The Memory 1005 may be a Random Access Memory (RAM) Memory, or may be 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 backup data reconstruction device, and may include more or fewer components than shown, or some components in combination, or a different arrangement of components.
As shown in fig. 1, the memory 1005, which is a storage medium, may include therein an operating system, a data storage module, a network communication module, a user interface module, and a backup data reconstruction program.

An embodiment of the present invention provides a backup data reconstruction method, and referring to fig. 2, fig. 2 is a schematic flowchart of a backup data reconstruction method according to a first embodiment 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 system volume data and non-system volume data in the backup data to be restored.
It is easy to understand that the execution main body of the embodiment may be a backup data reconstruction device having functions of data processing, network communication, program operation, and the like, or may also be other computer devices having 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 main body for illustration, which is not limited in the embodiment.
The backup program can backup the operating system, application programs, service data, and metadata of the partition, volume, file system, etc. of the computer to other computers.
In this embodiment, a source computer and a target computer also exist, where the source computer and the target computer may be the same or different, and if the source computer is different from the target computer, the data to be restored and backed up is data backed up by all valid data on a disk of the source computer, including an operating system, an application program, and service data of the source computer, and partition, volume, and file system metadata of the disk.
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 in Windows, a boot partition and a root partition in Linux, and these volumes/partitions are automatically created when the operating system is installed. The data on the system volumes is typically relatively small.
The non-system volume (also referred to as a data volume) refers to a volume on a computer except for a system volume, and a user/administrator creates a volume/partition by himself after the system is installed, and the volume/partition is used for storing service data or materials, such as a D disk and an E disk of windows. Data on non-system volumes is typically 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 rebuild the service system, wherein the backed-up data needs to be analyzed before data restoration is performed to obtain system volume data, non-system volume data and the like.
Step S20: and acquiring the storage information of the non-system volume data.
The storage information of the non-system volume data can be understood as the storage location of the non-system volume data on the disk in the backup data.
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 the rapid reconstruction of the backup data.
Further, in order to perform fast reconstruction on the backup data, the step of sending 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 mounting the non-system volume in the operating system through the storage information to achieve fast reconstruction of the backup data may be that system reorganization is performed according to the system volume data to obtain the disk partition, the disk volume and the disk file, then the target system volume is determined according to the disk partition, the disk volume and the disk file, and the target system configuration information of the target computer is obtained according to the target system volume, and then the target system configuration information, 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 target system configuration information, and mounting the non-system volume in the operating system through the storage information to realize the rapid reconstruction of the backup data, generating a service starting instruction according to the non-system service information after the system enters a rapid reconstruction state, and sending the service starting instruction to the target computer so as to enable the target computer to start the non-system service according to the service starting instruction. That is, previously disabled non-system services are re-enabled and all power-on auto-initiated services are re-enabled. Since there is a dependency relationship in the starting of the service, before the service is started, the dependency relationship of the service needs to be analyzed, and the dependent service needs to be started preferentially.
After all the service programs are started, the service programs on the system can normally provide services to the outside, and the remaining 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 business system cannot be started, data backed up in advance needs to be restored to a target computer to rebuild the business system, wherein before the backup data is restored, the backup data needs to be analyzed to identify a system volume, and then all data of the system volume needs to be restored to the target computer.
The process of identifying the system Volume is that some volumes in the backup data may be virtual volumes, such as Logical Volume Manager (lvm) of Linux, soft raid, and dynamic disks of Microsoft Windows operating system (Microsoft Windows, Windows), which are all identified and assembled one by one, then partitions, volumes, and file systems that are the same as those of the original computer are reassembled according to metadata information of partitions, volumes, and file systems of the disks in the backup data, and then the system Volume is identified after the partitions, volumes, and file systems of the disks are assembled.
It should be noted that the system of the target computer may be a Windows system, a Linux system, and the like, where the system volume of Windows includes msr partition, esp partition, system partition, and reserved partition; the system volume of Linux comprises an esp partition, a boot partition, a root partition, and/etc., directory-dependent partitions such as/etc.,/home,/var, etc.
It should be further noted that the processing method for performing system restructuring according to the system volume data to obtain the disk partition, the disk volume, and the disk file may be that obtaining the metadata information of the disk partition, the metadata information of the disk volume, and the metadata information of the disk file according to the system volume data, then restructuring the disk partition according to the metadata information of the disk partition, restructuring the disk volume according to the metadata information of the disk volume, determining the target system volume according to the metadata information of the disk partition, the metadata information of the disk volume, and the information of the disk file, finally obtaining the system startup configuration information and the registration service information of the target computer, identifying the registration service information, obtaining the system service information and the non-system service information, disabling the non-system service information, and finally modifying the system startup configuration information according to the target system volume and the non-system service information, obtain target system configuration information, and the like.
In the specific implementation, after all system volumes need to be identified, network configuration information of a target computer and disk area information of non-system volumes are acquired, the network configuration information and the disk area information are written into a configuration file in the target system volume, then the network configuration information, 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 an operating system based on the system volume data and the target system configuration information, the target computer performs network configuration based on the network configuration information, when the network configuration is successful, a kernel restoring program enters a reconstruction state, and then the non-system volumes are mounted in the operating system through the storage information, so that rapid reconstruction of backup data is achieved.
In this embodiment, the configuration of the system needs to be modified, otherwise, after the system volume is completely 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. Regardless of the Windows or Linux system, many services are registered, both for the system itself and for applications, and these services run automatically after the system is started (and some are started manually, depending on the type of service registered). Because the system volume is only fully restored in the first stage, the data of the non-system volume is not restored, if some service programs access the volumes, the access fails, so that the service exception is caused, and the problem cannot occur after the service programs are forbidden.
The method of identifying non-system services may be that all registered services are system services when the system is just installed, and otherwise are non-system services. When the configuration is modified, the non-system services are disabled, so that the non-system service programs cannot be started when the restored system is started.
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 stage is only to restore the system volumes in full, the data of the non-system volumes is not restored, and if the system is mounted after starting, the system may fail to start. The non-system volumes are hidden and disabled, and when the restored system is started, the existence of the volumes cannot be sensed (just like the system is installed), so that the system can be started normally.
Network configuration information of a target computer and disk area information of a non-system volume are also required to be obtained, and then the network configuration information and the disk area information are written into a configuration file in the target system volume and are required to be used in subsequent quick reconstruction.
After the configuration is corrected, the data for all system volumes is pushed to the target computer, and since the data volume for these volumes is not too large (substantially equivalent to the data volume when the system was just installed), it does not take too much time.
After the data of the system volume is pushed, the disk area corresponding to the super block of the non-system volume is cleared on the target computer to realize the hiding of the non-system volume. The target computer is then restarted, and after startup the system is booted from the restored system volume.
Because the system volume is completely restored, the system can be subjected to complex network configuration after being started, such as VPN connection or network card aggregation, and after the network configuration is successful, the kernel restoring program can be connected to the backup server to quickly rebuild the volume which is not restored.
The volume that has not been restored can be processed by capturing all disk read-write operations of the operating system and the application program, determining whether the data in the operating disk area has been restored, if not, restoring the data in the area first, and then releasing the read-write operations of the disk. Therefore, the operating system and the application program can normally access the data of the disk regardless of whether the data of the disk is restored or not.
After the kernel restore program enters a fast rebuilding state, superblock data is extracted from the non-system volume data, target storage position information corresponding to the superblock data is determined, namely superblock data of all non-system volumes are read back from the backup server and written into corresponding volumes, and after the superblock data are successfully written, an operating system is informed to rescan all volume devices to activate the non-system volumes. Meanwhile, the automatic mounting function of the volume 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, in order to ensure that the non-system services can operate normally, the previously disabled non-system services need to be re-enabled, and all the services started automatically after the boot process need to be re-enabled. Since there is a dependency relationship in the starting of the service, before the service is started, the dependency relationship of the service needs to be analyzed, and the dependent service needs to be started preferentially.
After all the service programs are started, the service programs on the system can normally provide services to the outside, and the remaining unreduced data can be recovered in the subsequent service providing process or when the system is idle.
In this embodiment, the data on the system volume is fully restored by identifying the system volume in the backup data, 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 restoring process, the business program on the system can be started normally and provide service to the outside. Because the system volume is completely restored, a backup server does not need to be connected in the starting process of the system to restore the data. After the system is successfully started and the Network configuration is finished (Virtual Private Network (VPN) connection or Network card aggregation is performed, etc.), the remaining data is quickly reconstructed. In general, the system volume data of the business system is not too large, which is substantially equal to the data volume when the operating system is just installed (Linux system is generally less than 5GB, and Windows system is generally less than 30GB), so that it does not take too much time to restore the data, while the non-system data is large (often more than 1000GB), which is time-consuming to restore. In this scenario, the method of restoring the system volume in full first and then rapidly reconstructing the service data volume may also achieve rapid reconstruction of the system service.
In this embodiment, first, to-be-restored backup data is analyzed to determine system volume data and non-system volume data in the to-be-restored backup data, then storage information of the non-system volume data is acquired, and then the storage information of the non-system volume data and the 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 the non-system volume data is mounted in the operating system through the storage information, so as to realize rapid reconstruction of the backup data. In the prior art, full data recovery or rapid data recovery is required, the requirement of the full data recovery on a network environment is low, but the time for recovering services is long, especially when the service data volume is large; 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 an operating system based on the system volume data, and mounts the non-system volume in the operating system through the storage information to realize the rapid reconstruction of the backup data, thereby shortening the reconstruction period of the service system.
Referring to fig. 3, fig. 3 is a flowchart illustrating a backup data rebuilding method according to a second embodiment of the present invention.
Based on the first embodiment, in this embodiment, the step S30 further includes:
step S301: and performing system recombination according to the system volume data to obtain a disk partition, a disk volume and a disk file.
In a specific implementation, when a source computer encounters a fault and a business system cannot be started, data backed up in advance needs to be restored to a target computer to rebuild the business system, wherein before the backup data is restored, the backup data needs to be analyzed to identify a system volume, and then all data of the system volume needs to be restored to the target computer.
The process of identifying the system volume is that some volumes in the backup data may be virtual volumes, such as lvm of Linux, soft raid, and dynamic disk of Windows, which are identified and assembled one by one, and then, according to the metadata information of the partition, volume, and file system of the disk in the backup data, the partition, volume, and file system that are the same as those of the original computer are reassembled.
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, a Linux system, and the like, where the system volume of Windows includes msr partition, esp partition, system partition, and reserved partition; the system volume of Linux comprises an esp partition, a boot partition, a root partition, and/etc., directory-dependent partitions such as/etc.,/home,/var, etc.
In this embodiment, the configuration of the system, that is, the system startup configuration information of the target computer, needs to be modified, otherwise, after the system volume is completely 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. Regardless of the Windows or Linux system, many services are registered, both for the system itself and for applications, and these services run automatically after the system is started (and some are started manually, depending on the type of service registered). Because the system volume is only fully restored in the first stage, the data of the non-system volume is not restored, if some service programs access the volumes, the access fails, so that the service exception is caused, and the problem cannot occur after the service programs are forbidden.
When the configuration is modified, the non-system services are disabled, so that the non-system service programs cannot be started when the restored system is started.
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 stage is only to restore the system volumes in full, the data of the non-system volumes is not restored, and if the system is mounted after starting, the system may fail to start. The non-system volumes are hidden and disabled, and when the restored system is started, the existence of the volumes cannot be sensed (just like the system is installed), so that the system can be started normally.
Network configuration information of a target computer and disk area information of a non-system volume are also required to be obtained, and then the network configuration information and the disk area information are written into a configuration file in the target system volume and are required to be used in 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 mounts the non-system volume data in the operating system through the storage information, thereby realizing the rapid reconstruction of the backup data.
After the configuration is corrected, the target system configuration information, 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 an operating system based on the system volume data and the target system configuration information, since the data volume of the volumes is not too large (basically equal to the data volume 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 the backup data are quickly rebuilt.
In a specific implementation, after the data of the system volume is pushed, a disk area corresponding to a super block of the non-system volume is cleared on the target computer, so as to hide the non-system volume. The target computer is then restarted, and after startup the system is booted from the restored system volume.
Because the system volume is completely restored, the system can be subjected to complex network configuration after being started, such as VPN connection or network card aggregation, and after the network configuration is successful, the kernel restoring program can be connected to the backup server to quickly rebuild the volume which is not restored.
The volume that has not been restored can be processed by capturing all disk read-write operations of the operating system and the application program, determining whether the data in the operating disk area has been restored, if not, restoring the data in the area first, and then releasing the read-write operations of the disk. Therefore, the operating system and the application program can normally access the data of the disk regardless of whether the data of the disk is restored or not.
After the kernel restore program enters a fast rebuilding state, superblock data is extracted from the non-system volume data, target storage position information corresponding to the superblock data is determined, namely superblock data of all non-system volumes are read back from the backup server and written into corresponding volumes, and after the superblock data are successfully written, an operating system is informed to rescan all volume devices to activate the non-system volumes. Meanwhile, the automatic mounting function of the volume 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, in order to ensure that the non-system services can operate normally, the previously disabled non-system services need to be re-enabled, and all the services started automatically after the boot process need to be re-enabled. Since there is a dependency relationship in the starting of the service, before the service is started, the dependency relationship of the service needs to be analyzed, and the dependent service needs to be started preferentially.
After all the service programs are started, the service programs on the system can normally provide services to the outside, and the remaining unreduced data can be recovered in the subsequent service providing process or when the system is idle.
