A physical Linux file server needs to be migrated to VMware ESXi. The server has several volumes: /dev/sda (60GB), /dev/sdb (1TB) and /dev/sdc (4TB). What is the quickest option to migrate the server?

Instant VM Recovery is the fastest method for migrating a physical server to a virtual environment. This technology allows the server to be started as a virtual machine directly from the backup file stored in the Veeam repository. The VM is registered on the ESXi host and powered on in minutes, drastically minimizing downtime. The actual disk data is then migrated to the production datastore in the background using either VMware Storage vMotion or Veeam's Quick Migration technology while the server is already running and accessible.

A. Create an empty VM and perform bare metal recovery inside the VM.

This method requires a full restore of all data from the backup to the new VM's disks before it can be powered on, which is significantly slower than Instant Recovery.

C. Perform Instant Disk Recovery for each volume.

This feature is designed to restore individual disks, not an entire system. It would be a complex, multi-step process and not the quickest way to migrate a complete server.

D. Export all disks, create an empty VM and attach the disks.

Exporting disks from the backup file is a time-consuming process that must be completed before the VM can be created and started, making it slower than Instant Recovery.

Reference: "When you restore a Veeam Agent backup to a VMware vSphere VM

Veeam Backup & Replication uses the Instant Recovery technology. Veeam Backup & Replication publishes the content of the backup file as VMDK files on an ESXi host

creates a new VM with the required configuration and powers it on." This confirms that restoring a physical agent backup to vSphere uses the Instant Recovery mechanism

which is the fastest option.

Reference: "You can restore data from Veeam Agent backups to the original location or to a new location. For example

you can restore a backed-up physical machine to a VMware vSphere virtual machine." This section outlines the P2V (Physical-to-Virtual) capability.

"Instant VM Recovery"

"How Instant VM Recovery Works".

Reference: "During Instant VM Recovery

Veeam Backup & Replication uses the Veeam vPower technology to mount a backup file to an ESXi host and publish a VM from this backup. A published VM has a minimum downtime and users can access its disks as if they were regular VMDK files." This explains the underlying technology that makes option B the quickest.
