DATA BACKUP AND RECOVERY SOLUTIONS
FOR THE SMALL BUSINESS, THE ENTERPRISE,
AND EVERYTHING IN BETWEEN.
Your company is large-an enterprise. Your
company is small-a satellite office. You have
terabytes of data. You have gigabytes of
data. You use disk. You use tape.
No matter what your data storage scenario,
you have two things in common with every
other IT manager in the world:
- Data backup
and recovery is one of the most critical
aspects of your job;
- Overland Storage® has an appliance that can help you do it
faster, better and more reliably.
It all begins with the Overland Storage
REO family of data backup and recovery
appliances. Offering high-speed performance,
high capacity and flexible connectivity,
REO products not only increase your data
availability, but come with broad platform
support and the power of the newest
technology from Overland Storage-
Overland Storage SolutionPACs-software
that adds valuable functionality, flexibility and
security to your data backup and recovery.
You get faster backup and recovery, a powerful consolidation of all your server data and a reliable addition to your backup environment that's easily expanded with minimal disruption.

Intelligent, Embedded Data Protection Software
Overland REO Protection OS™ software, included
with all REO SERIES™ Disk-Based Backup and Recovery
Appliances, embeds data protection intelligence and
enables future software enhancements. It provides
REO SERIES users with an intelligent and flexible
platform designed to deliver fast, reliable data backup
and recovery while reducing operating costs. And it
allows REO appliances to be easily integrated into a
wide range of backup environments without changes
to policies or procedures.

REO-TO-REO SERVERLESS VIRTUAL TAPE MIRRORING
The future of advanced data backup and restore strategies, Overland Storage Multi-SitePAC software provides REO-to-REO
serverless virtual tape mirroring. Installed on any REO appliance, it uses iSCSI-connectivity for seamless, multi-level, enterprise
data recovery and asynchronous virtual tape mirroring. With multiple compression and mirroring options, Multi-SitePAC
is critical to ensuring seamless data backup and restore capabilities.

“The REO is fantastic,
almost too good to be
true. It's all it claims to
be and more—an easyto-
manage, versatile,
fast and efficient data
protection appliance
that provides peace
of mind.”

A COST-EFFECTIVE, DISK-BASED, DATA BACKUP AND RECOVERY APPLIANCE.
The Overland Storage REO 1500 with
Protection OS is a cost-effective,
easy-to-use, low-profile disk-based
backup and recovery appliance
designed to meet the data backup
needs of small business or branch
office users who require higher data
capacity for unattended backups,
near-instantaneous file restore
needed for rapid file recoveries
and increased data protection
at a price point that fits within
their budget.
The REO 1500 utilizes high-capacity
SATA disk drives, Gigabit Ethernet
(iSCSI) connectivity and Overland's
unique Protection OS software to
deliver features such as virtual tape,
dynamic virtual tape capacity
allocation, data compression
(virtual tape mode), hardware RAID
data protection and virtualization.
REO 1500 FEATURES AND BENEFITS:
• 3 TB native storage capacity
• 1U, Rack-mountable form factor
• Protection OS software
• Dynamic Virtual Tape support
• Gigabit Ethernet connectivity
• Simultaneous disk and tape support |

A HIGH-PERFORMANCE BACKUP AND RECOVERY APPLIANCE.
The REO 4500 series, with Protection OS, is
the ideal choice for mid-size storage
managers who have larger data
capacity requirements, want diskspeed
data recovery, a cure for
out-of-control backup windows
and a method for improving the
reliability of backup operations.
A shared storage resource that
improves the speed and efficiency
of existing tape-based backup
environments, the REO 4500 is
capable of storing up to 7.5 TB
of data per chassis and is expandable to 22.5 TB. The REO 4500c, which includes compression, can provide up to 45TB useable virtual tape capacity.
Both models use RAID 5 disk
storage to increase backup
reliability while providing near
instantaneous recovery of files. Like
the REO 1500, the REO 4500 has the
added flexibility of Protection OS
software, and support for iSCSI
connectivity.
Unlike the REO 1500,
the REO 4500 supports Fibre
Channel connections as well—
making it an even more versatile
backup and recovery appliance.
In addition, the REO 4500 works with
existing backup applications that
support tape devices, providing a
single backup catalog and a single
media management system. This
seamless compatibility allows for
easy deployment and integration
into existing backup environments.
As a result, REO 4500 users can
quickly achieve rapid recovery
of backup data from disk while
continuing to rely on tape for long term
archival storage.
REO 4500 & 4500c FEATURES AND BENEFITS:
• Total Native Capacity of 9 TB per unit
• Expandable to 27 TB Native
• Expandable to 45TB usable compressed virtual tape capacity with 4500c version.
• 2U, Rack-mountable form factor
• Protection OS software
• Dynamic Virtual Tape support
• GbE and Fibre Channel connectivity
• Simultaneous disk and tape support |

A HIGH-CAPACITY BACKUP AND RECOVERY APPLIANCE.
Much like the REO 4500, the
REO 9100 with Protection OS
was created for storage managers
who want disk-speed data recovery,
shorter backup windows and
improved reliability of backup
operations. But unlike the mid-size
REO 4500, the REO 9100 scales to
meet the needs of datacenters with
rapidly increasing requirements for
disk-based backup capacity.
A shared-storage resource that
improves the speed and efficiency
of existing tape-based backup
environments, the REO 9100 is
capable of storing up to 9.6 TB
of data per chassis and is expandable to 51 TB (66 Tb Native).
Like the REO 4500, it uses
RAID 5 disk storage, has support
for both iSCSI and Fibre Channel
connections, works with existing
backup applications that were
designed to support tape
devices, and takes advantage
of Protection OS software.
REO 9100 FEATURES AND BENEFITS:
• Up to 9.6 TB capacity per chassis
• Expandable with up to 4 additional chassis
• 5U, rack-mountable form factor
• Protection OS software
• Dynamic Virtual Tape support
• GbE and Fibre Channel connectivity
• Simultaneous disk and tape support |
