6: Hyper-V Replica
Virtualization is the name of the game in the server world these days, and Hyper-V is Microsoft’s answer to VMware. Although the latter had a big head start, Microsoft’s virtualization platform has been working hard at catching up, and many IT pros now believe it has surpassed its rival in many key areas. With each iteration, the Windows hypervisor gets a little better, and Hyper-V in Windows Server 2012 brings a number of new features to the table. One of the most interesting is Hyper-V Replica.
This is a replication mechanism that will be a disaster recovery godsend to SMBs that may not be able to deploy complex and costly replication solutions. It logs changes to the disks in a VM and uses compression to save on bandwidth, replicating from a primary server to a replica server. You can store multiple snapshots of a VM on the replica server and then select the one you want to use. It works with both standalone hosts and clusters in any combination (standalone to standalone, cluster to cluster, standalone to cluster or cluster to standalone).
