Easy Disaster Recovery TieringThe IT Hero’s Guide to Tiering 911 Call Center Applications Reduce costs and improve resilience for your Disaster Recovery plan

The Super Simple Basics: Smart Tiering is cost-effective and easy to implement
If you are like most IT professionals, you know what application tiering means, but have
probably not defined things like RTO (Recovery Time Objective) / RPO (Recovery Point
Objective) / Tiers, or do not have agreement on definitions with your dispatch center
leaders. You may think doing so requires a six figure project with a big five consulting
firm and are trying to make do without getting too far into specifying a viable tiered DR
(Disaster Recovery) architecture.
In fact, that level of effort is not required, and not developing a tiered DR solution is
actually more expensive than putting one together. Especially in a 911 call center where
the stakes are high.
Tiering is valuable for everyone, not just for large enterprises and global corporations.
Any organization can use the same basic approach and best practices – if they have the
right partner – without needing a huge team of people and a six figure budget.
Public safety agencies of any size can implement a solid, multi-tier BCDR (Business
Continuity and Disaster Recovery) architecture. Doing so reduces their one-time and
ongoing costs and improves the overall resiliency of their systems at the same time.

Keep It SimpleTiering is all about figuring out how long your 911 call center systems and services can
afford to go without having access to the applications users depend on to protect and
serve. The reality is your operation uses some mission critical applications, like CAD, all
day, every day. There are others however, that you only need from time to time.
While it’s technically feasible to use the same level of protection for every application, it’s
not cost-effective and often means under-protecting more critical applications. The trick
is dividing your applications into four groups, or tiers, and then implementing the right
amount of protection for each tier.
The bottom line is that making smart choices in setting up your tiers can save money
while improving the ability of your dispatch operations to withstand any type of outage or
disaster.

We’ve worked with thousands of 911 call centers to help them devise the best disaster
recovery and business continuity strategies for their operations. Time after time, we’ve
seen that the key element in developing a successful strategy is super simple:
• Get the right people in one room and spend a few hours on a whiteboard asking the
right questions.
• Keep your team small — find people who understand how the applications they use
affect overall operations. This is often the managers for each department, but your
agency might be different. The key point is to find a time when you can bring the right
people together for a discussion.
• Use a whiteboard to write down all applications that your processes and services
depend on to operate. As a group, decide how long the system can continue
operating without each application. (For example, the records management system
might be able to be unavailable for a few hours without harming operations, while a
CAD system has to be up and working all the time.) Remember, these decisions are
not really about data protection – any good disaster recovery system will protect your
data. These decisions are about ensuring things like emergency response and call
dispatch.
You want to spend as little as possible in order to protect everything to the appropriate
level. The team’s job is figure out what that level is for each application.

Then do some simple triage. Mark each application as belonging to one of these three
groups, or tiers:
1. Those you can’t live without for more than 1-2 hours
2. Those you can’t live without for more than 4 hours
3. Those you can’t live without for more than half a day
4. Those you can live without for a longer time if you can be certain the data is safe
Protecting applications in the last 2 groups is the least expensive, so the group members
should bargain with each other a bit to try and put as many applications into these
groups as possible.
That’s it! You don’t need an outside consultant to do this for you, and you should be able
to complete the process in a couple of hours. At the end of this exercise, you will have
defined application tiers that ensure you do not overspend or under protect again, and
agency-made agreement and buy in (which makes the funding process easier).
The next step is to have your IT team work with your DR/BC vendor to select the best
solutions and implement the plan. When selecting the appropriate solutions for each tier
of application, you must start by understanding all of the different stages that make up
an outage, and why many of the “15 minute failover” promises you are bombarded with
every week are not the answer. If you haven’t read our “Anatomy of an Outage” eGuide
yet, you can learn all of that and more here.

NEWCOM is here to help You can access NEWCOM’s many years of experience to make this process even better.
Our team of experts has seen it all. They will work alongside your team to help you avoid
under protecting your operations or overpaying.
Don’t worry – we don’t charge for this work! If you request our help, we’ll guide you
through a proven, informed decision-making process that will provide quick value to you
and your systems and services. Together, we can qualify your applications and decide
which level of protection is the best fit.
Whether you’ve developed the basic strategy on your own or with our help, we’ll work
with you to refine it and turn your decisions into practical next steps. We’ll help you
assemble a budget and a timeline for the whole project. More importantly, we will make
sure your agency is always protected at the appropriate levels and you are a hero!
Now let’s look at each tier in more detail.
These are the lowest tiers and are for your non-critical systems. A simple
test: Are you more concerned about protecting the data or making sure the
application never goes down? Nearly every public safety agency has several
systems that they can afford to live without for a day or more.
For example, your internal HR system is important, but if you weren’t able to
access it for a little while, it doesn’t mean you have to shut down.
Basically, your focus on Tier 3 and 4 systems is on protecting the data itself. In
technical terms, we would say that your RPO is a lot more important than your
RTO.
For Tier 3 and 4 systems, NEWCOM recommends a comprehensive backup
and recovery system that will protect critical data, no matter what happens to
your call centers or your computers. But – and this is an important but – you
won’t spend a dollar more than you have to in order to achieve that. Tiers 3
and 4 are your least expensive options and you’ll want to use that for as many
systems as possible.
Keep in mind, though, that it may take several hours – as long as working day -
to bring systems protected at the Tier 3 or 4 level back up.
Tier 3-4 The least expensive protection for your data-centric applications

Tier 3: Backup for data-centric applications
Data-centric backup solutions utilizing a second location (yours or
a CJIS certified cloud provider for example) is generally sufficient
for Tier 3 applications. NEWCOM recommends Veeam Backup
& Replication for this tier, back ended by a Neverfail HybriStor
appliance – market leading deduplication and compression
technology that is a Veeam Ready certified storage repository.
It’s perfect for applications that are not that critical to your operation,
but that you need to be able to access fairly quickly — within less
than a day or two — in the event of a disaster or major outage. The
Veeam solution allows flexibility in meeting these demands, as well
as any retention requirements for compliance or otherwise, and
HybriStor ensures scale and speed of recovery with an average
of 8-10X less data needing to be stored on disk and the ability
to instantly restore without going through a lengthy rehydration
process.
Tier 4: Archive for long term data storage
Think of Tier 4 as cold storage. This is the least expensive way to
protect archival data that you might not ever need to access again.
For example, you may want to protect compliance-based retention
data from years ago with Tier 4. If, for any reason, you do need to
get at those old records, the data will always be available and you’ll
be spending as little as possible to ensure that.
What’s the Difference Between Tier 3 and Tier 4?In terms of the white board exercise described above, it’s useful to
group applications that will ultimately be assigned to Tier 3 and Tier
4 in the same “bucket”. The functional differences between these
tiers are fairly minor, and, by putting your less important applications
into the same group, your decision-making process will be less time-
consuming for everyone involved.
Once you have decided which applications will go into this group,
your IT people can work with NEWCOM engineering team to develop
a detailed implementation plan, including final decisions on which
applications will utilize Tier 3 or Tier 4 level protection.
This intermediate tier is for the systems that are important to keep up and
running with as little downtime as possible, but that are not mission-critical
and do not require the same level of investment. For example, records
management is important to most dispatch centers, but many centers can live
without it for a few hours.
Systems protected at the Tier 2 level should be back up and running in two to
four hours or less. There are several ways you can configure Tier 2 protection.
For example, in order to keep costs as low as possible, you may look to a
cloud-based protection strategy that utilizes a smaller standby resource pool
– you may not need servers on standby with exactly the same specs as your
production systems. In this case, you can bring your systems back online
using the least expensive standby resources that will support your needs.
Your people will get access to the Tier 2 systems and be working productively
again quickly. This gives you as much time as you need to take care of fixing
or replacing your production systems, which you can then switch over to as
soon as they’re ready.
Think of Tier 2 as a happy medium, or “just right” protection for many of
your most commonly used systems. In fact, 50% or more of your applications
may be perfectly fine with a smart combination of Tier 2 and Tier 3 and 4
protection.
Tier 2Goldilocks protection for important applications
Tier 1 is for applications that you can tolerate having down for 1-2 hours, but
will have significant negative impact on your operations if they are out of
commission for too long.
Tier 1 is application-aware, which means your Tier 1 applications should
be monitored and issues should first be corrected when possible. To keep
costs as low as possible for Tier 1, we don’t recommend keeping a fully
duplicated set of computing resources running for you on hot stand-by, but the
application awareness and monitoring against downtime events is critical to
public safety.
However, you can manually add more resources to the failover systems as
needed in order to utilize them effectively during an outage. When the outage
is over and your production environment is back up and running, you can turn
down the failover site’s resources again to a minimal level so you’re prepared
for the next outage.
Tier 1 does require some manual intervention to optimize the failover servers
for production use, and that is one of the factors that keeps Tier 1 costs
affordable. But, this tier is often the right fit on systems like jail management.
Tier 1 High Availability for critical applications
Tier 0 offers the highest level of protection and is intended for applications
that are truly mission critical; that is, you can’t afford for them to ever go down.
For example, if you are a 911 call center, you can’t afford to ever have your call
dispatch systems stop working.
Neverfail has developed a set of highly specialized solutions that can
absolutely ensure that an application is always online, no matter what. If
there’s a major hurricane, earthquake, or fire that destroys your buildings and
all your servers, a Tier 0-protected system can still stay up and accessible – all
your people will need is an internet connection and a computer.
Essentially, with Tier 0 protection, warm standbys are kept running all the time,
in lock step with their production counterparts. These solutions are hardware,
virtual platform, storage, and location agnostic. If something happens to your
facilities, your applications fail over to another server, or even another location,
to ensure your users can continue to work as normal and your services
continue. This approach bypasses recovery altogether by ensuring continuity.
Of course, Tier 0 is a more expensive protection option and you should only
use it for applications that you can’t afford to ever lose access to. Again, most
organizations don’t need Tier 0 protection for many of their applications, but
for those that do, Neverfail has you covered.
