I have an environment with 6 physical servers running VMware vSphere 5, there are about 15 servers(VM) are running on these hosts and 1 OpenIndiana(OI) Storage. Currently, most of the VMs are located on this OI storage, my environment has about 6 TB.
I am looking for a backup solution for my network, you can see I have now a single point of failure and this is a risk. I am looking for a offline backup solution, it should not too expensive solution.
Base on my description, could you please give me best advices what should I setup a good backup for my environment ? Thank you
