Step 4. Specify Recovery Verification Options and Tests
You must specify verification options for every VM in the application group:
- Select a role that a VM performs
- Configure startup settings
- Select tests that must be performed for the VM
- Specify credentials for running the verification script
To specify recovery verification options and tests for a VM:
- At the Virtual Machines step of the wizard, select a VM in the list.
- Click Edit on the right.
- Use the Verification Options window to specify the VM role, startup and test settings for the verified VM.
On the Role tab, select the role that the VM performs. Veeam Backup & Replication offers the following predefined roles for VMs:
- DNS Server
- Domain Controller (Authoritative Restore). In the Authoritative Restore mode, Veeam Backup & Replication starts a domain controller in the virtual lab and marks it as being authoritative to its replication partners. When other domain controllers (replication partners) are started in the virtual lab, they replicate data from the domain controller started in the Authoritative Restore mode.
- Domain Controller (Non-Authoritative Restore). In the Non-Authoritative Restore mode, Veeam Backup & Replication restores a domain controller in the virtual lab and marks it as being non-authoritative to its replication partners. Non-authoritative domain controllers then replicate data from a domain controller started in the Authoritative Restore mode.
- Global Catalog
- Mail Server
- SQL Server
- Veeam Backup for Microsoft 365 (machine on which Veeam Backup for Microsoft 365 is installed)
- Web Server
VM roles are described in XML files stored in the %ProgramFiles%\Veeam\Backup and Replication\Backup\SbRoles folder on the backup server. You can add your own roles. To do this, you need to create a new XML file and specify role and test scripts settings in it. For more information, see Creating XML files with VM Roles Description.
After you select a role for the VM, Veeam Backup & Replication will automatically configure startup options and assign predefined test scripts for the chosen role. You can use these settings or specify custom settings on the Startup Options and Test Scripts tabs.
To verify VMs that perform roles other than those specified in the list, you will have to manually configure startup options and specify test scripts that must be run for these VMs.
If you want to add several domain controllers to the application group, you must assign the Domain Controller (Authoritative Restore) role to the first domain controller started in the virtual lab. Other domain controllers must have the Domain Controller (Non-Authoritative Restore) role.
To specify VM startup settings:
- Click the Startup Options tab.
- In the Memory section, specify the amount of memory that you want to pre-allocate to the VM on the system boot. The amount of pre-allocated memory is defined in percent. The percentage rate is calculated based on the system memory level available for the production VM. For example, if 1024 MB of RAM is allocated to the VM in the production and you specify 80% as a memory rate, 820 Mb of RAM will be allocated to the verified VM on startup.
Veeam Backup & Replication does not allow you to change VM CPU manually, it does this automatically. If the VM has more CPU than the host can provide, Veeam Backup & Replication scales down the CPU of the VM.
- In the Startup time section, specify the allowed boot time for the VM and timeout to initialize applications on the VM.
Be careful when specifying the Maximum allowed boot time value. Typically, a VM started by a SureBackup job requires more time to boot than a VM started in the production environment. If an application is not initialized within the specified interval of time, the recovery verification process fails with the timeout error. If such error occurs, you need to increase the Maximum allowed boot time value and start the job again.
- In the Boot verification section, specify when the VM must be considered to have been booted successfully:
- VM heartbeat is present. If you select this option, Veeam Backup & Replication will perform a heartbeat test for the verified VM.
- VM responds to ping on any network interface. If you select this option, Veeam Backup & Replication will perform a ping test for the verified VM.
If you enable both options, Veeam Backup & Replication will require that both tests are completed successfully: heartbeat test and ping test.
To be able to perform the heartbeat test, Veeam Backup & Replication requires Hyper-V Integration Services to be installed in verified VM. If Hyper-V Integration Services are not installed, the VM will be started but the test will not be performed.
When you select a VM role, Veeam Backup & Replication automatically assigns a predefined script that must be run to verify applications inside the VM. If you want to verify a VM that has some other role not listed on the Role tab, do the following:
- Click the Test Scripts tab.
- Click Add.
- In the Test Scripts window, select Use the following test script.
- In the Name field, specify a name for the script.
- In the Path field, define a path to an executable script file that should be run to verify the VM.
- If you have your own custom script, define a path to it in the Path field.
- If you do not have a custom script, you can use a standard utility by Veeam, Veeam.Backup.ConnectionTester.exe, that probes application communication ports. The utility is located in the installation folder of Veeam Backup & Replication: %ProgramFiles%\Veeam\Backup and Replication\Backup\Veeam.Backup.ConnectionTester.exe. Specify this path in the Path field.
- In the Arguments field, specify an IP address of the verified VM and the port that you want to probe (if the selected test probes the port). You can use the %vm_ip% variable to define the VM IP address or the %vm_fqdn% variable to define the VM fully qualified domain name.
For Microsoft SQL Server, you can also specify a path to the log file in the %log_path% argument. For more information, see Backup Recovery Verification Tests.
- Click OK to add the configured test.
To edit test settings, select the test in the list and click Edit. To delete a test, select it in the list and click Remove.
If a VM performs several roles and runs a number of applications, you can verify their work by adding several verification scripts. It is recommended that you specify the maximum startup timeout value and allocate the greatest amount of memory for such VMs.
By default, to run the verification script Veeam Backup & Replication uses the account under which the Veeam Backup Service is running. If you need to run the script under some other account, you can specify credentials for this account in the application group settings.
- Click the Credentials tab.
- From the Credentials list, select credentials for the account under which you want to run the script.
If you have not set up credentials beforehand, click the Manage accounts link or click Add on the right to add the credentials. For more information, see Managing Credentials.
