Description

Technical Field

[0001] The present invention relates to the technical field of data storage, and in particular to a method and system for backing up virtual machine data, an electronic device, and a storage medium. Background Art

[0002] Backup data plays a crucial role in modern data storage and management systems. To ensure business continuity and data security, enterprises typically store a primary copy of critical data in a primary virtual machine (VM). They also create backup copies of this data and store them in separate VMs. This separate storage strategy aims to prevent single points of failure. If the primary VM or its data center fails, data and services can be quickly restored by rapidly launching the backup VM, effectively responding to catastrophic events.

[0003] However, managing backup data is not without its challenges. To ensure the validity and availability of backup data, regular health checks must be performed on backup VMs. These checks include, but are not limited to, verifying the integrity of the backup data, confirming the operating status of the VM's operating system, and detecting any issues that could affect VM startup or data recovery. This process is crucial for ensuring a seamless failover to the backup environment when needed and is a core step in implementing a disaster recovery plan.

[0004] With the increasing popularity of cloud computing and virtualization technologies, energy efficiency has become a key indicator of data center operational effectiveness. In practice, keeping backup virtual machines active at all times facilitates immediate inspection and failover, but significantly increases energy consumption. Active virtual machines consume significant power, generate excess heat, and require additional computing resources, increasing operational costs and potentially negatively impacting the data center environment.

[0046] The technical solution of the present invention is further described in detail below through the accompanying drawings and embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] The accompanying drawings are used to provide a further understanding of the present invention and constitute a part of the specification. Together with the embodiments of the present invention, they are used to explain the present invention and do not constitute a limitation of the present invention. In the accompanying drawings:

[0049] Figure 2 The present invention provides a block diagram of a virtual machine data backup system. DETAILED DESCRIPTION

[0050] The present invention will be further described in detail below with reference to specific examples, but the embodiments of the present invention are not limited thereto.

[0051] like Figure 1 As shown, a first aspect of an embodiment of the present invention provides a method for backing up virtual machine data, comprising the following steps:

[0052] Step 11: The backup virtual machine receives a startup instruction.

[0053] Step 12: The backup virtual machine reads the default configuration file of the boot program.

[0054] The default configuration file includes single-user mode parameters.

[0055] Step 13: The backup virtual machine starts up according to the default configuration file and enters single-user mode.

[0056] Step 14: The backup virtual machine reads the target service execution file from the startup directory in the single-user mode and runs the target service execution file.

[0057] Step 15: The target service execution file reads the network information file in the target setting directory and sets the network information according to the network information file.

[0058] In this embodiment, when the backup virtual machine is first started, the default configuration file in the boot program enters single-user mode by default. There are fewer programs running in single-user mode, which can reduce the energy consumption of the backup virtual machine and occupy fewer computing resources. At the same time, after entering single-user mode, only the target service execution file is run, that is, the backup virtual machine only starts the service in the target service execution file, and other services are not started. The target service execution file is used to set network information, so that when the backup virtual machine is first started, only the network information needs to be set, and no other services need to be started. The backup virtual machine completes the setting of network information, so that when the backup virtual machine is not needed, the main server can be used to detect whether the network connection status of the backup virtual machine is normal. The backup virtual machine does not need to run other functions, which significantly reduces energy consumption, saves a lot of electricity resources, and avoids occupying additional computing resources. This not only reduces operating costs, but also avoids adverse effects on the data center environment.

[0059] A second aspect of an embodiment of the present invention provides a method for backing up virtual machine data, which is applied to a Linux system and includes the following steps:

[0060] Step 21 : The local server deletes the original service execution file in response to the instruction to delete the original service execution file in the startup directory of the single-user mode of the backup virtual machine.

[0061] In this step, before deleting the original service execution file, a target service execution file is created in advance. Before the backup virtual machine is started, the original service execution file used to start the service in the startup directory in single-user mode is deleted.

[0062] In step 22, the local server stores the target service execution file, target setting directory and network information file in response to the instruction to add the target service execution file in the startup directory of the single-user mode of the backup virtual machine and the instruction to add the target setting directory and network information file in the single-user mode.

[0063] After deleting the original service execution file, the target service execution file is stored in the startup directory. This way, when the backup VM boots up, only the service corresponding to the target service execution file will run, and no other services will run. Simultaneously, a new directory is added to single-user mode, becoming the target settings directory. A pre-created network information file is then stored in the target settings directory. This network information file contains the backup VM's network information, including its MAC address, IP address, subnet mask, and gateway.

[0064] Step 23: The local server modifies the default configuration file in response to the instruction to add the single-user mode parameter to the default configuration file of the boot program of the backup virtual machine.

[0065] Before starting the backup VM, modify the default configuration file of the boot program and add the single-user mode parameter single to the default configuration file.

[0066] Taking the Linux system as an example, modify the grub.cfg boot menu and add the single parameter. This parameter means that the computer will start in single-user mode. The code example with the single parameter added is as follows:

[0067] [root@localhost grub2]# pwd

[0068] / boot / grub2

[0069] [root@localhost grub2]# vim grub.cfg

[0070] menuentry 'centOS Linux(3.10.0-693.el7.x86_64) 7 (core)' --classcentos --class gnu –class os –unrestricted $menuentry_id_option 'gnulinux-3.10.0-693.el7.x86_64-advanced-b01e725a-445f-467f-94a6-cbebfa5df3cc'{

[0071] load_video

[0072] set gfxpayload=keep

[0073] insmod gzio

[0074] insmod part_msdos

[0075] insmod xfs

[0076] set root='hd0,msdos1'

[0077] if [ x$feature_platform_search_hint = xy ]; then

[0078] search --no-floppy --fs-uuid –set=root --hint-bios=hd,msdos1 –hint-efi=hd0,msdos1 --hint-baremetal=ahci0,msdos1 --hint='hd0,msdos1' 01701220-010c-4f5c-8bf8-f6c2f16731d3

[0079] else

[0080] search --no-floppy --fs-uuid --set=root 01701220-010c-4f5c-8bf8-f6c2f16731d3

[0084] Here, the execution order of step 21, step 22 and step 23 is not particular, and the above steps are performed in the local server, that is, in the background end.

[0085] In step 24, the primary server sends a startup command to the backup virtual machine, which then receives the startup command. The primary server stores primary data, and the backup virtual machine backs up the primary server's primary data. The primary server can be a local server or a cloud server. The backup virtual machine can be local or cloud-based.

[0086] Step 25: The backup virtual machine reads the default configuration file of the boot program.

[0087] The default configuration file includes single-user mode parameters.

[0088] Step 26: The backup virtual machine runs the default configuration file to start up and enter single-user mode.

[0089] Step 27: The backup virtual machine reads the target service execution file from the startup directory in the single-user mode and runs the target service execution file.

[0090] After the backup virtual machine is powered on in single-user mode, it will automatically read the executable files in the startup directory / etc / rc.d / rc1.d. The startup directory only stores the target service execution file start.sh. The content of the target service execution file start.sh is the program for starting the required related services, that is, the program for setting network information.

[0091] For example, the code to read and run the target service execution file is as follows:

[0092] [root@localhost rcl.d]# pwd

[0093] / etc / rc.d / rc1.d

[0094] [root@localhost rc1.d]# cat start.sh

[0095] systemctl start dsgcdpagent

[0096] [root@localhost rc1.d]#

[0097] Step 28: The target service execution file reads the network information file in the target setting directory and sets the network information according to the network information file.

[0098] After the target service executable file runs, it reads the contents of the network information file in the target configuration directory and obtains and sets the network information. For example, after the target service executable file runs, it reads the contents of the takeoverip.conf file in the / home / dsgcdpagent / conf directory and sets the network information.

[0099] For example, the code to read the contents of the network information file in the target setting directory is as follows:

[0100] [root@localhost conf]# pwd

[0101] / home / dsgcdpagent / conf

[0102] [root@localhost conf]# cat takeoverip.conf

[0103] 00:0c:29:ba:f4:0a,192.168.80.207 / 24,192.168.80.1

[0104] [root@localhost conf]#

[0105] After the network information is set, the backup VM is started. Starting the backup VM only requires setting the network information; no other services need to be started.

[0106] Step 29: After the network information is set, the main server sends an ICMP echo request message to the IP address of the network information at a preset interval.

[0107] In step 30, the primary server detects whether it has received an ICMP echo reply message of the backup virtual machine corresponding to the IP address of the network information.

[0108] After setting up the network information, configure the same settings on the primary server to enable network communication with the backup VM. When the backup VM does not need to be backed up for disaster recovery, the primary server periodically pings the backup VM's IP address to check if the ping succeeds. If successful, the backup VM's network status is normal and the target service executable file is available. If unsuccessful, the backup VM's network status may be abnormal or the target service executable file may be abnormal.

[0109] In one feasible implementation, when disaster recovery is required, the backup virtual machine switches from single-user mode to multi-user mode to activate the corresponding services for disaster recovery. The primary server sends a disaster recovery command to the backup virtual machine. Upon receiving the command, the backup virtual machine switches from single-user mode to multi-user mode according to the command and then performs the disaster recovery operation.
