Hyper-V Replica with Exchange:

A: If you’re considering whether to use Hyper-V Replica with Exchange, just remember that Exchange has its own disaster recovery and site awareness capabilities that should be used instead. Hyper-V Replica isn’t needed and isn’t supported because of problems with Exchange’s roles being forced back in time in the event of an unplanned failover. More information can be found at “Microsoft Support Policies and Recommendations for Exchange Servers in Hardware Virtualization Environments” and “Understanding Exchange Virtualization” around technologies supported by Exchange.

I didn’t get “can’t” outta that link. Just that Hyper-V’s snapshots are “not supported” and so YMMV.
* As a DR strategy, HVR is much *faster* than restoring from backup.
* For a small business, HVR is much *cheaper* than a separately redundant Exchange infrastructure.
For SBS (with one of everything to simultaneously failover), I wonder if the “unsupported” concerns are all big-server-land.
Are you seeing something specifically against HVR for SBS folks?
“Not supported” when you are talking about DR means you have no support. Which is a place I would not want to be at when you are in a crisis. I’m very definintely hearing that Exchange does not support Windows 2012 technologies at this time.
