The Cohesity and Veritas product lines have nearly 100% overlap. Both vendors built their technology on a very infrastructure-centric approach: 
  * NetBackup (originally built in 1987) was backup software designed to run on a combination of primary control servers, various media servers (data movers), and storage targets — typically all physical.
  * Cohesity (founded in 2013) was written as a filesystem to run on converged/scale-out appliances.
