Step 1: Build And Refine A Clear DR Policy To Match
Business Needs And Requirements
§ RPO (Recovery Point Objective). Is defined by business continuity
planning. It is the maximum tolerable period in which data might be lost
from an IT service due to a major incident. The RPO gives systems
designers a limit to work to.
§ RTO (Recovery Time Objective). Is the targeted duration of time and a
service level within which a business process must be restored after a
disaster (or disruption) in order to avoid unacceptable consequences
associated with a break in business continuity.

Speed and improved BC/DR are the biggest
drivers for cloud adoption

Step 2: Implement And Enforce DR Testing
Policies

Step 2: Implement And Enforce DR Testing Policies
§ Test after every change/upgrade/backup
§ Test servers at a minimum
§ Test things in combination to ensure you will have a successful recovery
when needed

Step 3: Geography Matters! Leverage
Cloud And Colocation Failover Sites

Step 2: Geography Matters! Leverage Cloud And
Colocation Failover Sites
§ Utilize multiple sites when possible to maximize protection
§ Make sure sites are a safe distance apart to avoid the impact of a major
disaster
§ Clouds and collocation sites are becoming more popular for DR for
increasing accessibility and to handle peak loads

In-house sourcing recovery is still favored

Step 4: Warm Up Recovery Sites For Key
Apps

Step 4: Warm Up Recovery Sites For Key Apps
§ Make sure failovers can happen with minimal intervention
§ Negotiate readiness SLAs with your service provider to make sure mission
critical workloads have low RPO and RTO.

Recovery Time And Recovery Point Actuals
Lengthen In 2013

Like on-premise DR, recovery sites vary in temperature
› Hot cloud site: Recovery cloud is running replica VMs to
production site using real-time replication.
• Recovery time objective (RTO) : 0-2 hours
• Recovery point objective (RPO): 0-24 hours
› Warm cloud site: Recovery cloud contains offline copies of virtual
machines that can be spun up during disasters or tests.
• RTO: 2-6 hours
• RPO: 0-24 hours
› Cold cloud site: Recovery cloud contains backups of production
systems that must be first rehydrated and turned into VMs before
recovery can occur.
• RTO: 4-24 hours
• RPO: 24-48 hours

Think resiliency, not recovery
Recovery
Implies downtime and that systems
must first suffer an outage before
they can resume normal operations
Resiliency
Refers to the ability of a business to
spring back from a disruption to its
operations without an outage

Step 5: Analyze Your Networking Needs

Step 5: Analyze Your Networking Needs
§ Configuration. Make sure primary and DR site configurations are synced
including key services like DNS.
§ Connectivity. Test connectivity at your DR failover sites to ensure the
replacement servers can communicate
§ Bandwidth. Adequate bandwidth must be provisioned at the failover sites.

Step 6: Fortify Your DR Environment

Step 6: Fortify Your DR Environment
§ Security. Secondary sites need to be secured just as much as primary
infrastructure.
§ Backup up your DR sites. The secondary site becomes a single point of
failure without a backup.

Step 7: Expand The Value Of Your DR
DR is more than an insurance policy!
§ Workload migration. In the future the technology in DRaaS will be used to
facilitate workload migration and cloudbursting.
§ Test/Dev. Is a good use case for DR infrastructure.
