a high-speed random access Memory (Random Access Memory, RAM) Memory or a stable nonvolatile Memory (NVM), such as a disk Memory. The memory 1005 may also optionally be a storage device separate from the processor 1001 described above.
Those skilled in the art will appreciate that the structure shown in fig. 1 is not limiting of the backup data reconstruction apparatus and may include more or fewer components than shown, or may combine certain components, or a different arrangement of components.
As shown in fig. 1, an operating system, a data storage module, a network communication module, a user interface module, and a backup data reconstruction program may be included in the memory 1005 as one type of storage medium.
In the backup data reconstruction device 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 backup data reconstruction device of the present invention may be disposed in the backup data reconstruction device, where the backup data reconstruction device invokes a backup data reconstruction program stored in the memory 1005 through the processor 1001, and executes the backup data reconstruction method provided by the embodiment of the present invention.
An embodiment of the present invention provides a backup data reconstruction method, and referring to fig. 2, fig. 2 is a schematic flow chart of a first embodiment of the backup data reconstruction method of the present invention.
In this embodiment, the backup data reconstruction method includes the following steps:
Step S10: and analyzing the backup data to be restored to determine the system volume data and the non-system volume data in the backup data to be restored.
It is to be understood that the execution body of the embodiment may be a backup data reconstruction device with functions of data processing, network communication, program running, and the like, or may be other computer devices with similar functions, and the backup data reconstruction device in the embodiment may be a backup program, and the backup program is taken as the execution body for illustration, which is not limited in this embodiment.
The backup program may backup metadata such as the operating system, applications, service data, partitions of the disk, volumes, and file systems of the computer to other computers.
In this embodiment, there are a source computer and a target computer, where the source computer and the target computer may be the same or different, and if the source computer and the target computer are different, the backup data to be restored is data backed up by all valid data on the disk of the source computer, including an operating system, an application program, service data of the source computer, and partition, volume, file system metadata of the disk, and so on.
It should be noted that, the system volume refers to a volume for storing a boot program, an operating system program, and an application program, such as a C disk and a reserved partition on Windows, and a boot partition and a root partition on Linux, and these volumes/partitions may be automatically created when the operating system is installed. The data on the system volume is typically relatively small.
Non-system volumes (also referred to as data volumes) refer to volumes on a computer other than system volumes, and after the system is installed, the user/administrator creates volumes/partitions for storing business data or material, such as windows' D-disk, E-disk, etc. The data on non-system volumes is typically relatively large.
In a specific implementation, when a source computer encounters a fault and a service system cannot be started, data backed up in advance needs to be restored to a target computer to reconstruct the service system, wherein the backup data needs to be analyzed before the data is restored to obtain system volume data, non-system volume data and the like.
Step S20: and acquiring storage information of the non-system volume data.
The storage information of the non-system volume data may be understood as a storage location of the non-system volume data on the disk in the backup data, and the like.
Step S30: and sending the storage information of the non-system volume data and the system volume data to a target computer so that the target computer runs an operating system based on the system volume data, and mounting the non-system volume in the operating system through the storage information to realize quick reconstruction of backup data.
Further, in order to quickly reconstruct backup data, storage information of non-system volume data and system volume data are sent to a target computer, so that the target computer runs an operating system based on the system volume data and mounts the non-system volume in the operating system through the storage information, so that quick reconstruction of the backup data can be realized. That is, previously disabled non-system services are re-enabled and all power-on auto-started services are re-started one pass. Since there is a dependency relationship in the service initiation, before the service is initiated, it is necessary to analyze the dependency relationship of the service and to preferentially initiate the dependent service.
After all the service programs are started, the service programs on the system can normally provide services to the outside, and the rest unreduced data can be recovered in the subsequent service providing process or when the system is idle.
In a specific implementation, when a source computer encounters a fault, and a service system cannot be started, data backed up in advance needs to be restored to a target computer, and the service system is rebuilt, wherein the backup data needs to be analyzed before being restored, a system volume is identified, and then the data of the system volume is restored to the target computer.
The method for identifying the system volumes is that some volumes in the backup data may be virtual volumes, such as logical volume management (Logical Volume Manager, lvm) of Linux, flexible raid, dynamic disks of microsoft Windows operating system (Microsoft Windows, windows), which are identified and assembled one by one, then the partition, the volume, the file system, which are identical to those of the original computer, are reassembled according to the partition, the volume, the file system metadata information of the disk in the backup data, and then the identification of the system volumes is started after the partition, the volume, the file system of the disk are assembled.
It should be noted that, the system of the target computer may be a Windows system, or may be a Linux system, where a system volume of Windows includes a msr partition, an esp partition, a system partition, and a reserved partition; the Linux system wraps map partitions, boot partitions, root partitions, and/etc,/home,/var directory dependent partitions, etc.
The processing manner of obtaining the disk partition, disk volume and disk file according to the system volume data may be that the disk partition metadata information, the disk volume metadata information and the disk file metadata information are obtained according to the system volume data, then the disk partition is recombined according to the disk partition metadata information, the disk volume is recombined according to the disk volume metadata information, the disk file is recombined according to the disk file metadata information, a target system volume is determined according to the disk partition information, the disk volume information and the disk file information, finally the system start configuration information and the registration service information of the target computer are obtained, the registration service information is identified, the system service information and the non-system service information are obtained, the non-system service information is disabled, and finally the system start configuration information is modified according to the target system volume and the non-system service information, and the target system configuration information is obtained.
In a specific implementation, after all system volumes are required to be identified, network configuration information of a target computer and disk area information of a non-system volume are acquired, the network configuration information and the disk area information are written into configuration files in the target system volume, then the network configuration information, the target system configuration information, storage information of the non-system volume data and the system volume data are sent to the target computer, so that the target computer runs an operating system based on the system volume data and the target system configuration information, and the target computer performs network configuration based on the network configuration information, when the network configuration is successful, a kernel restoration program enters a reconstruction state, and then the non-system volume is mounted in the operating system through the storage information, and the like, so that quick reconstruction of backup data is realized.
In this embodiment, the configuration of the system needs to be modified, otherwise, after the system volume is restored, the system may not work normally on the target computer. The step of modifying the configuration of the system includes disabling non-system services. Whether Windows or Linux systems, many services are registered, both with the system itself and with the application, which will run automatically after the system is started (and also manually, depending on the type of registered service). Since the first phase is to restore the system volumes only in full, the data of non-system volumes is not restored, if some service programs access the volumes, access failure occurs, and the service abnormality is caused, so that the problem does not occur after the service program is disabled.
The method for identifying the non-system service may be that all registered services are system services when the system is just installed, or else, are non-system services. When the configuration is modified, the non-system services are disabled so that the restored system will not start up when the non-system service program is started up.
The step of modifying the configuration of the system further includes hiding the non-system volume and disabling the automatic mounting of the non-system volume. Since the first phase is to restore the system volumes only in full, the data of non-system volumes is not restored, and if these volumes are to be mounted after the system is started, system startup failure may result. Hiding and disabling these non-system volumes, the presence of these volumes cannot be perceived at the time of the restored system startup (just as when the system was just installed), so it can be started up normally.
The network configuration information of the target computer and the disk area information of the non-system volume are acquired, and then the network configuration information and the disk area information are written into a configuration file in the target system volume, so that the network configuration information and the disk area information are needed to be used in the subsequent quick reconstruction.
After the configuration is revised, the data of all the system volumes are pushed to the target computer, and since the volume of data is not too large (substantially equivalent to the volume of data when the system was just installed), it does not take too much time.
After the system volume data is pushed, the disk area corresponding to the super block of the non-system volume is cleared on the target computer, so that the non-system volume is hidden. The target computer is then restarted, and the system is booted from the restored system volume after the start.
Because the system volume is restored in full quantity, complex network configuration such as connection with VPN or network card aggregation can be performed after the system is started, and after the network configuration is successful, the kernel restoration program can be connected to the backup server to quickly reconstruct the volume which is not restored.
The processing mode of the unreduced volume can be that all disk read-write operations of an operating system and an application program are captured, whether data of an operating disk area are restored or not is judged, if not, the data of the area are restored first, and then the disk read-write operations are carried out. Therefore, the operating system and the application program can normally access whether the data of the disk is restored or not.
After the kernel restore program enters a fast rebuilding state, extracting superblock data from the non-system volume data, and determining target storage position information corresponding to the superblock data, namely, reading the superblock data of all the non-system volumes from the backup server, writing the superblock data into the corresponding volumes, and after the superblock data is successfully written, notifying an operating system to rescan all the volume devices so as to activate the non-system volumes. At the same time, the automatic mounting function of the volumes is also started, and all non-system volumes are mounted on the corresponding paths, so that the application program can normally access the data on the volumes.
Further, to ensure that non-system services can operate properly, it is necessary to re-enable previously disabled non-system services and re-start all boot-up auto-started services once. Since there is a dependency relationship in the service initiation, before the service is initiated, it is necessary to analyze the dependency relationship of the service and to preferentially initiate the dependent service.
After all the service programs are started, the service programs on the system can normally provide services to the outside, and the rest unreduced data can be recovered in the subsequent service providing process or when the system is idle.
In this embodiment, the system volume in the backup data is identified, the data on the system volume is restored in full quantity, and after the system is started, the network configuration is successful, and then the data of the non-system volume is restored. During the data restoration, the business program on the system can be started normally and provide service to the outside. Because the system volume is restored in full quantity, a backup server is not required to be connected in the system starting process to restore data. After the system is started successfully, the network configuration is finished (the virtual private network (Virtual Private Network, VPN) is connected or network card aggregation is performed, etc.), and the rest data is quickly rebuilt. In general, the system volume data of the service system is not too large, which is basically equal to the data volume when the operating system is just installed (Linux system is generally smaller than 5GB and windows system is generally smaller than 30 GB), so that it does not take too much time to restore the data, but the data of the non-system is too large (in many cases, the data exceeds 1000 GB), and the restoration is time-consuming. Under the scene, the method of firstly restoring the system volume in full quantity and then quickly reconstructing the service data volume can also realize the quick reconstruction of the system service.
In this embodiment, the backup data to be restored is first analyzed to determine the system volume data and the non-system volume data in the backup data to be restored, then the storage information of the non-system volume data is obtained, and then the storage information of the non-system volume data and the system volume data are sent to the target computer, so that the target computer runs the operating system based on the system volume data, and the non-system volume data is mounted in the operating system through the storage information, so as to realize quick reconstruction of the backup data. In the prior art, full data recovery or rapid data recovery is needed, the full data recovery has low requirements on network environment, but the recovery service consumes long time, especially when the service data volume is large; the fast data recovery consumes short time, can restore the service and restore the data, but needs to complete network configuration in the early stage of system startup, otherwise, the later data recovery and service recovery cannot be performed, and the embodiment sends the storage information of the non-system volume data and the system volume data to the target computer, so that the target computer runs the operating system based on the system volume data, and mounts the non-system volume in the operating system through the storage information, thereby realizing the fast reconstruction of the backup data and further shortening the service system reconstruction period.
Referring to fig. 3, fig. 3 is a flowchart illustrating a second embodiment of a backup data reconstruction method according to the present invention.
Based on the first embodiment, in this embodiment, the step S30 further includes:
step S301: and performing system reorganization according to the system volume data to obtain disk partitions, disk volumes and disk files.
In a specific implementation, when a source computer encounters a fault, and a service system cannot be started, data backed up in advance needs to be restored to a target computer, and the service system is rebuilt, wherein the backup data needs to be analyzed before being restored, a system volume is identified, and then the data of the system volume is restored to the target computer.
The processing mode of identifying the system volume is that some volumes in the backup data can be virtual volumes, such as lvm, flexible raid and dynamic disk of Windows, which are identified and assembled one by one, and then the partition, the volume and the file system which are identical to those of the original computer are assembled according to the partition, the volume and the file system metadata information of the disk in the backup data.
Step S302: and determining a target system volume according to the disk partition, the disk volume and the disk file, and acquiring target system configuration information of a target computer according to the target system volume.
It should be noted that, the system of the target computer may be a Windows system, or may be a Linux system, where a system volume of Windows includes a msr partition, an esp partition, a system partition, and a reserved partition; the Linux system wraps map partitions, boot partitions, root partitions, and/etc,/home,/var directory dependent partitions, etc.
In this embodiment, the configuration of the system, that is, the system start configuration information of the target computer needs to be modified, otherwise, after the system volume is restored in full, the system may not work normally on the target computer. The step of modifying the configuration of the system includes disabling non-system services. Whether Windows or Linux systems, many services are registered, both with the system itself and with the application, which will run automatically after the system is started (and also manually, depending on the type of registered service). Since the first phase is to restore the system volumes only in full, the data of non-system volumes is not restored, if some service programs access the volumes, access failure occurs, and the service abnormality is caused, so that the problem does not occur after the service program is disabled.
When the configuration is modified, the non-system services are disabled so that the restored system will not start up when the non-system service program is started up.
The step of modifying the configuration of the system further includes hiding the non-system volume and disabling the automatic mounting of the non-system volume. Since the first phase is to restore the system volumes only in full, the data of non-system volumes is not restored, and if these volumes are to be mounted after the system is started, system startup failure may result. Hiding and disabling these non-system volumes, the presence of these volumes cannot be perceived at the time of the restored system startup (just as when the system was just installed), so it can be started up normally.
The network configuration information of the target computer and the disk area information of the non-system volume are acquired, and then the network configuration information and the disk area information are written into a configuration file in the target system volume, so that the network configuration information and the disk area information are needed to be used in the subsequent quick reconstruction.
Step S303: and sending the target system configuration information, the storage information of the non-system volume data and the system volume data to the target computer so that the target computer runs an operating system based on the system volume data and the target system configuration information, and mounting the non-system volume data in the operating system through the storage information to realize quick reconstruction of backup data.
After configuration is corrected, the target system configuration information, storage information of non-system volume data and system volume data are sent to the target computer, so that the target computer runs the operating system based on the system volume data and the target system configuration information, and as the volume data are not too large (basically equivalent to the volume data when the system is just installed), too much time is not consumed, and then the non-system volume data are mounted in the operating system through the storage information, so that quick reconstruction of backup data is realized.
In a specific implementation, after the system volume data is pushed, a disk area corresponding to a super block of the non-system volume is cleared on the target computer, so that the non-system volume is hidden. The target computer is then restarted, and the system is booted from the restored system volume after the start.
Because the system volume is restored in full quantity, complex network configuration such as connection with VPN or network card aggregation can be performed after the system is started, and after the network configuration is successful, the kernel restoration program can be connected to the backup server to quickly reconstruct the volume which is not restored.
The processing mode of the unreduced volume can be that all disk read-write operations of an operating system and an application program are captured, whether data of an operating disk area are restored or not is judged, if not, the data of the area are restored first, and then the disk read-write operations are carried out. Therefore, the operating system and the application program can normally access whether the data of the disk is restored or not.
After the kernel restore program enters a fast rebuilding state, extracting superblock data from the non-system volume data, and determining target storage position information corresponding to the superblock data, namely, reading the superblock data of all the non-system volumes from the backup server, writing the superblock data into the corresponding volumes, and after the superblock data is successfully written, notifying an operating system to rescan all the volume devices so as to activate the non-system volumes. At the same time, the automatic mounting function of the volumes is also started, and all non-system volumes are mounted on the corresponding paths, so that the application program can normally access the data on the volumes.
Further, to ensure that non-system services can operate properly, it is necessary to re-enable previously disabled non-system services and re-start all boot-up auto-started services once. Since there is a dependency relationship in the service initiation, before the service is initiated, it is necessary to analyze the dependency relationship of the service and to preferentially initiate the dependent service.
After all the service programs are started, the service programs on the system can normally provide services to the outside, and the rest unreduced data can be recovered in the subsequent service providing process or when the system is idle.
In this embodiment, system reorganization is performed according to system volume data to obtain a disk partition, a disk volume and a disk file, then a target system volume is determined according to the disk partition, the disk volume and the disk file, target system configuration information of a target computer is obtained according to the target system volume, then the target system configuration information, storage information of non-system volume data and the system volume data are sent to the target computer, so that the target computer runs an operating system based on the system volume data and the target system configuration information, and the non-system volume is mounted in the operating system through the storage information, so that quick reconstruction of backup data is achieved, and further a data recovery period is shortened.
