[0043] The automatic drill method for block-level disaster recovery in this invention monitors the status of application ports in real time. When the application port is closed, a self-healing script is executed. When the application port is open, it determines whether the application server has persistent abnormalities. When self-healing fails or the application server has persistent abnormalities, a snapshot creation instruction is generated, and a derived snapshot creation instruction is used to automatically create virtual machines on the disaster recovery resource pool. The derived snapshot creation instruction automatically sets the resources of the virtual machines according to the original production environment and preset resource limitations. This solves the problem in existing technologies where ground-level disaster recovery cannot be automatically drilled in replication mode. Attached Figure Description

[0056] Figure 1 This is a flowchart of an embodiment of the automatic drill method for block-level disaster recovery of the present invention, as shown below. Figure 1 As shown, an automated drill method for block-level disaster recovery provided by an embodiment of the present invention includes the following steps:

[0057] S101, send the application server's backup folder to the disaster recovery computing resource pool;

[0058] Specifically, the control center 30 outputs a sharing command; after receiving the sharing command, the disaster recovery module 20 enables sharing permissions; and the backup folder of the application server 10 is shared to the disaster recovery computing resource pool 40 through the disaster recovery module 20.

[0059] S102, the disaster recovery computing resource pool creates virtual machines based on the backup folder;

[0060] Specifically, the control center 30 outputs a creation command; the disaster recovery computing resource pool 40 creates a test virtual machine based on the creation command and the backup folder. A virtual machine (VM) is a complete computer system simulated by software, possessing full hardware system functionality and running in a completely isolated environment. Any task that can be performed on a physical computer can also be performed in a virtual machine. When creating a virtual machine on a computer, a portion of the physical machine's hard drive and memory capacity needs to be used as the virtual machine's hard drive and memory capacity. Each virtual machine has its own independent CMOS, hard drive, and operating system, and can be operated just like a physical machine.

[0061] Virtual machine technology is a type of virtualization technology. Virtualization technology transforms things from one form to another. The most common virtualization techniques include memory virtualization in operating systems. In actual operation, the memory space required by users may far exceed the physical machine's memory size. Using memory virtualization technology, users can virtualize a portion of their hard drive as memory, and this is transparent to the user. Another example is Virtual Private Network (VPN) technology, which can be used to virtualize a secure and stable "tunnel" within a public network, making users feel as if they are using a private network.

[0062] S103, sets up the hardware resources of the virtual machine based on the original production environment;

[0063] Specifically, the hardware resources of the virtual machine are configured based on the original production environment and pre-set resource limitations;

[0064] The connection between the sandbox application module 60 and the application testing center 50 is set to be connected via a VLAN training network segment.

[0065] A network segment generally refers to the part of a computer network that can communicate directly using the same physical layer devices (transmission media, repeaters, hubs, etc.).

[0066] The Chinese name for VLAN (Virtual Local Area Network) is "virtual local area network".

[0067] A Virtual Local Area Network (VLAN) is a logical group of devices and users that are not limited by physical location. They can be organized based on factors such as function, department, and application, and their communication is as if they were on the same network segment, hence the name Virtual Local Area Network.

[0068] Communication between VLANs does not necessarily require a routing gateway. VLANs can form VLANs with different access control attributes by mutually allowing VLAN tags. This can also be achieved through a Layer 3 router. However, through the allowing of VLAN IDs and VLAN tags, VLANs can provide logical topology and access control for almost any information integration system architecture within a local area network (LAN), and achieve seamless sharing with other information systems sharing physical network links. VLANs can provide a virtual network topology architecture that conforms to the service structure and implements access control functions for information services and sub-services, as well as between information services. Compared with traditional LAN technologies, VLAN technology is more flexible and has the following advantages: reduced management overhead for moving, adding, and modifying network devices; control of broadcast activities; and improved network security.

[0069] S104, detect the working status of the application server's IP address and application port and obtain the detection results;

[0070] Specifically, the control center 30 outputs a detection command, which includes detection time information; the application detection center 50 detects the working status of the IP address and application port of the application server 10 based on the detection command; and sends the detection result to the control center 30.

[0071] S105 determines whether the IP address and application port are open based on the detection results. If so, it outputs control commands.

[0072] Specifically, when the IP address and the application port are closed, the control center 30 records the log and outputs a shutdown command; the disaster recovery module 20 receives the shutdown command and then shuts down the sharing mode; the virtual machine receives the shutdown command and then shuts down; the control center 30 records the ROT and RPO status.

[0073] S106, the sandbox application module implements automatic drills based on control commands.

[0074] Specifically, a sandbox, a computer science term, is a security mechanism in the field of computer security that provides an isolated environment for running programs. It is typically used to experiment with programs from untrusted sources, those that are destructive, or whose intent is unclear. A sandbox runs software in a restricted system environment, controlling the resources available to the program (such as file descriptors, memory, disk space, etc.).

[0075] The specific implementation of the sandbox:

[0076] Software jails: Restricted network access and limited file system namespaces. Software jails are most commonly used on virtual hosts.

[0077] Rule-based enforcement: Through system security mechanisms, it assigns certain access permissions to users and programs according to a series of preset rules, completely controlling program startup, code injection, and network access. It can also control program access to files and the registry. In such an environment, the chances of viruses and Trojans infecting the system are reduced. Security-enhanced Linux and AppArmor in Linux utilize this strategy.

[0078] Virtual machine: Simulates a complete host system, allowing a virtual operating system (guest system) to run as if it were running on real hardware. The guest system can only access the host's resources through the emulator, thus it can be considered a sandbox.

[0079] Local host sandboxing: Security researchers rely heavily on sandboxing techniques to analyze malware behavior. By creating an environment that simulates a real desktop, researchers can observe how malware infects a host. Several malware analysis services utilize sandboxing techniques.

[0080] Online judging system: used for program testing in programming competitions.

[0081] Secure Compute Mode (seccomp): A sandbox built into the Linux kernel. When enabled, seccomp only allows the write, read, exit, and sigreturn system calls.
