Traditional disaster recovery approaches have limitations around cost, complexity, and long recovery times. Virtualization provides opportunities to simplify and automate disaster recovery management while reducing costs. Solutions like VMware Site Recovery Manager leverage storage replication between sites to automate the failover and recovery of virtual workloads, enabling non-disruptive testing and faster recovery. Specialized vendors also offer workload-focused solutions for virtual machine protection and recovery.

Disaster Prevention
• How Can we maintain uptime at the core location(s)
• Redundancy
• Diversity
• Power Protection
Focus on Continuity of Operations
• Categorize Applications for Criticality
• Standardize RPO and RTO according to Application Tiers

5. Application Categorization

acceptable Manual Failover
Tier 3 Important to the Protected by Remote $$$

1 Server Clustering 0 0 $$$$$$$$ Duplicate Hardware
Complicated Setup
Limited Use
2 High-end replication Minutes Minutes $$$$$ Complicated Configuration
Duplicate Hardware
3 Disk Imaging 24h Hours $$$ Limited restore and flexibility
4 Tape/Manual Rebuild 24h+ Days $ Difficult to administer
Slow, prone to errors

7. Audience Discussion
• What Categories have you identified for Applications
• What RPO/RTO have you defined.

8. Traditional Methodologies
Traditional Approaches to BC and
DR solutions have limitations
• Tape Backup and Offsite Storage
• Data Protection Only
• Very Long recovery time
• Difficult and expensive to test
• High End Storage Replication and Hardware Clustering
• Expensive
• Solutions specific to applications
• Bandwidth Intensive
• May not support geographic separation

11. Impact of Virtualization
• Virtualization is an obvious Game Changer
- Removes Hardware from the equation
- No longer necessary to maintain identical storage or hardware
- One-to-one relationship not needed between production and
recovery site
• Hardware independence allows for smaller recovery
site and greater efficiency
• Network Independence – NAT for Legacy Applications
• Testing can be done in a silo environment
• Test Time Objective (TTO)
• Not a Panacea

12. Impact of Virtualization
• Reduce Total Cost of Ownership/Operations for
Business Continuity
- Ease of Administration
- Fewer physical Resources Required for Recovery
- Recovery performed by IT Generalist vs Specialist
- Recovery infrastructure is flexible and scalable for the future
• Workload Protection
- Migrate from box protection to application continuity
- A workload encapsulates the data, applications and operating systems
that reside on a physical or virtual host
- Integrated Snapshots provide for shorter Recovery Point Objectives
