Disaster Recovery as a Service

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.

Disaster Recovery as a Service

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
