In 1988, Unitrends developed the first complete crash-recovery product for Santa Cruz Operation’s Xenix systems originally called Jet RestoreEase. 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 their first hardware-based backup appliance.
