Recovery: The Problem
Restoring IT Infrastructure – Not Just Single Servers
Forrester and DRJ asked 200 readers:
Were you able to recover
from your most recent
disruption in less than one
hour?
30% responded yes
In 2010, 13% responded yes
In 2013, 2% responded yes
In 2007,

Change is Why; Today’s Change is Virtualization
•
Storage Tuning
•
You need Granularity at
HOS/GOS/application level
•
We have Hyper-V gaining ground on
vSphere
•
We have development Containers and
Docker poised to challenge
•
There are Hybrid, private, public clouds,
and now bare metal clouds
•
We have AWS leading; But Azure
accelerating fast
•
And so much more…
Adaptability to the increasing pace of change…

Seven Shortcuts to Losing your Data
Ignore potential hardware failures
Trust your fellow co-workers to do the right thing
Disregard potential software corruption
Rely upon the honesty of others
Pay no mind to computer viruses
Play the odds on disasters
Take recovery for granted

What is a Disaster?
•
Catastrophic Act of God?
•
Malicious Employee, Hacker, Terrorist?
•
HW or SW failure?
•
Corrupt data being replicated?
•
Oops! I guess I really needed that file?

Definitions: RPO & RTO v RPA & RTA
RTO – Recovery Time Objective
>
How quickly should critical services be restored
RPO – Recovery Point Objective
>
What Point should data be available (how old can the data be)
RPA – Recovery Point Actual
>
At what point did I actually recover (how old is the data)
RTA – Recovery Time Actual
>
How long did it really take

How to Start
Sort your Cattle, Pets, & People
We expect loss with Cattle and just make hamburger
We know Pets will pass but we try to extend their lives
We will go to the ends of the earth to preserve People
Sort your applications the same way

Taking Another path
Be prepared – Assume the worst
•
•
•
•
Plan for hardware failure
Minimize tape use
Use automated backup policies
Use retention for recovery from software corruption,
human maliciousness, and viruses
• Think Hybrid – On-premise and Offsite (esp. in the cloud)
• Use disaster recovery to avoid fatal consequences of
disasters
• Test your DR plan!

Key Components to a Great Backup and Recovery Solution
• An integrated appliance as well as a SW based solution
• Backup of the Physical and Virtual operating systems all-in-one
• On-premise backup device for immediate restore of (minor disaster) issues
• Replication and an extension to the Cloud for (major disaster) issues
• An archiving capability to tape, removable HDDs, and the commercial Cloud for data retention
• “Backup Audit” mode testing to confirm individual machine recovery
• Instant recovery for critical Physical and Virtual machines
• Automated “service level” DR and SLA testing to confirm application level recovery (with DR orchestration)
• SLA compliance reporting for IT management and LOB owners

Best Practices
These best practices fall into four main categories:
1. Implement & proactively train on detailed DR plans




When, Where, Who, What apps
Roles & Responsibilities, Expectations, Hand-offs
Phones, Wireless, Cell, Desks, Laptops, Travel, Lodging, Food
What's not allowed (Facebook, YouTube, Streaming media)
2. Set specific DR metrics for RTOs and RPOs
 From your BoD or LoB
3. Test DR plans much more frequently
 Have you ever tested?
(Who has the time?)
4. Spend at least 2% of total IT on DR oriented items

Cloud Questions & Considerations
How much CapEx are you saving vs monthly cloud service fees?
Are you comfortable with the manageability and control of your data?
Are you able to seed the cloud with any sort of direct access?
How (and how quickly) can you recover from a real disaster from the cloud?
How much “trust” do you have in your cloud service provider?
Could you pass a compliance audit of your data in the cloud?

Thoughts to Ponder
"...the business doesn’t care about IT. The business will only care about what it can do to
generate more business…”
Gartner, Daryl Plummer, 12/2011
"80+ years ago, most companies generated their own power because power companies either
didn’t exist in the area or they were not secure, not reliable, not affordable, and not clean
sources of power…”
Think “Cloud”: Show the strategic business value of IT and provide positive business outcomes
that transform your company...its about business, not technology

The Competitive Landscape
For Hybrid Cloud DR Strategy
The Model T
• 1908-1927
• Longest production run till the Beetle in 1972
• 15 million vehicles produced; Made Henry Ford the richest man in the world
• Good solution but:
• Initially no options (no choices)
The Competitive landscape
• Off-premise (only)
• Software (only)
• Virtual Machine backup (only)
• Resource licensing (only)
• Base licensing, +++ (only)
• Good solution but:
• No options (no choices)
• None on the horizon
