Introduction
How to Evaluate the ROI of Your Data Protection Infrastructure
| 2
In today’s economic climate, information technology (IT) budgets are under severe pressure, while ironically service level requirements are on the increase. Explosive data growth
is stressing many legacy IT processes to the breaking point, driving IT managers to look for
new and innovative ways to address the challenges that are arising.
Storage is one of the areas hardest hit by explosive data growth. As both primary and secondary storage requirements increase, driven by not only explosive data growth but also by
business and regulatory mandates driving much longer retention periods for archival storage,
the past method of just throwing storage capacity at the problem is becoming increasingly
untenable. And it’s not just budget pressures that are making this approach problematic; the
sheer volume of data, approaching tens and even hundreds of terabytes for many companies in the near future, are leading to skyrocketing storage costs and making legacy approaches and architectures obsolete.
In storage, ensuring that data is recoverable has always been a strong focus. But from a
business point of view, the compelling value that computing infrastructures deliver is based
around application services. While recovering data is a critical part of that, data in and of
itself has little value to the business if it is not accurate and accessible. Recovery plans must
take that into account, delivering a multi-faceted capability that supports the recovery of
application services, ensures that the underlying data is accurate and up to date, and meets
the recovery performance metrics required by the business. These recovery plans must
meet not only local data and application requirements, but also remote recovery requirements so that business operations can be quickly recovered in the wake of catastrophic
disasters that may shut down or destroy an entire data center.
Targeted at a business audience, this white paper will discuss the major cost factors associated with legacy recovery architectures, providing a framework against which the return on
investment (ROI) of newer approaches can be evaluated. Legacy recovery infrastructures
can impose significant costs, many of which are hidden and may not be well understood.
The paper concludes with a short discussion of how next generation data protection technologies address these shortcomings and can result in recovery solutions that have a significantly lower overall cost of ownership and ROI than legacy approaches.
Baseline Recovery Capabilities
As you begin the ROI evaluation process, it is important to understand what application environments and recovery metrics
are most important to you. Without a defined set of needs, put
into place with a good understanding of how recovery needs
to operate for you, it will be hard to accurately evaluate the ROI
of any given solution. The set of common recovery metrics,
which is generally applicable to all open systems servers, operating systems, storage, storage architectures, and applications,
used to evaluate capabilities draws from the following list:
•Impacts of data protection operations on business
processes. These impacts can range from the performance degradation of production applications that can
affect business operations to an outright shutdown of application services directly supporting business processes
for periods of time.
•Data loss on recovery. Often referred to with the acronym RPO (which stands for recovery point objective), this
metric limits how much data you expect to lose for the average recovery operation. An RPO target of 1 hour means
that you have a recovery capability that will limit any data
loss on recovery to no more than the most recent 1 hour
of changes. If data is not recoverable, then in certain
cases it can be re-created by referring to paper records, a
process that is very manually intensive and significantly
lengthens recovery times. In some cases, data cannot be

How to Evaluate the ROI of Your Data Protection Infrastructure
re-created, and it is just lost to the business. Depending
on the business you’re in, this can be a minor annoyance
(e.g. if you’re a small business handling pet boarding and
grooming) or a catastrophic loss (e.g. if you’re running a
trading floor for the New York Stock Exchange).
•Recovery times. Often referred to with the acronym RTO
(which stands for recovery time objective), this metric
defines the maximum amount of time it should take to
recover from an “incident”. An RTO target of 1 hour means
that you can recover in no more than 1 hour from an
incident. Different RTOs may apply to different types of
incidents. An RTO of 1 hour may apply in the case of a few
lost files, while an RTO of 1 day or longer may apply when
an entire site has been lost and application environments
and data must be recovered at a remote facility.
•Recovery reliability. Analyst reports indicate that, when
tape is used as the data recovery media, data cannot be
recovered in up to 20% of the time or more. This is not
necessarily always because a tape drive has failed or a
tape has broken. Tapes may be lost or misplaced, many
recoveries require data to be retrieved from multiple
tapes – all of which may not be available – and sometimes
corrupt data has been written to a tape or a backup job did
not complete as expected, causing the recovery to fail.
Recovery reliability can have a significant impact on both
RPO and RTO as well, since if recovery fails from a certain
recovery point, you must then go back to the next most recent point (which, if you’re using daily backups, can result
in another 24 hours of lost data) and perform the same
lengthy recovery process.
•The extent of manual vs automated processes in
recovery operations. Operations that require human
intervention contain inherent risk, whereas operations that
can be automated can be proven reliable through testing
and incrementally improved or evolved over time. In any
complex manual operation, the skill of the administrator
performing that operation generally becomes a predictor in
the speed and reliability with which that operation can be
completed. When recovery operations can be automated,
they become less dependent on the skill of the administrator and generally become faster and more reliable.
•Cost efficiency. Generally, there are multiple approaches
which can be used to solve any IT problem, each of which
has its own unique pros and cons. Functional capabilities
aside, there may also be significant cost differences between approaches. Budgets can be stretched the farthest
when the lowest cost solution to meet the requirements
is implemented.

Evaluating The Costs of Legacy
Recovery Approaches
The six baseline recovery capabilities will apply regardless
of whether you are evaluating local (i.e. backup-oriented) or
remote (i.e. disaster recovery-oriented) recovery capabilities.
Let’s take a closer look at the hard and soft costs of the major
recovery challenges, discussing each in more detail.
Impacts to Production Operations
When tape backups first were used, application environments
were shut down while backups were performed. When used
for backup purposes, tapes are relatively slow, inefficient
devices, and as most businesses moved to 24x7 operations,
applications could no longer be shut down to perform backups.
Most enterprise applications were enabled for on-line backups,
but on-line backup operations degraded the performance of
production applications, often as much as 20% or more for
write-intensive environments. Performance impacts like this
can impede revenue generation, impact customer service,
and in general slow the overall pace of business that can be
conducted during backup operations. With the worldwide 24x7
operations required by most businesses, there is never a time
that can be chosen for backups that will not have negative
impacts on operations in one or more time zones.
If you’re running on-line backups, do you know how long these
take and what the performance impact is? Given the size of
the data sets for most companies, on-line backups can take
up to several hours or more. In some cases, impacts may not
affect business operations noticeably, while in others there
may be a severe impact. If the impacts are to a non-critical
business process, then the actual cost to the business may
again be negligible, but if they are to a mission-critical application that directly impacts processes like revenue generation
and customer service, then you may want to quantify them.
Be thorough as you consider the impacts so as not to miss
indirect costs that do have a negative, long term effect on the
business. An example of such a process might be any data
collection or business that is being performed using automated
web processes, where a 10% or 20% performance impact
may slow operations to the point where potential customers
become frustrated and do not complete a transaction.
Data Loss On Recovery
While it may be hard to quantify the costs of lost data from
a financial point of view, the frustration that it can entail is
something that has at one time or another impacted us all. If
an employee has just completed 5 hours of work on a particular project, and that data is lost and cannot be recovered,
then that work must be re-done, effectively doubling the cost
of that portion of the project. If the “project” was data entry
WHITE PAPER
How to Evaluate the ROI of Your Data Protection Infrastructure
performed by an underutilized resource, then the additional
cost may be negligible, but suppose that it was a project that
required a very highly paid financial or legal resource, or the
fix to a severity 1 technical support problem that required
architect-level resources for resolution – all of this work must
be re-created, effectively doubling the cost to the company.
In cases like these latter, the data loss generates additional
expense and is a pain, but it can be re-done, but what if the
lost data was 5 hours of financial transactions for a bank,
credit union, or e-commerce site where backing paper records
are not available? The business may re-contact the customer,
requesting that they re-perform the transaction, but regardless
of the response, the loss of data that cannot be recovered
imposes costs on businesses.
Understand how these costs vary with the RPO you have defined for various application environments. If you are performing backups once a day, you can expect on average to lose 12
hours of “work” for every recovery event. How much does it
cost to potentially re-create 12 hours of work? If you implement a recovery technology that drops your RPO to 4 hours,
you have now cut your potential re-work costs by 66%.
Long Recovery Times
The impact of long recovery times can be easier to quantify
than the impact of lost data. Many companies, particularly
those in the financial, e-commerce, and manufacturing areas
where hourly revenue generation and/or production can be
reliably forecasted, know how much they lose per hour when
critical processes are down. To quantify the costs of long
recovery times, you need to know not only your cost per hour
of downtime, but also how many recovery events you expect
each year. If a certain business knows that, for Application
Environment A, if they are down for an hour between peak
operation hours, they lose $10,000 per hour, and they currently
have an RTO of between 4 and 8 hours, then they know that,
on average, they will likely lose around $60,000 for each recovery event. If their past track record indicates they have two
recovery events of this magnitude on average each year, then
it is easy to determine the ROI for an investment that would
drop their RTO to between 1 and 2 hours.
There may be multiple inputs to the cost per hour of downtime. Revenue generation can clearly be one, but what about
the cost of idled human resources during the outage? For an
increasing number of companies, messaging applications like
Microsoft Exchange and Lotus Notes are the way business is
transacted, with the use of telephones a distant second. Have
you ever been at a company where, when informed by IT that
e-mail will be down for the remainder of the day, many employees go home? This is such a commonplace concern that
many companies pay the price and administrative premium of
installing shared-disk availability clustering software to keep
| 4
downtime to under an hour or so in the event of an e-mail outage. An even more indirect, but potentially large cost may be
associated with lost opportunities. Particularly in the financial
and healthcare industries, timing can be everything, and outages can have huge impacts in terms of profit opportunities
and patient care. In healthcare and emergency services, the
impact of outages can in certain cases even extend to life-ordeath circumstances.
Unfortunately, good data concerning the cost for downtime in
various industries is generally not publicly available. Most companies, if they do know this information, do not like to publicize
it. For that reason, it’s difficult for any vendor to build an ROI
story using recovery times, but those companies with a good
understanding of their costs can certainly do this, and quite
easily (as demonstrated above).
Additionally, service level agreement (SLA) commitments,
driven by either business or regulatory mandates, can also
impose costs in certain cases if they are not met. As part of
contractual agreements with certain customers, you may have
committed to meet “do not exceed” recovery times or overall
uptime percentages for services which can result in fees
being imposed or lost revenue if they are not met. Likewise,
in certain regulated industries, having a DR plan is a requirement and non-compliance may lead to fines or even jail time in
certain extreme instances. Because your data is likely growing
at a very rapid rate, recovery plans that you put in place several
years ago may no longer be able to meet SLA commitments to
which you’ve agreed. In order to ensure compliance and avoid
unnecessary costs, a review of these types of contractual
commitments and an understanding of the costs of non-compliance may be in order.
Recovery Reliability
Recovery reliability can affect costs in several ways. First, if
a recovery attempt from one recovery point, for example the
most recent backup, fails, then you must go back to the next
most recent available recovery point. If you’re doing daily backups, this means that, even if you can recover, you are now losing an additional 24 hours of data. You’ve likely already evaluated the costs associated with lost data when determining RPO
requirements, and those will apply here as well. They include
not only the cost to re-create lost data (if that is feasible) but
potentially an inability to re-create the data, and of course the
manual overhead involved with the additional recovery steps
required. Poor recovery reliability impacts RPO as well as RTO.
Even if data can be recovered, in certain cases it may be corrupt, and this imposes additional costs as well. For example,
if you were able to recover from the most recent backup, but
determined that a database table had been backed up in a
corrupted state, you would need to go to the next most recent
backup. Again, if you’re doing daily backups, this will mean
WHITE PAPER
How to Evaluate the ROI of Your Data Protection Infrastructure
an additional 24 hours of data loss for the corrupted data. If
database corruption has occurred, there are additional costs
not related to recovery that must be incurred to diagnose
and resolve the problem, but the data corruption problem is
mentioned here because of its relation to both RPO and RTO
issues. Recovering corrupt data effectively results in the same
outcome as not being able to recover the data at all: you’ll
need to perform another recovery operation from another
backup, leading to more data loss and lengthening recovery
times. Recovery technologies that support very stringent RPO
and RTO requirements can minimize the impacts of recovery
reliability issues, in addition to the advantages they may provide in other areas.
What Are The True Costs Of Tape-Based Recovery
Infrastructure?
Tape-based infrastructures comprise the lion’s share of legacy
recovery approaches (both local and remote), so we’ll focus on
the costs associated with those environments.
With tape-based recovery approaches, tape is used as the media for initial backups and the source for most data recovery,
regardless of whether that recovery is local (backup-oriented)
or remote (DR-oriented). Once a day, data is backed up to tape,
and copies of those backup tapes are retained locally to meet
daily recovery requirements for lost files, database tables, etc.
Copies of some of those tapes (generally, a weekly or monthly
full backup) were periodically shipped to one or more remote
locations where they can potentially be stored for years. This
off-site storage ensures that data is available for recovery
purposes even in the event of catastrophic disasters, such as
floods, earthquakes, or widespread power outages, that may
entirely shut down primary site locations. If business operations needed to be re-started in some location other than the
primary one, the necessary tapes at these remote locations
would be identified, shipped to a new “primary” location,
application environments would be manually rebuilt, the data
would be loaded onto the new servers, and business operations would be brought back on-line.
While tape-based backup operations are often thought to be
inexpensive, this is a misnomer. While the cost of the tape
media, a consumable resource that needs to be regularly
renewed, is quite low on a $/GB basis, there are a lot of other
costs that need to be considered as well. Because many of
these costs are soft or indirect costs, it is often hard to quantify them. If you’re using tape-based recovery infrastructure,
you may be aware that costs are back-loaded and tend to have
more operational (manual involvement) and soft cost (long
backup windows, extensive data loss, lengthy recovery times,
and poor recovery reliability) components. For most installations of this type, costs will be apportioned as follows:
| 5
Tape drive infrastructure. Whether you’re using small tape
cartridge auto loaders or high end robotic tape libraries, drive
acquisition costs may appear low relative to supportable
capacities. Tape’s single biggest advantage is its low $/GB
costs (when its acquisition costs are divided by the amount of
potentially supportable capacity). Because tape is a removable
media, a particular tape drive may be represented as having infinite capacity, assuming that enough tape media is purchased.
Tape media costs. Physical tapes have a finite life, and using
them in activities like backup that generates a lot of start/stop
(i.e. shoe-shining) activity with a tape drive shortens that life.
Tape media acquisition costs can be low, and compression
technologies can lower that by up to 50% in certain cases.
But tape media must be managed; it must be loaded, labeled,
stored, retrieved, and tracked so that, as older tapes reach the
end of their life cycles, they are replaced by newer tapes before
the older tapes can cause undue reliability problems. Some
aspects of tape management can be automated if large robotic
tape libraries are used, but much of the activity is manual.
Tape handling costs. These are the costs incurred due to the
manual involvement, by backup administrators, to load tapes
into tape drives for daily backups, remove and store old tapes,
create tape copies for shipment to off-site locations, and to
manage the life cycle of tape media. For even small companies, these activities can take up to an hour a day or more, assuming they have sophisticated backup administrative resources available. When tapes must be handled in remote office
environments, where sophisticated administrative resources
are not likely to exist, it can be worse than just a manual labor
issue. Unsophisticated resources tasked with handling tapes
at remote locations may not understand the process and can
be lax in following procedures – issues that quite often lead to
misplaced or mistracked tapes and other reliability problems.
And let’s not forget the costs of storing tapes off-site.
Backup window costs. Tape-based infrastructure supports
comparatively low backup performance, a fact which lengthens
backup windows and therefore the period of time that production applications are impacted during backup operations. Don’t
let tape vendors get away with quoting high tape drive streaming speeds; regardless of the speed at which a tape drive can
write backup data, it will only write it as fast as that data is
available. Networks generally can’t deliver data to tape drives
fast enough to keep them streaming, which is what results in
all the starting, stopping, and repositioning activities known
as “shoe shining”. Make sure you understand actual backup
windows in your environment – don’t just divide a tape drive’s
streaming speed into the amount of data that must be backed
up on a regular basis to determine the length of the backup
windows. A shoe shining tape drive may operate at 20% of its
rated speed or less, depending on the ability of your infrastruc-
WHITE PAPER
How to Evaluate the ROI of Your Data Protection Infrastructure
ture (networks, disks, applications, etc.) to deliver backup data
to it. A shoe shining tape drive operating at 20% of its rated
performance increases the size of the backup window by 5x.
And don’t let tape or backup software vendors push incremental or differential backups or multiplexing as a way to reduce
backup windows without understanding what the impact on
recovery times and reliability is. It is true that these approaches
can shorten backup times, but they significantly complicate
recovery and increase recovery reliability risks. That is because
to recover data that has been backed up using one of these
approaches, a backup administrator is very likely to require multiple physical tapes to complete the restore. Statistics dictate
that a backup operation that only requires one tape to complete
is more reliable than one that requires two. And performing recoveries using tapes that have been differentially or incrementally backed up, or multiplexed as they were written to tape,
will take longer, not only lengthening recovery times but also
increasing manual labor costs associated with those recoveries.
Finally, because the use of tape means by definition that backups are performed as a discrete operation, there is a direct
relationship between your backup performance and your peak
available network bandwidth. Almost all backups these days
are performed across networks, and networks are generally
sized to provide some headroom to allow for peak usage. Few
operational tasks consume bandwidth like backups do. Even if
your other business operations do not require very much network bandwidth, you may be forced to overprovision your network bandwidth just to meet certain recovery requirements.
In that case, a large percentage of your network bandwidth
may lie idle most of the time. If you don’t have this excess
network capacity, then it means that all other applications
that are transferring data across that network while backups
are occurring will be impacted as well, not just the application
being backed up.
RPO. When tape is the recovery media, then backup is a
discrete operation: there is no other option. Your RPO will be
driven directly by your frequency of backups. One backup per
day has a higher RPO than two backups per day, performed
12 hours apart. More lost data means more time attempting
to re-create that data or just – more lost data. The cost of lost
data may be hard to quantify, but the cost of the re-work to
re-create that data may be more quantifiable since it’s directly
related to the hourly cost of the human resource required to
re-do it. When data loss leads directly to lost business, particularly the loss of a large transaction such as a new construction
contract, a huge one-time deal, or the landing of a major new
client, the cost of data loss may be all out of proportion to
any sort of mathematical calculation. These types of costs are
difficult to forecast, although measures put in place to keep
RPOs low can clearly be viewed as an insurance policy against
such events.
| 6
Of all data protection approaches (other than completely
manual re-creation of the data because no backups are being
done), tape offers the worst RPO, although much of this is
because when tapes are used, it is impractical to do more than
one backup per day (and sometimes even that is impractical).
RTO. To recover data locally, recovering it from tape is a
multi-step operation. Assuming you are using a full backup
to perform the recovery, you’ll need to find the relevant tape,
manually load it into a tape drive, fast forward to the data
you’re looking for (assuming that you’re doing the much more
frequent “object level” type of recovery as opposed to a full
system recovery), restore that data to disk to get it into a format readable by production applications (most production applications cannot read data directly from tape), find the specific
object or objects that need to be recovered (by viewing the
backup through the production application which must often
be installed on a server separate from the production one to
minimize the production impacts of recovery operations), and
copy that object over to the production server. If incremental
or differential backups are used (instead of full backups), then
multiple tapes will be required to assemble the data you’re
looking for before it can be restored to disk, adding additional
time and risk to the recovery process. The use of “synthetic
full backups” may minimize the manual tape handling aspects
of this, but even with that capability additional time and risk is
introduced into the recovery process as a result of having to
touch multiple tapes to perform a restore.
If you are recovering data from a remote site, you have to add
the additional time up front to locate the tapes and ship them
back to the location where the recovery will be performed.
Local recoveries from tape can easily take hours, whereas
remote recoveries from tape can easily take days or even up
to a week or more. If a critical application is down and directly
impacting business operations, the long recovery times
required by tape can be a real problem. If you know the cost
of downtime per hour for your critical applications, you can
easily calculate the ROI of approaches which shorten RTO in
your environment.
Recovery Reliability. Recovering from tape is a lengthy process, and if the recovery fails, then you will need to go back to
your next most recent backup and perform the same lengthy
recovery process over again. High recovery reliability leads to
less recovery re-work, whereas poor recovery reliability leads
to more. Your backup administrators may keep records of how
often recoveries fail in your environment. If so, this is invaluable data in calculating the cost of poor recovery reliability. If
they are not tracking it, it is a good idea to start.
License fee and maintenance costs. If tape is being used,
conventional backup software is being used as well. In those
environments, every server that needs to be backed up must
WHITE PAPER
How to Evaluate the ROI of Your Data Protection Infrastructure
have a backup agent installed on it. These backup agents communicate with one or more backup servers, which host the
backup software, periodically gathering up all changes since
the last backup and sending them across a network to backup
servers which will then write that data to tape. Backup agents
can often cost $500 - $2000 or more per server, and backup
agent costs can become onerous as the number of servers
to be backed up increases. In addition, backup software often
includes complex functionality which requires patching and
software updates to accommodate new releases of application
software, operating system software, and hardware. These
updates generally require that servers have to be rebooted,
further impacting the availability of application services above
and beyond when backups have to be performed.
How Can Recovery ROI Be Improved?
The costs discussed in the previous section may be familiar,
although you may not have considered them all at once to
understand the significant costs that tape-based recovery
plans impose. The “hidden” costs of tape-based recovery infrastructures are huge. Next generation recovery technologies like
continuous data protection (CDP), asynchronous replication,
application failover/failback, and WAN optimization leverage
automation and disk-based recovery infrastructures to address
almost all of these problems. Because of their compelling
advantages, disk-based recovery approaches are supported by
almost all backup software vendors (as an alternative to tape),
but many companies may not have seriously considered them
because much of the cost of these solutions is incurred in the
up-front purchase price (which does not compare favorably
on a $/GB basis to the up-front purchase price of tape-based
infrastructure).
It should be clear now, after having taken a more in-depth look
at the soft costs associated with tape-based infrastructure
in terms of backup windows, RPO, RTO, recovery reliability,
tape handling, license fees, and maintenance impacts, that
purchase price is just the tip of the iceberg when it comes to
the costs associated with tape-based recovery infrastructure.
Disk-based approaches will result in significant soft cost savings by mitigating the impact of backup operations on business
operations and supporting better, more reliable recovery. But
just replacing tape-based backup targets with disk-based
targets and continuing to use your existing backup software as
you have in the past leaves a lot of costs still on the table. The
real way to maximize ROI on your investments to support both
local and remote recovery would be to do the following:
| 7
•Move away from backup as a discrete operation that impacts business operations and towards a more “continuous” approach to collecting changes that effectively makes
backup transparent and removes peak network bandwidth
requirements during backup operations
•Adopt an approach which makes your data recoverable
the moment it is created instead of the moment that it is
backed up, supporting near zero RPOs
•Completely change the paradigm of recovery granularity
being dependent on periodic backups, a change that will
minimize the RPO impacts of failed recoveries
•Combine technologies that meet the above requirements
with a disk-based recovery infrastructure to reap the benefits of disk’s short RTOs and excellent recovery reliability
•Automate as many of your data protection and recovery
operations as possible, moving away from manually intensive tasks such as tape handling, shipping tapes by truck,
manually rebuilding servers, and recovering applications
by hand
At this point, it may not surprise you to know that InMage
Systems, the author of this white paper, provides an application and data recovery solution that does these five things.
What may surprise you is the low entry price point and the
fact that it can be used in a complementary manner with your
existing servers, storage, applications, and backup software to
completely eliminate backups as a discrete operation, achieve
near-zero RPO, shorten recovery times to minutes (even for
recoveries from remote locations), and minimize or eliminate
tape handling at many or all of your sites. It will allow you
to remove backup agents from most of your servers, lowering licensing costs and maintenance operations across your
infrastructure. However, the point of this white paper is not
InMage – it is making sure you understand the full impacts that
tape-based recovery infrastructures are having in your environment. If you’re interested in finding out a little bit more about
