I work for a large company that deploys ESXi hosts at remote locations all over the world. We also typically deploy a NAS as well at these locations. We recently upgraded to Commvault Simpana 9 for our backup and recovery solution. We have heard from some that the decision to turn on or off deduplication will determine if you need a physical media agent, or if you can set up a virtual media agent.
I have read around and understand that the reason that most do not set up a virtual media agent is due to resource contention on the ESX host. Our environments are not set up like most as we do not oversubscribe RAM or CPU in our environments.
Is anyone out there currently using virtual media agents with deduplication turned on? How has the performance been and has anyone found any issues with this type of setup?
