VMCE Flashcards – Chapter 7: Verification

[qdeck card_back=”none” random=”true”]

[i] Chapter 6: Verification

[q]In which versions of Veeam Backup & Replication can you make us of Automatic Recovery Verification, or Surebackup?
[a]Enterprise and Enterprise Plus.

[q]Can you manually verify VM backups with all versions of Veeam Backup & Replication?
[a]Yes you can, with the use of Instant VM Recovery.

[q]What is the general procedure of VM verification using Surebackup?
[a]1. Veeam Backup & Replication leverages the Instant VM Recovery technology to publish a VM in the isolated virtual environment. The VM is started directly from the compressed and deduplicated backup file residing on the backup repository.
2. Veeam Backup & Replication performs a number of tests against the verified VM.
3. When the recovery verification process is over, Veeam Backup & Replication unpublishes the VM and creates a report on its state. The report is sent to the backup administrator by email.

[q] Before you can automatically test a VM backup, you need to set up 3 parts within Veeam Backup & Replication. Which 3 parts do we need?
[a] 1. Application Group
2. Virtual Lab
3. Surebackup Job

[q] Which functionalities within Veeam Backup & Replication use the vPower technology?
[a]- SureBackup: Recovery Verification
– Instant VM Recovery
– Multi-OS File-Level Recovery
– Universal Application-Item Recovery (U-AIR)

[q] Why must the ESXi host, that you connect to with NFS, have a VMkernel interface?
[a] If you don’t have a VMkernel interface the vPower NFS mounting on the ESXi host will fail.

[q] To verify a VM started in the virtual lab, you can run Veeam’s predefined tests or perform your own tests against VMs. Which 3 tests do the predefined tests include?
[a] – Heartbeat test
– Ping test
– Application test

[q] What happens with the Surebackup test if you do not have Hyper-V Integration Tools or VMware Tools installed?
[a] Tests will be skipped; Veeam Backup & Replication will display a warning in the SureBackup job session results.

[q] Besides the recovery validation test in Surebackup, there is another test you can perform on a backup using a Surebackup Job. Which test is that?
[a] The Backup File Validation test – which is a CRC (Cyclic Redundancy Check).

[q] What happens if the validation tests are completed successfully but the backup validation (CRC) is not passed?
[a] Veeam Backup & Replication marks the SureBackup job session with the Warning status.

[q] Can you describe what an application group is?
[a] An application group creates the “surroundings” for the verified VM. The application group contains one or several VMs on which the verified VM is dependent. These VMs run applications and services that must be started to enable fully functional work of the verified VM.

[q] Which sources can you use to add a VM to an Application group and Surebackup Job?
[a] – VM backups
– VM replicas
– Storage snapshot

[q] Veeam Backup & Replication supports mixed application groups. You can add VMs from backups, storage snapshots and VM replicas to the same application groups. However, there are some restrictions when creating an application group. Can you sum up these restrictions?
[a] – VMs must belong to the same platform: VMware vSphere or Microsoft Hyper-V.
– VMs must have at least one valid restore point or must reside on a storage snapshot.
– You cannot add the same VM twice. For example, if you add a VM from the storage snapshot, you will not be able to add the same VM from the backup.

[q] The virtual lab is an isolated virtual environment in which Veeam Backup & Replication verifies VMs. It can also be used for 2 other Veeam features. Which features are that?
[a] – U-AIR
– On Demand Sandbox processing

[q] Which component enables communication between the production environment and the isolated networks in the virtual lab?
[a] the Proxy Appliance

[q] Typically, what is the IP adress of a Proxy appliance?
[a] Usually the IP address is the same as the IP address of the default gateway in the corresponding production network.

[q] For SureBackup recovery verification, Veeam Backup & Replication offers two types of the virtual lab configuration, which ones?
[a] – Basic single-host virtual lab
– Advanced single-host virtual lab

[q] For SureReplica recovery verification, Veeam Backup & Replication offers three types of the virtual lab configuration, which ones?
[a] – Basic single-host virtual lab
– Advanced single-host virtual lab
– Advanced multi-host virtual lab

[q] If you want to automatically verify VM replicas and VM replicas. The application group that you plan to start in the virtual lab must belong to the same Datacenter. Why is this?
[a] Distributed Virtual Switches can only belong to a single datacenter.

[q] The DVS port groups created on the DVS must be isolated from the production environment. To isolate port groups, which methods can you use?
[a] 1. Connect DVS uplinks to an isolated network. You can link the DVS you plan to use for recovery verification to an external, isolated network using uplink adapters. Note that these network configurations must be performed manually by the backup administrator.
2. Use VLAN tagging. This method can be used only if your router supports VLAN ID tagging. When specifying settings for isolated networks in Veeam Backup & Replication, you can define different VLAN IDs for different isolated networks. Setting VLAN IDs restricts communication of VM replicas in the isolated network with the production environment.

[q] What happens if you connect VMs from different production networks to one network in the isolated virtual lab?
[a] All VM replicas in the virtual lab will be started in the same network.

[q] What happens if Veeam Backup & Replication does not find a valid restore point for any of VMs from the application group?
[a] The SureBackup job will fail.

[q] Once the Surebackup verification process is complete, VMs from the application group are powered off. Optionally, you can leave the VMs from the application group running to perform manual testing or enable user-directed application item-level recovery. Where can you set this option?
[a] This should be set when you configure a SureBackup job.

[q] In order to perform tests for a verified VM without errors, Veeam Backup & Replication needs to know that the VM is ready for testing. Which stabilization algorithms are used?
[a] – Stabilization by IP
– Stabilization by heartbeat
– Stabilization by Maximum allowed boot time

[q] Which hypervisor(s) does Veeam support for SureReplica verification?
[a] Only VMware is supported. SureReplica is not available for Hyper-V.
