Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method, an apparatus, a device, and a medium for recovering an operating system.
Background
In the prior art, backup and recovery of an operating system, including protection of configuration information and installed program files in the operating system, are generally divided into two ways:
first, file-based backup restore: and backing up the files, namely backing up the phase files in the operating system integrally according to a directory structure.
When the system is damaged due to failure and needs to be recovered, firstly, reinstalling operating system software which is consistent with the original operating system platform and version on the hardware host under the condition of preparing the required hardware host, and completing operations such as patch installation; and then corresponding backup software is deployed, the data to be backed up of the original operating system is read through the backup software, each file in the backed up operating system is restored to the reinstalled operating system through a network link, and finally the restoration of the whole system is completed.
Secondly, back-up based on bare metal is recovered: when backing up the operating system, collecting the information related to the operating system, such as partition information of a disk, configuration information of a network and the like, and establishing a boot image of a configurable network.
When the system fault damage needs to be recovered, under the condition of preparing the required hardware host, the host is booted and configured with a network by the boot mirror image, and then the backup software writes the information related to the backed up operating system: and partitioning the magnetic disk of the new host, simultaneously recovering all backed-up files, and automatically realizing the whole process by using backup software.
The following describes the disadvantages of the two existing backup protection methods for operating systems, which are as follows:
first, file-based backup recovery requires multiple reboots (operating system installation, patch installation, parameter modification production, application installation, etc.) during recovery, requires cooperation of multiple personnel and field attendance, has a complex operating process, and brings a large deviation to the overall system, such as the version of the system or program, the specific value of the parameter setting, etc.
Secondly, based on bare metal's backup recovery, for based on file's backup recovery, saved some steps and time, avoided the deviation that a large amount of manual operations brought, but the recovery based on bare metal is higher to backup operation maintenance requirement, generally need establish a guide mirror image to every different physical hardware and operating system, need utilize the guide mirror image of pertinence to accomplish the recovery when recovering, and the guide mirror image needs constantly to be updated moreover, otherwise can influence the speed of recovery and the state after recovering when the trouble appears.
In summary, in the two os recovery modes, it is still necessary to complete the os installation and complete the file recovery in the os in a manual or automatic mode, and it is still necessary to transmit recovery data, and the recovery time of the system is more time-consuming and depends on the link bandwidth of the data recovery transmission.

The quick recovery method for the operating system, provided by the embodiment of the invention, can be used for turning the operating system backup reserved in the emergency recovery platform into the emergency system after the operating system is backed up to the emergency recovery platform, directly mapping the emergency system to the host needing to be recovered as a system disk of the recovery host, supporting the recovery host to be directly started, avoiding the data transmission process, completing the recovery start of the system at the fastest speed and in the simplest steps, and solidifying the emergency system into a local disk of the recovery host by utilizing the reverse cloning of the disk after the recovery host is started.
In order to implement the method of the embodiment of the present invention, the storage space of the emergency recovery platform is pre-divided into two parts, namely an emergency boot area and a recovery reserved area, and the following description is provided for the emergency boot area and the recovery reserved area, specifically as follows:
the emergency starting area is used as an emergency system when the operating system fails, data recovery transmission is not needed, the host is directly started, and recovery preparation time is shortened;
and the recovery reserved area is used for reserving the historical copy of the operating system so as to select the required historical version to be turned over and then be started in an emergency under the fault condition.
All the operating system backups are written into the recovery reserved area, when the historical data needs to be recovered, the operating system backups are turned over from the recovery reserved area to the emergency starting area, and the operating system backups can be solidified from the emergency recovery platform to a local disk of the recovery host machine through reverse cloning after being started, so that subsequent starting is facilitated.
Referring to fig. 3, a fast reply scheme of an operating system according to an embodiment of the present invention is described in detail, and fig. 3 shows a schematic diagram of a recovery method 300 of an operating system according to another embodiment of the present invention, which is specifically as follows:
the first step, executing the backup of the complete system;
during backup, complete backup is performed on the relevant configuration information of the operating system, wherein the configuration information mainly includes boot information, disk partitions, content files and the like, so as to form a complete operating system backup, and each component of the configuration information is introduced as follows:
and (3) guiding information: for operating system hard disk boot up, transfers system control to the operating system specified and registered in the partition table (different operating systems have different boot information).
Network configuration: the configuration of the necessary network ports includes Media Access Control (MAC) addresses, IP information, and the like. So as to facilitate the network mapping start in the subsequent recovery and the connection verification after the recovery.
Partitioning a disk: the distribution of the partitions or the file systems on the operating system disk is responsible for explaining which partitions or file systems exist in the operating system, and the size and the use condition of each partition or file system.
Content file: what contents are contained in each partition or file system in the operating system and backed up.
The above 4 parts of contents form a complete operating system backup, the operating system backup is stored in a recovery reserved area of the emergency recovery platform for storage, and a general repeated data deletion technology and the like can be adopted in the storage process.
Referring to table 1, table 1 shows an exemplary table of operating system backup components:
TABLE 1
Secondly, selecting a backup to overturn when a fault occurs;
through the first step of the full operating system backup, the operating system such as boot information, network configuration, disk partitions, content files, and the like are recorded.
When the backup host fails, a historical copy of the operating system backup can be designated, and the operating system backup is turned into an emergency system.
During turning over, the partition size of the emergency system can be specified according to the partition size and the content size of the disk, and the network configuration of the emergency system can be modified during abnormal recovery.
It should be noted that in some embodiments, the backup host and the restore host may be the same host; in other embodiments, the backup host and the restore host may be heterogeneous.
As an example, referring to FIG. 4, FIG. 4 is a diagram illustrating an operating system backup roll-over according to an embodiment of the invention.
When a complete os backup is completed and stored in a recovery reserved area, an os backup needs to be turned into an emergency system and delivered to a recovery host for use, and how to turn over each component of the os backup is described as follows:
firstly, directly converting guide information, namely an original system is a Linux system, into guide information of an emergency system;
secondly, network configuration, wherein an IP address configured on a network card with an MAC address of 1A, 2B, 3C, 4E of the original system is 192.168.0.100, and a gateway is 192.168.0.1; in the embodiment shown in fig. 4, the roll-over is a modified roll-over for the reason of the abnormal recovery, the MAC address is modified to be 4e, 3c, 2b, ip address is 192.168.0.101, and the gateway is not changed. In other embodiments, the roll-over may be a same machine recovery.
It should be noted that fig. 4 is only one example. In other embodiments, one or more of the flipped MAC address, IP address, and gateway may be modified.
Thirdly, partitioning a disk, wherein 3 partitions are divided in the original system: partition 1 has a total space of 10GB, and 5GB is used; the total space of the partition 2 is 20GB, and 10GB is used; the total space of partition 3 is 30GB, and 15GB has been used.
In order to save the space of an emergency starting area, the disk subareas are corrected and turned, and the subarea 1 is divided into 8GB (more than 5GB (used), and <10GB (less than the total size)); partition 2 is divided into 18GB >10GB (greater than used), <20GB (less than total size) ]; partition 3 is divided into 28GB >15GB (greater than used), <30GB (less than total size).
It should be noted that the correction value for correcting the roll-over may be custom set as desired. In the above embodiment, in consideration of space utilization of the emergency starting area, the modification to the size of the partition cannot be smaller than the used partition and cannot be larger than the total size.
Finally, the content file, will be directly flipped over, and cannot be corrected.
Thirdly, directly starting emergency after mapping;
as an example, referring to fig. 5, fig. 5 shows an emergency system mapping diagram of an embodiment of the invention.
The overturning process is rapidly completed in the emergency recovery platform, and one or more emergency systems are formed after the overturning is completed and can be mapped to the recovery host machine for direct use.
The emergency system may be read-only mapped in a number of ways, including but not limited to FC (fiber Link) mapping or PXE boot (network Link), to map the emergency system to multiple recovery hosts through a switched network for an identified boot.
(1) Emergency system mapping
Different emergency systems are backed up and turned out by different operating systems, the emergency systems are mapped to the recovery host through a switching network in a read-only mode, and the emergency systems support the recovery host to be started through a system disk serving as the recovery host.
During which no recovery data need be transmitted.
The same emergency system can be mapped to a plurality of different recovery hosts in a read-only mapping mode, and the startup is executed at the same time.
The same recovery host may also accept mappings for different emergency systems, and upon startup one of the mapped emergency systems may be selected for startup.
(2) Emergency system start-up
Referring to fig. 6, fig. 6 shows a schematic diagram of the emergency system activation of an embodiment of the present invention.
As an example, the recovery host selects the available emergency systems that have been mapped (e.g., 1 from a plurality of emergency systems that have been mapped in different ways) at startup, and when the recovery host is started up by the emergency systems, a recovery log is created in the local disk space of the recovery host, where the recovery log is used to store newly written data, and the emergency systems are left unchanged as being in read-only mode, i.e., the host can be recovered immediately.
Fourthly, reverse cloning and curing of the emergency system;
after the recovery host completes emergency start through the emergency system, the emergency system can be solidified into a local disk of the recovery host through reverse cloning.
As shown in fig. 7, fig. 7 is a schematic diagram illustrating reverse clone curing of an emergency system to a local disk according to an embodiment of the present invention.
As an example, how the parts of the emergency system are reversely cloned when the emergency system is reversely cloned and solidified to the local disk is described as follows:
firstly, directly cloning the guide information into the guide information of a local disk of a recovery host;
secondly, the network configuration, because the mapping is completed, the MAC address of the recovery host is not modified, but the IP address can be modified again, the MAC address is 192.168.0.101 in the emergency system, and the gateway is 192.168.0.1; at the time of cloning, the IP address is corrected to 192.168.0.103, and the gateway is not changed.
It should be noted that fig. 6 is merely exemplary; in other embodiments, one or more of the MAC address, IP address, or gateway may be modified as desired.
And finally, partitioning a disk, wherein 3 partitions are divided in the emergency system: partition 1 is 8GB; partition 2 is 18GB; partition 3 is 28GB.
Referring to table 2, table 2 shows an exemplary table of the operating system backup of the restoration reserved area as shown in fig. 4, according to the backup information in the restoration reserved area in the second step:
when the emergency system clones the local disk, the emergency system can correct the local disk, and the partition 1 is divided into 15GB (greater than 5GB (used) and greater than 10GB (total size)); partition 2 is divided into 20GB >10GB (greater than used), =20GB (equal to total size); partition 3 is divided into 28GB >15GB (greater than used), <30GB (less than total size).
TABLE 2
Therefore, the correction value of the correction clone can be set by self according to requirements, and the network configuration and the disk partition can be adjusted according to specific requirements so as to deal with different recovery purposes.
And completing reverse cloning, namely after the emergency system is solidified to the local disk, restarting the recovery host computer at a proper time, disconnecting the mapping with the emergency system, selecting the local disk for guiding, and completing recovery.
According to the scheme provided by the embodiment of the invention, the operating system is completely backed up (for example, the operating system comprises guide information, network configuration, a disk partition, a content file and the like) during backup to form a complete operating system backup and store the complete operating system backup in the emergency recovery platform, when recovery is needed, the operating system backup is turned to a specific area (for example, an emergency starting area) of the emergency recovery platform according to requirements to form a complete emergency system, and then the emergency system is mapped to the host computer needing recovery, so that the host computer needing recovery can be directly started through the emergency system.
The scheme provided by the embodiment of the invention not only avoids a large number of redeployment steps, time and environmental deviation, but also does not need to maintain a large number of guide images, directly starts the host computer through the emergency system, does not need to carry out data transmission recovery, and greatly saves the time for recovering and using the system.
In summary, when the operating system fails, the operating system backup image of the dedicated emergency recovery platform is turned over to become the emergency system of the emergency boot area, and the emergency system is directly mapped to the recovery host, without transmitting recovery data, and the recovery host is directly booted through the emergency boot area.
In addition, the recovery reserved area is turned to the emergency starting area, the emergency starting area is started, and the emergency starting area can be reversely cloned to the local disk of the recovery host.
Therefore, the scheme provided by the invention not only can retain historical data copies of a plurality of operating systems to the great extent by means of backup recovery and by means of common backup technologies such as data de-duplication and the like; meanwhile, the rapid recovery of the operating system is realized by means of mapping after the emergency recovery platform is turned over at the highest speed and reverse cloning and curing; in the process of turning and cloning, different recovery requirements and environments are met under the condition that the operating system is ensured to be free of deviation, and the method is an operating system protection means with very balanced timeliness, performance and functions.
The technical effects of the scheme provided by the invention can be achieved as follows:
firstly, the traditional recovery data transmission process is not needed, the backup of the operating system is mapped after being turned over at the highest speed in the emergency recovery platform, the support recovery host is directly started, and the timeliness is very high.
Secondly, a plurality of time node historical copies can be reserved in the recovery reserved area by using a universal backup technology, and logic errors at each time point can be effectively repaired.
And thirdly, the emergency starting area supports various mapping links and mapping modes, correction parameters can be set in the turning and cloning processes, different environments can be effectively corresponded, and the large-batch quick recovery requirements can be met.
