I am about to make my entrance into the virtualization world. I have decided to go with VMware SMB Essentials and Veeam Backup and Replication. I will virtualize three production servers on one host, and replicate these to a warm standby host on another physical location.
So far - so good

Looking through a VMware FAQ (http://www.vmware.com/products/vi/esx/esx_faq.html), I stumble across the following:
"VMware ESXi is the recommended platform for both new and existing customers. Future hypervisor releases will solely be based on this architecture."
Hmmmm, VMware recommends using ESXi, but at the same time VMware has restricted the usage of Veeam to disallow backup/replication from ESXi to ESXi hosts, so to get a warm standby server, you need to use ESX for the time being.
I don't really care whether to use ESX or ESXi as hypervisor, but it will be annoying to use ESX now, and then be forced to switch to ESXi in 1-2 years.
Are there any recommendations regarding this from Veeam?
Thanks in advance for your time...
