5nine Software's Cloud Backup for Hyper-V was designed with service providers and hosting companies in mind and is fully scriptable with PowerShell. It works at the Hyper-V host level and employs VSS for application-consistent image-level backups of your virtual machines (VMs). You can restore entire VMs at the image level, similar to a bare-metal restore. Cloud Backup supports up to 16-node Hyper-V clusters with hundreds of VMs and Cluster Shared Volumes (CSVs). It also includes a centralized Backup Management console, even at the lowest license level. Besides the commercial version, which costs $99 per host, IT pros can use a free version that lacks the application programming interface (API).
