7. The rehearsal method based on virtual machine backup data as claimed in claim 5, characterized in that: in step S3, the management end is used to execute the added drilling script one by one, the IP of the drilling virtual machine in the drilling script uses the IP mapped by the production network segment, the mapped IP is forwarded to the proxy gateway eth0 entry, and is converted to the proxy gateway eth1 port for output through IP forwarding and NAT, and after the proxy gateway eth1 finds the target virtual machine in the isolated network, the response data is converted to the proxy gateway eth0 and finally returns to the management end.
8. The rehearsal method based on virtual machine backup data as claimed in claim 7, characterized in that: in step S3, the exercise task is executed periodically.
9. The drilling method based on virtual machine backup data as claimed in claim 8, wherein the periodic strategy execution drilling task comprises:
step S300, the drilling task is executed regularly according to the set drilling strategy, when the drilling task is executed regularly, the data of the last reducing point is searched each time, whether the drilling is executed in the previous time or not is judged, if the drilling is executed, the drilling is skipped, the drilling is re-checked and executed after the next period of scheduling is waited, and if the drilling is not executed, the step S301 is executed;
step S301, restoring the selected virtual machine or virtual machine set required to be used for drilling to the drilling platform, and configuring the network adapter of each drilling virtual machine as the isolated network
Step S302, the rule drilling script is executed by the management terminal.
10. A rehearsal system based on virtual machine backup data comprises the following components:
a virtual machine switch and proxy gateway creation unit, configured to create a virtual switch on the drilling platform according to the selected drilling platform to form an isolation network, and create a proxy gateway virtual machine on the drilling platform, configure two network adapters, one of which is configured to a source production network and the other is configured to the isolation network, and set an IP address and a network mapping relationship;
a virtual machine recovery unit, configured to add a drilling rule, create a virtual machine or a virtual machine group for drilling through the selected backup data, recover to the drilling platform, and configure a network adapter of each drilling virtual machine as an isolated network created by the virtual machine switch and the proxy gateway creation unit;
the task execution unit is used for completing a drilling task by executing the configured drilling script;
and the result recording unit is used for recording the results of successful execution and failure of the drilling script into drilling statistics and outputting a drilling report.
