Disaster Recovery & Business Continuity

What is DR and BC?

• Process, policies and procedures related to preparing for recovery or continuation of technology infrastructure critical to an organization after a natural or human-induced disaster

• Scope is limited to technology and technology availability

Disaster Recovery (DR)

• Planning out how to stay in business in the event of disaster• Scope encompasses all critical business operations (sales,

customer support, financial and admin services, etc)

Business Continuity (BC)

While not the same, they are tightly interdependent.

DR Site Design Options

Duplicate of the original site of the organization, with full IT systems as well as near-complete copies of user data.

Have hardware and connectivity already established, though on a smaller scale than the original production site or even a hot site.

Standby site with no hardware, established connectivity, or backups, but has adequate facilities to house IT infrastructure.

No specific facility, but a plan to have employees work from home from the Cloud.

Hot Site Warm Site Cold Site Mobile Site

RTO and RPO

Maximum tolerable length of time that a computer, system, network, or application can be down after a failure or disaster occurs

Recovery Time Objectives (RTO)

Age of files that must be recovered from backup storage for normal operations to resume (aka how many hours of work is lost)

Recovery Point Objectives (RPO)

Your Risks

“80% of companies that suffer a disaster and have no DR plan go out of business within 18

months.”

Fact or Fiction?

FALSEThis is a popular urban myth.

The Reality of the Situation

The average amount of money estimated that companies lose every hour of downtime.

According to Strategic Research, the cost of downtime is estimated at close to $90,000 per hour.

$84,000-International Data Corp

The Reality of the Situation

In 2008, the United States was the top country for overall malicious

activity, making up 23 percent of the total.

According to Timesavers International studies, the catastrophe most businesses experience is not fire, flood or

earthquake, but rather something much more insidious:

Malware!

The Reality of the Situation

of all PCs will suffer an episode of severe data loss in any given year, resulting in approximately 4.6 million severe data loss episodes.

6%

The Reality of the Situation

of PC users have lost all of their files due to events beyond their control.31%

The Cost of Data Loss

Data loss cost US businesses $18.2 billion!

Causes of Data Loss

Risk Analysis

Determine appetite for downtime (RTO) for each system

Rank your IT systems by impact on business operations

Determine impact of data loss for each system (RPO)

Likely risks like hardware and network failure should go at the topUnlikely risks like tornado should go at the bottom

Rank the risks to that system by likelihood to occur

Look for projects that address multiple risks and/or systems and/or non DR needs (better ROI) Be sure to identify dependencies

List options to address each risk, rank their effectiveness, and estimate cost

This Risk Analysis creates a roadmap to address your DR needs!

Instead,Perform a basic Risk Analysis:

Data Recovery for your entire IT Infrastructure is very expensive!

Planning

•Must include all executives•Good DR plans involve more than the IT department

Corporate buy-in is critical to success

Establish a budget - budget drives your options

•It is more difficult and more costly to design DR for production systems

Planning should be part of the production design

Use your Risk Analysis to establish a multi-year project plan

Planning

Document, document, document!

•Be sure that your documentation is available no matter what the disaster!

Plan your actions – who, what, where

Test and update regularly – a stale DR Plan is a useless DR Plan

Virtualization and big bandwidth are key enablers of DR in 2013

Minimum Disaster Precautions in 2013

Daily backup strategy with at least weekly

offsite backups

A strategy for monitoring and

remediating problems with your backups

Antivirus software on all workstations and

servers with daily signature updates

Patching on all workstations and

servers kept up to date

High Availability = Disaster Prevention

typically means that the system is automatically redundant. Eliminate single points of failure!

High Availability (HA):

Enables very low RTO and RPO objectives

Network High Availability

Dual routers Dual firewalls Dual switchesDual network interfaces on

High Availability Connectivity

Dual connections to the Internet

•Difficult and expensive to implement at a corporate level•Need to use two separate carriers – very little protection if using the same carrier•Multi-site companies can use another site’s Internet

Dual connections to remote sites

•Use separate carriers•Use separate last mile media (T1 and Fiber, T1 and Cable)•Easy and relatively inexpensive using Internet as failover with mesh VPN technology

High Availability Power

Install quality power filtration and lightning arrestors

Use devices with dual power supplies

Where that isn’t possible, use an Automatic Transfer Switch (ATS)Note that an ATS creates a single point of failure

Feed devices with two separate power circuitsBetter yet, feed from two separate power panels

Protect at least one circuit of each pair with an Uninterruptible Power Supply (UPS)

Protect the UPS(s) with a generator

Virtualization = Server Hardware HA

Virtualization is the key enabler of server hardware

HA

Divorces server software from the underlying hardware running it

Allows a server to “move” between multiple physical

server hardware

Enables rapid replacement or expansion of physical

hardware on demand

Enables new backup techniques that have less

impact on servers and users, and allows for much faster restore times. Bye-bye bare metal restores!!

Most importantly for disaster recovery, allows

servers to “move” between multiple physical locations

Application HA

Virtualization addresses hardware failures but

doesn’t address application failures

•Exchange 2010 Database Availability Groups (DAG)•Microsoft SQL Clustered Services•Microsoft SQL Bidirectional Transactional Replication•Windows Server 2008 DFS

Native Application HA implementations are

typically the most effective way to address

HA for specific apps

Native Application HA Schemes

Geographic HA

• Typically proprietary

SAN based (LUN to LUN)

• DoubleTake• Microsoft SQL Replication• Microsoft Exchange lag database copies• Microsoft DFS Replication

Server or Application Based

• Veeam Backup and Replication

Virtual snapshot based

All these techniques require high bandwidth connectivity
