The invention is capable of other and different embodiments and its several details are capable of modification in various other respects, all without departing from the spirit and scope of the present invention.
Fig. 1 is a flowchart illustrating steps of a method for rapidly recovering a service system multiple times based on a system backup point according to the present invention. As shown in fig. 1, the method for rapidly recovering a service system for multiple times based on a system backup point of the present invention includes the following steps:
step S1, the hot backup source service server generates a consistent snapshot on the data storage server, and based on the consistent snapshot, the target service server quickly creates and pulls up a temporary virtual machine on the data storage server to verify the backup data and ensure the validity of the backup data.
Specifically, step S1 further includes:
step S100, the source service server obtains the consistency snapshot point through the snapshot technology, and the consistency snapshot point is backed up to the data storage server through the target service server. The consistent snapshot refers to consistency between data of a corresponding file system and metadata, the metadata is information used for describing data attributes and is used for supporting functions such as indicating storage positions, historical data, resource searching, file recording and the like, and when the data is written but the metadata is not recorded, or the data is not written but the metadata is recorded, the inconsistency is called, and the inconsistency may cause system startup failure.
In the invention, the source service server is the production service server, that is, the source service server creates a consistency snapshot point through a system online snapshot technology, acquires all configuration information and disk data of the source service server based on the consistency snapshot point, and transmits the configuration information and the disk data to the target service server, and the target service server backs up the data to the data storage server according to the acquired information. In the embodiment of the present invention, a backup proxy service program is installed on a source service server, and a backup service program is installed on a target service server (the backup service program is mainly used for receiving data sent by the backup proxy service program of the source service server and storing the data in a storage server), that is, the backup proxy service program of the source service server obtains a consistent snapshot point through a system online snapshot technology, and then backs up the snapshot point to the data storage server through the backup proxy service program of the target service server, it should be noted that a full backup point may be produced in the first backup, and an incremental backup point may be generated in the later backups.
Step S101, a virtual switch is created on the target service server to provide a network port and guarantee isolated network, and meanwhile, based on the backup data of step S100, a temporary virtual machine is quickly created and pulled up on the data storage server by the target service server to verify the backup data, so as to ensure the validity of the backup data. It should be noted that, for each backup point, it may select that each backup point is verified immediately after being completed, or may perform verification after a certain time period, or may even select a partial verification by using a sample check method, which is not limited in the present invention. In the embodiment of the present invention, the backup point is selected and then checked immediately.
Specifically, in step S101, validity verification needs to be performed on each backup point, and the specific process is as follows:
firstly, a virtual switch is created for an effectiveness verification task on a target service server through a software defined network technology, and an uplink port is kept vacant, namely the virtual switch is ensured to be isolated, so that the virtual switch is ensured to be separated from a production network logically, the network operated by the effectiveness verification task is ensured not to conflict with the production network, a physical network card is not required to be added, and the physical network configuration is not required to be changed. In the embodiment of the present invention, the virtual switch is created by a controller on the target service server (the controller is used for receiving user requests and calling different programs according to different requests), and a target service program of the target service server is called (it should be noted that, the controller in the present invention is deployed on the target service server, but the controller may be deployed on any node as long as the network communication can be achieved by the controller to create the virtual switch on the target service server), the controller can communicate with a standby service program of the target service server and can also manage the target service program of the target service server, the target service program is also called a virtual machine monitor, i.e. hypervisor, namely, the controlling machine calls a target service program (i.e., Hypervisor) API to create the virtual machine switch on the target service server.

Specifically, the floppy image file is temporarily generated on the target service server, and after the floppy image file is generated, the network configuration information on the snapshot backup point, that is, the configuration information of the source service server, is written into the floppy image file. The purpose of temporarily generating the floppy disk image file is to load a configuration file, so that the started virtual machine automatically configures the IP, and although the floppy disk image is not available, the virtual machine can also be started, but the IP does not exist.
The method comprises the steps of selecting a snapshot backup point on a data storage server by utilizing a virtualization technology, quickly creating a temporary virtual machine, and starting the temporary virtual machine, namely, calling a target service program by a control machine to quickly create the temporary virtual machine, wherein the quickness refers to that no large data are copied in the process, and the consumed time is short. The temporary virtual machine is generated by the backup of the source service server, the source service server is provided with a backup proxy service program, so the temporary virtual machine is also provided with the backup proxy service program, the backup proxy service program in the temporary virtual machine can detect a floppy disk in the starting process and configure virtual machine network information according to a floppy disk image file, and the purpose of virtual machine network automatic configuration is achieved.
Then, the user can log in the virtual machine through the vnc, judge whether the pulled temporary virtual machine is correct, and confirm whether the validity verification of the snapshot backup point is successful or failed by checking the service state or the file content and the like.
In the embodiment of the present invention, the verification method for verifying the validity of the backup point includes the following 3 types:
one, Ping virtual machine ip
Second, telnet virtual machine ip: port
And thirdly, executing a specific script, wherein success and failure are determined by the script.

Specifically, when the source service server fails, a virtual machine switch is created on the target service server through the software defined network technology (providing network ports and ensuring isolation), simultaneously, the uplink port of the virtual machine exchanger is connected with the production network card of the target service server, the network configuration information of the source service server is written into the temporarily generated floppy disk image file, then the control machine calls the target service program to select the snapshot backup point on the data storage server whose validity is successfully verified recently by using the virtualization technology to quickly create the virtual machine, setting the network card of the virtual machine as the virtual exchanger port, pulling up the virtual machine, detecting the floppy disk during the starting process of the backup proxy service program, and configuring virtual machine network information according to the floppy disk mirror image, automatically connecting the pulled virtual machine to the source service, and simultaneously writing data generated after the virtual machine is pulled into the data storage server.
And step S3, when the failure of the source service server is solved, restoring the data of the consistent backup snapshot backup point on the data storage server during takeover to the source service server, synchronizing new data generated during takeover of the virtual machine after the restoration is completed, and switching back to the source service server after the new data is successfully recovered. That is, after the failure of the source service server is resolved, the data transmission can be realized and the recovery operation can be completed by the communication between the backup agent in the source service server and the standby service program in the target server initiated by the user, that is, when the source service server runs, the virtual machine is closed, but the standby service program in the target server can access the disk data of the virtual machine, so that the data transmission is realized by the communication between the backup agent in the source service server and the standby service program in the target server, and the data can be switched back to the source service server after all the data are successfully recovered.
After the recovered source service server operates stably for a period of time, when the user determines that the system is reliable, the user may select to delete the virtual machine, which is not limited by the present invention.
Preferably, at ordinary times, the invention can also establish a virtual machine exchanger for testing purpose in the target service server by software defined network technology, and similarly, the control machine calls the target service program to select a snapshot backup point with successful validity verification by using virtualization technology, and quickly establishes one or more virtual machines for testing, and sets the network card of the virtual machine as the port of the virtual exchanger to pull up the virtual machine.
