RE: How to configure/setup a VRTX for file share/backup and recovery/VMs...
Someone in the community may be able to provide a comparison of AppAssure and NetBackup, however one advantage to AppAssure is that it is a single support call for both the software and the hardware. As for what hardware you would want, it would depend on the load of servers, your existing set up might be able to give you some idea of the resources that you need for each application. You would want either two or four servers on the chassis as a Hyper-V cluster for redundancy and so you can perform updates without taking everything offline.
