4. Disaster Preparedness Checkpoint #1:
Are Disasters Viewed as a Real Threat?
Disasters never really happen.
It’s just a vendor sales gimmick…

5. Why Is This Area “ Vital ” ?
Expectations of the IT Services are demanding
Technology is an enabler of business
Penalties are becoming more severe
Business is becoming more competitive
Businesses rely more heavily on their enterprise applications
than any other time in history

6. What is a Disaster ?
ANYTHING !!!!
That stops your business from functioning & that cannot be
corrected within an acceptable amount of time….
7. What is Disaster Recovery?
Reaction to a sudden, unplanned event that enables an
organization to continue critical business functions until
normal business operations resume.
“…It is not enough to arrange for hardware replacement;…
planning must address continuation of business operations, or
business continuation.”
8. Common Issues with Disaster Recovery Planning
We tend to let our guard down when times improve.
As planners, we must always be ready and prepared.
• Are the expectations of your DR plan realistic?
• Has your plan kept up to date with your IT integrations?
• Do you have a qualified staff to execute the plan?
• Is DR integrated into your Change Control process?

Primary assets needed to operate Information Systems:
• Hardware and networks can be replaced
• Facilities can be rebuilt or relocated
• Your Data is Priceless !
• People are assets too!

13. The Products of the Plan
Who will execute recovery actions
What is needed to continue, resume, recover or restore business
functions
When business functions and operations must resume
Where to go to resume corporate, business & operational functions
How detailed procedures for continuity, resumption, recovery or
restoration

Does your business know what
your IT department can deliver?

17. Categorize Your Technology Inventory
as Critical vs. Necessary vs. Not at All
Typically look for a 60, 20, 20 breakdown.
• 60% of all your servers are critical for recovery
• 20% are necessary but not required immediately
• Remaining 20% are optional or not required at all.
This means you can focus on 60% not the 100%.

18. Email
It has become Mission Critical.
It represents a way you communicate with
customers,
partners, employees, and the world.
Imagine no Email !!
Should EMAIL be an H/A application?

20. How Much Data Can You Afford to Lose?
• Lost data is lost money!
• Most IT shops depend on tape backups to protect their data
• Data considerations for tape
• Minimum of 24 hrs. of lost data
• Application access may be more critical

24. Checkpoint #4: Backups
Build it and they will come.
Put into practice what you
say you will do.
24 August 29, 2012 Velocity Proprietary and Confidential
26. Tape Backups - Pros
Easy to run
Easy to manage – Tape Management Products
Easy to Automate – Automation Software Solutions
High Speed & High Capacity reduced backup windows
Capacity of tapes reduces number of Tapes
It’s the way we have always done things
Virtual tape libraries
Local Electronic Backups
27. Tape Backups - Cons
• Media, interface, or drive errors
• Seldom validated – How do you know your backups are valid?
• Time to ship, travel and restore tapes at Hotsite in a disaster
• Loss of data because backup only runs once per day
• Backups omitted in lieu of system access
• Lost tapes – Misplaced!

How many people backup their system ?
38% are in-complete
19 % iSeries ( AS400) are un-recoverable
32 % Windows are un-recoverable
30 % Oracle DB are un-recoverable
15 % Virtual Infrastructure un-recoverable

31. Backup/Recovery Best Practices
• Examine your backup strategy and policies for data
• Review backup strategy and policies for server infrastructure
Document server related information with signoff
• Are your network configurations backed up?
• Review off-site tape and vital records storage strategies
• Have you audited your backups?
• Can you demonstrate recovery procedures for daily, weekly, and
monthly backups?

32. Checkpoint #5:
Building a Recovery Team
Getting the right people:
Do they have the Right Stuff?
32 August 29, 2012 Velocity Proprietary and Confidential
33. Perspective
Too often, companies populate their DR teams with raw or
inexperienced staffers
Volunteers to satisfy an auditor or the sacrificial lamb
34. Ideal Team Member Characteristics
• Considered an expert by his or her peers
• A go-to person for anything and/or everything
• Works well under pressure
• Sense of urgency, willing to fix problems created by others
• Confident
• Trusted by peers
• Dedicated – A company person

35. The Effects of an Unprepared Recovery
Staff Are Real
Recovery is only possible if your staff is available
to put IT back together again.
Disasters affect people in unpredictable ways:
• It can devastate people both physically and mentally
• Can effect others around them
• Make the individual unable to function
• Emotional breakdown
Respect the situation!
35 August 29, 2012 Velocity Proprietary and Confidential
36. The Role of Executives
Executives are not typically involved and should NOT be.
Why:
• Executive Pressure is hindering
• Intimidating
• Often Nasty
• Glorified Experts
The team must provide regular status reports & the
Executives should be accessible when required.
37. Best Practices During a Disaster
• Feed your staff - Have snacks handy
• Stay away from High Energy Drinks
• Enforce no shift duration to exceed 12 hours
• Encourage people to take breaks
• Provide distractions during breaks
38. Irene was no lady!
Family Comes First
People Evacuated
2, 465, 000
Until the basic personal needs are met
• Family comes first. Always !!
• Staff members will not focus on the Enterprise recovery
• Staff members may or will not be available

47. DR Scenario – Without Virtualization
Hardware Gap - Your Production & DR must always be equal
Gap grows as new severs are deployed

49. With Virtualization
Break dependencies between OS
and hardware
Manage OS and application as
single unit by encapsulating
them into VMs
VM’s are hardware-independent:
they can be provisioned anywhere

52. Checkpoint # 8: Testing your DR Plan
It worked last year.
Nothing has really changed…
52 August 29, 2012 Velocity Proprietary and Confidential
53. It’s not all bad news if your plan fails
during a test…
Frequent testing identifies gaps in your recovery process
53 August 29, 2012 Velocity Proprietary and Confidential
54. Passive Testing
• Hands on plan review
• Paper walkthrough
– Assessment of current Recovery Plan
– Assessment of risk areas
– Involve every member of your recovery team.
This includes the business and management!

55. Active Testing
Validates the Recovery Plan in terms of:
1. Recovery capabilities and abilities
2. Alternate site configuration
3. Network recovery
4. Offsite records
5. Identify weaknesses in the plan
6. Provides training
This all equals success during a disaster
55 August 29, 2012 Velocity Proprietary and Confidential
56. Testing / Hotsite Best Practices
• Examine your hardware schedule in your DR contract
— Check for back level compatibility
— Do you need additional capacity?
— Performance Profile – Have database requirements changed?
— Travel and expenses
• Avoid testing from “special” backups
• Test your entire technology infrastructure
• Train your alternates
• Evaluate vendor performance
• Make sure your “hot box” is current for vital records
