TOP 10 TIPS ON DISASTER
RECOVERY

2. Top 10 Tips for Data Recovery
• What would happen to your business if you experienced a
catastrophic data loss?
• Would your business survive?
• The statistics are alarming, 43% of businesses never re-
open after a major disaster.
• A well planned data recovery strategy can deliver
improved resilience with predictable costs and no
unscheduled downtime.
• It will also allow you to sleep at night!

3. 1. Identify your data recovery needs
• Data Recovery is vital for the survival of your business.
• Your data defines and separates your business from any
other in the market.
• If failure should occur at any level of your infrastructure it
can be felt across the business.
• You must ask yourself, how would your business survive a
disaster?
• And what provisions do you have in place for your
business to continue after?

4. 2. Understand the risks
• Data loss can range from the accidental deletion of files to
the failure of your entire site.
• Without data recovery precautions in place you are
putting your organisation at risk.
• IT failure is the most common threat to businesses
• The threat of fire and natural disaster can have the most
devastating consequences.
• Findings from a CBI study indicate that a high level of
disruptions in 2008 and 2009 were due to extreme
weather incidents such as snow, flood or high winds

5. 3. Assess the criticality of your data
• The key aspect of data recovery is understanding just how
critical your data is.
• By compiling an assessment on the risks to your business
you can then develop a tiered recovery strategy
– Mission critical data
– Important data
– Legacy data
• This will ensure all levels of your infrastructure can be
recovered in the event of a disaster

6. 4. Assess how easily you recover a file
• Data backup is required by all businesses
• With legal requirements tightening and growing data
volumes, tape backup is no longer reliable /cost effective
• Managed Online Data Backup Services enable you to
instantly recover files within seconds
• They deduplicate data to make the most of your storage;
saving resources and reducing costs.
• Data is securely encrypted during the backup and is ready
for recovery if needed

7. 5. Consider impact of a server failures
• Assessment for data recovery calls for you to consider the
maximum amount of downtime you can afford for any
system before the impact becomes critical to business
operations.
• You can define your data recovery policy according to:
– how critical that system is
– the chance of failure
– how much you are willing to spend to minimise
recovery time

8. 6. Assess your system recovery
• The process of re-installing an operating system, its
service packs and updates, along with applications and
new device drivers can take hours or even days,
contributing to your overall recovery time.
• Prior to the lengthy process of application installation and
data restoration, a compatible system is required, adding
yet more downtime to that ticking clock.
• The reality is that system failure could result in over week
of downtime till your system is back up and running

9. 7. What is the impact of downtime?
• For most organisations, to be without a particular system,
for any length of time could result in the loss of business.
• Should the system running your website fail, the chances
are customers will not return.
• It is vital that you can recover your systems as quickly as
possible, reducing downtime and limiting loss of business.
• Essentially, any length of downtime can be harmful to
your business, but extended downtime could spell out the
end

10. 8. Assess system recovery methods
• Assessing the critical levels of your data and systems,
allows you to set a data recovery policy that works best for
you depending on your Recovery Point Objective (RPO).
• Bare metal recovery to recover to either your system to
similar or dissimilar hardware.
• Online disk backup allows you to increase the frequency of
your backup for more dynamic and rapidly changing data.
• You have the flexibility of backing up more frequently on
critical systems and less frequently on non-critical systems.

11. 9. Consider your network for DR
• Putting a resilient data recovery policy in place insures
your data against failure, but what about your network?
• Your network infrastructure is vital to continuous running
of your organisation.
• A disaster on site will take out your network and data.
• Hosting your network with a service provider offers you a
fully managed solution for network recovery.
• Your network will be accessible even in site failure,
ensuring that your business continues as normal.

12. 10. Consider to offsite your IT estate
• Managed hosting is the ultimate business continuity
solution.
• Not only can you host your data, systems and network
safely offsite in the service providers 'cloud'; you can also
protect your telephony systems in the same way.
• Service providers such as InTechnology offer a portfolio of
hosted cloud services to protect your entire infrastructure.
• Hosting your IT infrastructure in the cloud covers every
aspect for business continuity and allows you access to
extra computing resources when you need them.

13. What options do I have?
• Primary environment in the cloud
• Primary communications services in the cloud
• Data recovery services
– Online Backup
– Online Replication
– Virtual DR environment

14. Primary environment in the cloud
• Infrastructure as a Service enables you to access one or
more virtual machines, and run applications
• Virtual servers run on physical servers located in a service
provider data centre.
• The virtualisation software abstracts processor, memory,
storage and networking resources into multiple virtual
machines, delivering greater utilisation and flexibility, and
unparalleled levels of performance and scalability.
• Due to data centre and physical infrastructure resilience
and the fact that the environment is already offsite, DR
requirements are minimal

15. Data recovery services
• File Recovery Services
– Unintentional deletion of data from a
server
– Recovery of a single file back to an
otherwise working system
• System Recovery Services
– Hardware or software failure of a server
– Rebuild of a specific server at current
site
• Site Recovery Services
– Complete failure of a customer office
– Require rebuild of application
infrastructure at alternative site

Step 1: Customer orders and

Step 2: Customer
installs O/S and
Application Software
Step 3: Backup Data
is delivered by
service provider to
customer site, either
over wire or
physically by
portable storage

20. The problem is downtime
• To recover 1TB of server data takes a minimum of 28
hours
Copy 1TB to portable storage: 10 hours @ 100GB / hour
Ship storage to site: 3 hours
Restore to new server: 15 hours @ 70GB / hour
TOTAL 28 hours
• Larger data volumes take proportionally longer, and
recovery over the wire is not an option for data volumes of
this size
• This is in addition to the time to take delivery of a new
server install the O/S and application software

22. Site Recovery Management

23. Site Recovery
• Site Recovery is a variation of the System Recovery
options with the below exceptions:
1. There will be multiple servers to simultaneously
recover, so restoration times need to be considered
2. Other systems, such as telephony, will also be affected
3. Staff will also need alternative premises to work at

26. SUMMARY/
• You need to consider your DR
requirements end to end
• Critical systems and critical data
• Consider moving primary IT
environment into the cloud
• By combining existing
backup, virtual hosting, voice, co-
location, and storage
services, service providers like
InTechnology can address full
scale DR requirements
