Can your business survive the next disaster?Ashish Patel
Did you know that 40% of businesses do not re-open after a disaster? Or that it could cost an organization up to $600,000 per hour during a disaster scenario? In today’s “always on” world, businesses must continue to operate no matter what, which means that critical IT infrastructure must be available 24/7/365. In this session we will learn more about a holistic approach towards business continuity & IT resiliency and how organizations can achieve high levels of availability. We will also go over each stage of the business continuity lifecycle and talk about the importance of managed services, key processes and technologies that must be considered for a comprehensive Business Continuity & Resiliency plan.
Disaster Recovery: Develop Efficient Critique for an Emergencysco813f8ko
Disaster recovery will be the procedure, policies and procedures that are associated with getting yourself ready for recovery or continuation of technologies infrastructure that are vital for an organization following a natural or human-induced catastrophe. Disaster recovery is really a subset connected with business continuity. While business continuity entails planning for maintaining all facets of a company functioning in the midst of bothersome occasions, disaster recovery targets the IT or technology techniques that support company features.
Business Continuity for Mission Critical ApplicationsDataCore Software
Unplanned interruption events, a.k.a. “disasters,” hit virtually all data centers at one time or another. While the preponderance of annual downtime results from interruptions that have a limited or localized scope of impact, IT planners must also prepare for the possibility of a catastrophic event with a broader geographical footprint.
Such disasters cannot be circumvented simply by using high availability configurations in servers or storage. What is needed, especially for mission-critical applications and databases, are strategies that can help organizations prevail in the wake of “big footprint” disasters, but that can also be implemented in a more limited way in response to interruption events with a more limited impact profile.
DataCore Software’s storage platform provides several capabilities for data protection and disaster recovery that are well-suited to today’s most mission-critical databases and applications.

Kept up by Potential IT Disasters? Your Guide to Disaster Recovery as a Servi...VAST
There are many kinds of disaster that can shut down your information technology (IT) operations:
• natural disasters, like a hurricane
• power outages
• a hardware crash that corrupts data
• employees who accidentally or deliberately delete or modify data
• malware that tampers with, erases, or encrypts data so you can’t access it
• network outages due to problems at your telecom provider
Disasters happen, sometimes bringing down a single application, sometimes bringing down your entire data center. No matter how careful you are or how good your IT team is, eventually some event will shut down your applications when you really need them up and running. The Disaster Recovery Preparedness Council survey in 2014 found that 36 percent of businesses lost at least one critical application, virtual machine, or data file for a period of several hours, with 25 percent saying they’d lost a large part of their data center for a period of hours or days.
The costs of preparing for disaster can be high—at one extreme, companies maintain a secondary, standby data center with all the same equipment as at their primary site—but the consequences of not planning for disaster recovery (DR) can be even higher. The costs of downtime in 2016 ranged from a minimum of $926 per minute to a maximum of $17,244 per minute, with an average cost of close to $9,000 per minute of outage.
Those costs can completely cripple a business; Gartner found that only 6 percent of companies remain in business two years after losing data.
Creating an effective disaster recovery plan is a key step to ensuring business survival.

Performance differences your business may require to meet post-pandemic needs, and factors to consider before making an investment
As the post-pandemic economy grows, your organization faces both opportunities, such as supporting a growing customer base, and challenges, such as helping your employees thrive in the new normal. While there are still many considerations to balance when upgrading—including timing, budget, IT resources, and your current and anticipated needs—you may benefit from a server solution that can support workload requirements such as keeping digital transactions running smoothly and sustaining the websites for your business. Plus, a solution that offers the capacity and software features to natively support Kubernetes containers could add value by helping your organization get more from your hardware. When our testing concludes with the mixed workload that reflects these needs, our forthcoming report will detail the performance you may be able to expect from a cluster of 16G Dell PowerEdge single-socket servers powered by 4th Gen AMD EPYC processors compared to a cluster of legacy 15G Dell PowerEdge servers

A Disaster Recovery Plan is a documented process, and structured approach with instructions that details steps a business will take to recover from an unplanned catastrophic event. IBM highly relies on Information Technology to quickly and effectively process information, and most of its operations are computerized. As such, an IT disaster recovery plan for IBM should be well aligned with the business continuity plan. This is mostly known as risk assessment or threat analysis. Below are resources for documenting a disaster recovery plan for IBM Information Technology infrastructure.
Hardware and Peripheral devices
This generally includes any auxiliary device that is connected and works in conjunction with the computer, such as printers and scanners. When evaluating the hardware, one should determine the risk of losing the machine entirely and damage through hardware failure. The company computer systems may also be at risk of contracting viruses if employees are allowed to go home with laptops or consultants and vendors are allowed to plug in their Personal computers into IBM systems.
Email and Data exchanges
IBM uses shared computers and local area network which is generally a network of computers that share a communication line or wireless link to a server. This puts the company at risk of losing shared applications and information such as inventory control and payrolls. Sharing files using LANs may also lead to contraction of computer viruses and a slow down on the entire company network hence business interruptions. Emails shared through computers in the facility must also be evaluated when determining the risk.
Software Applications
IBM uses end-user programs designed to perform a group of coordinated functions for the fast and effective running of operations. These programs include word processors, spreadsheets, database programs and web browsers. All these programs are a source of vital information while developing a disaster management plan. Theft of software from the facility could be detrimental to the company and may even lead to lawsuits.
IP Addresses
The company internet protocol addresses act as a host or network interface identification. Despite the proxies and anonymity that exist to protect IP addresses, careless setups and gaps on the company’s security firewall could invite unwanted guests. Hackers may use the company IP address to send or retrieve information from the IBM computers.
VPN and Server Access
An evaluation on virtual private networks (VPNs) is necessary for ensuring the protection of private and confidential data. However, hackers may be able to spot weaknesses and stea.

Abstract
The Resource-Event-Agent (REA) model is a way to deal with conceptualizing the semantics of Fina Calculated models of undertakings can be utilized for both business procedure demonstrating and the genuine structure of automated data systems. The Resource-Event-Agent (REA) model, an area explicit structure for deciding the data engineering of bookkeeping and endeavor data frameworks, has fundamentally been utilized for plan purposes. In this paper we investigate the utilization of REA for business process modeling. At first, we talk about how REA natives are utilized to portray the esteem included change of assets all through the venture. Next, we break down some troublesome determination issues that identify with business procedure displaying when all is said in done and to REA designing answers for these issues. We finish up the paper with the detail of a three-layer engineering that abridges the REA way to deal with business procedure demonstrating: (I) endeavor level determination, (ii) REA-based procedure depictions, and (iii) task-level or work process specifications. The design demonstrates that work process portrayals can be identified with the detail of the venture esteem chain through the mode of REA data structures’ trades, for example, bookkeeping exchanges. The REA model is an ISO standard.

yet, if you skip key steps neglecting to collect key information prior to designing,
you can end up with an unwieldy DR solution that doesn’t meet the needs of the
business.
This eBook will serve as a checklist that can guide you on the creation of a
top-notch VMware disaster recovery plan. The checklist follows industry best
practices for implementing complex technology solutions by taking a phased
approach to instituting a DR plan. This approach includes the following phases:
• Assessment—Gathering key requirements for DR solution
• Design—Creating a DR plan to meet business and technical requirements
• Deploy—Stand up necessary infrastructure. Install, configure and test
solution
• Manage—Test your DR plan as frequently as possible
This approach should be reapplied as your business requirements change or to
take advantage of technology advancements that can reduce costs and enhance
DR capabilities. The result is a DR plan that is flexible enough to adapt with
the times and your business. Since we’re talking about recovery of VMware
environments, we will focus on leveraging its unique capabilities to the maximum
degree. The unique capabilities and properties of VMware environments allow us
to create the ultimate test-driven DR plan and help be a catalyst for moving to
100% virtualized environments. The focus of this eBook is the planning side of
DR and less on the execution and operation of the DR plan. As such, we'll focus
on the Assess and Design phases.

Business Impact Analysis
Let’s be frank. As cool as server virtualization technology is, it doesn’t provide
your business with revenue, unless you are company like VMware or Veeam.
As IT professionals, your job is to design, develop and manage the technology
systems that support the business’ ability to turn a profit. But equally important,
is the ability to restore these systems as rapidly as possible in a disaster. Before
you begin spending money on your disaster recovery software, hardware and
facilities, you need to know where to start. You should first assess your business
and gain an intimate understanding of which processes, systems and data are
most critical to the success and future survival of your company. This process is
referred to as a business impact analysis (BIA). Without one, you open yourself
to the risk of wasting resources or overprotecting assets of little value to your
business. Worse yet, without a BIA, you may end up neglecting to plan recovery
for key IT systems that your mission-critical systems depend on.
What's in a BIA?
A BIA can be as complex and time consuming as you want it to be. Complexity
and time are also a discrete function of the size and complexity of your business.
In either regard, all business impact assessments are looking to accomplish the
same fundamental tasks. For example, the following list was gathered from a
great free BIA template published by the U.S. Centers for Disease Control and
Prevention for the purpose of helping guide the development of a DR plan. In
this template, the following main areas of assessment are addressed:
Key BIA activities
1. Identify critical business systems
2. Identify system resource dependencies
3. Identify key support personnel or teams
4. Estimate disruption impact
5. Determine resource recovery priority
Having this granular knowledge of the business impact of your critical systems
not only will help you in a real disaster scenario, but it will help you test your
preparation for the disaster. Knowing where to focus your DR planning efforts
will help you greatly streamline and prioritize your disaster recovery exercises,
or tests.
The BIA is not just a technical system inventory, but you’ll need to work with
the business side to define RPO and RTO for key business services and the IT
services they depend on. Setting the objectives gives DR planners and managers
something to design and manage to. Without defining these key requirements
for your disaster recovery planning, you risk spending too much on a higher
level of data protection than is required. The other risk is that you don’t provide
enough protection for your critical resources and end up costing the business
time and money in the event of a disaster. In the following section, we’ll walk
through why RPO and RTO planning matters.
3
4. VMware Disaster Recovery Planning: Essential Checklist
Determine RPO and RTO
During your BIA, you should spend a good deal of time developing an intimate
understanding of how your business makes money and catalog the key resources
and processes necessary to enable revenue creation. In some companies,
thismay be a single business process that will translate to clear guidance on
RTO/RPO requirements. In larger companies, with diversified products and
services, you will likely catalog multiple use cases to address with different DR
strategies. Regardless of the business size, the process of DR planning is similar,
and we apply the same process to categorize the use cases we discover in our DR
assessments. The following are some example DR use cases. By reviewing these
common use cases and identifying their RPO/RTO, you should be able to apply
similar logic to your own business and gather these guiding requirements.
Educational Institution: Keeping costs low
On one end of the spectrum, would be a grade school with fixed budget based
on enrollment and no revenue generation based on system up-time. However,
the core product and service coming out of the school is the quality of the
children’s education. In an environment like this, it’s important to keep costs as
low as possible, but still provide a system that will reduce cost of recovery that
can likely call for third-party IT staff to help recover systems. Most systems can
withstand some loss of data and recovery needs to be timely, but certainly not
instant. Since schools can still operate effectively without IT, it is likely that a RTO
measured in days to a week will result from this assessment. The RPO would
likely be around 24 to 48 hours for most systems.
Accounting Firm: CDP during tax season
Throughout the year accounting firms do a certain amount of business and are
tolerant of 24 to 48 hour RPO and RTO. But in the United States, from February
through April, it is the busy tax season. Overtime and packed daytime schedules
are the reality. Data loss and system downtime is NOT an option. Near-zero
RTOs and RPOs are required for this use case. For the small and midsized firms,
expensive active-active accounting system designs are not an option, and
neither is expensive array level replication. This is a perfect use case for Veeam’s
SmartCDP. SmartCDP is a near-continuous data protection (near-CDP) solution
where virtual machines (VMs) are continuously replicated to a safe site which
brings RPO down to around 5 minutes and RTO can be as fast as the accounting
firm’s IT professionals and executives are ready to declare a disaster and restart
the affected VMs.
Healthcare: Ensuring quality patient care
In a healthcare setting there exists the perfect storm for DR planning. Today's
healthcare IT systems can actually be a profit center for many organizations.
These systems need to be functioning to allow profitable procedures like MRIs,
ultrasounds or any of the cardiac-related procedures. The profit side of the
equation is important, but not the only concern. In healthcare, patient care is
king. If technology is not available to serve patient needs, then the profits are
meaningless. Healthcare operates around the clock and pressures IT to deliver
services at a very high level. These highly critical systems demand a low RTO to
guarantee patient care goals are met and healthcare organizations can remain
profitable through systems disasters. Data loss isn't necessarily a financial risk,
4
5. VMware Disaster Recovery Planning: Essential Checklist
unless lawsuits are considered, but a high quality of patient care dictates that the
best patient health information to be available to ensure continuously good care
through shift changes and doctor rotations. So, in most healthcare organizations,
budget becomes the determining factor for what you'll end up choosing for RTO
and RPO. While working within your fixed budget, you may establish RTOs and
RPOs that are as low as possible during the times you require. Veeam Backup
Replication with its ability to back up, replicate and provide near-CDP in one
product, provides the flexibility to address all healthcare needs.
Understand Your Budget
Virtualized DR is much less expensive than traditional physical DR, but it is still an
additional cost on top of your already sizable investment in virtualization software,
supported server hardware and new storage systems. Some companies will have
the budget freedom to design the “Cadillac” of DR solutions. For the rest of us,
we have to be very aware of the budget limitations and the factors contributing
to that limitation. Knowing your budget limit and some key strategies will allow
you to optimize your DR plan to get the most capabilities out of your limited
resources.
Budget purchases wisely
One recommendation for DR budget planning is to consolidate all disaster
recovery options inside a single product so that you’re not paying twice for two
software products, two backup infrastructures and the associated operational
costs that can sink you. Instead, plan to make a strategic investment in virtualized
DR and go “all-in” with Veeam Backup Replication and drop strategies that
leverage legacy components. This can reduce ongoing license and support cost
as well as simplify operations, creating a substantial cost savings.
Phased Budget
Ideally, you should suggest a phased DR assessment budget by the business or
by your customer. In this method, you are allowed a fixed budget to conduct
your assessment and initial planning with the expectation the outcome will be a
more accurate budget estimation of the final solution. This method builds trust
with the business or customer and ensures them that you are not making these
recommendations on a whim and that the DR plan is exercising due diligence.
But once the assessment is complete and a preliminary design can be conducted,
you'll have to a decision to make in determining how much you will ask for.
Communicate the Vision
Just like companies and their initial server virtualization efforts realized, you may
have to spend money to save money in the case of virtualized DR. These first
pioneering IT organizations realized that the sooner they virtualized their entire
environment, the sooner they could start reaping the rewards of reduced power
consumption, reduced server hardware cost, and greater flexibility in operations.
Delaying ROI of virtualizing your physical servers was not recommended and the
same thing is true with a virtualized DR plan. The longer you have to maintain
a legacy DR solution alongside a virtualized one, the more risk your business
accepts, the more costly DR exercises are, and the more operational costs IT
departments take on to maintain two or more separate DR solutions. At this point
in the budget process, it's important to lay out the long term vision for 100%
5
6. VMware Disaster Recovery Planning: Essential Checklist
virtualized DR and communicate the benefits of legacy-free disaster recovery. If
business leaders understand the true value of virtualized DR, you should have
success funding the project properly to realize the full benefits. A good rule
of thumb is to shoot for the plan that can create the lowest TCO (total cost of
ownership) over the next 3 to 5 years.
Executive Champion
Virtualization can be a complex topic for business leaders to understand.
Throwing DR planning on top of that can sometimes put non-technical leadership
into a corner they are uncomfortable with. To make sure you get the DR plan
your company needs, you'll need to understand the concerns and realities of
the business, and be able to clearly communicate the solution's benefits to
the company. If you are dreading these conversations you should consider
identifying an executive champion to get involved. This champion is usually an
executive familiar with IT but accustomed to planning with other executives and
speaking at a technical level they can understand. For companies without formal
technology executive positions like a chief information officer (CIO), an executive
champion dedicated to DR planning project can be a critical component.
Understand Application Dependencies
It’s crucial to understand dependencies of core applications when creating your
DR plan. Does an application depend on an external database on another VM?
What restore order is needed to test the application? And even today, we still
need to be concerned about what servers are still physical. These dependencies
are critical to catalog and plan for. No matter how well you protect the critical
VMs, if you forget the weakest link in the dependency chain, you might as well
have not protected any systems.
Active Directory, DNS and DHCP
Everyone has some critical applications that are core to the organization’s success,
and maybe people look to protect these applications first. This is a mistake that
can be avoided but continuing to follow the change of dependencies down the
lowest level. Assuming you have basic physical facilities and network access
accounted for in the DR plan, you need to make sure that core infrastructure
services are next on the plan. Like buying a car without wheels, restoring your
critical applications without these core infrastructure services will have you going
nowhere fast.
Core Infrastructure Services Needed for DR
• IP address assignment (DHCP, etc.)—Local to each site and required for
any communication on the network
• DNS—Ensures that servers and PCs understand how to reach each other
as well as Internet resources
• Active Directory—Provides directory service to secure access to recovered
systems
These services can be provided in a number of ways, but in the majority of small
business and mid-sized companies, we are talking about Microsoft Windows
Server VMs running Active Directory. Before Active Directory servers providing
6
7. VMware Disaster Recovery Planning: Essential Checklist
DHCP and DNS can be recovered, you need to ensure you have a strategy in
place to guarantee their recovery. If Active Directory servers are restored
incorrectly, you will waste precious hours conducting manual recovery steps to
restore function to this critical service. Ensuring a successful trouble-free restore
actually starts with a VM backup and replication tool that fully supports VSS
(Volume Shadow Copy Services) for both backups and restore. Veeam Backup
Replication has provided this functionality since its first release. This VSS-aware
technology is the key layer of defense for situations in which you are unable to
replicate Active Directory to your disaster recovery facility. Example scenarios
include single site businesses without the budget for a DR site, or businesses
that choose to only maintain DR contracts with cloud providers and don’t want
to maintain active VMs that incur monthly fees.
Mission Critical Applications
Mission critical applications are the lifeblood of the company and consist of
stateless application server VMs as well as VMs containing persistent data like
databases or file system objects. With traditional legacy backups this can be
a terrible chore to document and remain current on all the specific files and
folders inside a VM that needs to be backed up, especially when application
upgrades may create new files and folders not included in the original backup
configuration. Focusing on entire VMs for a virtualized DR plan avoids focus
on the micro-management of the data protection, but rather on identifying the
higher level service components that need to be protected and restored.
Similar to the Active Directory backups mentioned earlier, if your mission critical
database is running SQL Server, you need to leverage VSS-aware products to
ensure application consistency is maintained during backup and replication.
Without this key technology, you will be left with crash-consistent databases
which will slow your recovery time after a disaster or during disaster exercises.
Microsoft SQL Server provides what’s called a VSS writer with its products, and
is one of the key pieces that Veeam can leverage with its own advanced VSS
requestor technology to ensure application-consistent backups. However, if you
are not running a database or OS that supports VSS you will have to take other
precautions. In the non-windows world, there can be various ways to ensure
database and application consistency during backup and replication windows.
You will need to identify these non-VSS enabled Databases and work with good
database administrators (DBAs) that understand the application requirements so
you can create a backup and replication method that can guarantee application
consistency. This may require pre- and post-scripts to be developed, purchased
or borrowed from the community or a vendor. These scripts can help guarantee
recovery consistency by shutting down the database service and freezing I/O on
the mission critical VM until Veeam can initiate the VM snapshot.
Stateless Application Servers
Not all servers contain persistent data, but all servers have a rebuild time. This can
be as simple as an automated deployment or a large effort involving significant
time and labor costs. These stateless application servers can be important servers
to protect, but they will not be protected in the same way as busier servers
with critical business data being creating daily. These servers can be protected
less frequently and triggered only during critical periods containing change. For
instance, prior to application upgrades or major software changes, you could
initiate a whole-VM backup and take small, quick incremental backups for a
7
8. VMware Disaster Recovery Planning: Essential Checklist
period of time to ensure you have a good known state to restore to. Then shortly
after the software change has been determined to be successful, you would
then want to take another series of full and incremental backups to provide a
good known state of the VM to restore back to if disaster occurs after the VM
change. Once you have proven you have good backups of these stateless VMs,
the schedule can be relaxed to save bandwidth and I/O. As long as you continue
to test restores of the entire application stack, along with its dependent data tier,
this can be an option for certain DR requirements.
Protect Your Deployment Systems
Some businesses choose to invest heavily into their ability to quickly re-install
application stacks on stateless VMs rather then protecting more data than is
technically needed. This can be a great strategy for scale-out workloads like
Terminal Server-based application servers, java application or web servers. In
these situations there is a large ROI (return on investment) from automating
the provisioning of complex server configurations and utilizing it often for
upgrades, server refreshes or scale out operations. This doesn’t mean you’re
off the hook, though. You'll need to follow the dependencies and identify the
systems responsible for re-deploying these stateless VMs to make sure that
they are protected and available in the DR site. This exercise will raise some
interesting questions about what should and should not be re-deployed as
part of a disaster, ultimately bringing into the question of the value of end-to-
end provisioning systems. In short, end-to-end provisioning strategies should
also include re-deployed tested whole-VM images as well as whole application
stacks. Your ultimate decision will just come down to numbers—how many VMs
are based on a common configuration and how quickly they need to be restored
in the event of the disaster.
Automate VMware Environment Data
Collection
VM inventory automation can help quickly and accurately collect information
on the virtual environment that’s invaluable to designing your DR plan. Whether
you have 25 VMs or 2,500, automating the collection of VM information can
jumpstart you on the way to accurately designing your DR plan. There are a
multitude of tools available to assist with this data collection task. Since we’re
planning for a virtualized DR plan, I’m a big fan of leveraging virtualization
management software from Veeam to help ease this task.
Veeam Reporter
Veeam Reporter is a great tool that gives you the insight into your environment
very quickly. There is both a free version and full version of Veeam Reporter.
Both can be invaluable in quickly collecting inventory information from existing
VMware environments. This information helps document your primary virtual
datacenter, and can be a guide for setting up the disaster recovery site. Output
from this tool include spreadsheets, Word documents and even Visio diagrams
of your VMs, ESX(i) hosts, VMware datastores and networks. Veeam Reporter can
grab a lot of data in just a few minutes.
8
9. VMware Disaster Recovery Planning: Essential Checklist
Veeam Monitor
Whether you are looking to build out the bare minimum DR infrastructure or you
are looking to determine at what point your DR solution is just getting gaudy,
you'll need good statistics on current resource utilization to properly size your
DR infrastructure. Veeam Monitor can be used to assist you with this resource
utilization collection. Again, there is a free version, but the full version is the
way to go if you would like to continue charting virtual infrastructure utilization
after the planning phase. When measuring virtual infrastructure utilization, we
are trying to capture a few key areas that will determine the ultimate cost of the
solution. CPU and memory utilization is important for sizing the servers required
for the recovery site. Here we’ll focus on CPU GHz used on average, and GB
memory consumed.
Storage Consumption with Veeam Backup Replication
Storage requirements can be complex to discover. Although Veeam Monitor can
report on how much storage you are using today, it’s not operationally realized
for a virtualized DR plan. This means it doesn’t give you an easy way to estimate
your storage requirements for backup and replication of whole VMs. To accurately
assess storage needs you should consider using Veeam Backup Replication
and conduct an actual proof-of-concept (POC) of the software. This will allow
you to learn how the product will work in your environment but also to give you
real-world values for backup storage needs. Everyone can determine the cost to
store full backups since it is just a multiplier of the original disk, but incremental
replication passes can be tricky. By running Veeam Backup Replication for a
few days on actual workloads, you’ll accurately record the real-world values for
the daily change rate as well as gain statistics required to size your DR storage
systems. This daily change rate of the VM data will be critical in determining
future replication bandwidth requirements as well. So, with a simple POC of your
possible DR solution, you’ll be able to gather the statistics needed to properly
size two of your most expensive DR resources: storage and network bandwidth.

10. VMware Disaster Recovery Planning: Essential Checklist
Virtualize the Stragglers
If you still have physical servers, it’s time to make the switch. The benefits of
virtualized DR are well known and have been written about and practiced for
more than 5 years. No matter how good your DR solution for physical servers is,
it can’t come close to approaching the capabilities and cost of a virtualized DR.
But many workloads have avoided migrating to virtual for one reason or another,
which throws a wrench in to the DR planning machinery.
VMware Is Best DR Platform for Business Critical Workloads
You probably have a large portion of your environment virtualized with VMware,
but it’s likely that you have some business critical systems that remain on physical
systems because of their importance. Unfortunately, placing your business
critical systems on physical servers because they’re important is a mistake. If they
were that critical to your business, don’t you think that providing the ultimate
DR solution for them would be your organization’s starting point? These critical
systems should be virtualized to experience the full benefits of virtualized DR,
but not every application owner and DBA fully understands our virtualized DR
zealotry. You'll need to communicate the benefits inherent to today’s virtualized
DR to these application owners to win them over.
Virtualized DR Benefits
• Snapshots—Be able to test critical patches and roll back if failure
occurs
• Restore entire server image (operating system [OS], application, data)
to any hardware without messing with drivers
• Refresh hardware with zero downtime
• Restores can be automated and tested often
• Files and other application items can be restored from VM backup
images
• VSS integration can ensure application consistency
VMs Performance Is No Longer a Barrier
Stubborn DBAs and critical-application owners may love to take you up on
DR capabilities alone, but they still have one trump card in their hand: VM
performance concerns. Five years ago, they might be justified in playing that
trump card. But with advances in virtualization software and hardware purposely
built for virtualization, these concerns are no longer warranted.
• VMs can now scale up to 8 processors with 255 GB of RAM
• VMs are capable of providing north of 300,000 IOPS when configured with
a powerful enough backend storage system
• 10 GB networking erases concerns of VMs being starved of bandwidth by
other VMs
• Next vSphere version due out in 2011 will likely increase these limits more
Yes, VMs can scale larger than ever before, but without proper VMware capacity
planning practices, the benefits are negated. Planners still need to ensure they
10
11. VMware Disaster Recovery Planning: Essential Checklist
have the right consolidation ratios given the virtualized workloads and underlying
hardware resources. Having the tools to properly plan these consolidation
ratios, monitor utilization and give application owners relevant virtual hardware
performance statistics is critical. Tools like Veeam Monitor can provide the
performance view at the hypervisor level and provide OS level statistics in a
single view. Having the right plan and the right visibility into performance will
help gain trust and drive more use of virtualization where you need it most.
The Singular Option: 1 VM Per Server
All the management tools and virtualization know-how may still not be enough
gain permission to virtualize critical servers. Many times these mission critical
workloads have seen duty on non-x86 server platforms in the past, such as an
AS/400 or a proprietary RISC-based platform. These options were not cheap and
many times more expensive than a physical x86 server, so they are not easily
defeated by server consolidation benefits. With today’s powerful virtualization
enabled hardware and VMware software to provide the DR platform, you have a
singular option available to meet the performance and DR requirements of the
critical workload. That means dedicating a single host server to a critical VM.
Who says just because you are running VMware on your servers that you have
to maintain hero consolidation ratios? Putting performance (and egos) first and
not being afraid to consider limited use of 1:1 consolidation ratios, will help you
win over the stodgiest application owner. Over time, you may be able to win their
trust to allow higher consolidation ratios as long as performance requirements
are met. The singular option is a little of both, but when compared to the lack of
DR features for physical servers or the cost of the proprietary past, it can make
good sense.
On-Demand Sandbox Testing
Once virtualized, another unique benefit you can offer owners of business critical
applications is the ability to troubleshoot on mirror image systems in real time
without disrupting the production server image. How is this possible? Veeam
Backup Replication offers an On-Demand Sandbox functionality. . This sandbox
functionality allows you to boot VMs directly from an NFS server presented by the
Veeam backup host, without requiring a time-consuming restore or provisioning
extra storage to the vSphere environment. This capability allows problems to
quickly be resolved since administrators will have exact copies of productions
systems to test with, restart services or try fixes without the fear of disrupting
operations on the live systems. This enables the system administrator's version
of the Hippocratic Oath so administrators “do no harm” to production systems in
the process of fixing them. This is no replacement for good system deployment
capabilities, but there are plenty of instances where, due to the number of systems
deployed, it doesn’t make sense to spend time automating the deployment. In
this case, having the entire VM backed up for redeployment is a big benefit for
developers.
Analyze Resource Requirements
It should go without saying, but DR planning is about preparing for the loss of
your primary datacenter. This means you need to size and budget for a recovery
site capable of meeting your requirements in a disaster scenario. During the
assessment phase of our DR planning, automating the collection of some
11
12. VMware Disaster Recovery Planning: Essential Checklist
key virtual infrastructure inventory as well as resource utilization statistics is
recommended. It’s now time to use that information to properly size your DR
solution.
Compute
It's best to start with compute statistics, that is, how much CPU and memory are
utilized. If you're planning to restore every single server and maintain identical
capacity, this exercise is easy and you'll duplicate your production environment
at the DR facility. In more budget-minded organizations, you're going to analyze
the statistics of production workloads and identify only the critical workloads that
need to be running in order to establish the estimated DR infrastructure required
in a disaster. These utilization statistics translate into CPU sockets required.
Storage
When analyzing the storage requirements, we want to make sure that we
have enough raw storage space to store what is necessary. But we also want
to know what kind of performance characteristics are required to drive your
primary workloads. For storage space requirements you will start with the total
gigabytes of all the VMs that you plan to recover to the DR site. Add to that,
the amount of full backups or replicas you'll want to keep and the amount of
daily incremental backups. Generally speaking, DR storage is based on the VM's
configured memory and storage allocation, so calculations could be derived
from the statistics gathered with Veeam Reporter.
In addition to the raw space, it's important to understand the performance
required of your storage systems. This is usually measured as IOPS and storage
bandwidth. These two statistics describe how active your VM storage is, and
whether you can get by with SATA drives, SAS drives, or whether you'd be a good
candidate for an auto-tiered storage system with enterprise flash or SSDs for tier
0, SAS for tier 1 and SATA for tier 2. Many people make the mistake of buying
large capacity SATA for DR because they can save on storage purchase costs.
However, when it comes time to rely on that storage in a disaster, the availability
of their systems is in jeopardy due to performance. It's understandable to want
to save money on your DR, but for this size of an investment, you need to make
sure you're not shooting yourself in the foot by getting too risky. Analyze the
statistics and budget accordingly.
Network
We talked about calculating daily change rate of data earlier. If you decide to
use replication over a secured VPN connection over the Internet or leased WAN
circuit, you'll want to know how much data will need to be moved across the
network in a single day or replication window. This will help you forecast the size
of Internet bandwidth required to be successful and if you need to upgrade your
WAN circuits. If your options for Internet bandwidth are limited, this analysis will
be crucial to understand whether you will be a good candidate for replication or
whether whole-VM backups to tape-backed disk archives is a better option for
you.
WAN Acceleration Need
In analyzing your network connectivity, it's critical that you understand your
bandwidth, the latency between your primary site and DR site, and the reliability
12
13. VMware Disaster Recovery Planning: Essential Checklist
of the connection. If you have high latency and packet loss connections, you
may not be able to meet your backup windows, and consequently, suffer lower
RPOs. Products like HyperIP from Netex offer WAN acceleration technology that
is purpose-built for accelerating large data transfers over packet loss and high
latency network links. If you are a Veeam customer, they even offer a 1-year
free trial version of HyperIP to allow you to thoroughly kick the tires before
purchasing.
Design for Easiest Restore
It is imperative that a good DR plan design for the easiest restore possible. In a
disaster situation, there can be a lot of confusion, different environments, and
possibly a different or missing workforce. A disaster is not the time to have many
complex, manual steps to follow while under the stress knowing your business'
ability to pay your next paycheck may hang in the balance. Simplicity is king in
a disaster situation. You can't count on having your best DR expert available to
coordinate the recovery. You should plan for other personnel to be coordinating
the recovery while you or your DR expert is stuck on a Caribbean island with the
cell phone turned off. Being successful in this situation will require your skeleton
DR staff to have plenty of DR exercises under their belt and have the simplest
restore procedures possible.

Don’t Reinvent the Wheel, Restore the Whole VM
In a VMware DR plan, you want to utilize the most powerful features of VMs:
encapsulation and hardware independence. VMs are just a group of files and
can be copied to other ESX(i) servers (regardless of hardware vendor) and can be
powered on and returned to service, sometimes, without any further modification.
For this reason, whole-VM protection methods are superior to legacy methods
that rely on multiple manual steps to create a workload from start to finish. From
the comparison chart below it's pretty easy to see why whole-VM recovery is
preferred.
13
14. VMware Disaster Recovery Planning: Essential Checklist
Using legacy protection measures on virtualized workloads introduces complexity,
cost and risk to into your DR plan that your company can’t afford. By restoring
the whole VM you drastically cut the number of steps required and you open
the door to be able to test and verify the recovery of the VM prior to needing it.
Start with Replication
There are two general methods to accomplish whole-VM recovery: VM backup
and VM replication. The first requires you to backup the entire VM to some
external storage media or a replicated file system. Then when recovery is required,
restore the VM to the recovery site ESX(i) servers through a simple file copy.
Veeam Backup can make this process slightly quicker in that it offers instant-on
features allowing you to present an NFS export to the ESX(i) server, and boot a
VM directly from its backup file. Eventually you would need to perform a Storage
vMotion of the VM to primary storage or do a full cold restore of the VM from a
backup media/file system to the recovery VMware environment.
The other recovery method is to replicate the entire VM to the recovery site
ESX(i) servers so that the replica VM is already pre-staged and ready-to-boot. To
recover the VM, you power it on. As simple as VM backup is, one-step recovery
with VM replication is very hard to beat and it is almost impossible to provide
better RTO unless you call active-active geo clustering a recovery technique.”
When designing for easiest restore, VM replication has to be on the top of your
list for tools to consider.
Decide on Infrastructure Configuration
After all the interviews, data collection and analysis, you'll eventually have to chart
a direction and make some decisions. You'll have to decide on a final configuration
for hardware, software, off-site data transport method, and recovery processes.
There is no one right way to do this but armed with business requirements for
recovery, application dependencies, and your budget guidelines, you should
have enough information to start to make some decisions
Servers
Any x86 server hardware will do here, but the question is more about what
kind of capacity do you require in a disaster and what's the most cost effective
way to meet that need at the DR site? Those 5-year-old 2U rackmount servers
with 4 total processor cores and 16GB of RAM might do okay in a pinch for a
small portion of your DR environment, but only if you don't recover the whole
environment. Although those servers might be free, they don't look so good when
you're paying for rack space and power for dozens of servers at a co-location
facility. It may be cost advantageous to purchase new servers that have 10 times
the capacity which can reduce DR licensing costs for Veeam and VMware while
cutting your physical space and power requirements by a factor of 10. Whatever
your decision, make sure you provide for adequate capacity based on real world
measurements from your production VMware environment and guided by the
Business Impact Assessment (BIA).
Storage
If you need vMotion and High Availability at the DR site, you'll need to invest in
shared storage to go with the VMware ESX(i) servers that you'll be replicating to
or restoring VM backups to. Choosing NAS, iSCSI and Fiber Channel are all good
14
15. VMware Disaster Recovery Planning: Essential Checklist
decisions, and most are valid options. If you are a small business or a small remote
office, shared storage for VMware may not always be possible and you may be
required to use local storage contained within the recovery servers. Although
these setups aren't as efficient to manage in a production environment, they can
be good enough in a disaster to allow your business to provide revolutionary
DR capability at a bargain price. In configurations with locally attached storage,
you'll be happy to know that Veeam Backup Replication can support that
option as well since it can write to any VMware datastore visible to ESX(i) server.
Network
We talked earlier about network considerations. Basically, there is enough
network bandwidth or there is not. There either is high latency or there is not. If
you have the budget, make the investment in high bandwidth links between your
recovery site and your primary datacenter. This can allow the most reliability and
lowest operational cost for your backups and replication since no error-prone
manual or physical methods are required to me move data to recovery site.
Whether it is due to budget-related or geography-related limitations, not
everyone has the network bandwidth available to replicate critical assets. That's
why the old adage remains true, Never underestimate the bandwidth of a van
full of tapes driving down the highway. Your network realities may dictate a
whole VM backup to disk or tape that is then trucked off-site for safe keeping or
for test restoration at the DR site. In these situations you will be sacrificing the
ultimate RTO from the start, so it's not as important to have all servers racked,
stacked, powered and ready to go. You might even consider alternate means for
provisioning server resources in these scenarios.
DR in the Cloud?
In the case where replication is not an option and you have VM backup images
that can be restored to any ESX(i) servers in the world, why not restore to the
cloud? There are countless VMware hosting providers available today that can
rent you resource pools or whole VMware environments. Rather than investing
in expensive, duplicate datacenter locations that will only be used in the unlikely
event that an actual disaster occurs, you can instead bank that money and only
pay a small portion in the event a disaster happens or in the event you'd like to
test your recovery. If you do decide to move forward with restoring to a VMware
hosting provider, you may need to do some advance planning on the contract
side to help speed your recovery if needed. Although we're getting closer to the
dream world that allows you to whip out the company credit card and spin up a
DR site in minutes, it's more likely that you'll want to sign a contract in advance
in order to get some guarantee that the resources you'll require will be available
should you declare a disaster. Of course this insurance will cost you, but it will be
much less than if you purchased the resources full time or if you stood up your
own DR site.
Test-Driven DR Plan
In the software development world, a popular software development process is
test-driven development (TDD). In TDD, developers first create automated unit
tests that will only pass successfully if the new piece of code under development
fulfills all criteria. By writing the test first and then developing the code, quality is
15
16. VMware Disaster Recovery Planning: Essential Checklist
improved since code can’t be released until the unit tests pass successfully. This
process has proven very successful for software developers, and a derivation of
the process can now be applied to virtualized DR. This derivation can be called
test-driven DR and it turns traditional DR planning on its head by planning for
the restore and verification of the restore before you plan to do your first backup.
Design with Testing in Mind
It takes more than petabytes of shiny deduplicated, compressed backups to save
the day in a disaster situation. If you can't restore successfully and quickly from
those fancy backups, then what was the point? With today's VMware virtualized
systems, there is no longer an excuse to not test your recovery as often as
possible. If replica VMs are ready to boot in a test recovery environment, you are
just a PowerCLI script or web service call away from creating custom workflows
to orchestrate the recovery of your protected VMs. By building upon what you
learned with application dependencies and target RTOs, you can create custom
workflows that will bring up your protected VMs in the order required to test
your ability to restore. And since we're talking about virtualized environments,
you can easily adjust the VMware networking with a simple web service call to
ensure that recovered VMs are placed in an isolated network that you prepared
in advance. Your functionality is only limited by your time and scripting ability.
However, not everyone is a programmer or has the time to create these workflows
and verification scripts. Veeam SureBackup is the solution to help programmers
and non-programmers create a foundation for their test-driven DR plan.
SureBackup Recovery Verification Is Test-Driven DR
With the SureBackup functionality in Veeam Backup Replication, you can verify
the recoverability of every VM backup every time. This recovery verification of
individual VMs is the essence of test-driven DR planning since you are designing
tests that will fail until you properly design and execute your automated backup
and restore system properly. As in TDD, if a SureBackup verification test fails, you
will reconfigure your recovery or backup until the verification passes all tests.
Since it’s all virtual and able to automatically run within an isolated network, you
can run these DR tests repeatedly until you find the hidden dependency, incorrect
IP addressing, or out-of-order recovery step. This cycle of DR plan refinement can
verify your entire DR plan within a few short days for small DR plans to weeks for
more complex DR plans.
Test-Driven DR Enables Continuous Testing
With traditional DR exercises leveraging legacy DR solutions, businesses are lucky
if they have the time and budget to test their DR plan annually, let alone resolve
all outstanding issues with the recovery. The technology is available to make
test-driven DR planning a continuous process for your virtualized environment.
You should work toward a goal of near-daily automated recovery verifications
to bulletproof your DR plan. Limiting yourself to annual or quarterly DR tests is
a relic of DR planning past that no longer applies. When creating your VMware
DR plan, be sure to not only eliminate legacy technologies of the past, but to
scrap the legacy processes as well. Freeing your mind of yesterday’s DR baggage
will help you embrace the possibilities of virtualized DR and fully experience its
benefits for your business.

19. VMware Disaster Recovery Planning Essential Checklist
DR planning in a VMware environment requires old-fashioned DR planning fundamentals but also requires
fully leveraging virtualization’s unique characteristics. This checklist of 10 proven DR planning activities
provides you a jumpstart towards an award-winning VMware DR plan.
Conduct a Business Impact Analysis (BIA).
A BIA helps you identify critical business systems, their IT and human dependencies, and an estimated
disruption impact to your business. You can then determine which applications are most important.
Know your recovery point objective (RPO) and your recovery time objective (RTO).
Develop an intimate understanding of how your business runs and catalog the key resources and processes
necessary to enable revenue creation. Translating the findings from the BIA into RTO/RPO requirements for
each application, helps you focus your resources where they are needed most.
Understand your budget.
Virtualized DR is much less expensive than traditional physical DR, but it is still an additional cost on top
of your already sizable investment in virtualization software, supported server hardware and new storage
systems. Avoid the expense of maintaining both legacy and virtualization-aware backup systems by migrating
to all virtual DR.
Understand application dependencies.
Most applications have dependencies external to the virtual machine (VM) that it runs on. In a disaster, it’s
critical to have cataloged these dependencies because you will have to recover each one to restore end-
to-end functioning for that application. Start at the base infrastructure services like DHCP, DNS and Active
Directory. But don’t forget to account for file shares, databases or other non-virtualized servers recovered
through legacy means.
Automate VMware environment data collection.
VMware inventory automation can quickly and accurately collect information on the virtual environment
that’s invaluable to designing your DR plan. Tools from Veeam can help ease the task. Veeam Reporter can
catalog the configuration of the VMware environment, even providing Visio diagrams to reference. Veeam
Monitor can provide the performance statistics you need to size your DR infrastructure. Plus, a Veeam Backup
Replication proof of concept (POC) is a good way to learn what your daily data change rate is so you can
appropriately size your network connections to the recovery location.
Virtualize stragglers.
If you still have physical servers, it’s time to make the switch. The benefits of virtualized DR are well known
and have been written about and practiced for more than 5 years. No matter how good your DR solution
for physical servers is, it can’t come close to the capabilities and efficiencies of virtualized DR. Virtualize your
remaining physical servers to achieve the most benefit from your DR Plan.
Analyze resource requirements.
Using the data collected in the assessment phase of your DR plan is invaluable in sizing the DR site and
creating your DR budget for servers and storage. The largest limiting factor to the ideal DR plan for VMware
is the bandwidth required to replicate all necessary VMs. Consider products, such as HyperIP from Netex,
that offer WAN acceleration technology purpose-built for accelerating large data transfers over high packet
loss and high-latency network links. This can allow for better use of available bandwidth without breaking
your budget.
Design for easiest restore.
Simplicity is king in a DR situation. Rather than reinvent the wheel by reinstalling operating systems,
applications and restoring individual files, you should restore the entire application as a VM to minimize
restore time. Replicating the VM with Veeam Backup Replication can provide the lowest RTO possible since
VMs only need to be powered on to restore service.
Decide on infrastructure configuration.
In today’s cost-conscious IT environment, it’s good to know there are options for your recovery site
configuration. Although you can choose to self-host DR options in your own facilities, you can also take
advantage of VMware service providers that could provide your DR infrastructure as an on-demand cloud
service.
Test-drive your DR plan.
Setting up a DR plan for VMware environments is not a one time activity. You need to ensure that you
test, test and test. Manual tests are good, but since you’re working with VMware technology, there’s no
reason testing can’t be automated and run as often as daily if needed. Using Veeam Backup Replication’s
SureBackup automated backup verification feature is a great way to do this.
