FalconStor® VTL Delivers the Fastest Backup Processes in the Industry - Including Backup, Deduplication, Replication, Tape Export, and Data Restore

Latest Performance Exceeds All Current Published Metrics from Competing Vendors,
Enhancing Backup and DR to Save Enterprise Data Centers Time and Money
MELVILLE, N.Y.--(Business Wire)--
FalconStor Software, Inc. (NASDAQ: FALC), the provider of TOTALLY Open data
protection solutions, today announced that it now delivers the fastest backup
and deduplication time in the industry with the FalconStor® Virtual Tape Library
(VTL) with deduplication solution. In addition to reducing backup, deduplication
and restore time through optimization, the FalconStor VTL solution`s ability to
leverage Fibre Channel for replicating deduplicated data further reduces the
total time to DR. A critical metric for assessing enterprise readiness for full
recovery from data center failure, total time to DR is measured by the time
required to back up a given amount of data, write it to tape, deduplicate it,
replicate it to a remote DR site, and restore the data to full availability.

FalconStor staged a test of its latest version of FalconStor VTL with
deduplication in order to validate the performance of FalconStor VTL in a real
data center configuration and to demonstrate a best-practice scenario. Measured
were key performance criteria, including ingest rate, tape production,
deduplication throughput, replication and recovery time.

"Total time to DR is critical to the resilience of any business that relies on
24-hour access to important applications," said Lauren Whitehouse, analyst with
the Enterprise Strategy Group. "A high-performance backup infrastructure is
critical to reducing a business`s exposure to downtime by ensuring data recovery
and full return to operability in a timely manner. FalconStor has clearly taken
the entire process from backup to recovery into consideration to achieve optimal
efficiency in terms of both time and cost."

"Other data protection vendors with deduplication focus on reduction ratios and
backup speeds but fail to take into consideration all the processes needed to
complete the DR-readiness cycle, including replication off site and restoration
of data into an application-ready state at the DR facility," said Wayne Lam,
FalconStor co-founder and vice president. "FalconStor considered the whole
picture in designing FalconStor VTL to integrate with any backup system and to
enable and optimize the entire sequence of events within a data protection
system. In addition, the FalconStor VTL system can scale without disruption or
complexity as the business grows."

"We have been selling FalconStor VTL with deduplication for some time now, and
we have been very happy with each deployment," said Israel Malowany, director of
sales for VirtuIT Systems, a leading solutions and service provider based in New
York. "FalconStor has designed the most scalable VTL with deduplication system
on the market, and it keeps getting better. It delivers enterprise-class
performance, stellar speed and deduplication rates, while growing seamlessly as
our customer`s needs grow."

In the test bed of 100 terabytes of production data, the performance measured
was achieved with a single cluster of two FalconStor VTL nodes supported by four
deduplication nodes. Running the backup and deduplication processes
concurrently, the total time to backup and deduplicate the 100 terabytes of data
was under 14 hours, yielding an average of 2.0 gigabytes per second. In the case
where minimizing the total backup time is the major goal, the two-node VTL
cluster delivered 2.8 gigabytes per second of backup speed, requiring a backup
window of under 10 hours for the 100 terabytes. Physical tape production can be
achieved directly through 4 gigabit Fibre Channel links by exporting tapes from
FalconStor VTL to the physical tape library without using a separate media
server. All hardware components used for the performance test are commonly
available standard parts, including standard Linux-based servers and low-cost
SATA-based storage subsystems with 4 gigabit Fibre Channel ports.

FalconStor VTL can scale up to an eight-node cluster with an additional
eight-node deduplication cluster managing a global, shared data repository that
can hold more than two petabytes of physical capacity or 40 petabytes of logical
(deduplicated) capacity. This massive scalability allows for consolidated
management of a large enterprise`s data and data protection processes, reducing
complexity, time, cost and risk related to managing a collection of discrete
repositories, as required by other deduplication solutions. The solution`s
clustered architecture ensures maximum availability and reduced downtime and its
associated cost.

Beyond backup data processing, FalconStor VTL features high-performance IP and
Fibre Channel replication designed to minimize the replication window and thus
reduce the risk of associated data loss. In addition to replicating backup data,
FalconStor VTL includes a backup media server catalogue replication feature that
guarantees continuous consistency of the backup media catalogue at the primary
and the DR site to accelerate restoration of data to full operation. Once data
is replicated to the DR site, FalconStor VTL enables high-speed restore of
deduplicated data at a sustained rate that exceeds 1.2 gigabytes per second per
node, demonstrating the fastest restore performance in the industry from a
deduplicated repository; at this speed a 100 TB data set can be restored in less
than 12 hours.

What FalconStor VTL customers worldwide are saying:

"One of our goals for this year was to add data backup services to our existing
portfolio of recovery services. We considered several providers and determined
the FalconStor solution provides businesses with complete critical data
protection services more quickly, efficiently and cost effectively than they can
do it themselves, and FalconStor VTL and deduplication technology helps us meet
that goal," said Walt Thomasson, managing director for Rentsys Recovery
Services. "FalconStor software provides the foundation for our new FLEXDATA™
backup and recovery solution, allowing us to help our clients reduce their RTO
and cut costs by reducing the amount of time, bandwidth and hardware required to
back up and restore company data."

"We deployed FalconStor VTL with deduplication to redesign our backup process
for a more power-efficient data center," said Sandor Orban, senior IT specialist
for Sunrise. "With deduplication we have been able to reduce dramatically the
amount of disk and tape we need to secure full backups of almost 70 terabytes of
data. Now, with FalconStor VTL performance improvements, we can scale not only
in capacity but also in speed and efficiency as our data continues to grow."

"Before we fully deployed FalconStor VTL with deduplication and replication, we
were vulnerable to long restore times in the event of a system fault because of
the inefficiency of restoring from tape," said Sangwon Lee, deputy general
manager at Korea East-West Power Company, Ltd. "But now with FalconStor VTL, we
have eliminated a lot of wasted time. Because we rolled out our new backup and
DR process in stages, we now can appreciate the full impact the total deployment
has had on our backup and restore speed - giving us the security that we can
become fully operational in less than a working day in the event of a major data
center failure."
