All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
At present, the conventional disaster recovery exercise scheme can influence the normal operation of the business on the cloud host, and the disaster recovery exercise efficiency is lower due to the fact that manual operation is required. Therefore, the disaster recovery exercise scheme is provided, the disaster recovery exercise scheme which does not influence the host business is realized, and the disaster recovery exercise efficiency is improved.
Referring to fig. 1, an embodiment of the present application discloses a disaster recovery exercise method, including:
s101, acquiring a task of disaster recovery exercise of an operating original host.
In this embodiment, the task is created by a user management interface based on an SCP (Sangfor Cloud Platform, deep belief cloud computing platform), and the task includes a cloud host currently required to perform disaster recovery exercise, data required to be backed up by exercise, a backup position of the data, a backup mode, a data synchronization condition of the task, and the like. The SCP platform can be used for managing a plurality of HCIs (deep belief super fusion platform), and one HCI is used as a standby site for disaster recovery protection of the cloud host. Multiple hosts may be included in one HCI.
It should be noted that, the original host is provided with a corresponding HCI as its backup site, and in the normal operation process of the original host, the data generated and stored on the original host is synchronized to the HCI in a preset backup manner, so that when the original host fails, the original host is restored based on the HCI, and the continuity of service operation is ensured.
S102, determining the type of the task according to the data synchronization condition corresponding to the task.
The data synchronization conditions of the tasks can be instant synchronization and non-instant synchronization. The instant synchronization is as follows: the drill data and the data currently generated and stored by the original host are required to be synchronized as much as possible. Non-instant synchronization is: the exercise data is generated and stored by the original host at a certain time in the past, and the exercise data is not required to be synchronized with the data currently generated and stored by the original host.
Accordingly, the types of disaster recovery drilling tasks can be instant backup drilling and historical backup drilling. The instant backup exercise is as follows: the drill data and the data currently generated and stored by the original host are required to be synchronized as much as possible. History backup exercise is: the exercise data is generated and stored by the original host at a certain time in the past, and the exercise data is not required to be synchronized with the data currently generated and stored by the original host. The exercise data is the data which needs to be backed up from the original host and is used for disaster recovery exercise of the original host currently.
In a specific embodiment, determining the type of the task according to the data synchronization condition corresponding to the task includes: if the data synchronization condition is instant synchronization, determining that the type is instant backup exercise; otherwise, determining the type as the history backup drilling.
S103, determining exercise data corresponding to the task in the standby site of the original host according to the type.
In a specific embodiment, determining exercise data corresponding to a task in a standby site of an original host according to a type includes: if the type is the instant backup exercise, determining exercise data according to the data backup mode of the original host; if the type is history backup exercise, determining all backup data of an original host in the current backup site as exercise data, namely, executing the current disaster recovery exercise task without deliberately backing up the data, and directly using the data backed up before in the backup site.
In a specific embodiment, determining exercise data according to a data backup mode of an original host includes: if the data backup mode is CDP (Continuous Data Protection ) backup, when the RPO (Recovery Point Objective, recovery point target) state meets the preset condition, determining all backup data of the original host in the current backup site as exercise data; if the data backup mode is not CDP backup, the drilling data in the original host computer is backed up to the backup site. At this time, the exercise data and the data currently generated and stored by the original host are required to be synchronized as much as possible, and it is required to wait until the RPO state meets a preset condition (that is, the difference between the exercise data and the data currently generated and stored by the original host meets the preset condition), or directly perform data backup (although the data on the original host can be periodically synchronized to the backup site, in order to minimize the difference between the two data, improve the backup efficiency, reduce the backup data volume, and at this time, backup the difference data between the two data) so as to minimize the difference between the exercise data and the data currently generated and stored by the original host.
It should be noted that, to ensure smooth completion of the disaster recovery exercise task, the primary host that needs to perform the disaster recovery exercise may be locked, so as to avoid failure of the disaster recovery exercise caused by maintenance, update, and other operations performed on the primary host by other personnel. Therefore, in one embodiment, before backing up the exercise data in the original host to the backup site, the method further includes: judging whether the original host can start disaster recovery exercise; if yes, locking the original host machine into a disaster recovery drilling progress state, and executing the step of backing up drilling data in the original host machine to the standby site. Correspondingly, after the drilling host which is completely the same as the original host is created in the standby site based on the drilling data, the method further comprises the following steps: and unlocking the original host to be in a disaster recovery drilling completion state.
Wherein, judge whether former host computer can start disaster recovery exercise, include: judging whether the original host is in a disaster recovery exercise progress state and a host abnormal state or judging whether the original host is executing a task mutually exclusive with the disaster recovery exercise.
And S104, creating an exercise host which is completely the same as the original host in the standby site based on the exercise data, and starting the exercise host to check the availability of the exercise host.
It should be noted that, a task may perform disaster recovery exercise on multiple primary hosts at the same time. If there are multiple original hosts and the multiple original hosts belong to the same service group, after the exercise hosts which are completely the same as each original host are created, starting each exercise host one by one according to the starting priority of each original host in the service group to which each original host belongs, and recording the service group to which each exercise host belongs. For example: the number of the original hosts is 3, and all the original hosts belong to the service group A, so that 3 exercise hosts can be created, the 3 exercise hosts are started one by one according to the starting priority of the 3 original hosts, and the 3 exercise hosts are recorded to belong to the service group A.
If there are multiple original hosts and the multiple original hosts belong to different service groups, after the exercise host which is completely the same as each original host is created, starting each exercise host one by one according to the service priority of the service group and the starting priority of each original host in the service group to which each original host belongs, and recording the service group to which each exercise host belongs. For example: the original host has 3: the original host 1, the original host 2 and the original host 3, wherein the original host 1 and the original host 2 belong to a service group B, the original host 3 belongs to a service group C, after 3 exercise hosts (the exercise host 1, the exercise host and the exercise host 3) are created, which service group is started first is determined according to the service priorities of the service group B and the service group C, then each exercise host is started one by one in the service group according to the starting priorities of each original host in the service group, and the exercise host 1 and the exercise host 2 belong to the service group B and the exercise host 3 belongs to the service group C are recorded. Different drilling hosts can correspond to the same standby site or different standby sites.
In one specific embodiment, the method further comprises: and configuring the network where the standby site is located according to the original network of the original host computer so as to obtain the exercise network which is completely the same as the original network. The configuration of the network where the backup site is located is that: and generating a new route, a new switch and other network nodes with the same positions, functions and the like in the original network, and connecting the new route, the new switch, the standby site and the other network nodes to obtain the exercise network which is completely the same as the original network.
In one specific embodiment, the method further comprises: and deleting the exercise record corresponding to the task after the disaster recovery exercise is completed. The drill record includes: the exercise host, the exercise network, the grouping of exercise hosts, and other information generated when performing tasks.
Therefore, according to the embodiment of the application, disaster recovery exercise can be performed on the running original host, in the process of disaster recovery exercise, the task type is determined according to the data synchronization condition corresponding to the disaster recovery exercise task, so that exercise data required by the disaster recovery exercise are determined in the standby site according to the task type, and accordingly the exercise host which is completely the same as the original host is newly created, and the original host still operates at the moment, namely: instead of replacing the original host with a newly created exercise host, the newly created exercise host is allowed to coexist with the original host. Therefore, the disaster recovery exercise scheme provided by the application does not influence the normal operation of the business on the original host, and because the exercise data required by the disaster recovery exercise are executed based on the data synchronization condition corresponding to the disaster recovery exercise task, manual operation is not needed, so that the disaster recovery exercise efficiency can be improved.
The embodiment of the application discloses a scheme for performing disaster recovery exercise in batches. According to the scheme, disaster recovery exercise is carried out on the cloud hosts in the service groups, an exercise network isolated from a production network (an original network where an original host is located) is generated, and records generated by the exercise at the time can be cleaned by one key later, so that the disaster recovery exercise flow is simplified, and the efficiency is improved.
Referring to fig. 2, a disaster recovery exercise task is a recovery plan, where the recovery plan includes a plurality of service groups, and each service group includes a plurality of cloud hosts (i.e., original hosts) that need to perform disaster recovery exercises. The execution of the recovery plan needs to lock the service group (i.e., lock the cloud host performing disaster recovery exercise as the disaster recovery exercise progress state) so as to prevent other operations from affecting the disaster recovery exercise process. The service group execution stage needs to record grouping information of each service so as to group the exercise host after the exercise host is created and obtained. The cloud host execution stage needs to provide resources (exercise data, data backup locations, network resource configuration information, etc.) required for creating an exercise host, and record relevant information (affiliated backup sites, etc.) of the exercise host.
After each drilling host is created and pulled up, the drilling network is configured based on the standby site to which each drilling host belongs, and network resource information of the drilling network is recorded. The drilling network is not connected with any physical network card and is not connected with the production network, so that the production environment is not affected. After that, the user can manually check the availability of each exercise host, and after the checking is finished, the user can clean the exercise resources generated by the exercise at this time through the function of ending the exercise in the user management interface.
Referring to fig. 3, any cloud host in the present disaster recovery exercise task can perform disaster recovery exercise accordingly.
1. Locking a cloud host which needs disaster recovery exercise, and setting the state of the cloud host into exercise. And recording resource information (such as ID and name) required by the drill (i.e. drill host) and setting the record state as in the creation, and determining the task type according to the data synchronization condition of the task.
2. If the real-time synchronous data is not needed, the task type is no_sync; if the data needs to be synchronized immediately and the cloud host uses CDP to backup the data, the task type is wait_ CDP; if the data needs to be synchronized immediately, but the cloud host backs up the data in other ways, the task type is sync_backup.
3. If the task type is sync_backup, checking whether the cloud host can start disaster recovery drilling. If the cloud host state is abnormal or disaster recovery exercise is already performed, the exercise task fails. If the cloud host can start disaster recovery exercise, immediately backing up data required by the exercise to the standby site.
4. If the task type is wait_ cdp, the RPO state is detected at regular time until the RPO state is detected to meet the preset condition, and the data required by the exercise are considered to be ready in the standby site.
5. If the task type is no_sync, it is considered that data synchronized to the standby site in the past can be used as data required for the exercise. Data synchronized to the backup site in the past may also be obtained using CDP backup.
6. For the data required by the exercise, if the data is obtained by using the CDP backup, the cloud host is newly built and restored from the CDP backup (i.e. the exercise machine is created), and if the data is obtained by using the ordinary backup, the cloud host is newly built and restored from the ordinary backup (i.e. the exercise machine is created).
7. The configuration of the disaster recovery backup machine (i.e. the cloud host) is used to modify the configuration of the exercise machine (such as the configuration of the CPU, the memory, the network, etc.) so as to keep the exercise machine and the cloud host consistent.
8. Updating the record state of the drilling machine to finish the creation, starting the drilling machine, unlocking the disaster recovery state of the cloud host, and setting the state to finish the drilling.
When executing the startup task of the drilling machine, it is necessary to check whether the drilling machine with high priority is started or not, and after waiting for the drilling machine with high priority to start up, the drilling machine with low priority is started up. The priority is ordered according to two factors, the importance of the service group and the host initiation priority.
Referring to fig. 4, fig. 4 is a flowchart of generating an exercise network. The exercise network generation step comprises the following steps:
1. and obtaining topology information of the current network of the standby site, wherein the topology information is generated according to the existing configuration of the cloud host.
2. And traversing the network of the standby site by adopting a strategy of depth-first search to filter configuration information of network nodes, routes, switches and the like involved in the drilling, and copying a drilling network which is the same as the production network by means of the configuration information and the existing configuration of the cloud host.
3. Topology nodes required in the exercise network are generated, and network resources of the topology nodes are recorded, wherein the nodes comprise exercise machines, routers and switches.
4. The switches and routers that have been generated are validated.
5. Because the topology nodes are automatically generated, topology links between nodes need to be created after validation.
6. Setting IP information of the topological node.
Referring to fig. 5, the process of cleaning the exercise record includes:
1. and acquiring all uncleaned resource records (including exercise hosts, cloud host groups, network devices and the like) of the exercise from a resource record list generated during the exercise.
2. Cleaning the drilling cloud host:
if the cloud host still exists, the cloud host needs to be moved to the recycle bin first and then thoroughly deleted from the recycle bin. After deletion, the resource record is set as deleted.
If the cloud host is moved to the recycle bin, the corresponding drill is completely deleted from the recycle bin directly. After deletion, the resource record is set as deleted.
If the cloud host has been completely deleted, only the resource record needs to be set as deleted.
3. And cleaning the cloud host group and setting the corresponding resource record as deleted. If the packet has been deleted in advance, the deletion action is skipped.
4. And cleaning network equipment in the drilling network, and setting the corresponding resource record as deleted. If the network device has been deleted in advance, the deletion action is skipped.
Therefore, in the embodiment, the disaster recovery exercise is performed on the cloud hosts in the plurality of service groups, the exercise network isolated from the production network is generated, and the record generated by the present exercise can be cleaned by one key, so that the disaster recovery exercise flow is simplified, the efficiency is improved, and the disaster recovery exercise scheme which does not influence the user service and is easy and convenient to operate is realized.
