Example one

Fig. 1 is a flowchart of a data abnormal recovery method according to an embodiment of the present invention, where the embodiment is applicable to a situation that an abnormal recovery needs to be performed when a database fails, and the method may be executed by a data abnormal recovery device, where the data abnormal recovery device may be implemented in a form of hardware and/or software, and the data abnormal recovery device may be configured in an electronic device. As shown in fig. 1, the method includes:

s110, when a data recovery request is received, a virtual machine template is obtained according to the data recovery request, the virtual machine template is sent to a current client side, so that the current client side creates a data recovery environment based on the virtual machine template, and the data recovery request comprises a client side identification, a backup time period, an initial storage path, a current client side identification and a target storage path, wherein the client side identification is used for executing backup operation of backup data to be recovered.

The virtual machine template is a copy of a virtual machine with known parameter configuration, a deployed virtual machine is converted into the virtual machine template, and when the virtual machine is created through the virtual machine template, configuration parameters of the created virtual machine are the same as those of an original virtual machine of the virtual machine, that is, the virtual machine created based on the virtual machine template does not need parameter configuration.

In one embodiment, the virtual machine template is a MySQL database virtual machine template.

And the current client identifier is the identifier of the client sending the data recovery request. The initial storage path is a current storage path of the backup data to be restored, and the target storage path is a storage path of the backup data to be restored after restoration.

When a data recovery request is detected, corresponding configuration information is obtained according to the data recovery request, and a virtual machine template is obtained according to virtual machine version information in the configuration information. Specifically, the backup data to be restored and the attribute information of the backup data to be restored are determined according to the client identifier, the backup time period and the initial storage path, which execute the backup operation of the backup data to be restored, in the data restoration request, and the virtual machine template is obtained according to the virtual machine version information in the attribute information. For example, if the version information of the virtual machine is 5.7, a virtual machine template corresponding to the version of the virtual machine of 5.7 is obtained; and if the virtual machine version information is 8.0, acquiring a virtual machine template corresponding to the virtual machine version of 8.0. It can be understood that, the accuracy of acquiring the virtual machine template and the accuracy of creating data recovery can be improved by acquiring the virtual machine template according to the version information of the virtual machine, so that the accuracy of data recovery is improved.

And after the virtual machine template is obtained, sending the virtual machine template to the current client side so that the current client side completes the creation of a data recovery environment according to the virtual machine template. Specifically, the backup server additionally sends a virtual machine installation script while sending the virtual machine template to the current client, and after the current client receives the virtual machine template and the virtual machine installation script, the current client can run the virtual machine installation script to complete the operation of creating the data recovery environment based on the virtual machine, so that the speed and the accuracy of creating the data recovery environment are improved.

In one embodiment, when a data recovery request is detected, the configuration information of backup data to be recovered is acquired by the following steps: when a data recovery request is detected, account information of a current login user identifier is acquired; and when determining that the current login user identification has the data recovery right at the current moment according to the account information, acquiring corresponding configuration information according to the data recovery request.

Specifically, the account information includes a user identification, an authorization time period, and a bound IP address. When a data recovery request is detected, account information for sending the data recovery request is obtained, if the IP address used by the current login user identification is the same as the binding IP address, and the current time is within the authorized time period, the current login user identification is judged to have the data recovery authority at the current time, and meanwhile, the configuration information of the backup data to be recovered is obtained according to the data recovery request. The method and the device are used for reducing the access pressure and the data recovery pressure of the backup server and improving the data recovery speed of the backup server by limiting the login time of each account. The user identity and the data recovery authority are verified firstly, the configuration information of the data to be recovered is acquired after the data to be verified is passed, data leakage can be effectively prevented, and the safety of data recovery is improved.

The user identification information may be represented by a user token or a user name. The IP in this embodiment may be selected as a virtual private network address. It will be appreciated that the backup server may also verify the login account of the current client via the IP address.

In the fields of banks and the like, the requirements on the security, stability and reliability of data are very high, a core server or a database system for processing core data and services is generally deployed in a subnet which cannot be accessed by a public network, a web server for accessing the public network is deployed in the environment of another subnet, and the subnet is connected with the public network. In a Virtual Private Cloud (VPC) network, a user can realize access control over core data and a service server through access control between subnets, and the access requirement of a public network is met while the security and controllability of the core data are ensured.

The VPC operates on a public cloud, isolates a part of public cloud resources for a user and gives the right of the resources privately used by the user, the VPC ensures that the resources between each user are isolated, so that the flexibility of an IP address is very high, the problem of overlapping of the IP addresses is avoided, and the user is not influenced by other users when in use.

Regarding the authorization period, in one embodiment, the authorization period may be an hour of the day, or 2 hours, or 24 hours. For accounts with an authorization period of 24 hours, the time to access the backup server and data recovery is not limited. And when determining that the authorization time period corresponding to the account identification which sends the data recovery request is 24 hours, the backup server directly acquires the configuration information of the data to be backed up.

If the IP address used by the current login user identification is the same as the binding IP address and the current time is within the authorized time period of the binding IP address, judging that the current login user identification has the data recovery authority at the current time, and calling a management platform interface to acquire the configuration information of the backup data to be recovered according to the data recovery request. The configuration information of the backup data to be restored further comprises data packet version information, the size of the database space and the backup IP address.

Illustratively, the IP address bound by the currently logged-in user a is IP1, and the time period for which the data is authorized to be recovered is 9:00-17:00. firstly, determining whether an IP logged in by a user is IP1, if so, passing the authentication of the currently logged user A, then judging whether the current moment is within an authorization time period of the IP1, and if so, determining that the currently logged user A has data recovery authority; otherwise, the current login user A does not have the data recovery authority, and prompt information for indicating no data recovery authority is output.

Regarding the creation of the data recovery environment, in one embodiment, after acquiring the version information of the virtual machine, the database space and the backup IP address, a New-VM-VHDPath D: \ \ Disk1. Vhdx-memorystartbytes 4GB-Name VM1-SwitchName v switch-CPU 4-Disk 100GB-IPAddress 192.168.0.1 command is used to create a virtual machine VM1 with Disk1 as a template, the virtual machine includes a 4-core CPU and a 4GB memory, the virtual machine is connected to a vSwitch network, the IP address is 192.168.0.1, and the hard Disk capacity is 100GB.

And S120, when the data recovery environment of the current client is detected to be completely established, executing data recovery operation on the backup data to be recovered stored in the initial storage position to obtain recovered data, and storing the recovered data to a target storage position of the current client, wherein the current client and the client executing the backup operation on the backup data to be recovered can both access the initial storage position.

Based on an API (application programming interface) of the NetBackup Console, determining an initial storage position of the backup data to be restored in the backup server according to the client identifier for executing the backup operation of the backup data to be restored and the backup time, then performing data restoration on the backup data to be restored stored in the initial storage position to obtain restored data, and storing the restored data to a target storage position of the current client.

By restoring the backup data to be restored to the target storage position of the current client instead of restoring to the non-current client which executes the backup operation of the backup data to be restored, the situation that the non-current client is covered by data due to restoration of data storage and the situation that the data is lost due to data covering can be prevented, and therefore the safety of data restoration is improved.

In one embodiment, the backup server detects the data recovery process in real time, automatically verifies the integrity of the recovery data stored by the current client after detecting that the storage of the recovery data is completed, and improves the automation and timeliness of the verification of the integrity of the recovery data.

In one embodiment, after the data recovery is completed, the user can send a data integrity verification instruction to the backup server through the current client; and when detecting the data integrity verification instruction, the backup server verifies the integrity of the recovered data to generate an integrity verification result. In one embodiment, when the integrity verification passes, the integrity verification result is verification passing; when the integrity verification fails, the integrity verification result is verification failure, and when the integrity verification result is verification failure, the prompt information of the verification failure is output, and meanwhile, the reason of the verification failure is also output, such as data integrity error caused by data backup, data integrity error caused by a recovery process, or data integrity error caused by data storage. The data integrity verification can verify the accuracy of the recovered data, improve the user's knowledge of the data recovery process, and timely locate the root of the problem when the recovered data has a problem.

In one embodiment, a sandbox environment for the private network is built across network segments based on the VPCs, and the backup server verifies the integrity of the recovery data based on the sandbox environment. The integrity of a typical database file includes: entity integrity, which refers to the integrity of rows in a table, is mainly used to ensure that data (records) of operations are not empty, unique and not repeated; domain integrity, which refers to the integrity of the columns in a table, must satisfy some particular data type or constraint; and the integrity reference refers to an inter-table rule which is used for ensuring the consistency of data of the two tables. The present embodiment does not limit the way of verifying the integrity of the recovered data. A sandbox mode is built based on VPC and used for application verification after abnormal machine recovery, the requirement of a user on integrity verification of data recovered by abnormal machines of the MySQL database is met to a great extent, and safety of data recovered by abnormal machines of the MySQL database is improved.

In one embodiment, when a data recovery operation is detected, the different-machine recovery information is synchronized, and the different-machine recovery information comprises a backup server identification, a current client identification, virtual machine version information, data recovery time, a space capacity corresponding to recovery data, and an integrity verification result. The different machine recovery information is synchronized to the management platform, so that batch downloading, addition, deletion and query of MySQL different machine recovery information can be carried out by calling the management platform API, and the consulting and traceability of data recovery are improved.

Optionally, after the integrity verification of the recovery data passes, the backup server may automatically start the data recovery method provided in the embodiment of the present invention, build a data recovery environment on the current client through the virtual machine template, perform a data recovery operation on the backup data to be recovered stored in the initial storage location to obtain the recovery data, and store the recovery data to the target storage location of the current client. Compared with the prior art that the backup data to be restored is restored to the virtual machine which completes the backup operation, the backup data to be restored is restored to the current client, so that the data coverage condition caused by the restoration of the backup data to be restored can be avoided, and the safety of the data restoration operation is improved; the method and the device are not limited to restoring the backup data to be restored to the virtual machine which completes the backup operation, and can also improve the flexibility of data restoration.
