Hello,
I did do some searching as Hyper-V 2012 seems to offer a lot more functionality than 2008 and right now we are an SMB provider with two customers on SBS 2008. I was seeing about doing something or finding a way to replicate to virtual in the event that their server went down? I did find this thread http://social.technet.microsoft.com/Forums/en-US/virtualmachinemgrp2vv2v/thread/d0f40a7c-94ff-49d0-aa53-2df851e0f0c0/ which points to using a tool Disk2VHD offered from Microsoft, but it looks like you cannot do this on a daily basis and or do it over WAN/LAN.... I understand Hyper-V is meant more for replicated already exsisting VM's and not so much physical.
Also, if this were to work out, where or how would we get machine's to point at a datacenter or back to us so they can at least be up for some time while we figure out what to do. They are using cloud backup solutions... but nothing for instant failover or disaster recovery... Has anyone tackled this yet? It makes it all the more trickier considering it's not in a LAN environment....
