DESCRIPTION
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.

The State of Disaster Recovery Today
The recovery challenge… 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
Less than half of firms have a disaster recovery plan
10
The Disaster Recovery Challenge
Capacity requirements are still growing 20%-40% per
year
More and more companies operate
close to 24x7
BC/DR budgets are 5.5% of IT
opex/capex
Data explosion
Increasing recovery demands
More complexity and
heterogeneity
No tolerance for data loss
Less budget allocated to
BC/DR
25% of servers are non-Windows OSes
Business owners have less and less tolerance for any
data loss

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

Failover is manual, requires skilled staff. Public cloud provider does not usually guarantee any capacity when needed nor will they assist in the failover. If physical servers are being protected, customer must manage the conversion to virtual.

Primary Storage
DRaaS provider
Production data centersService provider deploys agents to replicate data and applications to the cloud. Physical machines are converted to VMs to boot in the cloud.
Primary Storage
VMware VMs and file shares stored on an array are replicated using storage replication and recovered on like storage in the cloud

Varying Levels of RTO/ RPO
17
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

Benefits of Cloud-Based DR
18
Better functionality for
less cost
• Most of the time, you essentially only pay for storage resources, turning on VMs only in the event of a disaster invocation or a test
• Little to no upfront investment is required
Easier, more frequent, and less expensive testing
• Testing can be automated and non-disruptive. DRaaS contracts usually include testing services and failover assistance
Easy, more flexible, enables
chargeback
• Gives you the ability to adapt to changing IT environment and business needs.
• Deployments are measured in weeks, not months to years
Pay-as-you-go pricing
• Pay per protected server makes operationalizes DR spending, makes it easy to add additional protected servers or storage, avoids bursty capex and enables chargeback
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
19
How Does DRaaS Work?
20
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)
21
The Power of DRaaS
22
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 backups
Restore entire environment in little more 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
