For technical details that are not disclosed in the method embodiment of the present invention, those skilled in the art should refer to the description of the apparatus embodiment of the present invention to understand that, for the sake of brevity, detailed description is omitted here.
Based on the structure of the data backup device in the embodiment of the present application, a data backup method in the embodiment of the present application is further described in detail in combination with a specific application scenario shown in fig. 4; specifically, the method comprises the following steps:
step 1: a user manually initiates a backup request for data to be backed up in a backup client through a browsing component, such as a browser in the browsing component.
Here, in practical application, the browsing component is further provided with a web background service module, so that the browser communicates with the backup client through the web background service module and the communication gateway; moreover, the user can browse the resources needing to be backed up on the backup client by using the browser.
In practical application, the backup request can at least represent a backup task for performing backup processing on data to be backed up; further, the backup characteristic information of the backup task can be characterized, for example, the task identifier, the storage resource occupied by the data to be backed up, and other characteristic information.
Step 2: after the web background service module obtains the backup request initiated by the browser, the backup request is sent to the main control service module through the communication gateway.
And step 3: the main control service module starts a strategy scheduling process, the strategy scheduling process determines whether to run a backup task corresponding to the backup request based on backup characteristic information carried in the backup request, and if the backup task is determined to run, the strategy scheduling process sends the backup request to a task management module through a communication gateway; the backup request is sent to the task management module, for example, using a Remote Procedure Call (RPC).
In a specific scene, if the strategy scheduling process determines that the backup request is manually triggered by a user, directly operating a backup task corresponding to the spare part request; if the strategy scheduling process determines that the backup request is initiated by a strategy scheduling component (such as a strategy scheduler), whether the time for initiating the spare part request by the strategy scheduler meets the requirement is judged based on a preset rule, and if so, a backup task corresponding to the spare part request is directly operated; otherwise, the spare part request is ignored.
Here, in practical applications, the source of the backup request may be distinguished by the backup identifier in the backup feature information, that is, the identifier features of the backup identifiers in different initiating manners are different, so that the source of the backup request may be determined based on the backup identifier.
In a specific scenario, the data backup component is further provided with a detection module for detecting whether data stored in the backup client changes, and if the data stored in the backup client changes, the data to be backed up is determined based on the change characteristics of the data, and a backup request is generated and sent to the policy scheduler. For example, if it is detected that the data in the backup client is newly added, a backup request based on the newly added data is generated; or if the fact that the historical backed-up data is modified or increased in the backup client is detected, determining incremental data and/or differential data and further generating a backup request, so that incremental backup and differential backup are achieved, and backup requirements of different users are met.
And 4, step 4: the task management module starts a backup task thread based on the acquired backup request, and applies for the equipment required by the backup request to the media management service module through the backup task thread, for example, a first target media server meeting the backup request and equipment characteristic information of the first target media server are determined. After the device is applied, the media service component of the first target media server is notified, for example, the media service component of the first target media server is notified by the backup client by using the RPC, so as to run the backup task corresponding to the backup request.
Here, in practical applications, the first target media server may run on a Linux system, and at this time, the media service component is installed on the Linux system. The backup client can run on a Window system (namely, the data backup equipment runs on the Window system), so that cross-platform network spare parts can be realized; certainly, in practical applications, the first target media server and the backup client (or the data backup device) may also run on the same system, for example, both run on a Linux system, or a Window system, and the like, which is not limited in this embodiment of the present application.
And 5: and the media service component checks the equipment required by backup, then informs the backup client to run a backup task corresponding to the backup request through RPC, and waits for the backup client to create a data backup channel.
In practical application, the media service component specifically notifies the backup client to run the backup task by using the RPC and the server corresponding to the backup client, and waits for the backup client to create a data backup channel.
Here, the first target media server is used for managing the storage media collectively, and is also responsible for managing backup tasks/recovery tasks, data reading and writing of the storage media, and the like.
Step 6: and after receiving the notification of the media service component, the backup client starts a file backup subprocess and starts file backup, namely, the file backup subprocess establishes a data backup channel to the media service component by using a server corresponding to the client through TCP connection, namely, establishes a link between the backup client and the first target media server required by the backup determined in the step 4, then reads the data to be backed up for which the backup request is directed, and transmits the data to be backed up to the first target media server through the data backup channel.
In a specific application, the backup client is further provided with a task template, the backup client is further used for managing the task template, different backup requests can correspond to the same task template or different task templates, and the task template can be applied to any single backup client or applied to a backup client group in parallel.
Specifically, the task template may specifically include: characteristic information of the media server, equipment identification, backup strategy type, scheduling type, backup configuration option and the like; further, the backup client may also start different backup processes based on the policy type in the task template to complete the backup process, for example, if the policy type is a file resource, the backup client starts a file backup process to complete the backup process. In an application scenario, before a user initiates a backup request through a browser, a backup module corresponding to the backup request is selected from a backup client through the browser, and then a backup process of data to be backed up corresponding to the backup request is completed based on the backup module. That is, when a user initiates a backup request for data to be backed up in a backup client through a browser, the browser can be used to select a task template matched with the backup request (or select a task template matched with the data to be backed up), so that a templated backup process is completed by using the task template; or, the task template is not actively selected by the user, but the backup client confirms the task template based on the data characteristics (such as data type) of the data to be backed up, and carries the information (such as identification) of the task template in the backup request, so that the templated backup process is completed based on the characteristics of the task template, and the backup efficiency is improved.
In a preferred embodiment of the present invention, when a user selects a task template through a browser, the method specifically includes the following steps, so that the selection of the task template is more concise, efficient and user-friendly:
step 6-1, analyzing the backup request and the data to be backed up, and acquiring the template identifier of the backup request and the data characteristics of the data to be backed up;
step 6-2, if the template is identified as Null, one or more task templates corresponding to the data characteristics are displayed in a browser in a prominent mode; the highlighted mode display may be displayed in a different color from other task templates, or in the top of the ranking, for example.
6-3, if the template identification is not Null, judging whether the task template corresponding to the template identification exists in one or more task templates corresponding to the data characteristics, if so, directly taking the task template corresponding to the template identification as a selected task template, and not presenting a user in a browser for selection; and if not, displaying the task template corresponding to the template identification and one or more task templates corresponding to the data characteristics in a highlighted manner in the browser. Specifically, the task templates corresponding to the template identifications, the task templates corresponding to the data characteristics and other task templates are uniformly distributed in the same display mode.
And 7: and after receiving the data to be backed up through the data backup channel, the media service component writes the data to be backed up into the corresponding storage medium according to the user-defined format, thus completing the data backup process.
In practical applications, the storage medium may be embodied as a storage unit on the first target media server, or may also be an external storage medium controlled by the first target media server. Correspondingly, the device characteristic information of the first target media server in the step 4 at least comprises a server identifier and/or address information of a storage medium for storing data to be backed up, and the like, so that a foundation is laid for realizing data backup.
Here, in practical applications, the data backup component may further be provided with an index service module, configured to manage an index file for the backup task, so that the identifier of the backed-up data is conveniently and quickly retrieved, and the storage location of the backed-up data is further determined.
Based on the structure of the data backup device in the embodiment of the present application, the data backup method in the embodiment of the present application is further described in detail in combination with a specific application scenario; specifically, the method further includes a disaster recovery process, which specifically includes:
step 1: an external disaster-tolerant medium, such as an optical disc or a U disc, is manufactured, and the embodiment of the present application takes the optical disc as an example, which is hereinafter referred to as a startup optical disc; here, the startup disc is installed with the backup client.
In an actual scene, the optical disc is started, and a main program of the backup client can be installed, or a disaster recovery agent program is also installed. The main program of the backup client can realize the backup function of the backup client, or realize the functions of a data backup component and the backup client in the data backup device.
Step 2: after the starting of the optical disc is started by the Control component of the target device, the optical disc is accessed to the server corresponding to the backup client through a Transmission Control Protocol (TCP), so that the target device running the starting optical disc can realize the function of the data backup component by using the server.
Here, in a specific example, the target device may be specifically a data backup device; that is, when the data of the backup client in the data backup device is lost, the data recovery process can be completed by using the startup optical disc.
Here, in practical applications, the server corresponding to the backup client can have at least all functions of the data backup component.
And step 3: and determining a time point to be recovered on the main control interface of the target equipment by using the control component, generating a recovery request, notifying the recovery request to the web background service module, notifying the task management module to create a recovery task by the web background service module through the communication gateway, and acquiring recovery index information from the index service module and filling the recovery index information into the recovery task.
