Disaster recovery traditionally means investing in a secondary site full of infrastructure that will rarely be used. Not only is the economically prohibitive for many firms, but managing both the deployment of the DR plan and its ongoing upkeep is at best a distraction for the IT organization. DRaaS provides continual replication of your key servers to our cloud with managed recovery of a clone of your servers in our cloud on demand.

10. The State of
Disaster Recovery Today
Less than half of firms have a disaster The recovery challenge…
recovery plan  38% of companies back up mission-critical
applications/data to tape, and manually
transport them offsite (Forrester/DRJ)
 The average time to recover after a disaster
was 18.5 hours, up from 17 hours in 2007
(Forrester/DRJ)
 Companies lose an average of $84,000 every
hour of downtime (IDC)
 Yearly cost of downtime at almost one-third of
companies is estimated at > $3.9MM
(Aberdeen)
Key Challenges
 Don’t consistently backup/ replicate data off-site
 No infrastructure to recover to or test with
 Lack of skills & available personnel in emergency to do complex recoveries
 No real-world experience recovering complex applications
 Growing volume of data with new complexity from virtualization 10

13. 3 Categories of cloud-based DR
Cloud-based DR
Do it yourself Cloud-to-cloud DR-as-a-Service
cloud-based DR DR • Pre-packaged
• Using the public • The ability to solutions that
cloud to architect a failover services provide failover to
custom solution from one cloud a cloud
leveraging the data center to environment
agility and speed of another
the cloud.

17. Varying Levels of RTO/ RPO
 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

18. Benefits of Cloud-Based DR
• Most of the time, you essentially only pay for storage
Better resources, turning on VMs only in the event of a disaster
functionality for invocation or a test
less cost
• Little to no upfront investment is required
Easier, more • Testing can be automated and non-disruptive. DRaaS
frequent, and less contracts usually include testing services and failover
expensive testing assistance
• Gives you the ability to adapt to changing IT
Easy, more environment and business needs.
flexible, enables
chargeback • Deployments are measured in weeks, not months to
years
• Pay per protected server makes operationalizes DR
Pay-as-you-go spending, makes it easy to add additional protected
pricing servers or storage, avoids bursty capex and enables
chargeback

19. What is DRaaS?
 Disaster Recovery as a Service (DRaaS)
 Combines the best of replication, cloud and virtualization technologies
 Delivers a fully-managed recovery to a cloud-based disaster recovery
infrastructure
 Ensures your data and applications are safe and secure, and will be
there when you need them most

20. How Does DRaaS Work?

21. The Flexibility of DRaaS
 Multiple replication methods:
 Host-based replication for heterogeneous physical
and virtual environments
 For EMC-powered data centers, with managed EMC
RecoverPoint Appliances and Replication Manager
support
 For NetApp-powered data centers, with managed
SnapMirror / SnapVault replication and support for
SnapManager
 Application-layer replication using running VMs (Ex:
Exchange Database Availability Groups)

22. The Power of DRaaS
Traditional DR Windstream Hosted Solutions DRaaS
Increased hardware and storage Leverages cloud economics and
economies of scale
Typically limited to 24 hour RPO Variable RPO down to 15 minutes with
application consistency
Long RTO to restore manually from Restore entire environment in little more
backups than server boot time
Difficult and time consuming to test Off-loads restore burden on provider,
customer only has to validate applications
Requires significant architectural work Pre-designed and validated for common
environments
