We primarily use it for data backup for VMware as well as AIX, which is an IBM platform. We also use it for the value-adds that Rubrik brings, including Live Mount.
We are on version 5.2 right now. We upgrade every little while. The version of the appliance is the r500 series.
Our environments are virtual and physical. We don't protect anything in the cloud currently.
Rubrik protects AIX versions 6 and 7, then primarily Windows and Linux hosted on VMware vSphere. We also do some standalone Linux and Windows boxes. As a subset of the Windows, we protect a lot of SQL Server databases. We do some IBM databases as well, but primarily SQL Server on Windows.
