Overland Storage was founded in 1980 as "Overland Data" in San Diego, California, and is a provider of data protection appliances for midrange and distributed enterprises. Overland’s award-winning products include NEO SERIES tape libraries, REO SERIES disk-based appliances with Virtual Tape Library (VTL) capabilities, Snap SAN storage area network-based appliances and SnapServer network-attached storage-based appliances. Overland sells its products through leading OEMs, commercial distributors, storage integrators and value-added resellers.

Overland originally manufactured IBM-compatible 9-track tape drives. In January 2000, Overland acquired Tecmar and its line of small system tape drives including the WangTek and WangDAT brands. Following smaller acquisitions of disk-based product lines, in June 2008, Overland acquired Snap Server from Adaptec.

In January 2009, Eric Kelly, a board member since 2007 and the head of its recently acquired SnapServer NAS line, became CEO of Overland Storage. Other executive team changes in 2009 included Jillian Mansolf, formerly of Dell Inc., Maxtor and Data Robotics Inc., as the new vice president of worldwide sales and marketing; Geoff Barrall, formerly the CEO and founder of Data Robotics Inc. and BlueArc, as chief technology officer and vice president of engineering and Chris Gopal, most recently of Dell, as vice president of operations.

In February 2010, Overland debuted the latest in its SnapServer SAN line, Snap SAN S2000, the company's first iSCSI SAN. Later that month, Overland debuted LTO-5 technology across its NEO line of enterprise tape libraries, becoming the first company to offer the newer, faster tape technology to customers.

In mid-summer 2010, Overland opened the doors to a new Silicon Valley office in San Jose, California. In July 2010, Overland unveiled the SnapServer N2000, a block-and-file-level NAS or SAN package aimed at virtualized environments running VMware, Microsoft Hyper-V or Citrix XenServer. N2000 is integrated for Microsoft Windows and Unix and can scale up to 144 TB in a 2U form factor. Also in July, Overland unveiled the NEO 8000e, an enhanced version of the company's NEO 8000 series of enterprise tape libraries, that with LTO-5, scales up to 3 PB of capacity and has a data transfer rate of 24 TB per hour.

SnapServer network-attached storage (NAS) and Snap SAN storage area network (SAN) are disk-based data storage solutions that scale in capacity from 1TB to hundreds of terabytes and are designed for remote offices, workgroups, departments, and distributed enterprises.
