About conversion to virtual machines

Backup Exec provides the ability to convert to virtual machines in the following ways:

  • Back up a physical computer and simultaneously convert it to a virtual machine.

  • Back up a physical computer and schedule a conversion to a virtual machine to run after the backup job runs.

  • Convert existing backup sets to a virtual machine.

The newly created virtual machine is bootable and is identical to the physical computer from which the virtual machine was converted. Conversion to a virtual machine enables business continuity for both Hyper-V and VMware environments.

You use one of the following backup options on the Backup and Restore tab to set up a conversion to a virtual machine with a backup job:

Name of option

Description

Back up to Disk and Simultaneously Convert to Virtual Machine

Back up to Deduplication Disk Storage and Simultaneously Convert to Virtual Machine

These options run the conversion simultaneously with the backup job. Because two operations are performed at the same time, this job may take longer to run than a regular backup job. A large backup window is recommended for this option.

A conversion from a full backup creates the new virtual machine. Incremental and differential backups are not converted.

Although the backup runs simultaneously with the conversion, the backup is the primary job. Therefore, if the backup fails, then the conversion fails also. However, if the conversion fails, the backup continues to run. For a conversion failure, the job is marked as a success with exceptions. In the case of a failed conversion, the conversion process runs again during the next full backup.

These options let you schedule the conversion to run after the backup job. These options require a smaller backup window than the simultaneous conversion options.

A conversion from a full backup creates the new virtual machine. Incremental and differential backups are not converted.

Alternatively, you can add a stage to a backup job to convert to a virtual machine. Two types of stages are available: Convert to Virtual Machine After Backup and Convert to Virtual Machine Simultaneously with Backup.

The option Convert to Virtual From Point-in-Time is also available. A conversion to a virtual machine from a point in time converts existing backup sets from a backup job in which all components that are necessary for a virtual machine conversion were selected. When a backup job has all necessary components selected, Backup Exec identifies that job as Fully selected and the Simplified Disaster Recovery option has a status of ON The option to convert to a virtual machine from a point in time is useful in a disaster recovery situation in which you want to quickly recover a failed server. The backup sets contain all of the critical components of the server. Additionally, you can select application data or user data to include in the conversion.

Note:

The option Convert to virtual machine from point-in-time becomes available for selection only after you run at least one full backup that includes all critical system components.

Regardless of the option that is used to initiate the conversion, Backup Exec does not power on the virtual machine after creating it. You should not power on the virtual machine to validate that the conversion completed successfully.

Backup Exec creates a snapshot of the virtual machine at the end of the conversion process. The snapshot is removed before the next job runs as long as the virtual machine is not powered on and the only snapshot on the virtual machine is the one that Backup Exec created. If you want to start using the virtual machine, you must manually remove the snapshot.

If the converted virtual machine's host fails and you bring the virtual machine online, the existing conversion job continues to run and then fails. In this situation, you must create a new conversion job.
