[i] Chapter 7: Entire VM Recovery
[start]

[q] Which Full VM Recovery method does use vPower NFS?
[a] Instant VM Recovery

[q] Instant VM recovery is an intermediate step in recovering a VM. When you finalize the restore and migrate the VM back to production, which methods can be used to migrate the data back to production storage in a VMware environment?
[a] – VMware storage vMotion
– VMware Cross-Host vMotion (XvMotion)
– Quick Migration
– Replication or VM Copy functionality and then Failover the VM

[q] Can you discribe how an Instant VM recovery is performed on the Hyper-V platform?
[a] – Veeam read the VM config file and crate a dummy VM with the same settings on the destination host
– Veeam creates a snapshot of the dummy VM to prevent data loss if the recoveru process should fail
– On the destination host the a Veeam proprietary driver which is able to redirect request to the file system of the recovered VM and reads data from the backup file
– To finalize veeam starts a 2nd pair of Data Movers to copy the data from the backup repository to the destination host.

[q] How does Veeam perform perform a Full VM restore?
[a] Veeam Backup & Replication pulls the VM data from the backup repository to the selected
storage, registers the VM on the chosen ESXi or Hyper-V host and, if necessary, powers it on.

[q] What are advantage of using Quick Rollback when performing a Full VM restore?
[a] – Significantly reduces the recovery time.
– Has little impact on the production environment.

[q] What are situation in which you should not use Quick Rollback when performing a Full VM restore?
[a] Do not use incremental restore if the problem has occurred at the VM hardware level, storage level or due to a power loss. Only use it when you restore a VM after a problem that has occurred at the level of the VM guest OS.

[q]What are the requirements for incremental restore?
[a] – VM is restored to its original location.
– The backup file from which you plan to restore a VM is created with the Changed block tracking option enabled

[q] Can Veeam backup made by the Veeam Agents for Windows/Linux be restored to Azure?
[a] Yes, but only if the backup if created af the volume level, not when made on the file level.

[q] What are limitations when using Veeam Restore to Azure?
[a] – The maximum size of one disk for a VM in Microsoft Azure is 1023 GB.
– If the system disk of an initial machine uses the GPT partitioning scheme, the number of partitions on the disk cannot exceed 4. During restore such disk will be converted to a disk with the MBR partitioning scheme.

[q] Which interfaces can you use to utilize the extract utility?
[a] – Graphic user interface (can be started on Microsoft Windows machines only)
– Command-line interface working in the interactive or regular mode

[q] The installation folder of Veeam Backup & Replication (by default: %PROGRAMFILES%\Veeam\Backup and Replication\Backup) contains three files for the extract utility; which 3 files?
[a] Veeam.Backup.Extractor.exe – The utility working via the graphic user interface(Microsoft Windows machines only)
extract.exe – The utility working via the command-line interface(version for Microsoft Windows)
extract – The utility working via the command-line interface(version for Linux)

[q] Which type(s) of backups can the extract utility restore?
[a] Only Full Backup files.

[q] Can you describe what a Permanent Failover is and in what scenario this would be the recommended action?
[a] A Permanent Failover is the switch from the original VM to a VM replica and use this replica as the original VM. This is best when the original VM and a VM replica are located in the same site, and hosts and storage are nearly equal in terms of resources. In this case, your users will not experience any latency in ongoing operations.

[q] Can you describe what a Failback is and in what scenario this would be the recommended action?
[a] This is best when the VM replica is located in a DR site and is running on a lower tier host and storage, which is not intended for continuous operations.

[q] Can you describe what an Undo Failover is and in what scenario this would be the recommended action?
[a] This is best when you want to perform some testing and troubleshooting of the VM replica without affecting the production environment in any way.

[q] Which 3 Failback options does Veeam Backup & Replication offers?
[a] – Failback to a VM in the original location on the source host
– Failback to a VM that has been restored up-front from a backup in a new location
– Failback to an entirely new location by transferring all replica files to the selected destination

[q] When could or would you use a Failover Plan?
[a] If you have a number of VMs running interdependent applications, you need to failover them one by one, as a group and you want to Automate these actions.

[q] What are the finalizing steps for a Failover?
[a] undoing failover, permanent failover or failback
