It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a flowchart of a data backup method according to an embodiment of the present invention, where this embodiment is applicable to a situation of backing up data, and the method may be executed by a data backup server, and specifically includes the following steps:
s110, a backup request of the data to be backed up is obtained, and the backup request carries target backup resources needed by the data to be backed up.
In this embodiment, the data to be backed up may be data distributed in MySQL databases in different areas, and the generated data needs to be backed up regularly to ensure the security of the data. For example, the generated data may be backed up periodically on a daily basis or on a weekly basis.
The MySQL database is a relational database management system that stores data in different tables.
In this embodiment, a Configuration Management Database (CMDB) is used to perform backup Management on data, where the CMDB is a logical Database and includes information of the full life cycle of Configuration items and relationships between the Configuration items.
As an optional implementation manner, the embodiment of the present invention supports an implementation manner of a Simple (Streaming) Text oriented Messaging Protocol (STOMP) subprotocol of the python language WebSocket, and can implement uniform scheduling, resource allocation, and backup result feedback of a backup task. Python is a cross-platform computer programming language, WebSocket is a network technology for full-duplex communication between a browser and a server, which is initially provided by HTML5, and the STOMP provides an interoperable connection format, which allows a STOMP client to interact with any STOMP message Broker (Broker).
Taking the daily set time for backing up the data as an example, when the preset backup time of the day is reached, the CMDB may obtain a backup request of the data to be backed up, where the backup request carries a target backup resource of the data to be backed up.
The target backup resource is the size of the backup resource needed by the data to be backed up, and if the target backup resource is 200G, it indicates that the current data to be backed up needs 200G backup resources.
And S120, distributing target backup equipment for the data to be backed up from the candidate backup equipment according to the target backup resources and the available backup resources of the candidate backup equipment, and using the target backup equipment to back up the data to be backed up.
In this embodiment, different Internet Data Centers (IDCs) are corresponding to each region where the MySQL database is distributed, each IDC corresponds to a resource pool for backup, each resource pool includes a plurality of hosts having available backup resources, and the hosts can be used for Data backup and program operation, and can be used as candidate backup devices for Data to be backed up.
The available backup resources of each candidate backup device are different, when the target backup device is selected, the backup device with the available backup resources larger than the target backup resources is selected from the candidate backup devices according to the target backup resources, and in order to further improve the resource utilization rate of the candidate backup data, the candidate backup device with the available backup resources slightly larger than the target backup resources can be selected as the target backup device.
Illustratively, if the target backup resource required by the current data to be backed up is 200G, five candidate backup hosts exist in the resource pool, wherein 2 available backup resources are greater than 200G, one candidate backup host is 300G, and the other candidate backup host is 250G, at this time, the candidate backup device with the available backup resource of 250G may be allocated to the data to be backed up as the target backup device to back up the data to be backed up, and the allocation manner of the target backup device improves the resource utilization rate of the candidate backup host.
According to the technical scheme provided by the embodiment of the invention, the backup request of the data to be backed up is obtained, the backup request carries the target backup resource required by the data to be backed up, and then the target backup equipment is allocated for the data to be backed up from the candidate backup equipment according to the target backup resource and the available backup resource of the candidate backup equipment, so that the target backup equipment is used for backing up the data to be backed up by using the target backup equipment.
Example two

S220, obtaining available backup resources of the candidate backup devices.
In this embodiment, the available backup resources of the candidate backup devices are different and may be dynamically changed according to the program running condition and the data backup condition of the candidate backup devices, so that the available backup resources of the candidate backup devices need to be acquired in real time to ensure the accuracy of the available backup resource information of the candidate backup devices.
And S230, taking the candidate backup device with the available backup resource larger than and closest to the target backup resource as the target backup device of the data to be backed up.
For example, if the target backup data of the data to be backed up is 300G, that is, the current data to be backed up needs 300G of backup resources, if there are 4 candidate backup devices in the current resource pool, which have available backup resources of 200G, 240G, 320G, and 400G, respectively, in order to achieve the maximum utilization rate of the resources of the candidate backup devices, the candidate backup device whose available remaining resources are 320G is selected as the target backup device of the data to be backed up.
The embodiment of the invention provides the technical scheme that the candidate backup equipment with the available backup resources larger than and closest to the target backup resources is used as the target backup equipment of the data to be backed up, so that the maximum utilization rate of the resources of the candidate backup equipment can be realized.
As another optional implementation, S120 further includes: obtaining available backup resources of each candidate backup device;
and if at least two candidate backup hosts with available backup resources larger than and closest to the target backup resources exist, taking the candidate backup host with the minimum load in the candidate backup hosts as the target backup host.
According to the embodiment, the candidate backup device with a small load is selected as the target backup data of the data to be backed up, so that the data backup speed and efficiency can be further improved.
As another optional implementation, S120 may further include: and acquiring available backup resources of the candidate backup devices, and taking the candidate backup device with the available backup resources larger than the target backup resources and the minimum load as a target backup host.
In this embodiment, if there are a plurality of candidate backup devices whose available backup resources are greater than the target backup resources, the candidate backup device with the smallest load is selected as the target backup host, so that the efficiency of data backup is appropriately improved under the condition of ensuring the resource utilization rate.
Furthermore, the available backup resources and loads of the candidate backup devices can be comprehensively considered, and the candidate backup devices with the available backup resources larger than the target backup resources and relatively smaller loads are selected as the target backup devices, so that the effective utilization of the resources and the efficiency of data backup are ensured.
