Unitrends Inc., a Kaseya company, is a US-based company specializing in backup and business continuity.[1]


Unitrends produces a number of physical appliances ranging from small desktop backup appliances to large rack-mounted backup appliances. Unitrends also produces virtual appliances for VMware and Hyper-V marketed as Unitrends Backup. The physical appliances typically consist of some level of redundant components; most notably RAID in the form of RAID 1, RAID 6, and RAID 10.[2] The larger appliances also have tiered flash storage in the form of SSD drives.[3] These appliances perform either on-premises backup, off-premises disaster recovery, or through a technology known as cross-vaulting (a form of replication) an appliance may concurrently perform on-premises backup and off-premises disaster recovery.[4] Unitrends also offers a multi-tenant public cloud based service, Unitrends Cloud. The company states that Unitrends Cloud is based on its previous product offering using its backup appliances to perform off-premises disaster recovery in a single-tenant private cloud deployment methodology.[5]


Unitrends uses file- and image-based backup techniques coupled with storage-based and in-flight encryption, compression, data deduplication, and ransomware detection. The technology supports Bare-Metal restore as well as file-based recovery.[6] Unitrends supports a form of disk staging in what it terms as D2D2x (Disk-to-Disk-to-Any) where “x” can be a disk, a tape, a private single-tenant cloud, or a public multi-tenant cloud.[7] The company attempts to sell its support of storage, operating system, and application heterogeneity and claims that it supports over 250 versions of operating systems and applications.[8]


Since its inception in 1989,[9] Unitrends Software Corporation has been at the forefront of backup and crash-recovery technology. The first with a software solution for system crashes, the company today provides a set of tools to help manage and protect data while providing data availability. Unitrends originated from a sole proprietorship called Medflex, which was founded in 1985 by Steve W. Schwartz[10] to help fund medical missions. The first product, CTAR (Compressing Tape Archiver), was originally developed to handle the backup problems Schwartz encountered in his own medical office. After perfecting the program, it was sold commercially.

In 1988, Unitrends developed the first complete crash-recovery product for Santa Cruz Operation’s Xenix systems originally called Jet RestoreEase. Unitrends supported additional operating systems for SCO such as OpenServer and UnixWare. Unitrends started as a stand-alone Unix backup software company and provided BareMetal recovery for platforms like the SCO offerings. BareMetal was later ported to SCO Unix and renamed System Crash Air-Bag. From 1988 to 1991, ten other software products were written for the Xenix and Unix environments and in 1999, Unitrends released their Backup Professional client/server backup software. In September 2002, Unitrends shipped backup appliances to Toshiba Machine Co. of America.

Unitrends, has held a variety of locations during its existence. Initially based out of Myrtle Beach, South Carolina, headquarters were relocated further inland to Columbia in November 2003 while support and development remained on the coast until 2005. In 2014, headquarters were moved again to Burlington, Massachusetts.[11] where they remain today.

Shortly after this acquisition, Unitrends obtained PHD Virtual on December 16, 2013. Unitrends acquired another company on May 29, 2014, taking over Australian-based Yuruware. On May 3, 2018,[12] Unitrends merged with Kaseya.
