TopicPhysical to virtual Disaster Recovery (DR) methodologies using VMware virtual infrastructure. The session will explain in detail the architecture used to set up a physical to virtual DR environment and will include examples from the deployment of a major banking company that created a DR site by reproducing its production environment with virtual machines on five physical servers.

What is Disaster Recovery?The process of restoring an operation after an interruption in service, including equipment repair/replacement, file recovery/restoration, and resumption of service to users. www.ni2ciel.org/Glossary/d_glossary.html“Recovering Quickly”NOT Business Continuity
Why Disaster Recovery?“Between 60-90% of companies that don’t have a proactive disaster plan find themselves out of business within 24 months of experiencing a major disaster”
- The Definitive Handbook for Business Management
Importance of Disaster Recovery Solutions
In the past, backup & recovery was ‘best effort’Today’s standards are different
More reliability is expectedFaster pace of business ⇒ more critical changeIntense competitive environment requires high service levels
Number and severity of threats are increasingTerrorism, natural disasters, viruses, hackers, industrial espionage, human error
Not implementing disaster recovery puts business at risk
Every year, one out of 500 data centers will experience a severe disaster
Problems with Physical to Physical Recovery
Hardware cost Need to have a separate target recovery server that exactly matches each primary server
Long, lengthy process requiring manual intervention
Many steps necessary before one can start “single-step automatic recovery” from backup server
Uncertainty of successVery difficult to simulate environment for testingComplex processes, limited equipment availability complicate training of personnel
The Solution:Virtual Infrastructure
Disaster Recovery at Lower CostHardware / System / Application independence
NO NEED to worry about THE EXACT hardware configurationFlexibility to restore to any hardware
Application independent capture and recovery processesLess hardware required at “hot” failover siteSingle-step simplified capture and recovery
One step system and application recoveryNo Windows registry issuesEasy-to-automate recovery
Support for all capture / replication technologiesTape / MediaDisk-based Back upSynchronous or Asynchronous Data Replication
Improving Time to RecoveryRestore system and application data in one stepApplication / OS / hardware independent (crash consistent) backup and recovery processesNo need for 3rd party ‘bare metal’ restore tools
Reduce learning and ramp-upReduce software licensing expense
Use the same methodology through application lifecycleStagingDeploymentDR
Test once – recover anythingApplication independent recovery => simplified testing
Increased ReliabilityEnsure success
Easy to test and simulate in any environmentMinimal equipment requirementSimplified process and reduced personnel requirements

Physical to Virtual Recovery PreparationP2V Assistant performs all necessary substitutions to transform a physical system into a production-ready virtual machine
Creates an image of the source machine using either the VMware imaging tool or a 3rd
party imaging product
Performs all necessary HAL and driver substitutions to make the image bootable
User can manually modify any additional settings before having a production-ready system
Using P2V and Backup Software
P2V with Backup Software ConceptPeriodic P2V image to capture system stateSystem state includes backup clientStandard backup practice to take full and incremental backupsOn disaster, restore backup from tape to virtual machine
Physical to Virtual Recovery
Virtual machine templates with operating systems and backup agents are created and archived
Full system restore occurs into virtual machine using existing recovery agents
Using P2V and Third Party Live Imaging
P2V with Live Imaging Software ConceptUse 3rd party imaging to create image and periodic (nightly) incremental imagesStore images and potentially replicate to DR siteOn disaster, restore image into Virtual Disk using 3rd party restore processRun P2V to migrate OS to boot virtual machine
