Backup Exec 2012 Conversion to a Virtual machine overview.

 


Solution



Terminology:
P2V: Virtual conversion from a running physical machine.
B2V: Virtual conversion from existing SSP\SDR backup sets
PIT: Point in time of the SSP\SDR backup sets that can be selected for the conversion process
SSP: Simplified system protection
SDR: Simplified disaster recovery


In Backup Exec 2012 you can back up a physical computer and convert it to a virtual machine either simultaneously with the backup job or after the backup job. You can also convert an existing backup set to a virtual machine. This feature enables business continuity for both Hyper-V and VMware environments.
The end result of the conversion process will be a virtual machine that can be powered on and used when the physical server goes down (business continuity).
The newly created virtual machine is bootable and is identical to the physical computer from which the virtual machine was converted.


Backup Exec provides the ability to convert to virtual machines in the following ways (Backups can be tape or disk storage):
■ Back up a physical computer and simultaneously convert it to a virtual machine (P2V).
■ 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 (B2V/PIT).


P2V/B2V methods:


P2V is always done parallel to backup. Conversion from a running system is always done in parallel with the SSP\SDR backups.
Conversion Virtual target can be virtual machine (Warm) or virtual disks (Cold). Warm standby results in a bootable virtual machine instance. Cold standby results in virtual disk(s).
The disks can be made bootable during the conversion process and the conversion process either P2V or B2V always keeps the same disk geometry as that of the source.
Supports FULL backup method.
FULL conversion results in a new VM or new Virtual disks.
B2V conversion is always done after the full backups and uses the existing SSP\SDR backup sets.
 

Workflow:

Backup is considered the primary task during P2V.
Backups will continue even if the conversion fails and backup the remaining data.
If the backup fails, the conversion will also fail.
After a failed conversion, the conversion process will not run until the next FULL backup is performed.

After the physical server has failed and the (business continuity) has switched over to the virtual machine created by the conversion process, the subsequent conversion jobs will detect this switch and keep failing the job.  A new backup has to be create to protect the failed over virtual machine.

 

Converting to a virtual machine from a point in time:

A conversion to a virtual machine from a point in time converts existing backup sets from a backup job in which the Simplified Disaster Recovery (SDR) option was
enabled. The Simplified Disaster Recovery (SDR) option enables all of the critical system components for a virtual machine conversion to be included in the backup job.


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 necessary components of the system. Additionally, you can select application data or user data to include in the
conversion.
