Referring to fig. 2, fig. 2 is a schematic flowchart of a first embodiment of a testing method for virtual machine backup according to the present invention, where the method includes:
step S10, obtaining a source backup file of the virtual machine to be tested;
a virtual machine refers to a complete computer system with complete hardware system functionality, which is emulated by software, running in a completely isolated environment. Virtualization means that one physical computer is virtualized into a plurality of logical computers through virtualization technology, the logical computers are simultaneously operated on one computer, each logical computer can operate different operating systems, and application programs can operate in mutually independent spaces without mutual influence, so that the resource utilization rate of the computer is remarkably improved.
At present, an enterprise data center increasingly realizes "cloud" through a virtualization technology, a large number of virtual machines running in a virtualization platform are used for bearing a key service system of a client, and in order to guarantee data security and service continuity, the client generally backs up the virtual machines through the virtualization platform, but if backup recovery fails, the backup has no value on data protection. Therefore, the invention provides a method for carrying out backup recoverability test on a virtual machine.
The test method for the virtual machine backup can be realized through a virtualization platform. Firstly, a virtualization platform obtains a source backup file of a virtual machine to be tested, wherein the virtual machine to be tested can be specified by a tester according to business needs. In one embodiment, the tester may only specify a certain virtual machine for backup recoverability testing, and in further embodiments, due to the complexity of modern data centers, a large number of virtual machines are dependent on each other, such as for a simple three-tier web application: the front end is a web server, the middle layer is an application server, all of which are supported by some type of database server, and if the three functions are not available, the restoration condition of the application cannot be really tested, so that a tester can bind the three virtual machines to an application program group as a virtual machine to be tested and perform backup recoverability test on the virtual machine, and thus an enterprise can ensure and verify the backup recoverability of the whole application program instead of only a single virtual machine.
The source backup files of the virtual machine are generally mirror image files, the virtualization platform initializes the virtual storage first, and then obtains the source backup files of the virtual machine from the designated backup path.
Step S20, creating a virtual sandbox, creating and starting the virtual machine to be tested in the virtual sandbox according to the obtained source backup file;
in this step, the virtualization platform creates a virtual sandbox to provide an isolated operating environment for the backup recoverability test of the virtual machine.
After the source backup file of the virtual machine to be tested is acquired, an area for safely starting the virtual machines is needed, and the production environment is not affected. In this case, the virtual sandbox is effectively an isolated area isolated from the production network, but still maps the production network settings. By using isolated virtual sandbox techniques during backup recoverability verification, administrators and application owners can test the recoverability of backup files in this environment.
In the virtual sandbox, a virtualization platform creates a virtual machine according to an obtained virtual machine source backup file, specifically, a manager may configure test parameters for each virtual machine to be tested in advance, where the test parameters include, but are not limited to, an application group to which the virtual machine belongs, an application group role, a virtual machine operating system, memory and storage occupied by the virtual machine, start delay time of the virtual machine, and the like, and then the virtualization platform creates and starts the virtual machine to be tested according to the configured test parameters, including allocating memory and storage for the virtual machine according to the configured test parameters, controlling the virtual machine to start according to the set start delay time, and the like.
For example, the virtual machines 1, 2, and 3 to be tested may all belong to a web application group according to web service configuration, roles of the web application group are web, MySQL (relational database management system), and Apache (web server software), operating systems of the virtual machines 1, 2, and 3 are all Windows service 2008R2, start delay times of the virtual machines 1, 2, and 3 are 300ms, 100ms, and 200ms, respectively, and the subsequent virtual machines 1, 2, and 3 are started according to the configured start delay times. It should be noted that the purpose of configuring the delayed start time is to ensure the preconditions and the relevance of the virtual machine service, for example, it may be set that the database virtual machine is started first, the back-end virtual machine is started second, and the front-end virtual machine is started last, so as to provide a precondition guarantee for the simulation operation of the service.
And step S30, performing backup recoverability test on the virtual machine to be tested according to a preset test rule.
After the virtual machine to be tested is created and started, the virtualization platform performs a backup recoverability test on the virtual machine to be tested according to a preset test rule.
Specifically, the backup recoverability test may include: 1. signal detection: installing VMtools software (a virtual machine enhancement software) in a virtual machine operating system, then executing preset commands on the virtual machine, such as cursor control, data query, enabling/disabling an application program and the like, and if a signal returned by the VMtools software is matched with a preset signal, the test is passed; 2. ping test-the server sends a set of pings to the virtual machines through the spoofed IP address. If the virtual machine responds to these pings, the test passes; 3. application testing-depending on the type of virtual machine being tested, the virtualization management software may run a set of application specific automatic tests, for example, if the virtual machine is an AD controller (domain controller), the LDAP (Lightweight Directory Access Protocol) port may be set to 389, if the system responds, the test passes; 4. custom script-running a series of custom scripts against the target virtual machine, if the scripts run normally, the test passes.
The backup recoverability test method can be flexibly combined or used independently according to actual needs, and does not limit the backup recoverability test method of the virtual machine.
In addition, before each test, a snapshot file is generated according to the source backup file of the virtual machine so as to record the state of the virtual machine before the test, and the test rollback and the test check can be conveniently carried out subsequently.
In this embodiment, a source backup file of a virtual machine to be tested is obtained; creating a virtual sandbox, and creating and starting the virtual machine to be tested in the virtual sandbox according to the obtained source backup file; and carrying out backup recoverability test on the virtual machine to be tested according to a preset test rule. In the embodiment, the virtual machine is created in the virtual sandbox according to the source backup file of the virtual machine, and the backup recoverability test is performed on the created virtual machine, so that the availability of the backup of the virtual machine can be tested on the premise of not influencing production services, the technical problems that a virtualization platform cannot sense the availability of the backup and cannot perform drilling and testing on the recovery of the backup are solved, the recoverability of the backup once needed is ensured, and the safety of data and the continuity of services are guaranteed.
Further, referring to fig. 3, fig. 3 is a flowchart illustrating a testing method for virtual machine backup according to a second embodiment of the present invention. Based on the above embodiment shown in fig. 2, before step S10, the method may further include:
step S40, binding a plurality of virtual machines related to the preset service type to form an application program group;
and step S50, taking the virtual machine in the application program group as the virtual machine to be tested.
In this embodiment, the virtualization platform system may bundle a plurality of virtual machines related to a preset service type according to a setting instruction of a manager, so as to form an application group, where the application group represents the entire application program, and the application group includes a plurality of virtual machines, and the plurality of virtual machines have service relevance. For example, when the service type is an APP service, the front end, the back end, and the database virtual machine of the APP application may be bundled to form an APP application group; when the service type is web service, the virtual machines of the three-layer architecture (a website front-end server, a website background server, and a database server) of the web service can be bundled to form a web application group, and the like.
For each application program group, a name, a role, a description and virtual machines contained in the description can be set, and for each virtual machine in the application program group, various test parameters such as an operating system, the description, occupied memory and storage, a recovery time point, start delay time and the like can be set so as to ensure that the backup recoverability test of the virtual machine is carried out subsequently according to the set test parameters.
When the test is started, a tester selects one or more application program groups as application program groups to be tested, and uses the virtual machines in the selected application program groups as virtual machines to be tested. For example, there are currently two groups of applications A and B that are assigned to two different logical networks that are connected to a virtual switch within the production environment, and within a virtual sandbox where the IP and network information of the virtual machines are the same as the actual production environment, the virtual machines may run and communicate with each other, and the access of the virtual sandbox is restricted to the production network.
In this embodiment, an application program group is formed by binding a plurality of virtual machines related to a preset service type, and the virtual machines in the application program group are used as virtual machines to be tested, so that a relevance test can be performed on the virtual machines related to the application program, and the backup recoverability of a service system composed of the virtual machines is verified, that is, a service-level backup recoverability test is realized, and the security of service-level data and the continuity of services are guaranteed.
Further, referring to fig. 4, fig. 4 is a flowchart illustrating a testing method for virtual machine backup according to a third embodiment of the present invention. Based on the above-mentioned embodiment shown in fig. 2, after step S20, the method may further include:
step S60, judging whether the virtual machine to be tested is started normally within a preset time length;
if yes, executing step S30, and performing a recoverability test on the virtual machine to be tested according to a preset test rule;
if not, step S70 is executed to determine that the virtual machine backup to be tested is unavailable.
In this embodiment, when the virtual machine to be tested is started, the virtualization platform may determine whether the current start of the virtual machine to be tested is overtime, and if so, re-initiate the start command to start the virtual machine to be tested, and so on. If the virtual machine to be tested is detected to be normally started within the preset time length, performing recoverability test on the virtual machine to be tested according to a preset test rule, and if the virtual machine to be tested is not normally started within the preset time length, possibly causing data damage, virtual machine failure, bad magnetic disk track or hardware failure and the like, judging that the virtual machine to be tested is unavailable for backup at the moment, and generating a test report according to the unavailable backup result.
In the embodiment, the condition that the virtual machine to be tested cannot be normally started is considered, and when the virtual machine to be tested cannot be normally started, the virtual machine to be tested is judged to be unavailable for backup, so that testers can timely remove faults to perform subsequent backup recoverability test on the virtual machine.
Further, based on the first, second, and third embodiments of the testing method for virtual machine backup of the present invention, a fourth embodiment of the testing method for virtual machine backup of the present invention is proposed. In this embodiment, step S30 may include:
step S31, sending a preset network access instruction to the virtual machine to be tested through the virtualization platform;
step S32, if it is detected that the virtual machine to be tested normally responds to the network access instruction, determining that the virtual machine to be tested passes the backup recoverability test;
or, step S33, running a custom script on the virtual machine to be tested;
step S34, if the user-defined script is detected to run normally, the virtual machine to be tested is judged to pass the backup recoverability test.
In this embodiment, the method for performing a backup recoverability test on a virtual machine to be tested may be: sending a preset network access instruction to a virtual machine to be tested through a virtualization platform, if the virtual machine to be tested normally responds to the network access instruction, judging that the virtual machine to be tested passes a backup recoverability test, for example, a server sends a group of pings to the virtual machine through a disguised IP address, and if the virtual machine responds to the pings, the test is successful. The method for performing backup recoverability test on the virtual machine to be tested can also comprise the following steps: running a custom script on a virtual machine to be tested; if the self-defined script is detected to normally run, the virtual machine to be tested is judged to pass the backup recoverability test, for example, Select TOP (query operation) can be run for SQLserver (database software), or rest (representational state transfer) can be run for web server, and if the virtual machine normally responds to the operations, the test is successful.
Of course, for a certain virtual machine to be tested, the two methods can be simultaneously adopted to perform backup recoverability test, and flexible setting can be performed during specific implementation.
Further, based on the above embodiment, the method for testing virtual machine backup according to the present invention may further include: and generating a backup recoverability test report of the virtual machine to be tested according to the test result.
After the virtual machine to be tested is subjected to backup recoverability test, the virtualization platform generates a backup recoverability test report of the virtual machine to be tested according to a test result so as to clearly inform a client of feasibility of backup Recovery and a corresponding RTO/RPO index, wherein RTO (Recovery Time Objective) is the maximum Time length of service interruption tolerable for an enterprise; the RPO (Recovery Point object) refers to a time Point corresponding to data recovered after the service is recovered.
According to the recoverability test report, the customer can accurately know the backup security of the service system, and when the service system backup is unavailable, the customer can timely take corresponding measures (such as re-backup, data repair, hardware repair and the like) to remedy the backup data, so that the data security and the service continuity are guaranteed.

creating a virtual sandbox, and creating and starting the virtual machine to be tested in the virtual sandbox according to the obtained source backup file;
and carrying out backup recoverability test on the virtual machine to be tested according to a preset test rule.
Further, when executed by the processor, the test program backed up by the virtual machine further implements the following steps:
binding a plurality of virtual machines related to a preset service type to form an application program group;
and taking the virtual machine in the application program group as a virtual machine to be tested.
Further, when executed by the processor, the test program backed up by the virtual machine further implements the following steps:
judging whether the virtual machine to be tested is started normally within a preset time length or not;
