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


DR Testing Is Trending Upward, But Updates Still Need Improvement May 2014 “The State Of Business Technology Resiliency, Q2 2014”

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 May 2014 “The State Of Business Technology Resiliency, Q2 2014”

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.
