DTR recommends a backup recovery device that takes snapshot backups of your system every hour to an onsite backup device called a BDR.  The BDR also creates an offsite backup on the Internet of your server.  If your server goes down due to a hardware failure or a software issue/virus, the onsite BDR can turn into your server.  If your facility suffers a loss like a flood/fire and the server and the BDR is lost, your business can use the Internet BDR to run your business.  Once your server is repaired/replaced, the data from the BDR is synced to the new server and the BDR becomes a backup device again.

A BDR allows a very quick recovery from a down server.  Typical response times are about 30 minutes to diagnose the seriousness of the issue and get the BDR converted to a server.  More traditional backup solutions require you to order replacement parts, reload all or part of the operating system and reload the data which could take several days.  The amount of data on newer Microsoft/Linux servers also provide a challenge when using a traditional backup solution.  Older backups are once a day snapshot of the server and they might take 8-12 hours to complete depending the amount of data.
