Unitrends Corporation (acquired by Insight Venture Partners), based in Columbia, South Carolina, provides disk-based backup appliances (replacements for existing tape backup devices) for small and medium businesses, as well as an online backup service to backup data over the public internet to a remote datacenter.

These products and services enable businesses to recover a single file or an entire server rapidly in the event of a catastrophic loss. An entire server that is destroyed can be completely recreated and made operational on a new machine with no previously installed software in about an hour.

As business processes and communications become increasingly dependent upon servers, the ability to recover quickly in the event of disaster is an important component of homeland security.
