As a CSP, we answer this question daily.  And we always answer the question with the question: 

“What do you want to accomplish with your Backup Product and Disaster Recovery plan?” 

For this article, we are not going to list all the Backup/DR products in the market today with an evaluation for each one.  There isn’t a need to do that as we have done our due diligence through research and testing and have narrowed the field to 4 products that offer secure, reliable recovery at very reasonable price points.
